How long has it been since your garage door was last serviced?

Your garage door should be serviced yearly unless you are experiencing a specific problem. It is important to periodically inspect and service your garage door and garage door opener to ensure that they work at peak performance and to prolong the life of the entire system. You can visually inspect the garage door yourself, taking a look at cables, springs, tracks, hinges, and rollers for signs of wear. Some of these parts are under extreme tension, so do not attempt to adjust, repair or remove these parts or anything attached to them.

A good yearly checkup on your door should include lubricating the door, springs, hinges, rollers, pulleys, and bearings. It should also include adjusting the spring tension, testing the safety features of the garage door opener, and inspecting the rollers, hinges and cables for defects/wear. Lastly, all screws and bolts should be tightened. If a specific problem needs to be addressed, schedule an appointment with one of GDD technicians, to have the parts serviced, and make the necessary adjustments and repairs.

Refer to the diagram of the garage door and parts, which will help you identify the parts. This can be extremely helpful when you call with your door problems.
