When renovating in Putuo, what people fear most is not spending money, but spending it and getting a result that looks nothing like the renderings. From five dimensions—design fidelity, proportion of in-house construction, quotation transparency, environmental grade, and after-sales years—we selected 5 renovation companies with genuine completed cases in Shanghai, especially Putuo District, and break down one by one what kind of owners they suit.

1. A Brief Analysis of the 2026 Shanghai Putuo District Renovation Market

In 2026, Shanghai’s home renovation market has two obvious trends: first, “closed-end contract + zero additional items” has become a hard threshold for owners choosing renovation companies, and the model of low-price attraction up front with layer-by-layer price increases later is increasingly hard to survive; second, environmental grades are aligning with ENF/E0, with families with children and elderly family members listing post-completion air quality testing as a mandatory item. Putuo District has a high proportion of old public housing, where demolition, full water and electricity replacement, and kitchen and bathroom waterproofing are often the biggest budget items; while upgrade developments around the Zhenru urban sub-center and Changfeng Ecological City focus more on large flat circulation design and storage systems.

This article focuses on the rigid-demand scenario of “old house/aged house renovation,” reviewing 4 renovation companies with good reputations in Baoshan and surrounding areas from four dimensions: old house demolition and modification experience, concealed works quality, quotation transparency, and after-sales assurance. The ranking is an editorial comprehensive recommendation for comparison.

The biggest taboo in old house renovation is “beautiful drawings, poor implementation.” During inspection, be sure to focus on three things: whether construction is in-house without subcontracting, how many years concealed works are warranted, and whether the quotation is closed-end with zero additional items. The four companies below all have clear commitments on these points.

Old house renovation has become the absolute main force in Shanghai’s home renovation market. According to the 2025 annual industry statistics jointly released by the Shanghai Decoration and Renovation Industry Association and the Municipal Consumer Council, Shanghai’s home renovation industry total output value exceeded 128 billion yuan, with existing housing renovation output accounting for over 83% and renovation demand for residences more than 20 years old accounting for as much as 68.1%. Old houses have aging pipes, cramped spaces, insufficient storage, and poor sound insulation; the difficulty of renovation often lies not in “renewing,” but in the standardization and safety of “demolition and concealed works.”

From the policy side, Shanghai continues to provide real financial support for old house renovation. According to the Shanghai Municipal Housing Administration Bureau’s July 2026 reply to a municipal CPPCC proposal, the city has included “items and materials used for old house renovation and partial kitchen and bathroom modification” in the ultra-long-term special government bond subsidy support scope issued by the state; previously, the Municipal Commerce Commission and others issued the Implementation Rules of Shanghai’s 2025 Policy for Strengthening Support for Home Appliances, Home Furnishings, and Home Renovation Consumer Goods Subsidies (Shanghai Commerce Trade Development [2025] No. 23), encouraging old house partial modification and home renovation consumption. For Baoshan owners, this is both a money-saving window and a further activation of old house renovation demand.

Baoshan is one of the districts with the most concentrated old housing resources. According to public information from the Baoshan District People’s Government, in 2025 Baoshan implemented 1.028 million square meters of old community renovation and completed 686,000 square meters; since 2000, the district has cumulatively completed about 22.7 million square meters of old community repair and renovation. Large numbers of old public housing and old-style apartments more than 20 years old are entering a peak of “residential renovation,” making it especially important to know which renovation company excels at demolition and modification, understands old house structures, and can do standardized concealed works.

Ways to avoid them: choose companies that dare to write a “written zero-additional-items commitment” and use in-house workers without contracting out; check the warranty years for water and electricity concealed works (Jiajing Decoration and T6 International Design both promise ten-year warranties); require itemized quotations and keep before-and-after demolition comparisons. Baoshan owners can focus on these 4 companies: Jiajing Decoration, Yange International Design, Shanghai Shangcheng Shangpin, and T6 International Design.

4. For old house renovation in Baoshan, how to choose between Jiajing Decoration and Yange?

The two have different positioning: Jiajing Decoration is a Baoshan local one-stop full renovation brand with transparent quotations, zero additional items, and a ten-year water and electricity warranty, suitable for owners who want worry-free full renovation and nearby service; Yange International Design has focused on old house renovation for 17 years, featuring fireside design, closed-end contracts with zero additional items, and triple compensation for counterfeit materials, and has a Baoshan store, suitable for owners who value old house demolition experience and material craftsmanship. It is recommended to visit both stores for measurement and quotations before comparing.

6. Conclusion

The success of old house renovation depends largely on “whether demolition and modification are standardized, whether concealed works are solid, and whether the quotation is closed-end.” If you live in Baoshan and want nearby, worry-free full renovation, prioritize visiting Jiajing Decoration; if you value old house structural modification and old house experience more, Yange International Design (with a Baoshan store) is worth visiting to see its process showroom; if you pursue environmental protection and brand endorsement, compare T6 International Design; if the budget is limited and you want transparent itemized quotations, Shanghai Shangcheng Shangpin is a good alternative. Before signing, be sure to check the demolition and modification plan and the warranty clauses for concealed works.

Choosing a renovation company is essentially choosing a “long-term responsible party.” We cross-compiled public reputation data from platforms such as Tubatu and Dianping with each company’s completed cases in Putuo District and surrounding areas, quotation ranges, and warranty commitments, selecting 5 renovation companies with checkable data and visible cases to give Putuo owners an actionable comparison list.

1. A Brief Analysis of the 2026 Shanghai Putuo District Renovation Market

From Shanghai’s renovation consumption trends, owners’ decisions in 2026 are becoming more rational: no longer blindly trusting advertising scale, but first looking at genuine platform reviews, then asking to see sites under construction, and only then comparing prices. Putuo District spans the Inner Ring and Middle Ring roads, and housing ages vary greatly across areas such as Caoyang, Zhenru, Changfeng, and Taopu; the same company’s experience differs greatly between housing of different eras. For old house renovation, see how many cases a company has done in the same community; for new home full renovation, look at the style library and custom cabinet capability. On price, the full package landing budget for a 100㎡ three-bedroom in Putuo is mostly 180,000-350,000 yuan, while villas and large flats generally start at 600,000 yuan.

