Garage door opener safety repairs
Fixing auto reverse, safety sensors, wall buttons, remotes and openers that don't work.
A garage door opener should stop and reverse when the door meets something in its way, and the safety sensors near the floor should stop it from closing on a child, a pet or a car. When either doesn't work, the door can hurt someone.
Most of these are adjustments: setting the opener's force, lowering and lining up the sensors, or replacing a wall button or remote. An old or damaged opener may be replaced. For the door itself, see floors, windows and surfaces.

What affects the price
- Adjust or replace

- The door itself
- If the door is out of balance or a spring is worn, the door needs work before the opener will run right.
Common questions
How do I check my garage door's auto reverse?
Lay a piece of wood flat on the floor under the door and close it. The door should stop when it touches the wood and go back up. Also try waving something through the sensor beam while the door closes: it should reverse.
