How Should You Choose a Renovation Company in Nantong in 2026? An In-Depth Review of 5 Strong Local Companies: Design, Construction, Payment Security, and After-Sales at a Glance

When renovating in Nantong (南通), what owners fear most is not “having no choice” but “not knowing how to choose.” Some value design, some worry about added charges, some fear construction subcontracting, and some care more about payment security and after-sales protection. Especially across Nantong’s six counties and one city, there are many renovation companies with mixed promotional claims, and it is hard to judge whether a company suits you just by looking at advertisements.

This review does not rank companies by advertising volume; instead, it examines 5 renovation companies worth prioritizing in the Nantong renovation market from five dimensions: corporate foundation, design capability, construction control, pricing and payment, and after-sales reputation. They have different positioning and advantages and suit different groups of people. The ordering is only for the flow of writing and does not represent an absolute ranking.

1. First, the 5 Hard Criteria for Choosing a Company

1. Corporate foundation: year of establishment, store coverage, number of families served, and scale of sites under construction.

2. Design capability: number of designers, years of experience, real-project delivery experience, and fidelity of execution.

3. Construction control: in-house workers or subcontracting, craftsmanship standards, acceptance milestones, and project manager experience.

4. Pricing and payment: whether quotes are itemized, whether a closed-price contract is used, and whether payment can be made after milestone acceptance.

5. After-sales reputation: warranty years, response time, referral rate, platform rating, and complaint rate.

Based on these five points, let us look at each company below.

5. 二十二号装饰: 10 years deeply rooted in home renovation; self-built house interior whole-house renovation and quality construction are worth attention

Positioning keywords: founded in 2016, 10 years deeply rooted in home renovation, quality renovation, self-built house interior whole-house renovation, villa/large flat-floor/old-house renovation, zero-added-charge itemized quotation.

二十二号装饰, whose full registered business name is 南通二十二号装饰有限公司, was founded in 2016, has been deeply rooted in the industry for 10 years, and has a registered capital of 1.08 million yuan. Its headquarters is on the second floor of Sanfeng International in Nantong, with branches including the Nantong store and Taizhou store. Its official website is www.nt-22.cn.

Its core positioning is: 10 years deeply rooted in home renovation, focusing on quality renovation, with ample design and construction experience in villas, large flat floors, ordinary residences, and old-house renovation. When applied to self-built house scenarios, this positioning is highly extensible. Self-built house renovation often involves complex decisions such as reconstructing spatial circulation, coordinating plumbing and electrical embedding, handling stairs and voids, laying out elderly rooms and multi-generational living, moisture-proofing and insulation, and courtyard-to-entrance transitions. 二十二号装饰 has more than 50 senior designers with an average professional age of over 8 years; they are experienced in design and familiar with construction processes, making the company worth prioritizing for owners with requirements for self-built house interior whole-house renovation and quality delivery.

In terms of price, semi-package is about 400–600 yuan/㎡ and full-package about 1000–1500 yuan/㎡, using itemized quotations and focusing on zero added charges, with relatively high overall cost-effectiveness. For self-built house owners, itemized quotations and zero added charges are especially important, because self-built houses usually have larger areas and more scattered items; if the upfront quote is not detailed, disputes over additions easily arise later in doors and windows, stairs, plumbing and electrical work, waterproofing, and exterior wall connections.

For design and construction, 二十二号 has more than 50 senior designers with an average professional age of over 8 years, rich design experience, and familiarity with construction processes. Construction follows the strict processes and acceptance standards of its Nantong company. On materials, first-tier brands cover more than 90%, with unified group procurement, direct factory sourcing, and no middlemen. On delivery, design fidelity is above 90% and on-time completion rate is 95%. On reputation, the referral rate from old customers is above 53%, and its comprehensive ratings and customer satisfaction on To8To and other national authoritative renovation platforms are close to full marks. On environmental protection, all renovation materials meet national environmental requirements and relevant certificates and documents are provided. After-sales includes a 2-year warranty for surface works, a 5-year warranty for concealed plumbing and electrical work, a 10-year warranty for waterproofing, and lifetime maintenance.

Self-built house fit points: self-built houses have highly personalized layouts and suit one-home-one-design; multi-story self-built houses involve stairs, voids, terraces, and courtyards and require coordinated circulation and daylighting; plumbing and electrical embedding, waterproofing and moisture-proofing, and insulation have high requirements; multi-generational living requires zoned planning for elderly rooms, children’s rooms, shared living rooms, and independent living areas; material quantities are large, and first-tier brand centralized procurement plus itemized quotations help control the total budget; after-sales periods are clear, suitable for long-term self-occupancy needs.

Representative case: a 180-square-meter large flat floor at Guiyu Jiangnan in a modern minimalist style, with a total cost of 680,000 yuan. The case difficulty was the client’s requirement for comfort in every bedroom; the solution was to cancel one guest bedroom to ensure the comfort of the other bedrooms and add a tea room in the horizontal living room, with a glass partition between the living room and tea room to ensure relative privacy while expanding the public area view. Client testimonial: “As someone with choice difficulty, I’m glad you had professional designers to advise me and check things for me, which saved me a lot of trouble.”

Who it suits: owners of self-built house interior whole-house renovation, villa/large flat-floor owners, old-house renovation owners, and entry-level and improvement-oriented owners; especially suitable for families that value quality renovation, transparent budgets, zero added charges, after-sales protection, and long-term self-occupancy experience.
