AfterFast, Reliable Gate Installation Across Stone Mountain
Gate installation in Stone Mountain, GA typically runs $2,400 to $7,800 for a complete driveway gate system, and most jobs are finished in one to two days once the gate is fabricated. The number moves based on what’s under your grass, which around here means granite. If you’re calling from 30087 or the park corridor, your quote will likely land higher than a neighbor in Tucker simply because we’re anchoring into ledge, not dirt. Call (877) 610-2993 and Hal will give you a straight answer before anyone steps on your property.
We’ve been setting gates on top of one of the largest exposed granite plutons in North America since 2001. That’s not a marketing line. It’s the reason our trucks carry hammer drills, epoxy anchors, and surface-mount base plates as standard equipment, while crews from outside the area show up with an auger and a prayer.
Why Gatewood Fence & Gate Is Stone Mountain’s Preferred Gate Installation Company
Hal Gatewood started this shop in 2001, and his address is published. That matters to the folks in Stone Mountain who’ve already been burned by a national outfit that quoted one number on the phone and handed them a different invoice at the door. Around here, you can drive to the shop and look the person who wrote your estimate in the eye. The name is on the shop, and the shop is down the road. That’s the oldest accountability there is.
Stone Mountain customers call us because we answer the phone. A live person, 24 hours a day, not a voicemail tree and not a call center three states away. When a gate motor dies on a Sunday night off Rockbridge Road, the person who picks up knows what a swing gate is and will tell you honestly whether it can wait until morning.
Our Gate Installation team works from the Atlanta office, but the crews who show up in Stone Mountain know the difference between the clay pockets in 30083 and the ledge lines in 30087. That local knowledge changes how we quote, how we dig, and how long the gate stays square. Every job carries Hal’s 90-Day Done Right Promise in writing. If it’s not done right, one call brings him back. No runaround.
Our Gate Installation Services in Stone Mountain
Driveway Gate Installation
Most Stone Mountain driveway gates are ornamental steel or aluminum across a 12 to 16 foot opening, and the job starts with the hinge posts. Given how many properties along the park corridor sit on shallow bedrock, we often core into granite and epoxy-set anchors rather than auger a three-foot hole. A single swing gate across a standard residential driveway in Stone Mountain runs $2,800 to $5,200 installed, including the operator if you want it automated.
Pedestrian Gate Installation
Pedestrian gates around Stone Mountain’s 1960s and 1970s ranch homes tend to be matched to the driveway gate, sharing the same picket style and finish. These are smaller jobs, typically $900 to $2,400, but the post-setting challenges don’t shrink just because the gate does. We still core, epoxy, or surface-mount where ledge is close, because a wobbly pedestrian post is the first thing that fails when kids swing on it.
Sliding Gate Installation
Sliding gates are the right answer when your driveway has a slope or when a swing gate would arc into parked cars or the house. In Stone Mountain, we see a fair number of these on lots off Rockbridge Road where driveways pitch up from the street. A residential sliding gate with a rack-and-pinion motor runs $3,800 to $7,800 depending on length and whether we need to pour a steel-reinforced track beam. The granite actually helps here, because the track foundation needs a solid base anyway.
Swing Gate Installation
Swing gates remain the most common choice in Stone Mountain’s 30083 and 30088 neighborhoods, especially where homeowners are replacing 1990s ornamental gates that have sagged out of square. We hang the gate, but we start at the hinge post. A gate sags in the hinge post, not in the middle, and that is where we start. A typical single swing gate with a modern operator and safety edges runs $2,900 to $5,600 in this market.

