I bought a new Nianhua house in Shui Mu, Yubei District, and found that there were quality problems in the decoration, regardless of the property management. I should find the relevant department to handle it. Please help me. Waterproof warranty for 5 years and pipeline for 2 years. During the warranty period, the developer is not responsible. If not handled, you can complain to the local quality supervision department. They specialize in this matter, and then you can't go to court, or you will be responsible for delaying the warranty period! In addition, if the same place is not repaired twice during the warranty period, you can find someone to repair it yourself, and the cost will be borne by the developer. What year did you buy your house?
