AfterNew Door Installation in Alpharetta, GA
New garage door installation in Alpharetta typically runs $1,150 to $3,400 for a complete door and hardware package, with most mid-range steel doors landing between $1,400 and $2,200 installed. The job usually takes one day when we’re replacing an existing door with standard dimensions, and we handle everything from removing the old door to hauling it away and setting the new one on fresh tracks. If you’re weighing a new door against patching an old one, call (229) 404-6747 and we’ll walk you through the numbers before you commit to anything.
Brock Garage Doors Alpharetta installs new doors the same way we handle every Garage Door Installation: written price first, clean site when we leave, and a 365-day guarantee on the work in writing. Wade Mercer runs this location, and every installation follows The Garrison Standard, the operating discipline we’ve worked under since 2001 within the Garrison Partners network.
When You Need New Door Installation
Some doors can be repaired for another few years. Others are done. Here’s what tells us it’s time to replace rather than patch:
- Structural rust or rot on the lower panels. Alpharetta’s humidity and spring rain cycles work on steel and wood doors from the bottom up. Once the bottom rail is compromised, panel replacement is a short-term fix at best.
- A door that’s visibly off-track or sagging. When the door no longer sits square in the opening, the tracks, hinges, and rollers are all wearing unevenly. Continuing to operate it accelerates the failure.
- Repeated spring or cable failures within a two-year window. A door whose weight has shifted or whose hardware is undersized will keep eating springs. At that point the door itself is the problem, not the spring.
- Insulation failure or drafts you can feel from inside the garage. Homes in Alpharetta with attached garages lose conditioned air through old, uninsulated doors. A new insulated door changes the temperature in the garage measurably.
- Noise that keeps getting worse. Grinding, popping, rattling. If lubrication and roller replacement didn’t quiet it down, the door’s frame and panel joints are fatigued.
- An old door you simply don’t trust anymore. If you’re flinching every time the opener kicks on, there’s a reason. A new door with fresh hardware removes that variable entirely.
The common thread: when repair costs within a year approach half the cost of a new door, replacement is the better math. We’ll tell you that plainly at the estimate, even if it means we lose the repair job.
Our New Door Installation Process
Here’s exactly how a new door installation runs with Brock Garage Doors Alpharetta, from first call to final walkthrough. No surprises, no price that moves at the door.
- Call and talk to a live person. You reach a real human at (229) 404-6747, any hour, any day. Explain what you’re seeing. We’ll ask a few questions about the door’s age, size, and condition, then schedule a site visit at a time that works for you.
- Site assessment and measurement. A background-checked, uniformed technician arrives, takes precise measurements of the opening, checks ceiling clearance and side room, and inspects the existing tracks and opener for compatibility. We note anything that affects the install: low headroom, uneven floors, out-of-square openings.
- Written quote, item by item. Before any work is approved, you get a written price that breaks down the door, hardware, tracks, labor, and haul-away of the old door. The number on that sheet is the number on the invoice. It doesn’t move.
- Scheduling with a real arrival window. We tell you when we’ll be there and we show up in that window. The Garrison Standard doesn’t allow for no-show behavior or “sometime between 8 and 5” vagueness.
- Installation day. We remove the old door, inspect the framing, install the new door, tracks, springs, and hardware, then connect or re-set your opener. We test the full cycle multiple times, adjust balance and travel limits, and verify safety sensor alignment.
- Walkthrough and written guarantee. Before we leave, we show you the finished door in operation and hand you the written 365-day guarantee covering the installation. If anything fails within that year, we return and correct it at no charge. We also haul away the old door and leave the garage floor cleaner than we found it.
New Door Installation Pricing in Alpharetta
Here’s the honest math on new door installation in Alpharetta, based on what we actually see across Milton, Roswell, Johns Creek, Cumming, and the surrounding north metro areas:
- Single steel door, non-insulated: $1,150 to $1,600 installed
- Single steel door, insulated (R-6 to R-9): $1,400 to $2,200 installed
- Double-wide steel door, non-insulated: $1,600 to $2,400 installed
- Double-wide steel door, insulated: $2,000 to $3,400 installed
- Premium materials (wood-look composite, full-view glass, custom finishes): $2,800 to $5,500+ installed
What moves the price: door size and width, insulation R-value, material and finish, whether the opener needs replacement or can be reused, and any structural work to the opening itself. High-lift track conversions for homes with taller ceilings also add labor.
We install doors from Clopay, Amarr, and Wayne Dalton most often in this market. If you have a Chamberlain or LiftMaster opener, we’ll match the new door to it and adjust the opener settings so everything works as one system. If you have a Genie opener, same approach.
Every quote is free and in writing. Call (229) 404-6747 and we’ll schedule the site visit. You’ll know the exact number before you decide anything.
FAQs – New Door Installation
Direct answers to the questions homeowners in Alpharetta ask us most about new door installation.
How much does a new garage door cost in Alpharetta?
A new garage door in Alpharetta ranges from $1,150 to $3,400 installed for standard steel doors, with most homeowners spending between $1,400 and $2,200. Premium materials like composite wood-look or full-view glass push the price higher, typically $2,800 and up. Call (229) 404-6747 for an exact quote based on your door size and preferences, free and in writing.
Can you install a new door the same day?
Same-day installation is possible when the door size is in stock at our local supplier and your schedule allows it, but most installations are scheduled within a few days of the estimate. We’ll tell you at the site visit what’s realistic for your specific door. If it’s an emergency, a live person answers at (229) 404-6747 and we’ll tell you what’s available right now.
Is it cheaper to repair or replace a garage door?
If the door is structurally sound and under 15 years old, repair is usually cheaper. But when repair costs within a year approach half the installed price of a new door, replacement is the better financial decision. We’ll give you both numbers at the estimate and let you decide, no pressure either way.
Does a new garage door include new tracks and hardware?
Yes. We install new tracks, hinges, rollers, and springs with every new door. Reusing old hardware with a new door creates premature wear and voids most manufacturer warranties. Our installation package covers all of it, and it’s itemized in the written quote you approve before work starts.

Why Alpharetta Homeowners Call Brock Garage Doors
We’re an independently owned and operated location within the Garrison Partners network, which means we run on local accountability with a standard behind it.

Every technician who arrives at your home is background-checked and in uniform. The written price is handed to you before a single bolt turns. The 365-day guarantee is on paper, not a verbal promise. And if a covered repair fails, the second visit is free. Not a fee item, not a negotiation. Part of every job.
We train on eight major brands, including Clopay, Amarr, Wayne Dalton, LiftMaster, and Chamberlain, so the door you get is matched correctly to the opener and hardware you already have. The right fix for the specific system, not a generic workaround.
For new door installation in Alpharetta, call (229) 404-6747 and talk to Wade Mercer’s team directly. You’ll get straight answers, a written number, and a door that’s installed right.
