The roof of the newly bought commercial house is leaking. What department should I complain to?

1. The newly bought house is leaking, so you should usually look for 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 you only have a contract and warranty relationship with the developer, you can directly find the developer (or find the representative of the property department or construction unit entrusted by the developer).

3。 You are protected by the terms of the contract and the consumer rights law. You can complain when the property department and the developer don't care. Complaints should be made to the local "Construction Engineering Quality Supervision Station" or the local "Consumers Association".

4。 At the end of the warranty period, you can find the property department for maintenance. If it's not for you, you don't have to pay it (from the housing maintenance fund, the buyer and the developer have already paid it).

5。 Repair method: chisel out the leakage part of the external wall from the outside and fill it with cement mortar with cement content of 1: 2 and 15% alunite expansion agent.
