What this service covers

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

  • Opener repair

    Logic boards, gears, capacitors, travel limits, and remotes diagnosed and repaired on site where it makes sense.

  • New opener installation

    Belt, chain, and wall-mount jackshaft openers installed and tuned, with smart and battery-backup options.

  • Sensors, remotes, and keypads

    Safety sensor alignment, remote and keypad programming, and Wi-Fi or myQ setup.

When to repair vs replace an opener

  • The opener hums but the door does not move, often a gear or capacitor

  • It runs then reverses, usually a sensor or travel limit

  • It is loud, slow, or from before 1993 with no photo eyes

  • You want quieter operation, battery backup, or phone control

We had a great experience with this garage door company! They responded quickly and came out right away to fix our garage door. The service was fast, professional, and very affordable. Everything is working perfectly now, and we really appreciate how easy they made the whole process. We would definitely use them again in the future and highly recommend them to anyone needing garage door repairs!

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!
