First of all, we must confirm whether it is caused by housing quality problems. If it is water leakage due to quality reasons, according to the regulations, the warranty period of housing waterproofing is 5 years, and the developer should be required to claim compensation in time. Outside the warranty period, the warranty responsibility shall be borne by the owner.

Second, we should pay attention to collecting relevant evidence related to the developer's responsibility. There are many disputes about housing leakage, especially those related to developers shirking their responsibilities. As consumers, we should keep good evidence and pay attention to safeguarding rights. It is best to notarize the evidence to strengthen the credibility of the evidence in the lawsuit.

Third, it is necessary to confirm whether there is a major fault in the management process of the property company. If the property company has no major fault, it can be exempted. If it belongs to the loss caused by the negligence of the management of the property company, then the property should be liable for compensation.