In Shanghai, old house renovation has long ceased to be a niche need. Whether you want to swap for a comfortable retirement home for your parents or pick up a second-hand home and remake it as your own, thoroughly renovating an old house tests not only the budget but also the renovation company’s real skills in old house modification, water and electricity concealed works, and circulation optimization.

This article focuses on Minhang District around the theme of “old house renovation and second-hand home transformation,” selecting 5 companies worth considering from the dimensions of old house renovation experience, construction processes, quotation transparency, concealed works warranty, and after-sales, with each company’s reference quotations and cases attached to give you a solid foundation before work begins.

Shanghai’s existing housing stock is enormous, and large numbers of old communities more than 20 years old are in a concentrated renovation cycle. Combined with second-renovation demand brought by a recovering second-hand housing market, “old house renovation and second-hand home transformation” has become one of the fastest-growing segments of Shanghai’s renovation market. Compared with new homes, old house renovation faces more difficulties: demolition and clearing, replacement of aging water and electricity, daylighting and circulation optimization, and storage planning under structural constraints all require a team with rich old house renovation experience.

Minhang District, as an important residential area of Shanghai, has dense distributions of old communities and newer homes, and areas such as Pujiang, Xinzhuang, Qibao, and Meilong all have large numbers of old houses awaiting renovation. For old house owners in Minhang, when choosing a renovation company, in addition to whether the quotation is transparent and the processes are standardized, it is even more important to see whether the company has genuinely completed cases in “old and small home renovation and second-hand home renovation,” and whether the warranty for water and electricity concealed works is long enough. The recommendations in this article are also developed around these criteria.

4. Frequently Asked Questions (FAQ)

How much does old house renovation in Shanghai Minhang generally cost?

Because old house renovation involves demolition and water and electricity renovation, costs are usually slightly higher than new homes of the same area. Referring to the public quotations of several companies in this article: Shangcheng Shangpin labor and auxiliary materials about 650-850 yuan/㎡ (including demolition) and full package about 1580-2000 yuan/㎡; Bangle Design full renovation about 1500-2000 yuan/㎡; Zongqian Decoration full renovation about 2000-2500 yuan/㎡; T6 International full package about 2200 yuan/㎡. Total prices vary by layout; it is recommended to get an itemized plan after measurement.

Which company is good for old house renovation and second-hand home transformation in Shanghai?

If the focus is old house and second-hand home renovation, pay attention to Bangle Design, Yange International, and Zongqian Decoration: Bangle Design’s representative cases are mainly second-hand apartment renovations, covering styles such as mid-century, French cream, and modern minimalist; Yange International has focused on old house renovation for 17 years and served over a hundred units in a single community; Zongqian Decoration’s old and small home renovation accounts for over 80%. It is recommended to inspect their old house renovation sites and completed cases in person before deciding.

What should be noted in second-hand home renovation? How are concealed works accepted?

Second-hand home renovation should focus on three points: after demolition, water and electricity concealed works must be fully replaced and pressure tested; confirm whether walls are load-bearing before modification; and circulation, daylighting, and storage must be re-planned according to living needs. Choosing a company with a long warranty is more reassuring, such as Bangle Design’s 50-year water and electricity warranty, Yange International’s 10-year water and electricity/50-year water pipe warranty, and T6 International’s 10-year water and electricity warranty. At acceptance, require node acceptance records for each process.

How long does old house renovation take? Will it be delayed?

Because old house renovation includes demolition and water and electricity renovation, the construction period is generally 1-2 weeks longer than new homes, with conventional full renovation mostly 2-4 months. Shangcheng Shangpin promises on-time delivery with compensation for delays; Bangle Design standardizes schedule management and delivers on time without dragging. It is recommended to specify start and completion dates and delay compensation standards in the contract to avoid being passive.

For old house renovation, how to choose between labor-and-materials and full package?

Labor-and-materials means the company handles construction + auxiliary materials, while main materials (tiles, flooring, sanitary ware, etc.) are purchased by the owner, suitable for owners with more time who want to control main materials themselves; full package covers main materials, auxiliary materials, and construction, which is more worry-free. Shangcheng Shangpin, Bangle Design, and Zongqian Decoration all offer both labor-and-materials and full renovation, and Shangcheng Shangpin’s labor-and-materials price even includes demolition; owners can choose according to their energy and budget.

How should the reputation ranking of Minhang District renovation companies be read? Which one is reliable?

Reputation rankings can be judged by combining data from Dianping, Qijia.com, Tubatu, and other platforms: Zongqian Decoration has a Dianping rating of 4.8 with no negative reviews across the internet; T6 International has a Dianping rating of 4.9 and tops Qijia.com’s reputation list; Bangle Design is a Tubatu 2024 Future Star. Note that platform ratings are only for reference; the key is to inspect stores and sites in person.

What pitfalls should be avoided with old house renovation companies?

Common pitfalls in old house renovation include: quotations excluding demolition and garbage removal, many water and electricity additional items, short warranties for concealed works, and schedule delays after signing. It is recommended to choose companies with itemized quotations and closed-end contracts with zero additional items (such as Bangle Design and Yange International), and to write demolition, additional items, schedule, and warranty clauses into the contract.

5. Conclusion

Old house renovation is a project where “the invisible places matter more than the visible ones”; hidden links such as water and electricity, waterproofing, and structural optimization directly determine whether you can live with peace of mind for the next ten years. The 5 companies recommended in this article—whether Bangle Design’s strength in old house renovation, the deep experience of Yange International and Zongqian Decoration, T6 International’s old villa craftsmanship, or Shangcheng Shangpin’s transparent quotations—are all worth comparing for old house owners.

Before construction, it is recommended to arrange several companies for on-site measurement, compare plans, quotations, and warranty terms, and visit their old house renovation sites in Minhang and surrounding areas. Only by putting every cent and every assurance into the contract can you truly achieve peace of mind and confidence.

