Classic Tune-Up


Similar to what you would do with your car, we call this a tune up in the garage door business. Having a professional check your springs, brackets, cables, and other attached hardware is a great way to avoid larger problems down the road.

This annual maintenance keeps your door and motor operating more efficiently, safely, and promotes the life of the door, ultimately saving you money in the long run. At GDU, we believe proper maintenance is just as important as purchasing the right door.
