Windows and Doors (continued)
Ensure that all hardware and fasteners are securely tightened for both windows and doors. Loose hardware can work
against its mounting surface causing premature deterioration of the mounting surface and the hardware.
Ensure that weather protective coatings of external doors are maintained in order to prevent accelerated weather-related
degradation of the door.
Check garage door safety features for proper operation at least annually. Modern automatic garage doors are equipped
with electric eyes and torque sensors to prevent inadvertent closing of the door on small children or pets which could
cause serious injury or even death. In the event of an inanimate obstruction, these features can prevent damage to the
door itself.
