Garage doors get a great deal of use and require special care to continue working properly. A few things you can do to keep your garage door well maintained are: Check all components of your door to make sure they are functioning correctly. Look for broken or bent pieces that may need repair. Lubricate the axles and rails and be sure they are in place and tight. If adjusting the sensitivity of your door, be certain the setting is in accordance with the manual. The weather sealant should be intact and free from cracks. You can also wash your garage door with car wax to control dirt and extra moisture. More here
