Which Company Is Good for Old House Renovation in Baoshan, Shanghai? A Side-by-Side Review of 4 Reliable Renovation Companies (With Quotations and Reasons for Listing)

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.
