1, usually look for the property department first. The property department is generally entrusted by the developer to contact the maintenance affairs, and the property department (entrusted by the developer) contacts the construction unit for warranty.

2, such as housing maintenance funds have been deposited, which belongs to the purchased public houses directly under the municipal government, and the owners shall apply to the owners' committee or neighborhood committee; Put forward the housing maintenance fund. The part of the house maintenance cost that exceeds the deposit of the maintenance fund shall be shared by the relevant owners according to the proportion of the house construction area.

3. If the purchased unit manages public houses by itself, the owner shall apply to the owners' committee or neighborhood committee where the house is located; After the owners' committee or neighborhood committee puts forward the details of the housing maintenance budget, consult the owners and fill out the application form, and send it to the original selling unit; After the original unit sells the house to the maintenance fund and deposits it in the bank for reconciliation and fills in the relevant forms, it shall go through the procedures of extraction and review with the data to the city housing security center; After approval, the original selling unit will remit money to the bank and transfer it to the account designated by the owners' committee or neighborhood committee for the actual maintenance of the house.

4. Leakage of commercial housing: If the owner's house is still under warranty, the developer should be required to be responsible for the warranty.

If water leaks upstairs, causing losses to the parties, as long as the parties can prove that the losses are caused by the upstairs residents (fault liability), they can claim compensation from them.

What are the general situations of water leakage in houses?

1, pipeline leakage: a phenomenon of house leakage is pipeline leakage. The pipeline is not firmly fixed during installation, which may cause looseness; There is an error in the position of the reserved port of the pipeline, and the concrete pouring is not in place; Failure to do a good job of leakage prevention is the reason why the pipeline is easy to leak. In this case, we have to dig pipes for waterproof treatment to solve this problem fundamentally.

2. Waterproof layer leaks: Sometimes even if we all make waterproof layers, it will still leak. This situation is generally caused by man-made construction damage, which will also lead to water leakage in the waterproof layer; Damage caused by pipeline installation and damage caused by construction of protective layer or waterproof layer; At this time, it may be that the waterproof material itself has quality problems. At this time, it is necessary to shovel off the waterproof layer and waterproof it again. After completion, it is necessary to do a penetration test. If there is no problem, it means it is fixed.

3. Black spots on the wall and floor: This kind of situation often appears in our life. In our life, we will find that there will be black spots on the walls when they are wet, or there will be water leakage on the top and walls, especially when they are wet or even moldy and hairy in winter. This phenomenon not only affects the appearance, but also brings a lot of inconvenience to our life. These may be that the construction personnel did not follow the construction requirements and specifications, or the concrete was not vibrated and compacted sufficiently when pouring the floor slab, which may easily lead to some quality problems such as hollowing, honeycomb and pits, or the quality problems of cement and concrete itself. So once you find water leakage, you must find the water leakage point at this time. After finding the leakage point, you can shovel off the protective layer of the leakage point on the wall or ground. Then repair it according to the specifications, so that it can be waterproof again and then restored.
