How many years can the bathroom be warranted for waterproofing?

Do a good job of waterproofing and test the water so that it does not leak. But now it's basically from the day the contract is signed. Bathroom waterproofing is generally warranted for five years. At least three years of warranty.

The answer depends on how many years of warranty you have signed the contract with the decoration company, and the general company has a warranty of 1-2 years. You look for the contract, the warranty period is not the responsibility of the developer, do not deal with the local quality supervision department to complain, they are in charge of this matter, and then do not go to court to sue, otherwise the warranty period is self-care.

It should be re-inspected for more than 3 months, and scrapped for more than half a year.

Article 40 of the Regulations of the State Council on the Quality Management of Construction Projects stipulates that: "Under normal use conditions, the minimum warranty period of a construction project is: (1) The reasonable service life of the project specified in the design documents for infrastructure projects, foundation works and main structure works of housing construction; (2) Leakage prevention of roof waterproofing projects, toilets, rooms and external walls with waterproof requirements for 5 years; (3) Heating and cooling system, which is two heating periods and cooling periods; (4) Installation and decoration of electrical pipelines, water supply and drainage pipelines, and equipment shall be 2 years.

The warranty period for other items shall be agreed between the employer and the contractor. The warranty period of the construction project shall be calculated from the date of acceptance of the completion of the project. ”