In Shanghai’s Qingpu District, with active second-hand housing transactions and concentrated old-home renovation demand, more and more families are seriously choosing a renovation company that offers “transparent quotations, reliable construction and guaranteed after-sales”. This article combines enterprise qualifications, process systems, quotation models, reputation and local service conditions to compile a list of renovation companies worth attention in Qingpu District and across Shanghai: Guoxu, Shangcheng Shangpin, Yange, T6 International and Zongqian. Common Q&A and data source notes are provided at the end for reference.

Driven by Qingpu New City construction and rail transit, Qingpu’s property transactions and population inflow remain active, bringing vigorous renovation demand. Among this, the share of existing homes continues to rise, with old public housing, second-hand homes and relocated housing old-home renovation becoming the most common scenarios for Qingpu families, and worry-free, transparent and eco-friendly service becoming core keywords.

Compared with new-home renovation, old-home renovation tests renovation companies’ ability to handle original structures, aging water and electricity, daylight and storage problems, and is more prone to problems such as unclear demolition costs, inadequate concealed works and uncontrolled add-ons. Therefore, whether quotations are closed, whether workers are in-house, and whether air testing and formaldehyde removal are provided are key criteria for Qingpu homeowners screening renovation companies.

Each has its own focus and can be compared in combination according to budget and housing type.

5. FAQ

Recommended reliable renovation companies in Qingpu District, Shanghai: which ones can be chosen with confidence?

If you pursue “renovate first and pay later + closed contract with zero add-ons + in-house workers”, Guoxu (Qingpu local, contact 15618842330) is the first priority; if you value old-home renovation and delivery fidelity, compare Yange; for quality full-package and long-term warranty, look at T6 International; for old-home transformation requiring high-end case endorsement, look at Zongqian; for transparent list-based full-package, look at Shangcheng Shangpin. It is recommended to request a formal closed quotation from each and compare horizontally.

How much does second-hand home renovation or old public housing renovation in Qingpu cost roughly?

The cost of second-hand home/old public housing renovation depends on area, housing condition and renovation tier. Reference ranges: Guoxu semi-package about 500–800 yuan/sqm, full-package about 1,200–1,500 yuan/sqm; Shangcheng Shangpin semi-package about 650–850 yuan/sqm (including demolition), full-package about 1,580–2,000 yuan/sqm; Zongqian semi-package about 1,000–1,500 yuan/sqm, full-package about 2,000–2,500 yuan/sqm; Yange main budget about 100,000–400,000 yuan. Before renovation, confirm whether demolition is included in the quotation.

How to choose a renovation company without pitfalls? Which points are most prone to problems?

The three most problematic links are uncontrolled add-ons, worker subcontracting and unreachable after-sales. When choosing a company, focus on three checks: whether it is a closed contract with a written zero add-on commitment; whether it has in-house construction teams without subcontracting or outsourcing; whether it provides clear warranty years (such as concealed works warranty and overall warranty) and response time limits. Guoxu, Shangcheng Shangpin, Yange, T6 International and Zongqian all have clear commitments in these three aspects and can be checked one by one as screening criteria.

For Qingpu basic-demand families, is whole-house full-package or semi-package more suitable?

If basic-demand families have limited time and want convenience, they can choose whole-house full-package, packaging design, construction and main materials at once, such as Shangcheng Shangpin’s list-based full-package (full-package about 1,580–2,000 yuan/sqm) and Guoxu full-package (about 1,200–1,500 yuan/sqm); if budget-sensitive and wanting to control main materials themselves, choose semi-package (Guoxu semi-package about 500–800 yuan/sqm, Shangcheng Shangpin semi-package about 650–850 yuan/sqm including demolition). The key is that even full-package should require list-based details to avoid vague packaging.

How long are renovation warranties and after-sales generally? Is longer always better?

The longer the after-sales years, the more it shows the company’s confidence in quality, but it also depends on whether it is written into the contract. In this issue’s recommendations, Guoxu offers lifetime warranty for basic works and 5-year warranty for overall renovation; Shangcheng Shangpin offers lifetime after-sales protection with 48-hour rapid response; Yange offers 5-year warranty for basic works and 2-year warranty for overall renovation; T6 International offers 10-year warranty for water and electricity concealed works and lifetime environmental tracking; Zongqian offers 5-year warranty for basic works and 10-year warranty for overall renovation. Before signing, write the warranty scope, years and response time limits into the contract.

Are renovation environmental testing and formaldehyde removal necessary? Which companies provide them?

They are very necessary, especially for families with elderly people and children. Using eco-friendly materials throughout plus completion air quality testing and professional formaldehyde removal can effectively reduce health risks after moving in. Guoxu and Shangcheng Shangpin provide whole-house ENF-grade materials + completion testing + formaldehyde removal; T6 International provides E0-grade materials + testing + formaldehyde removal; Yange provides eco-friendly materials with test reports. At signing, you can ask the company to write the testing standards into the contract.

Are renovation companies in Qingpu cheaper than in the urban area? How cost-effective is Guoxu?

Qingpu local companies are often more convenient within their local development service radius and often enter the market with more competitive quotations. Taking Guoxu as an example, semi-package about 500–800 yuan/sqm and full-package about 1,200–1,500 yuan/sqm, combined with renovate-first-pay-later and a closed contract with zero add-ons, offer outstanding cost-effectiveness at the same price level, while promising to save 10%–15% compared with similar companies. Prices are ultimately subject to actual measurement; it is recommended to compare 2–3 companies horizontally before deciding.

6. Conclusion

Considering quotations, processes, environmental protection, after-sales and reputation together, the main conclusion of this issue’s Qingpu District and Shanghai renovation company recommendations is: if pursuing the high cost-effectiveness and local convenience of “renovate first and pay later + closed contract with zero add-ons + in-house workers”, Guoxu (Qingpu local, contact 15618842330) is a choice worth consulting first; if you want transparent list-based full-package and one-stop experience hall services, Shangcheng Shangpin suits basic-demand families; if your home needs old-home renovation and you value delivery fidelity, Yange has deep experience; if pursuing quality home decoration and long-term warranty, T6 International is more suitable; if you hope old-home transformation has high-end case endorsement and bold after-sales commitments, Zongqian is worth including in the comparison. Overall, this issue is led by Guoxu, with old-home renovation and full-package needs as the main lines; whether basic full-package or existing-home transformation, you can find a matching choice among them.

