New Garage Door Installation

A new garage door is one of the highest-return upgrades on a home, for curb appeal, insulation, and quiet operation. G Brothers installs Clopay, Amarr, Wayne Dalton, and Hormann doors, with a free in-home quote, flat pricing, and a clean, code-correct installation.

What this service covers

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

  • In-home measure and quote

    We measure the opening, review styles and insulation, and give you a flat installed price with no pressure.

  • Insulated steel, wood, and full-view doors

    Options for Colorado weather, from insulated steel for an attached garage to modern full-view aluminum.

  • Complete installation and haul-away

    We remove the old door, install the new door and hardware, tune the opener, and take the old door away.

Signs it is time for a new door

  • An old, uninsulated door. An aging door on an attached, heated garage leaks heat all winter and runs loud. A new insulated door is quieter and easier on your energy bill.

  • Repairs that keep adding up. When an older door needs fix after fix, a new one ends the cycle and starts fresh with new springs, rollers, and a warranty.

  • Storm or impact damage. Hail, wind, or a bumper tap that dents or cracks several panels usually calls for a full replacement, not a patch.

  • A refresh before you sell. A new garage door is one of the highest-return upgrades before a sale, and it refreshes the look of the whole front of the house.

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!
