Garage Door Opener Repair in Longmont
Opener humming, blinking or reversing? Licensed technicians fix it fast, with guaranteed repairs.
Opener Running but the Door Won't Cooperate?
A garage door opener is a motor, a gear or belt drive, a circuit board and a pair of safety sensors working together. When one piece fails, the symptoms can look the same: the door won't open, won't close, or stops and reverses halfway. The trick is figuring out which part is actually at fault before replacing anything.
Sometimes it isn't the opener at all. A broken spring makes the door too heavy for the motor, and the opener gets blamed. That's why a licensed technician checks the whole system, from the springs and cables to the sensors and the motor, and then fixes the part that failed. Call (720) 698-9749 for your free estimate.
Signs You Need Garage Door Opener Repair
The motor hums but the door doesn't move
Often a stripped drive gear, a broken spring or a disengaged trolley. Call (720) 698-9749.
The door reverses before it closes
Usually misaligned or dirty safety sensors, or a close-force setting that's off.
The remote or keypad stopped working
Dead batteries, lost programming, a lock-mode button, or a failing logic board receiver.
Grinding, clicking or rattling
Worn gears, a loose chain or a tired belt. Catching it early can save the motor.
The opener light keeps flashing
Most openers flash a diagnostic code. The pattern points us to sensors, wiring or the board.
The door opens partway, then stops
Travel limits out of adjustment, a binding track, or springs that can no longer balance the door.

Garage Door Opener Repair: What We Fix
Safety sensor alignment and wiring
The photo-eyes near the floor have to see each other for the door to close. We realign them, clean them and repair damaged wiring.
Gears, sprockets and drive parts
Plastic drive gears wear out, especially in openers that have been lifting a heavy or poorly balanced door. We replace worn gears and sprockets.
Logic boards and receivers
Power surges and age can kill an opener's circuit board. We test and replace boards and receivers. Call (720) 698-9749.
Chains, belts and rails
A sagging chain or stretched belt makes noise and slips. We adjust or replace it and check the rail.
Remotes, keypads and wall buttons
We reprogram remotes and keypads and replace wall buttons that have quit. Ask about it when you call (720) 698-9749.
Opener replacement and installation
When a repair costs more than the opener is worth, we install a new chain-drive, belt-drive or wall-mount opener. Common opener brands include LiftMaster, Chamberlain and Genie.

Simple Checks Before You Call
Before you call, try a few simple things. Check that the opener is plugged in and the outlet works, and look at the breaker. Make sure the lock or vacation button on the wall control isn't switched on. Look at the two safety sensors near the floor: if one light is off or blinking, wipe the lenses and make sure nothing is blocking the beam. And swap the batteries in your remote.
If none of that helps, don't keep cycling the opener. Repeated attempts can burn out the motor or strip the gear, especially if a spring is broken. If the door is down and you need to get out, pull the red emergency release cord only when the door is fully closed, never when it's open. Then call (720) 698-9749.

Opener Repair Questions
Why does my garage door reverse before it closes?
The most common cause is the safety sensors near the floor. If they're misaligned, dirty or blocked, the opener reverses as a safety measure. Clean and realign them; if that doesn't work, call (720) 698-9749.
How long do garage door openers last?
Many openers last roughly 10 to 15 years, depending on how often they're used and how well the door is balanced. A heavy, unbalanced door wears an opener out faster.
Should I repair or replace my opener?
If it's a sensor, remote, gear or board, repair usually makes sense. If the motor has failed on an older unit, a new opener is often the better value. Your free estimate covers both options.
Is a belt-drive or chain-drive opener better?
Belt drives are quieter, which matters if there's a bedroom over the garage. Chain drives are a little noisier but sturdy and usually cost less.
