Repair a Garage Door
"Called around and 770 Garage Door gave the lowest quote by far. No surprises, just honest, quality work. The opener was installed the same day. Can't beat the price or the service."
Jimmy R. Install or Replace a Garage Door Opener
"Couldn't be happier with the experience using 770 Garage Door. After calling a few companies, they gave the cheapest quote, but what really stood out was how professional and knowledgeable the technician was. Showed up on time, explained exactly what needed to be done, and completed the job right."

Common garage door problems in Brentwood
Plain answers from our technicians: what each problem looks like, what you can safely check, and when to call.
- Broken springIf you heard a loud bang in the garage and now the door won't go up, a spring has most likely broken. Leave the door closed, don't run the opener, and call a technician to replace the spring.
- Door won't openA door that won't open usually has a broken spring, a power problem, or a remote that lost its signal. Check the power, the lock and the remote first, and if the motor runs but the door doesn't lift, stop and call a technician.
- Door off trackA door comes off its track when one or more rollers pop out, usually after the door gets hit, a cable slips, or the track bends out of line. Stop using it right away, because a door off track can twist and fall.
- Snapped cableLift cables run from the bottom corners of the door up to the drums by the springs, and they carry the weight together with the springs. If a cable is loose, frayed or snapped, the door will hang crooked and should not be used until it is repaired.
- Opener not workingWhen an opener stops working, the cause is often simple: no power, a locked wall console, a dead remote, or blocked safety sensors. If those check out and the motor hums, clicks, or runs without moving the door, the opener needs a repair.
- Door reverses or won't closeA door that starts down and then goes back up almost always has a safety sensor problem: the two small sensors near the floor are dirty, bumped out of line, or blocked. If the sensors are fine, the cause is usually the opener's settings or something binding in the track.
- Noisy garage doorMost garage door noise comes from dry or worn rollers, loose hardware, or an opener chain that needs attention. Squeaks and rattles are usually a tune-up fix, but a sudden bang, grinding or popping can mean a part is failing.
- Remote or keypad not workingIf the wall button opens the door but the remote or keypad does not, the problem is almost always the remote, the keypad, or the opener's receiver, not the door itself. Start with fresh batteries and the lock button on the wall console, then reprogram if needed.
