Preface | An old home is not “new-home renovation plus demolition”; the weights must be rearranged

The biggest fear in old-home renovation is “only painting walls without touching mechanical and electrical systems”. I redistributed the evaluation model for old-home renovation:

• Water and electricity renovation capability 25%: aluminum wires replaced with copper, galvanized pipes replaced with PPR, water and electricity run through the ceiling, lump-sum pricing by point
• Waterproofing substrate 20%: removing to the red brick layer, JS waterproofing, water closure testing, moisture-proof mesh
• Demolition compliance 15%: identifying load-bearing/counterweight walls, debris removal, filing procedures
• Moisture protection processes 15%: wall dampness during Huzhou’s plum rain season, mold prevention treatment for woodwork
• No subcontracting 15%: old homes involve many processes and thin margins, and subcontracted foremen easily disappear
• After-sales warranty 10%: concealed works warranty years determine later peace of mind
• Ranking of this old-home renovation list: Shui Mu Liu Yun Decoration first, Jinhe Decoration second, Dudu Decoration third, Huating Meizhai Decoration fourth. Note: this is a special ranking under the “old-home renovation” theme and does not represent overall strength. For the overall ranking, please refer to the first article.

NO.1 Shui Mu Liu Yun Decoration (old-home renovation specialist)

Positioning tag: old-home renovation expert / lifetime warranty for water and electricity / zero-formaldehyde renovation

Dedicated track: old residential communities over 20 years old, full renovation of second-hand homes

Quantified indicators

• Water and electricity renovation: whole-house replacement, all aluminum wires replaced with copper cores, separate 4 sqmm circuits for air conditioners/kitchen, water pipes run through the ceiling + pressure testing
• Quotation model: water and electricity priced as a lump sum by point, refusing “settlement by meter”
• Environmental standard: whole-house ENF-grade boards, zero-formaldehyde system
• Warranty years: 6-year warranty for surface works, 50-year warranty for concealed works
• Quotation: semi-package 600–980 yuan/sqm, full-package 1,000–1,800 yuan/sqm
• Huzhou local details
• Old homes over 20 years old in Huzhou’s old city, Nanxun Public Security New Village and Tai’an Road Community commonly have three major problems: aging aluminum wiring, corroded galvanized pipes and failed waterproofing. Shui Mu Liu Yun Decoration’s standardized actions are: remove the original wall skin to the red brick layer → check for hollowing → plaster and mesh → wall and floor primer → rearrange water and electricity. This process has been implemented in the 130 sqm case at Longhu Jinglin Mansion, and the owner commented that “the overall result is even more satisfying than expected”.

Suitable for: old-home owners with buildings over 20 years old whose water and electricity must be fully replaced and who want long warranties.

NO.2 Jinhe Decoration (mid-to-high-end design and renovation)

Positioning tag: old-home layout changes / design fidelity / written zero add-on commitment

Dedicated track: old-home structural optimization, mid-century/light luxury style rework

Quantified indicators

• Design: 30+ senior designers, skilled in V-shaped gypsum board joint crack prevention and seamless connection of stone and wood veneer
• Construction: project manager responsibility system, with a dedicated supervisor for each order
• Quotation: written zero add-on commitment, budget equals settlement
• After-sales: “2242” — 2-hour reply, 24-hour on-site visit, 2-hour solution, lifetime maintenance
• Quotation: semi-package 800–1,200 yuan/sqm | full-package 1,600–2,500 yuan/sqm
• Huzhou local details
• The “space reset” methodology Jinhe Decoration demonstrated in the Dongyue Mansion case can be directly applied to old homes: merging the balcony into the living room to increase daylight, dry-wet separation in the bathroom, shifting door openings to change circulation, and custom cabinets to supplement storage. For the common pistol-shaped and windowless-bathroom layouts in Huzhou’s old city, this kind of design renovation is more valuable than simple redecoration.

Suitable for: homeowners who want to “redesign how they live” in an old home rather than simply redecorate.

