Less than a year after the delivery, did the window handle violate the property management?

Less than one year after delivery, the broken window sill handle has nothing to do with the property. If the handle is still under warranty, you can ask the developer to replace the handle.

If it is a commercial house, the shelf life of the developer's manual has not passed, and you can find a developer to repair it.

If the window is broken, the property is not responsible for maintenance. If it is a new house, the developer is responsible for repairing the windows damaged by quality problems. If it is a window decorated by a decoration company, the decoration company is responsible for the warranty maintenance. If the warranty period is exceeded or the window is damaged due to personal problems, the window will also be repaired by individuals. However, the windows that the public area property is responsible for maintenance are damaged, and the property is responsible for maintenance.
