No matter what happens when the ceiling of a residential building leaks.

Just make sure the responsibilities are clear. I'll analyze it for you according to what you said.

1. The decoration upstairs caused your ceiling to leak. The responsibility lies on the second floor, which infringes on your rights and interests.

2. The house has little to do with the warranty period, and the developer is no longer responsible for the water leakage caused by the decoration (the original waterproof is destroyed).

3. Property reply You are talking about the problems on the 7th and 8th floors. You have to find out what the reasons are for the problems in the property, the seventh floor and the eighth floor, and then you will know the responsibility and who should bear it.

4. The property plays a coordinating role, and there is no certain maintenance obligation (unlike the previous one, exposure or pressure can solve the problem).

I suggest that you first ask the property management to help coordinate, find out the cause and location of the water leakage, and find out who is responsible; After finding the responsible person, it can be solved through the coordination of the property, neighborhood committees, industry committees, street offices, mediation centers and other departments; If the coordination fails, directly sue the responsible person (infringer), demand to stop the infringement, compensate the losses and bear the legal costs.