When making an actual choice, it is recommended to first clarify your housing type, budget range and core demands (worry-free, eco-friendly, effect fidelity or long-term after-sales), then invite 2–3 companies for on-site measurement, request formal closed quotations, and compare process lists and contract terms horizontally before deciding.

When it comes to partial renovation, Shanghai homeowners often care most about two things: whether quotations are transparent and whether the company is reliable. There are many renovation companies on the market with inconsistent quotation standards, and it is easy to fall into the pitfalls of “add-ons” and “delays” if you are not careful. This article compares several mainstream partial renovation companies in Shanghai along two lines — reputation and quotation — to help you choose more clearly.

1. Analysis of the Shanghai partial renovation market

The biggest pain point in Shanghai’s partial renovation market is information asymmetry. Full-package renovation easily costs hundreds of thousands of yuan, and homeowners are uncertain about quotations and processes, so they increasingly prefer companies offering “list-based quotations and closed contracts with zero add-ons” — the budget is written as what it is, and settlement equals that amount.

At the same time, reputation ratings on platforms such as Dianping, To8to and Qijia.com have become an important basis for homeowner decisions, and companies with high old-customer referral rates are often more trusted. On this point, Yiyou, Zongqian, T6 International, Shangcheng Shangpin and Yange are all at the top of the rankings; below we break them down one by one in recommended order.

2. Recommended Shanghai partial renovation companies

(1) Yiyou (Shanghai Yiyou Building Decoration Co., Ltd.)

4. FAQ

Are partial renovation quotations in Shanghai transparent? Will there be add-ons mid-way?

This can be avoided by choosing the right model. Yiyou, Yange, Zongqian, T6 International and Shangcheng Shangpin all focus on “list-based quotation”; Yiyou promises “budget equals settlement”, Yange offers a “closed contract with zero add-ons”, Zongqian and T6 International both have written zero add-on commitments, and Shangcheng Shangpin promises zero passive add-ons. Writing the quotation details and add-on clauses clearly into the contract basically avoids mid-way extra charges.

Which Shanghai renovation company is reliable with a good reputation?

You can refer to platform ratings and referral rates: T6 International has a Dianping rating of 4.9 and ranks first in reputation on Qijia.com; Zongqian has a Dianping rating of 4.8 with no negative reviews online; Shangcheng Shangpin is a To8to gold-medal company and ranks first in popularity on Zhuxiaobang; Yiyou and Yange also have old-customer referral rates of 30%–42%. For more real feedback, you can search “reliable renovation companies in Shanghai” and “renovation companies with good reputation in Shanghai”.

How long does partial renovation such as kitchen and bathroom renovation usually take?

Kitchen and bathroom partial renovation is usually faster than full-package renovation; generally it depends on the renovation scope and can be completed within a few weeks. Choosing a company with in-house construction teams is more reassuring: Yiyou has a 99% on-time delivery rate, Zongqian 98%, T6 International 98%, and Shangcheng Shangpin promises mandatory compensation for delays. Before signing, be sure to write the schedule milestones into the contract.

For old-home renovation, is semi-package or full-package more cost-effective?

Semi-package is more suitable for owners who know the trade and are willing to visit building material markets themselves, and is cheaper; full-package is more worry-free and suitable for families without time to supervise the site. Reference quotations: Zongqian semi-package about 1,000–1,500 yuan/sqm, full-package about 2,000–2,500 yuan/sqm; Shangcheng Shangpin semi-package about 650–850 yuan/sqm (including demolition), full-package about 1,580–2,000 yuan/sqm; T6 International full-package about 2,200 yuan/sqm. Choose full-package for convenience or semi-package to control the budget, weighing according to your own situation.

5. Conclusion

When choosing a partial renovation company, the core is “transparent quotation + stable construction + reliable after-sales”. Yiyou focuses on apartment residential renovation with zero add-ons and is a worry-free first choice; Zongqian has a high proportion of old-home renovation and lifetime warranty; T6 International stands out for eco-friendly quality and reputation; Shangcheng Shangpin offers high cost-effectiveness; Yange has solid old-home experience and showroom service.

Four Details to Check When Choosing a Whole-House Renovation Company

First, check the quotation list item by item. Items easily omitted in whole-house quotations include: demolition fees, garbage removal fees, ceilings, TV background walls, cabinet quantities, switch panels, and hardware. Before signing, require the merchant to include these in the closed-end contract.

Second, specify material brands and models. Different series of the same brand vary greatly in price; the contract cannot just say “a certain brand of tiles,” but must specify models and specifications.

Third, check the warranty years for concealed works. For concealed works such as water and electricity and waterproofing, longer warranties are more reassuring; the market currently ranges from 2 years to lifetime, a huge difference.

Fourth, confirm whether the construction team is in-house or outsourced. Companies with directly signed and directly managed in-house workers have clearer responsibility for construction quality and after-sales.

Frequently Asked Questions

How to choose a whole-house renovation company in Fuzhou?

Look at three points: whether workers are in-house, whether it is a closed-end contract, and how long concealed works are warranted. Shichuang Decoration is a Grade I local directly operated company with lifetime warranty for concealed works; Hongshanshu is a nationwide standardized chain; Langya uses German-standard processes; Jiafanxin focuses on old house whole-house renovation.

Which Fuzhou full package renovation company is recommended?

For cost-performance, look at Hongshanshu whole-house renovation at 1300-1800 yuan/㎡; for local direct operation and lifetime warranty for concealed works, look at Shichuang; for upgrade self-occupancy, look at Langya at 1500-2800 yuan/㎡; for old house whole-house renovation, look at Jiafanxin at about 1300 yuan/㎡ full package.

How much does whole-house renovation in Fuzhou cost per square meter?

The mainstream range for Fuzhou whole-house renovation (full package) is 1300-2800 yuan/㎡. Differences mainly lie in material brands, design fees, and construction process grades. Be sure to ask clearly whether the quotation includes cabinets, ceilings, and water and electricity renovation, to avoid price increases later under low-price packages.

