Opener repair guide

The Most Common Garage Door Opener Repairs

This is garage door opener repair as it really happens, counted from our own job records instead of guessed. Of 186 opener repair jobs, safety sensors came up most, then gears and drive parts, travel limits and force settings, and the arm and bracket hardware. Boards and motors were rare.

What this service covers

Real work by background-checked local technicians, quoted at a flat rate you approve before anything begins.

  • Safety sensors

    Photo-eyes realigned, cleaned, rewired or replaced. This was the single most common opener repair in our records.

  • Gears, sprockets, chains and belts

    Stripped drive gears, worn sprockets and loose or snapped chains and belts repaired or replaced.

  • Travel limits and force

    Open and close limits reset and force adjusted so the door stops where it should.

  • Arm, bracket and hardware

    Door arms, brackets and bolts that work loose and leave the opener pulling on nothing.

  • Boards, capacitors and motors

    Electronics diagnosed and replaced where the opener is worth keeping. These were the rarest repairs.

From our job records

Counted from our own completed opener repair records, not including new openers or remotes.

Where we do this

Quick checks before you call

  • Look at the sensors near the floor. A dark or blinking light usually means misaligned or blocked eyes.

  • Pull the emergency release and lift the door by hand. A heavy door points to springs, not the opener.

  • Listen to the opener. A hum or click with no movement can be a gear, a capacitor or a spring.

  • Check that the wall button works while the remote does not. That points to the remote, not the opener.

How it works

  2. 2

    On-site check and flat quote

    The technician checks the door and springs first, then the opener, and gives you a flat price to approve.

  3. 3

    Done and tested

    We repair the fault, reset the limits and force, and test the sensors before we leave.

After putting off a broken garage spring for over a year, I finally called G Brothers Garage Doors. I only wish I had done it sooner. I found them on social media and got an immediate response. Scheduling was easy, and Boddrick showed up exactly when he said he would at 8:45 AM. He took one look at the issue and confidently said he could fix it and had the springs in the truck. He replaced both springs quickly for the exact quoted price with no surprises. While testing the door, he noticed noise in the rails and took the time to tune everything up as well. Professional, knowledgeable, efficient, and honest. The kind of service that is hard to find these days. If you need garage door work done right the first time, call G Brothers. No question. Highly Recommend!

G Brothers came to check out our garage door issue within a half an hour of calling them. They turned around a quote within that same day and I was able to schedule my garage door opener replacement within 48 hours. This was much faster than I expected (my issue wasn’t an emergency). The garage door works much better now than I knew it could (older garage door). I highly recommend working with G Brothers! And will certainly be going back to them with any future garage door needs.

I highly recommend this company. They did a great job! I needed a new 2-door and single door garage door and they came the very next day, did a great job, and were the best experience. I've had at least 3 companies come out and do work on my garage doors over the past 10 years and wouldn't use any of them again. I will be using G Brothers again and again, they did great work at the price they quoted. They were on time, did the work quickly, and it looks and works great!

So grateful for these guys, they helped me out so quickly and at a great price! When my old door jammed up and got crunched they were the only ones who could within a day fix it and they work so fast it only took them an hour and a half to install a completely new door and springs, great work ethic and super nice guys! Other companies told me it would be weeks till they could get a new door and wanted to charge me thousands more, I would highly recommend these guys to anyone!
