A garage door and opener servicing generally costs between $120-$150, but many companies will run door service specials periodically for less than $100.
Routine garage door and opener service typically includes a comprehensive inspection of panels, hinges, bearing, cables, drums, track and opener for any irregularities. This also typically includes re-tensioning the springs for proper balance as well as making any adjustments to the door to make things run as smoothly as possible. A garage door technician should also check the opener limits and sensitivity to ensure safe operation.
