Is it the responsibility of the property to automatically drop the window at home?

I lost my own things, it must be my own business.

If the house is under warranty, you should find a property management company. Many property companies are responsible for coordinating maintenance during the warranty period, and they will contact developers and construction units.

The property management company is responsible for the maintenance of the * * * use area and the * * * use facilities and equipment, and its own windows should not be covered by property management services.

Look at the warranty clause of the home housing contract. If the real estate license has been changed, ask the development company. Check the service agreement you signed with the property management company to see if there is any agreement. If there is an agreement, it shall be implemented according to the agreement.

Or consult the local property authorities to reflect your family's situation.