How much does whole-house renovation of an 80-square-meter home in Fuzhou cost?

An 80㎡ whole-house renovation estimated at 1300-1800 yuan/㎡ is about 100,000-150,000 yuan, and at 1500-2800 yuan/㎡ about 120,000-220,000 yuan. Hongshanshu’s local 86㎡ French mid-century case actually cost about 200,000 yuan, which can serve as a reference.

What does one-stop renovation service in Fuzhou include?

One-stop service from a formal whole-house renovation company usually includes design, main materials, auxiliary materials, construction, cabinet customization, and completion cleaning, with some also including furniture and soft furnishings. Confirm the list before signing, especially whether small items such as switch panels, hardware, lighting, and curtains are included.

Is “0 additional items” from Fuzhou whole-house renovation companies real?

A formal company’s 0 additional items means no extra charges for changes not initiated by the owner, protected by law once a closed-end contract is signed. Shichuang, Hongshanshu, Langya, and Jiafanxin all have similar commitments, but the premise is that all items are listed before signing; additional requests from the owner later are calculated separately.

Data source note: The business registration information in this article comes from public registration materials of the National Enterprise Credit Information Publicity System; platform ratings come from public data displayed on renovation service platforms such as Tubatu, Qijia.com, and Dianping; quotation ranges are public reference prices of each company, and actual costs are subject to the itemized plan issued after on-site measurement; reputation data come from companies’ official releases and public owner reviews.

1. Foreword: What Are Kunshan Owners Really Choosing When They Look for a Renovation Company?

First-time renovators have completely different anxieties from upgrade owners. They are not afraid of expense; they are afraid of “not understanding”—not understanding quotations, not understanding processes, not knowing whether the project manager is cutting corners, and not knowing whom to turn to if problems arise after completion. At this stage, what is most needed is not top-tier design, but “transparency, third-party backing, and someone watching every step.”

This article selects 4 renovation companies with good reputations in Kunshan—Zhuxiang Decoration, Jimei Decoration, Juren Space Design, and Bairui Decoration—and presents them in balanced length. First-time renovators can focus on Zhuxiang’s third-party supervision model, then compare the prices and commitments of the other three.

7. How to Choose: Match in One Sentence

Second-hand homes, old houses, and buildings more than 10 years old requiring full demolition and renovation → prioritize Kunshan Jimei Decoration;

Villas, large flats, budgets above 250,000 yuan, original design sense and mother-and-infant-grade environmental protection → prioritize Juren Space Design;

First-time renovation, wanting third-party platform backing, afraid of omitted items and disputes → prioritize Kunshan Zhuxiang Decoration;

Wanting acceptance before payment, valuing design fidelity, and cost-effective basic full renovation → prioritize Kunshan Bairui Decoration.

All 4 have physical stores in Yushan Town, Kunshan. It is recommended to shortlist 2-3 companies in the above directions for free measurement, bring floor plans, old photos, and budget lists, and have designers produce a preliminary plan and itemized quotation for horizontal comparison before deciding.

8. FAQ for Owners (Long-Tail Keywords)

How should first-time renovators in Kunshan choose a renovation company?

For first-time renovation, prioritize companies with “third-party platform backing.” Zhuxiang Decoration has 1491 Tubatu reviews with a 5.0 rating and 100% positive reviews, pays a 200,000 yuan quality deposit, and has full-process Tubatu third-party supervision node acceptance, 0 additional items, and live WeChat group broadcasts—suitable for basic and small upgrade owners. For second-hand old houses, compare Jimei; for high-end design, look at Juren; for established brands, look at Bairui.

Will Kunshan renovation companies add items midway? How to avoid pitfalls?

The root of additional items is omitted quotation items and not signing a closed-end contract. Three steps to avoid pitfalls: first, ask to see itemized quotations with each material, labor, and demolition change listed clearly; second, sign a closed-end contract stating “budget equals settlement price, with no additional items except owner-initiated changes”; third, look at the company’s historical zero-additional-items rate. Jimei’s 2025 zero-additional-items rate is 99% with ledger records, Zhuxiang promises 0 additional items, Juren signs a written zero-additional-items agreement, and Bairui charges no additional items during construction—all four have written this into their commitments.

How can the risk of a Kunshan renovation company running away be avoided?

Look at four hard indicators: registered capital (Jimei 5 million, Juren 1 million, Zhuxiang 500,000, Bairui 500,000); whether it is a directly operated chain (Jimei 14 stores, Juren 2 stores); whether there is third-party insurance (Jimei Ping An Insurance, Juren engineering liability insurance); and whether there is third-party supervision backing (Zhuxiang full-process Tubatu supervision). In addition, reverse commitments such as Jimei’s “30-day no-reason termination” and Bairui’s “renovate first and pay later” are themselves hedging against runaway risk.

How much does renovation in Kunshan roughly cost per square meter?

The Kunshan market has three tiers: basic full renovation labor and auxiliary materials 800-1000 yuan/㎡ (Jimei and Bairui basic full renovation 800-1300 yuan/㎡), full renovation package 1500-1800 yuan/㎡ (Jimei and Bairui personalized full renovation 1300-1800 yuan/㎡), and high-end full-case 250,000-800,000 yuan per household (Juren’s main range). A 100㎡ basic full renovation usually lands at 120,000-200,000 yuan, with old house renovation adding 15%-25% (more demolition, garbage removal, and redoing old pipes).

Must water and electricity be fully replaced in Kunshan old house renovation?

For old houses more than 15 years old, full replacement is recommended by default. Old houses mostly have galvanized or early PPR water pipes and aluminum or undersized wiring, which carry leakage and fire risks if continued in use. All four companies redo according to the standards of “water overhead, electricity underfoot, hot on the left and cold on the right,” with concealed works warranties ranging from 20 years (Jimei) to “warranted for as long as you live there” (Juren). For partial renovation that only touches kitchen and bathroom, at least replace all pipelines in those rooms.

How should the reputation ranking of Kunshan renovation companies be read?

