AfterSingle Car Door in Alpharetta, GA
A single car garage door installation in Alpharetta typically runs $1,100 to $2,800 depending on material, insulation, and whether you’re replacing an existing door or framing a new opening. Most single car doors measure 8×7 or 9×7 feet and install in a single day. Brock Garage Doors Alpharetta gives you a written price before any work starts, so the number you approve is the number on the invoice. If you’re weighing a new door against a repair, our Garage Door Installation team can walk you through both options honestly.
Call (229) 404-6747 and a live person answers, day or night. We’re an independently owned location within the Garrison Partners network, run to a standard most homeowners only find out about after they’ve been burned once.

When You Need Single Car Door
Most Alpharetta homeowners call us for a single car door in one of these situations. If any of them sound familiar, the fix is usually straightforward and the quote is free.
- Your current door is sagging or binding. A single car door that scrapes the track or hangs unevenly has likely worn hinges, a bent track, or tired springs. Replacing the door and hardware together often costs less long-term than chasing individual repairs.
- The bottom panel is rotted or dented. Alpharetta’s humid summers take a toll on older wooden doors. If the bottom section is soft, water is getting in, and that means the door’s structural integrity is already compromised.
- You’re converting a carport to a garage. Single car openings are the most common carport conversion in Alpharetta’s older neighborhoods like Kingsley Estates and Martin’s Landing. You need a door, track, springs, and an opener, all installed to code.
- The door is original to a 1990s-era home. Many single car doors installed during Alpharetta’s 1990s building boom are hitting the end of their service life. The springs, rollers, and panels all wear on roughly the same schedule.
- You’re selling your home and the door shows its age. A single car garage door is one of the first things a buyer sees from the street. A straight, clean, quiet door does more than a fresh coat of paint for curb appeal.
- Your opener struggles to lift the door. If your motor strains and the door shudders, the issue may be the door itself, too heavy for the opener after years of absorbed moisture in the panels.
Our Single Car Door Process
We follow the Garrison Standard on every install. It’s not a slogan; it’s a checklist that keeps the job predictable from the first call to the final walkthrough.
- You call and a live person answers. No voicemail tree, no callback queue. We ask about your current door, take measurements, and schedule a site visit at a time that works for you. Call (229) 404-6747 now if you want a real conversation.
- A uniformed technician shows up in the window. You’ll know exactly who’s arriving. Our techs are background-checked and wear the Brock uniform. We measure the opening, check the framing, and assess the existing hardware.
- You get a written price before any work starts. Not a ballpark, not a verbal estimate. A line-item written quote covering the door, hardware, labor, and disposal of the old door. You decide; we don’t pressure.
- We install the door and opener. The old door comes down, the new one goes up. Panels, track, torsion spring, cables, rollers, and weather seal. If you have an existing opener that’s compatible, we’ll test it and tune it; if not, we’ll install a new one from a brand we train on, like LiftMaster or Genie.
- We clean the site and walk you through it. Old door, packaging, and hardware go with us. You get a walkthrough of the door’s balance, opener operation, and safety features.
- Your 365-Day Done Right Promise is in writing. If the door fails within a year due to our workmanship or a faulty part, we come back and make it right at no charge. That’s not a verbal assurance; it’s on paper.
Single Car Door Pricing in Alpharetta
Here’s the honest range. Single car door installation in Alpharetta typically falls between $1,100 and $2,800, and most of our jobs land between $1,400 and $2,200. The spread comes down to what you actually need.
| Item | Typical Range |
|---|---|
| Basic steel single car door (non-insulated) | $1,100 – $1,500 |
| Insulated steel single car door | $1,500 – $2,200 |
| Basic steel single car door (non-insulated) | $1,100 – $1,500 |
| Insulated steel single car door | $1,500 – $2,200 |
| Premium single car door (wood composite or full view glass) | $2,200 – $2,800 |
| New garage door opener (if needed) | $350 – $600 |
| Old door removal and disposal | Included |
What moves the price? Material is the biggest factor. A non-insulated steel door is the most economical choice and fine for a detached garage or one you don’t spend time in. An insulated door matters if your garage is attached to your home, because Alpharetta summer heat seeps through uninsulated panels and raises your cooling bill. The brand also matters: a Chamberlain or Clopay door with a heavier gauge steel costs more than a builder-grade panel, and it lasts longer.
Spring type is another variable. Most single car doors use a torsion spring (the coiled spring mounted above the door that carries the lifting load). If your framing is tight, we may recommend extension springs, which changes the hardware setup and the price slightly. The age of your opener matters too: a LiftMaster from the last decade may pair fine with a new door; a 1990s Genie may not communicate with modern safety sensors.
We give you a free, written estimate. The price you see before the job is the price you pay after. If we find something unexpected during install, like rotted framing or a misaligned header, we stop and go over the additional cost with you before proceeding. No surprises at the door.
Why Alpharetta Homeowners Choose Brock Garage Doors
Most companies can hang a door. The difference shows up six months later, when the door still opens quietly, seals tight, and doesn’t fight the opener. We’re built around the idea that a repair or install should stay fixed, and we put that belief in writing.
Our technicians are trained on eight major brands, including LiftMaster, Chamberlain, and Genie, so the opener and door are matched correctly from the start. We work on Clopay doors regularly, and we know the panel profiles and hardware kits specific to each line. That prevents the kind of mismatched repair that leaves a door balancing poorly two months later.
Brock Garage Doors Alpharetta is an independent, locally operated location. We agreed to work to the Garrison Standard because it’s a better way to run a trade business: show up in the window, price in writing, do it by the book, leave it clean, stand behind it for a year. The standard applies to every job, whether it’s a $150 repair or a $2,500 install.
FAQs – Single Car Door
How much does a single car garage door cost in Alpharetta?
A single car garage door in Alpharetta runs $1,100 to $2,800 installed, with most jobs falling between $1,400 and $2,200. The price depends on insulation, material, and whether you need a new opener. Call (229) 404-6747 for an exact quote, free and in writing.
How long does it take to install a single car garage door?
Most single car door installs are completed in a single day, usually four to six hours from arrival to cleanup. We remove the old door, hang the new one, install or tune the opener, and haul away the debris. The site is clean before we leave.
Can I just replace the panels instead of the whole door?
Sometimes, but it’s rarely the better deal. On a single car door over 15 years old, the springs, rollers, and track are worn on the same timetable as the panels. Replacing only the panels often leaves you with mismatched hardware and a door that still binds or sags. We’ll tell you honestly if a panel swap makes sense, and we’ll give you written numbers for both options.
Do you install openers with a single car door?
Yes. We install and program openers from LiftMaster, Chamberlain, and Genie, matched to the weight and travel of your new door. We also inspect your existing opener to see if it’s compatible before recommending a replacement, because some older units won’t support modern safety features.
Is it cheaper to install a single car door than a double car door?
Yes. Single car doors use less material, smaller springs, and a lighter opener, so the total install typically runs $600 to $1,200 less than a comparable double car door. The per-square-foot cost is similar, but the smaller footprint lowers the overall bill.
