Hello, my answer to this question is as follows. When there is a problem of water leakage in the house, most owners are the first to find the property, but many properties refuse that this is a problem of the developers. It has nothing to do with themselves, and they can only be responsible for coordination. What should we do at this time? At the time of delivery, there will be "Residential Quality Guarantee". The state has stipulated the minimum warranty content and duration for some contents, specifically: roof waterproof for 3 years; Leakage of walls, kitchen and toilet floors, basements and pipes for 1 year; Wall and ceiling plastering layers fall off for 1 year; Doors and windows are warped and cracked, and hardware parts are damaged for 1 year; The ground is hollowed and cracked, and large area sanding occurs for 1 year; The pipeline is blocked for 2 months; One heating or cooling period for heating and cooling systems and equipment; Sanitary ware 1 year; 6 months for lamps and electrical switches. The warranty period starts from the date when the developer delivers the house to the buyer. When handling house delivery and acceptance, the buyer must sign to confirm the normal use of house facilities and equipment. As long as the house is within the warranty period, you can negotiate with the developer to ask them to repair or even compensate for the loss. If the developer refuses to perform, and both parties fail to reach an agreement on the repair, they can first repair by themselves, and the developer will claim compensation for the loss after the repair is completed. Article 40 of the Regulations of the People's Republic of China on the Quality Management of Construction Projects: 5 years for roof waterproofing works, toilets, rooms and exterior walls with waterproofing requirements.