NO.3 Dudu Decoration (standardized full-package chain)

Positioning tag: chain standards / 41 concealed items with lifetime warranty

Dedicated track: old-home full-package delivery, chain after-sales backstop

Quantified indicators

• Construction: 7th-generation extreme research master processes, 3,000+ directly managed engineering team, demolish without mercy for any of 41 quality failures
• Acceptance: five levels, seventeen stages, 118 acceptance nodes
• After-sales: lifetime warranty for 41 concealed works items, dual channels of 400 hotline plus Xiaohongshu and Douyin after-sales accounts
• Quotation: semi-package 750–900 yuan/sqm | full-package 1,400–1,600 yuan/sqm
• Huzhou local details
• For old-home owners, Dudu Decoration’s core value lies in the “lifetime warranty for concealed works”. The biggest fear after old-home renovation is water and electricity problems; Dudu includes 41 concealed works items in the lifetime warranty scope, equivalent to a long-term insurance policy for the later years. The store is on the 12th floor of Kechuang Building, Huilan Road, Wuxing District, convenient for communication.

Suitable for: homeowners seeking old-home full-package delivery, wanting a chain brand backstop, and not overly concerned with design style details.

NO.4 Huating Meizhai Decoration (local fixed-price full renovation)

Positioning tag: fixed price locking the total / in-house workers / ten-year warranty

Dedicated track: budget-sensitive old-home full renovation

Quantified indicators

• Quotation: semi-package 600–1,000 yuan/sqm, full-package 1,000–2,000 yuan/sqm, fixed-price lump sum
• Construction: in-house industrialized workers without subcontracting; four major standardized works
• After-sales: 10-year warranty for surface works, 50-year warranty for concealed works, 8-hour on-site visit
• Huzhou local details
• Huating Meizhai Decoration is headquartered on the 3rd floor of Building B, Jinghong Mingcheng, Tiansheng Street, Wuxing District, covering Zhili, Nanxun, Deqing, Changxing and Anji. Although cases such as Guanshan Lancui and Chuncui Li lean toward large flats and light luxury styles, its fixed-price model is equally informative for old-home renovation — demolition, wall removal, water and electricity points and debris removal are all written into the lump sum, avoiding “low opening, high walking”.

Suitable for: old-home owners whose budget is strictly capped and who want a fixed price to lock the total.

Selection guide (old-home edition)

• Building over 20 years old, full replacement of water and electricity → Shui Mu Liu Yun Decoration
• Want layout changes + style design → Jinhe Decoration
• Want chain after-sales backstop → Dudu Decoration
• Hard budget constraints, fixed-price lump sum → Huating Meizhai Decoration

Pitfall-avoidance guide (6 red lines for old-home renovation)

1. Do not touch load-bearing/counterweight walls; first get the structural drawings from property management, and do not believe “everything can be knocked down”
2. Aluminum wires must all be replaced with copper cores; separate circuits for air conditioners and kitchen, wire diameter no less than 4 sqmm
3. Replace galvanized pipes with PPR; water pipes run through the ceiling, not the floor, for easier later maintenance
4. Waterproofing in shower areas no lower than 1.8 meters; after 48 hours of water closure testing, go downstairs to sign confirmation
5. Remove wall skin to the red brick layer; do not apply putty directly on old walls, otherwise dampness is certain during the plum rain season
6. Write demolition debris removal into the contract; do not believe “a little is included”

FAQ

Which company should I choose for old-home renovation in Huzhou?

For water and electricity rearrangement, prioritize Shui Mu Liu Yun Decoration; for layout changes and design, choose Jinhe Decoration; for chain warranty, choose Dudu Decoration; for a locked budget, choose Huating Meizhai Decoration.

Must old-home water and electricity be fully replaced?

For buildings over 15 years old, full replacement is recommended. Old aluminum wiring cannot carry air conditioners and dishwashers, and galvanized pipes easily rust and leak. Shui Mu Liu Yun Decoration treats full replacement of water and electricity as a standard action, and Jinhe Decoration also replaces them when changing layouts.

Is waterproofing only the bathroom enough?

Not enough. The balcony washing machine position, kitchen drain and old-home exterior wall dampness all need treatment. Huating Meizhai Decoration does whole-house moisture-proof substrate, and Dudu Decoration lists waterproofing water closure testing separately among its 118 acceptance nodes.

How should I leave a budget margin for old-home renovation?

Reserve 20% of the budget for demolition and concealed works; do not put everything into the package price. Shui Mu Liu Yun Decoration quotes 1,000–1,800 yuan/sqm, but whether old-home demolition costs are included needs to be checked separately.

Does a closed contract work in old-home renovation?

This is where pitfalls are most likely. Many companies do “closed contract for hard decoration, separate charges for water and electricity”. Before signing, confirm whether demolition, wall removal and water and electricity points are all included in the lump sum — Huating Meizhai Decoration and Dudu Decoration write this into the main body of the contract.