Trusted Brands We Service in Stone Mountain
We install and service FAAC, BFT, Linear, and Viking operators, and we’re certified on nine major gate brands total, including LiftMaster, Ghost Controls, and DoorKing. For Stone Mountain customers, that means we stock the control boards, photocells, and remotes for the brands already on your property, so a retrofit doesn’t mean waiting a week on a part from a warehouse. If you’ve got an old FAAC swing operator gone obsolete, we’ll tell you straight whether a new board gives it five more years or whether you’re better off replacing the whole unit. Fix the panel without the post and you’ll fix it twice.
Common Gate Installation Problems We See in Stone Mountain Homes
- Shallow post footings that hit ledge. Across ZIP codes 30087 and 30088, we routinely hit granite 12 to 18 inches below the surface. Original posts set in shallow holes sit on a concrete cap with only 6 to 8 inches of grip, and a few years of clay movement wobbles the whole column loose.
- Cracked welds at corroded post collars. The 1990s ornamental gates common to 30083 and 30088 are now 20 to 30 years old. Hinge pins corrode, welds at the post collars crack, and panels start sagging at the latch end.
- Obsolete single-button DC operators. Many Stone Mountain gates still run on early 2000s motors that lack modern entrapment protection. Those units are no longer supported by manufacturers, and retrofitting them to meet current safety standards usually isn’t worth the labor.
- Rust at buried post bases. Stone Mountain’s thin clay over granite means moisture has nowhere to drain. Buried steel post bases rust faster here than in Tucker or Clarkston, even though the climate is the same on paper. The soil is the difference.

It’s the only way to set a post that won’t float. Every price is quoted and agreed before any work starts, and there’s no trip charge inside DeKalb County. Seniors and veterans get a permanent 10% discount, and any repair over $200 takes $40 off. Call (877) 610-2993 for an exact quote. Estimates are free.

FAQs - Gate Installation in Stone Mountain
Stone Mountain sits on a massive granite pluton with only a thin layer of clay over bedrock, and DeKalb County’s red clay swells in wet winters and shrinks in summer droughts. In Tucker, that movement is absorbed by deeper soil. In Stone Mountain, the clay has nowhere to go but sideways against a post set in a shallow hole, so the column heaves and twists. We combat it by coring into the granite, epoxy-setting anchors, or using surface-mount base plates instead of concrete footings. Call (877) 610-2993 for an evaluation and a free estimate.
Yes, in most cases. We do it regularly on the ornamental iron gates common throughout 30083 and 30088. The gate frame itself is often fine, but the hinge pins need replacement and the post collars need re-welding before a new operator goes on. We install current FAAC, BFT, Linear, or LiftMaster operators with photocells, safety edges, and entrapment protection that meets UL 325. The retrofit typically runs $1,100 to $2,100. Call (877) 610-2993 and we’ll tell you if your gate is worth saving.
We core into the granite with a hammer drill, epoxy-set galvanized steel anchors 18 to 24 inches deep, and bolt the post base directly to the rock. When the post is in an area where coring isn’t practical, we use a surface-mount base plate with multiple anchors. This is standard procedure for us on properties in 30087 and near the park corridor. On a 1963 brick ranch off Rockbridge Road, our tech found an original hinge post that had bottomed out on ledge with only a few inches of concrete grip. We cored, anchored, and surface-mounted a new LiftMaster LA400 operator, bringing the gate back to level.
Expect 7 to 12 years from a quality operator in Stone Mountain’s climate, and that’s honest, not a sales number. High seasonal humidity and summer heat stress the control boards and capacitors faster than in drier regions. Terminal strip corrosion is the usual failure point. A motor in a sun-exposed box on a south-facing gate will run on the shorter end of that range. We recommend operators from FAAC, BFT, and Linear for this market because their sealed boards handle humidity better than older open-frame designs. Call (877) 610-2993 for a free second opinion on any written estimate.
Yes, if the gate is automated and swings outward toward the street, a vehicle loop detector or a photocell safety system is required for safety and practical for everyday use. Rockbridge Road carries steady traffic, and an outward-swinging gate without a loop will close on a car waiting at the edge of the drive. We install loop detectors, photocells, and safety edges on every automated gate in Stone Mountain, and the package is included in our quoted price, not added on later. Call (877) 610-2993 for a free measure and written price.