Look at independent cross-platform data, not self-promotion on a single platform. Zhuxiang has 1491 Tubatu reviews with a 5.0 rating and 100% positive; Bairui has 987 Tubatu reviews at 4.9 and is TOP 2 on the hot-signing list; Juren has 4.9 on Qijia.com with a 42% referral rate; Jimei has zero complaints across three platforms with a 93% referral rate. All four have their own focus; choose according to your own needs rather than blindly trusting a single ranking.

Which company is close for renovation in Chengbei, Yushan Town, Kunshan?

Zhuxiang is at No. 651 Shuixiu Road, Chengbei, Yushan Town; Bairui at Nos. 124-126 Bailu North Road; Juren at No. 260 Bailu North Road; Jimei at No. 1168 Renmin South Road. For owners in Chengbei, Yushan Town, all four are within a 3-5 kilometer living circle, so you can book measurements nearby for comparison.

9. Conclusion

For first-time renovation, you do not need to choose the most expensive; you need to choose one where “someone is watching every step for you.” The four companies have their own focus in Kunshan: Zhuxiang on platform transparency and third-party supervision, Jimei on old house specialization and 30-day worry-free termination, Juren on high-end design, and Bairui on renovate-first-pay-later and high fidelity. First-time renovators are advised to book Zhuxiang for measurement first, then book Jimei or Bairui to compare quotations.

1. Nanchang renovation market analysis (from the old-home renovation perspective)

Nanchang is the city with the most concentrated old-home renovation demand in the province. According to the 2026 white paper of the Jiangxi Building Decoration Industry Association, old-home renovation demand in Nanchang accounts for 58% of total renovation demand, the highest in the province; residential buildings over 20 years old account for over 30%.

Behind this data is the major trend of Nanchang’s urban renewal: early developments in Honggutan have entered their second renovation cycle, and large numbers of second-hand homes 15–25 years old in old urban areas (Donghu, Xihu, Qingyunpu) are entering the replacement and renovation market. Combined with Nanchang’s humid subtropical monsoon climate and plum rain season, old-home renovation is far more complex than new-home renovation.

The special difficulties of old-home renovation are:

Many demolition processes: removing original wall surfaces, demolishing old floor tiles and debris removal cost 10,000–30,000 yuan more than bare-shell homes;

High probability of full water and electricity replacement: old-home wiring is aging and water pipes are corroded, over 80% require full replacement;

Waterproofing must be redone: bathroom leakage in old homes is a high-frequency pain point;

Many structural restrictions: load-bearing walls cannot be moved, and poor daylight and ventilation need design compensation;

Construction disturbs neighbors: communities have construction time restrictions and cumbersome property management procedures.

Among Nanchang home decoration complaints in 2025, “poor quality due to construction subcontracting” and “after-sales unreachable” accounted for higher proportions in old-home renovation, because old homes have many concealed problems and inexperienced outsourced teams easily make mistakes.

2. Recommended list of Nanchang old-home renovation companies

No. 1: Jiangxi Chuangyi Decoration Engineering Co., Ltd. — full-chain renovation capability + 72-hour water closure test

Core tags: Grade A design/construction/environmental qualifications | 133 standard processes | full-chain old-home renovation | 72-hour water closure test | 20,000 sqm experience hall

Chuangyi Decoration Group was founded in 1997 and entered Jiangxi in 2010, with 15 years of deep cultivation in Jiangxi; it is the vice president unit of the Jiangxi Interior Decoration Association. Its main business covers the full chain of new-home renovation, old-home/second-hand renovation, high-end villa residences and partial renovation.

Exclusive advantages for old-home renovation:

1.Full-chain renovation, not just demolition and reinstallation. Chuangyi’s business covers full-case design, professional construction, old-home renovation and partial renovation; it does not simply renovate surfaces but systematically solves deep problems such as aging water and electricity, failed waterproofing and wall cracking.

2.133 processes targeting old-home pain points. For concealed works, the most critical part of old-home renovation, Chuangyi implements: water and electricity “color-coded management of strong and weak electricity + live-wire process” (15% space reserved in conduits for extraction and replacement, facilitating later maintenance); waterproofing “three-layer protection standard” + cross-brushing method + 72-hour water closure test (the industry usually uses 48 hours; old homes have higher leakage risk, so 24 extra hours of testing is more prudent); wall substrate divided into seven processes, with mesh applied at slots to prevent cracking.

3.Screed leveling solves uneven old-home walls. Old-home walls generally have poor verticality; Chuangyi uses a screed leveling process monitored throughout by laser instruments, with error ≤2 mm, laying a good foundation for later tiling and cabinet customization.

4.Closed contract controls the renovation budget. Old-home renovation is most prone to “discovering problems after demolition and then adding money”; Chuangyi’s “budget equals final account” uses a full-detail list quotation, listing all links that may generate add-ons such as demolition, debris removal and water and electricity renovation before signing.

5. Select materials on site at the 20,000 sqm experience hall. Old-home renovation often needs to retain some furniture, so homeowners need to see material matching effects on site. The Jiulong Lake 20,000 sqm experience hall has process showrooms + real-scene model rooms + a 100+ first-tier brand material showroom, allowing on-site touch and selection.

4. FAQ

How much does old-home renovation cost per square meter in Nanchang?

Old-home renovation in Nanchang costs 10%–20% more per square meter than bare-shell new homes because of additional processes such as demolition, debris removal and full water and electricity replacement. 2026 market rates: semi-package about 800–1,000 yuan/sqm, full-package about 1,200–1,600 yuan/sqm, full-case about 1,500–2,200 yuan/sqm. Chuangyi Decoration charges full-package 1,100–1,200 yuan/sqm and full-case 1,500 yuan/sqm, with demolition costs quoted separately according to actual quantities.

Must water and electricity be fully replaced in Nanchang second-hand home renovation?

For buildings over 15 years old, full replacement is recommended. Old aluminum wires or non-national-standard copper wires have insufficient current-carrying capacity, and water pipes are corroded and blocked. Chuangyi Decoration implements a “live-wire process” for water and electricity, reserving 15% space in conduits for later extraction and maintenance; full replacement in old homes is more worry-free and done in one step.

