AfterFast, Reliable Gate Installation Across Dunwoody
A new driveway gate in Dunwoody typically runs $2,400 to $7,800 depending on whether you need a single swing leaf on an existing post or a full slide gate with new pilasters, operator, and access controls. Most installations take one to three days on site, and the price is quoted and agreed before any work starts. If your HOA board is debating a gate replacement off Mount Vernon Road or along Chamblee Dunwoody Road, call (877) 610-2993 and Hal will walk the site himself.
We know Dunwoody’s gates because we work on them every week. The tight rights of way, the aging brick pilasters, the HOA boards that need three signatures before a work order moves. Our Gate Installation team has been untangling these jobs since 2001, and we do the welding and pilaster work right there in your driveway, not in some shop across town.
Why Gatewood Fence & Gate Is Dunwoody’s Preferred Gate Installation Company
Hal Gatewood started this company in 2001 and put his name on the shop. That is not marketing. That is the oldest accountability there is. When a Dunwoody HOA president calls about a sagging double gate at a subdivision entrance off Womack Road, Hal shows up himself, looks at the hinge posts, and tells the board what actually needs fixing instead of what is easiest to bill.
The 90-Day Done Right Promise is stamped in writing on every job. If a gate we installed in Dunwoody isn’t right ninety days later, one call brings us back. No argument, no dispatch runaround. A live person answers the phone 24 hours a day, seven days a week. You won’t get a voicemail tree or a call center three states away. You’ll get someone who knows the difference between a clay-heaved post in Dunwoody and a rusted one in Sandy Springs.
Our crews carry parts for Linear, Viking, Ghost Controls, and DoorKing operators so we aren’t waiting on a warehouse when your Perimeter Center office park gate is down. We serve Dunwoody from our Atlanta office, but the people who show up live in this metro and drive these roads daily. They know that a slide gate track crossing a Dunwoody right of way freezes differently than one on flat ground in Brookhaven.
Our Gate Installation Services in Dunwoody
Sliding Gate Installation
In Dunwoody’s 1970s and 1980s HOA subdivisions, a sliding gate is often the only legal option. The platted shared driveways and narrow rights of way mean a swing leaf cannot open without crossing a property line or blocking a neighbor’s easement. We install slide gates on existing brick pilasters whenever they’re sound, but in many Dunwoody communities those pilasters have shifted on the red clay and need re-plumbing before a modern operator can anchor safely. A typical sliding gate installation in Dunwoody runs $3,800 to $7,800 including the operator, rack, safety photocells, and a new loop detector.
Swing Gate Installation
For single-family driveways on Dunwoody’s brick ranch and colonial lots, a swing gate remains the most affordable option. Single leaf installations start around $2,400 when the existing posts are plumb and structurally sound. We install both single and double swing gates with operators sized for the leaf weight, and we always check the hinge post before quoting, because in Dunwoody a post that looks fine in March may have heaved an inch by August. The price you’re quoted is the price you pay.
Double Gate Installation
Double driveway gates are common at Dunwoody subdivision entrances and estate lots where the opening exceeds fourteen feet. These jobs hinge on, literally, the hinge posts. Two leaves create twice the pull on the posts, and on Dunwoody’s expansive clay, a post set shallow will lean within two or three wet/dry cycles. We set posts below the frost line, brace them during concrete cure, and weld the leaf frames on site so they match the opening exactly, not a factory template. Double gate installations in Dunwoody typically range from $4,500 to $9,000 depending on operator type and access control.
Security Gate Installation
The corporate campuses along the Perimeter Center corridor and the I-285/Ashford Dunwoody area need gates that stay working during installation, not just after it. A security gate at an office park can’t be down for three days while someone orders parts. We stage the work, keep one lane operational, and coordinate with your facilities team on access windows. For commercial security gate installations in Dunwoody, expect $6,000 to $15,000 depending on gate type, operator duty cycle, and whether you need card readers, keypads, or integration with existing access control.

Trusted Brands We Service in Dunwoody
We install and service operators from Linear, Viking, Ghost Controls, and DoorKing, and we carry common control boards, photocells, and loop detectors on our trucks for Dunwoody jobs. That matters when a 1980s DoorKing operator at a subdivision entrance off Vermack Road finally dies and the HOA board wants it running before the weekend. We also work on LiftMaster, FAAC, BFT, Elite, and Mighty Mule equipment. If you have an operator that’s no longer manufactured, we can usually retrofit a modern board without replacing the entire gate.
Common Gate Installation Problems We See in Dunwoody Homes
- Shared driveway gates crossing property lines: Dunwoody’s 1970s and 1980s plats created shared driveways and narrow rights of way. After years of clay heave, a swing gate that once stayed inside the property line now swings out over the neighbor’s easement. The fix is usually converting to a slide gate mounted inside the line.
- Pilasters shifting on red clay: North Georgia’s red clay expands when wet and shrinks when dry, and over decades that movement heaves brick pilasters out of plumb. You can’t anchor a modern operator to a leaning post. We re-plumb or rebuild the pilaster before we mount anything.
- Abandoned 1980s telephone-entry wiring: In many Dunwoody communities the original telephone-entry and loop-detector systems were hardwired into operators that are no longer manufactured. That wiring is now abandoned in place, and a new operator needs a full control board replacement just to talk to modern access controls.
- Slide gate tracks cracking in winter: Ice storms hit the Atlanta metro periodically and hard. A slide gate track poured across a narrow Dunwoody right of way cracks when water freezes in the channel, and a new operator torquing the rack against a jammed gate burns out quickly. We pour tracks with proper drainage and expansion joints for this climate.

FAQs - Gate Installation in Dunwoody
Yes, if the pilasters are structurally sound, and in Dunwoody that means checking for clay heave first. We re-plumb and reinforce pilasters before anchoring a slide gate operator, and we can usually reuse the existing brick columns with steel reinforcement added inside. A slide gate keeps the leaf inside your property line, which resolves the easement issue permanently. Call (877) 610-2993 and Hal will inspect the posts and give you a straight answer on whether they can be saved.
It almost always means replacing the control board and often the loop detector, but not necessarily the entire gate or operator housing. In Dunwoody HOA communities we frequently find the original 1980s telephone-entry wiring abandoned in place, and a modern board has to be installed to restore basic open and close function. The gate itself, if the steel is sound, usually stays. We’ll tell you what can be salvaged before we quote anything.
We stage the work so one lane stays operational, and we coordinate access windows with your facilities team. The old gate runs until the new track and rack are ready, then we swap during a scheduled window, usually after hours. For security gates on the Perimeter Center corridor we also temporary-mount keypads and loop detectors so access never goes dark. Call (877) 610-2993 and we’ll walk the site and build a staging plan.
Red clay shrinks when it dries out, and a hinge post that was set in 1983 has been through forty years of wet and dry cycles. The post leans slightly, the gate drops, and the latch no longer lines up. The gate didn’t sag in the middle. The post moved at the base. We fix the post first, then re-hang the leaf and re-weld the hinge points on site. Fix the panel without the post and you’ll fix it twice.
Current UL 325 standards require an inherent entrapment sensor plus external safety photocells and a reversing edge or equivalent on any automated gate serving a Dunwoody driveway or community entrance. We install photocells and reversing edges on every automation job, and we test the force settings with a pressure gauge, not a guess. A gate that can’t sense a child or a car is a lawsuit waiting for your HOA board. Call (877) 610-2993 and we’ll make sure your install meets code before the inspector ever looks at it.
