The top floor wall and ceiling are leaking, how to solve it completely?

Thoroughly solve the top leakage method is as follows:

1. Find a developer for maintenance during the warranty period: If the purchased commercial house is still under warranty, you can find a developer for free maintenance if the roof leaks. The warranty period of roof waterproof layer is 5 years. As long as it is within the warranty period, developers are responsible for maintenance. However, if the warranty period of the house is approaching, we must urge the developers to deal with this situation as soon as possible to avoid the delay of the house beyond the warranty period, and the final maintenance costs must be borne by themselves.

2. Check the leakage area: If the house has passed the shelf life, then the owner needs to deal with the leakage problem himself. Therefore, the first step is to check the leaking place at home and see how big the leaking place is. If it is a small crack, it can be sealed directly with cement. Brush a layer of cement ash on it after caulking. If the leakage area is relatively large, then cement may not be suitable, and other methods should be chosen at this time.

3, asphalt treatment: generally speaking, water leakage is not particularly serious, in addition to cement, you can also choose asphalt for treatment. When working, the leaking part of the roof should be removed about 3 cm first, and then sealed with asphalt after cleaning. Generally speaking, this method is relatively simple and inexpensive. Because of the small leakage area, this method can still be chosen.

4. Re-make waterproof layer: We also said that cement asphalt can only repair small cracks. If the roof leaks seriously, it means that the waterproof layer has been destroyed, and cement and asphalt can no longer play their roles. In this case, the waterproof layer can only be re-made, which can fundamentally solve the problem. If the roof waterproof layer is found to be damaged or bulging, it means that the waterproof layer cannot be repaired and needs to be replaced in time.
