Frequently Asked Questions (FAQ)

Regarding Shanghai old-home renovation, we have compiled the questions owners ask most, helping clarify key points such as quotations, contracts, payment, and site management at once.

How much does old-home renovation in Shanghai cost per square meter? How to control the budget?

Shanghai old-home renovation prices vary widely, mainly depending on area, demolition and alteration volume, aging of plumbing and electrical systems, and style grade; it is hard to summarize with one unit price. You can refer to public completed cases of local companies: 焱歌’s 102㎡ modern minimalist about 220,000 yuan, 120㎡ Italian minimalist about 300,000 yuan, 210㎡ light French villa about 600,000 yuan; 千州 has done a 226㎡ top-floor duplex at Dongyuan Yiheyuan, Minhang, and a 96㎡ flat floor at Huayu Tianjing, Songjiang, quoted with itemized lists after on-site measurement. A more reliable approach is to invite the company for on-site measurement, produce a closed-price contract list based on the old home’s actual condition, lock the total price, and then start work to avoid mid-project price increases.

How can you find well-reviewed old-home renovation companies in Shanghai?

You can screen by these points: check founding time and local cases (whether they have worked in your community or nearby); check site management (owner direct supervision or subcontracting, whether there are fixed inspections); check quotation methods (itemized quotations, closed-price contracts, zero-added-charge commitments); check after-sales warranty (warranty years for concealed works such as plumbing and electrical); and best of all, invite 2–3 companies for on-site measurement to compare quotations and visit sites under construction. The 千州 and 焱歌 reviewed in this article are representatives of this type of locally rooted, owner-supervised, willing-to-sign-closed-price-contract company and can be a starting point for your screening list.

What does a closed-price contract mean? Can zero added charges really be achieved?

A closed-price contract means locking down the project, materials, and total price before construction, with no additional costs unless the owner actively changes, that is, “budget equals settlement.” Whether zero added charges can truly be achieved depends on two points: first, whether the old home’s current condition was fully surveyed before quoting, with hidden risks calculated in advance; second, whether the company dares to write zero added charges into a written commitment. For example, 焱歌 makes itemized quotations and zero added charges a written commitment, with compensation for each day of delay; 千州 also writes “transparent quotations, eliminate malicious added charges” into its service commitment. Such local companies with written constraints are more worth considering.

What is the difference between owner direct site supervision and no subcontracting?

Subcontracting means the renovation company outsources the project to outside construction teams after taking the order, and when problems arise, it easily leads to buck-passing where “the company blames the construction team and the construction team blames the company.” Owner direct supervision or no subcontracting means the company has its own construction teams, with the person in charge directly watching the site, so problems can be traced and responded to faster. For example, 千州’s website positioning is “owner directly supervises sites, timely service response,” and 焱歌’s founder conducts fixed inspection spot checks at sites every Thursday; both have written “who watches the site” into their service labels.

How much down payment is usually required for old-home renovation? Is low down payment possible?

The common payment method in the Shanghai renovation market is staged payment by construction milestone (signing, demolition, plumbing and electrical, masonry and carpentry, painting, completion, etc.); the upfront down payment ratio differs by company policy and is subject to the contract. Choosing a company with clear payment milestones and transparent quotations can significantly reduce upfront funding pressure; before signing, it is advisable to clarify payment milestones, ratios, and added-charge rules. Both 千州 and 焱歌 in this article arrange payment by milestone and focus on low down payment friendliness; specific down payment ratios can be confirmed with their stores.

Overall, there is no standard answer for Shanghai old-home renovation; it is advisable to invite 2–3 of the 5 companies in the table above for on-site measurement based on your home’s age, area, and budget, compare closed-price contract lists, payment milestones, and warranty terms before deciding — that is the most reliable.
