What is the basis for the property to require unified window sealing?

There is no basis. According to the "Property Management Regulations", the inquiry shows that the property company has no right to require the owner to seal the windows, but it can uniformly require the color, opening mode, glass color and performance indicators of doors and windows. The realty service enterprise shall stop the violation of laws and regulations such as public security, environmental protection, property decoration and use in the realty management area, and report to the relevant administrative departments in a timely manner. After receiving the report from the realty service enterprise, the relevant administrative department shall stop the illegal act or deal with it according to law.
