Who is responsible for the leakage of the external wall window?

Legal analysis: It depends. Usually upstairs is responsible for maintenance. If the house is still under warranty, you can ask the developer to repair it.

1, the newly bought house is leaking, please consult the property department first. Because the property department is generally entrusted by the developer to contact the maintenance affairs, the property department (entrusted by the developer) should contact the construction unit for warranty. The developer has a contract with the construction unit, and the developer has the warranty of the construction unit, so as long as it is not the cause of abnormal use, the construction unit must guarantee the "house leakage".

2. Because the owner and the developer have a contract and warranty relationship, the owner can also directly find the developer (or find the representative of the property department or the construction unit entrusted by the developer).

3. The house is protected by contract terms and consumer rights law. When the property department and the developer ignore it, the owner can complain, and the complaint should be made to the local "construction engineering quality supervision station" or the local "consumer association".

4. At the end of the warranty period, you can find the property department for maintenance.