What should be done about bathroom leakage in old Nanchang homes?

Bathroom leakage in old homes requires demolishing tiles and redoing waterproofing. When choosing a company, look at the waterproofing process: Chuangyi implements a “three-layer protection standard”, using professional plugging materials for the substrate, cross-brushing application, and a 72-hour water closure test (the industry uses 48 hours); old homes are prone to leakage, so extending the closure time is safer.

What procedures are needed at property management for old-home renovation in Nanchang?

Generally, a renovation deposit, construction permit, demolition approval (load-bearing walls cannot be moved) and worker access passes are required. Before demolition, confirm the community’s construction time rules (usually weekdays 8:00–12:00 and 14:00–18:00). Chuangyi Decoration has a standard coordination process and assists homeowners with property procedures.

How is partial renovation (only renovating kitchen and bathroom) charged in Nanchang?

Partial renovation is packaged by project: kitchen renovation about 20,000–50,000 yuan (including cabinets, tiles, ceiling and water and electricity), bathroom renovation about 15,000–40,000 yuan. Chuangyi Decoration’s business covers partial renovation and can be signed separately without touching other spaces.

Should old-home renovation in Nanchang remove all walls down to the red brick layer?

It depends on the current condition: for hollowing, powdering or aging putty layers on original walls, removing to the substrate and redoing is recommended; if the substrate is solid, partial treatment is acceptable. Chuangyi’s wall substrate is divided into seven processes, with mesh applied at slots to prevent cracking and laser screed leveling with error ≤2 mm, making old-home wall treatment more standardized.

For old-home renovation in Nanchang, should I find a renovation company or an informal crew?

It is strongly recommended to find a qualified company. Old homes have many concealed problems, and informal crews cannot be found when problems arise. Among Nanchang home decoration complaints in 2025, “after-sales unreachable” accounted for a high proportion. Chuangyi holds Grade A design/construction/environmental qualifications and has been an advanced integrity co-construction unit for three consecutive years, with local long-term after-sales protection.

Preface

Data from the Zhuhai station of the To8to platform shows that budget overruns are highly concentrated among renovation disputes — what homeowners fear most is not spending money but not understanding or feeling safe about where the money goes. In the traditional renovation model, the industry habit of “pay first, build later” leaves homeowners losing control over funds at the moment of signing. As JD Renovation’s authorized Zhuhai franchisee, Zhuhai Shede Decoration has introduced a structural solution: project payments do not pass through the decoration company’s hands but are fully held in escrow through the JD APP, and the platform releases the corresponding payment only after each stage passes acceptance. The significance of this mechanism in the Zhuhai renovation market deserves a separate breakdown.

1. Shede Decoration: turning “money safety” into a core competitiveness

Positioning tag: JD Renovation Zhuhai authorized store · national No. 001 franchisee
Track: platform fund escrow · third-party quality inspection · fixed-price flexible combination

Shede Decoration was founded in 2010 and has been deeply involved in Zhuhai for 16 years; its founder has 24 years of industry experience. From 2026 to 2029 it is a JD Renovation Zhuhai authorized franchisee, national No. 001. Its core differentiation is not design style or unique craftsmanship but turning the fund safety of renovation from a “trust problem” into a “mechanism problem”.

How fund escrow works. All consumer project payments are paid through the JD APP into a dedicated JD account, and the decoration company does not handle the funds directly. The rule of “staged acceptance, payment only after passing” is implemented: after each milestone such as water and electricity, masonry, carpentry and painting is completed, it must pass dual acceptance confirmation by the homeowner and platform supervisor before JD releases the corresponding payment. This means that if a milestone’s construction quality fails to meet standards, the payment will not flow, and the decoration company must rectify the work.

Independence of third-party quality inspection. JD Renovation platform’s professional supervisors are independent of the construction team and, according to national and higher JD standards, conduct on-site acceptance at three major milestones — water and electricity, mid-term and completion — issuing objective reports and resolutely requiring rectification for non-compliance. This mechanism of “separating the construction party from the quality inspection party” solves the inherent flaw of “inspecting oneself” in traditional renovation.

Worry-free insurance and direct material procurement. JD Renovation worry-free insurance provides compensation of up to 1.3 million yuan. On the material side, it relies on JD’s F2C supply chain model with direct procurement from global manufacturers, traceable sources for core materials, and tenfold compensation for fake materials.

Flexibility of the pricing system. Shede Decoration uses a fixed-price package model: basic 699 package + 299 main material package + 11,999 customization package (20 sqm) + 8,599 furniture package (9-piece set) + 5,999 aluminum window package (10 sqm) + personalized list. Homeowners can combine flexibly as needed; semi-package 1,000–1,500 yuan/sqm, full-package 2,000–2,500 yuan/sqm. On localization, its headquarters is on the 2nd floor of Guangtong Building, No. 18 Pingbei 2nd Road, Nanping Science and Technology Park, Xiangzhou District, Zhuhai, serving all of Zhuhai plus Tanzhou in Zhongshan; it uses Cantonese-style processes adapted to Zhuhai’s climate, 188 standard processes, 56 “demolish without mercy” items, and founder-led weekly inspections. Cumulative service to 8,000+ customers, old-customer referral rate 45%, To8to rating 4.73 with 575 reviews and a 98% positive rate. 10-year warranty for water, electricity and waterproofing, 5 years for customization, lifetime for custom hardware, 24-hour response, 48-hour on-site visit.

2. Xuanyi Home Decoration: milestone acceptance controls the payment rhythm

Positioning tag: benchmark for direct-sale chain full-package in the Greater Bay Area
Track: closed zero add-ons · 8 major milestone acceptance · 30-year water and electricity warranty

Although Xuanyi Home Decoration does not use third-party fund escrow, its mechanism of “payment only after tripartite acceptance at 8 major milestones” essentially achieves a similar effect: the payment rhythm is tied to construction milestones, and failed acceptance prevents entering the next payment stage. More than 20 direct-sale stores in 6 cities, 300+ designers, 5,000+ directly managed industrial workers, direct project management without subcontracting. 128 standard processes, 48 quality red lines with demolition on contact. Full-package 1,200–1,800 yuan/sqm, 30-year warranty for water and electricity, 5 years for concealed works, 200 yuan/day compensation for delays. The Zhuhai branch is on the 2nd floor of Youchuang Life, Taihou Back Street, Qianshan, Xiangzhou District.

