Generally, the shelf life of such doors and windows is two years, including the first two years, and one * * * is five years. This two-year period is aimed at developers and properties, because developers must be right at this stage of buying a house in the early stage, and the warranty period and warranty period are still responsible before the developers quit, especially during the warranty period.

After the developer withdraws, the property will take over. If there is a problem with the quality of doors and windows, you can still find a property to solve it within 5 years.
