As for the places that the other party says need to be repaired, you can repair them. After the repair, the other party will pay the warranty money after the warranty expires.
If you don't repair it, the other party can repair it by itself and deduct the corresponding quality deposit from you.
Extended data:
Function:
The project warranty fund refers to the funds agreed by the construction unit (owner) and the construction enterprise in the project construction contract to perform the project maintenance responsibility during the defect liability period and set aside from the project payment payable to ensure that the construction enterprise can repair the project defects that have passed the completion (handover) acceptance during the defect liability period.
The project quality deposit shall be directly deducted from the project measurement appropriation of the construction enterprise by the construction unit (owner) according to the total settlement amount of the project price multiplied by the proportion agreed in the contract (generally 3%), and interest shall not be calculated generally. The construction enterprise shall be in the defect liability period (generally twelve months) after the project is completed (handed over).
Earnestly fulfill the responsibilities agreed in the contract, and apply to the construction unit (owner) for returning the project quality deposit in time after the expiration of the defect liability period. The construction unit (owner) shall promptly return the project quality deposit to the construction enterprise (if there is any defect during the defect liability period, the corresponding defect maintenance fee shall be deducted).