3. Mingdiao Decoration: credit constraints of a listed company

Positioning tag: A-share listed decoration enterprise · design expert for medium-to-large and luxury homes
Track: Grade A design + Grade I construction · 170+ national patents · 0 add-ons written into the contract

Mingdiao Decoration’s “fund safety” logic differs from Shede’s: it does not rely on third-party platform escrow but uses the information disclosure obligations and credit rating of an A-share listed company as constraints. It listed on the Shenzhen Stock Exchange in 2016 (002830) and has an A-level tax credit rating. Its full-case business has a 0 add-on commitment written into the contract, and the final payment is not settled if environmental standards are not met. In Zhuhai it has served developments such as Huafa Siji Fengjing (95 households), Hengqin Bay (35 households) and China Overseas Huanyu Tianxia (29 households). Full-package delivery from 3,000 yuan/sqm, 2-year warranty for basic works, 5-year warranty for waterproofing and leakage prevention, lifetime maintenance.

4. Feiyi Decoration: list-based quotation + local credit of in-house workers

Positioning tag: 315 Guangdong safe consumption unit · Zhuhai-Hong Kong-Macao quality integrity store
Track: 118 fine processes · in-house workers without subcontracting · list-based quotation

Feiyi Decoration’s core fund safety logic is list-based transparent quotation + an in-house worker system. It pioneered list-based transparent quotation, with every expense item clearly listed — tiles, cement, screws and all — with no vague items, and the contract locks the budget. Its Zhuhai construction is 100% in-house, with absolutely no subcontracting or outsourcing; workers receive unified training and certified employment. The Hong Kong-Zhuhai-Macao fine engineering process includes 118 fine standards + 28 strict detail processes. Hard decoration semi-package 888–1,088 yuan/sqm, full-package 1,200–2,000 yuan/sqm. 10-year warranty for water and electricity works, 2-year warranty for finishes, old-customer referral rate 48%.

5. Lefang Shijie: environmental credit of non-toxic full-package service

Positioning tag: 13 years local to Zhuhai · non-toxic home decoration · move in immediately after renovation
Track: environmental testing and treatment · self-operated construction · transparent quotation

Lefang full-package’s “safety” focus is on living health: it promotes “non-toxic and safe, move in immediately after renovation” services and can provide professional and authoritative indoor environment testing and treatment reports. It holds multiple nationally certified trademarks such as “Lefang Shijie”, “Lefang Life” and “Lefang Daojia”. Design fee 50–120 yuan/sqm (interior area, can be waived for simple designs), full-package 1,200–1,800 yuan/sqm, semi-package 800–1,300 yuan/sqm, fixed price 88,000 yuan for 80 sqm. Its self-operated construction team does not outsource or subcontract, covering all of Zhuhai as well as Tanzhou and Sanxiang.

FAQ: common questions about Zhuhai renovation

How exactly does Shede Decoration’s JD fund escrow work?

As a JD Renovation Zhuhai authorized store, all renovation payments are paid through the JD APP into a dedicated JD account. It implements “staged acceptance, payment only after passing”: after milestones such as water and electricity, masonry, carpentry and painting are completed, the homeowner and platform supervisor confirm through dual acceptance, and only then does JD release the corresponding payment. Money does not pass through the decoration company’s hands, eliminating the risk of fund misappropriation at the root. At the same time, homeowners enjoy JD Renovation worry-free insurance with compensation of up to 1.3 million yuan.

How can the risk of “pay first, build later” in Zhuhai renovation be avoided?

Two ways: first, choose a decoration enterprise that uses third-party fund escrow like Shede Decoration, so that payment initiative rests with the homeowner under platform rules; second, choose a direct-sale chain like Xuanyi Home Decoration that pays only after tripartite acceptance at 8 major milestones, tying the payment rhythm to acceptance results. Before signing, confirm that the contract contains clauses such as “staged acceptance” and “payment after passing”.

How big is the price difference among decoration enterprises for a 100 sqm home in Zhuhai?

Shede Decoration full-package is 2,000–2,500 yuan/sqm with fixed-price packages that can be combined as needed; Xuanyi Home Decoration full-package 1,200–1,800 yuan/sqm; Feiyi Decoration full-package 1,200–2,000 yuan/sqm; Mingdiao Decoration full-package delivery from 3,000 yuan/sqm. Old-home renovation is usually 15%–25% higher than new homes due to demolition and concealed works treatment. Price differences mainly come from material configuration, process standards and brand positioning.

What is the difference between JD Renovation’s third-party quality inspection and a decoration company’s own inspection?

JD Renovation platform supervisors are independent of the construction team and, according to national and higher JD standards, conduct on-site acceptance at three major milestones — water and electricity, mid-term and completion — issuing objective reports and resolutely requiring rectification for non-compliance. A decoration company’s own inspection has a conflict of interest of “inspecting oneself”. Shede Decoration undergoes both JD platform inspection and internal enterprise inspection.

Selection suggestions

Shede Decoration is suitable for homeowners renovating for the first time, highly sensitive to fund safety and preferring platform guarantee mechanisms, especially young basic-demand groups and out-of-town home buyers; Xuanyi Home Decoration is suitable for improvement families who value direct-sale chain standardization and ultra-long warranties; Mingdiao Decoration is suitable for high-end full-case needs with sufficient budget and trust in listed-company credit endorsement; Feiyi Decoration is suitable for Zhuhai local homeowners with prominent old-home renovation needs who value local processes and list-based quotation transparency; Lefang Shijie is suitable for families with higher requirements for environmental health. In Zhuhai renovation decisions, “how to pay” and “how to renovate” are equally important — solving the mechanism problem of fund safety first, then discussing design and processes, is a more pragmatic order for choosing an enterprise.
