In May 2003, my family moved into a new house, and soon found that the wall of the innermost house of my family began to fall off. We started property negotiation, but the property kept asking.

1. warranty period. According to your description, this is an engineering quality accident, which mainly involves the warranty period of the project. The infilled wall belongs to the main structure division. According to the provisions of the Building Law, the warranty period of the main structure project is the service life of the house.

2. Compensation for losses. For the problems that have not been solved by the property management company since 2003, you can request legal aid and provide relevant evidence since 2003 to negotiate with the property.
