AfterFast, Reliable Gate Parts & Welding Across Stone Mountain
Gate hinge replacement in Stone Mountain typically runs $185-$400 per hinge, and we complete most on-site repairs in a single visit because the granite ledge underfoot demands it. You can’t dig a standard post hole when bedrock sits a foot down, so the whole job changes. If your 1990s ornamental gate sags toward the latch post or the hinge post wobbles when you pull it, call (877) 610-2993 and Hal will tell you straight what’s fixable and what isn’t. We’ve been welding and repairing gates locally since 2001, and nobody knows Stone Mountain’s granite problem like a crew that’s drilled into it for two decades.
Why Gatewood Fence & Gate Is Stone Mountain’s Preferred Gate Parts & Welding Company
Hal Gatewood’s name is on the shop and on every invoice. That’s not marketing language; it’s how we’ve worked since 2001. Stone Mountain homeowners see the same face when they call for an estimate and when the job gets done. We answer the phone with a live person, 24/7, and the person who shows up knows the difference between a gate that can be welded and one that needs its post reset in granite.
Our 90-Day Done Right Promise is written on every job. If the weld cracks or the hinge pin works loose inside ninety days, one call brings us back. No runaround, no dispatch queue, no third-party call center. Stone Mountain is a community where word travels fast, and after 29 years of standing behind our work, most of our calls come from neighbors who already know what we do. We’re certified to service LiftMaster, FAAC, Linear, Viking, DoorKing, Ghost Controls, BFT, Elite, and Mighty Mule operators, and we stock common hinge pins, gate rollers, and latch parts so most repairs in 30083, 30086, 30087, and 30088 don’t wait on a parts order.
Whether you’re off Rockbridge Road, near Stone Mountain Village, or back in a subdivision off South Hairston, we schedule Stone Mountain calls with local crews who don’t need GPS to find you.
Our Gate Parts & Welding Services in Stone Mountain
Hinge Replacement
Hinge pins on 1990s ornamental steel gates corrode from the inside out, especially where moisture sits against granite that can’t absorb it. A seized or snapped hinge pin in Stone Mountain usually means the gate has been dragging for months while the post slowly shifted. We cut out the old hinge, weld the new one square, and check the post’s footing at the same time. You don’t fix the hinge and ignore the post. A gate sags in the hinge post, not in the middle, and that is where we start.
Post Replacement
This is the big one in Stone Mountain. When a post wobbles, we pull it and find what’s underneath. Most of the time it’s granite ledge 12 to 18 inches down, and the original installer poured a concrete cap that never got below the frost line or into solid soil. We reset the post with a hammer-drill anchor system or a surface-mount base plate, depending on what the rock allows. The new footing bolts into bedrock instead of sitting on top of it. That’s the difference between a post that stands for thirty years and one that wobbles again in three.
Rail Repair
Steel tube rails crack at the welds where they meet the hinge and latch posts, especially when the gate has been racking out of square from a shifting footing. We grind out the cracked weld, re-square the frame, and weld a fresh bead. If the rail itself is rusted thin from Stone Mountain’s humidity, we sleeve or replace that section rather than laying a new weld over weakened steel. Fix the panel without the post and you’ll fix it twice.
Custom Welding
Stone Mountain has a lot of ornamental gates that aren’t made from stock parts anymore. The 1990s installs used custom collar plates, odd rail spacing, and decorative scrolls that nobody catalogs. We fabricate and weld on site, in your driveway, so you’re not hauling a 300-pound gate across DeKalb County. If a section of scrollwork rusted through or the top rail cracked at a bend, Hal can match the profile and weld it back so it looks original. On-site welding is usually half the cost of replacing the gate, and it keeps the work where you can watch it happen.

Trusted Brands We Service in Stone Mountain
We’re certified to work on nine major gate operator brands, and Stone Mountain’s older stock leans heavily toward three: Linear, Viking, and Ghost Controls. Those single-button DC operators from the late 90s and early 2000s are obsolete now, and manufacturers no longer carry safety entrapment parts for them. We keep retrofit kits and compatible safety photocells in stock for common Linear and Viking models, and we can rebuild a Ghost Controls swing arm without replacing the whole motor. For homeowners around Mountain Industrial Boulevard or off Hugh Howell Road, that usually means a repair instead of a full operator replacement. If you’re in Stone Mountain and need Gate Parts & Welding help, we’ll tell you honestly whether your old operator can be brought up to current safety standard or whether it’s time to retrofit.
Common Gate Parts & Welding Problems We See in Stone Mountain Homes
- Wobbling hinge posts cut short by granite ledge. We routinely pull posts from 30087 and the park corridor that were set only 6 to 8 inches deep because the auger hit rock and the installer stopped. The concrete cap has no grip below it. After a few Atlanta clay swell-shrink cycles, the entire column works loose and the gate starts dragging.
- Cracked welds at the post collar. 20 to 30 year old wrought-iron and tubular-steel gates develop stress cracks where the rail welds meet the hinge post collar. The gate flexes every time it cycles, and old welds were never designed for thirty years of Stone Mountain humidity working on shallow footings.
- Corroded hinge pins from trapped moisture. Stone Mountain’s thin clay over granite means water has nowhere to drain. Moisture sits against buried post bases and wicks up into hinge barrels. Pins rust, snap, or seize, and the gate starts to bind.
- Obsolete single-button DC operators with no safety parts. Early LiftMaster, FAAC, and BFT models from the 1990s use control boards and entrapment sensors that haven’t been manufactured in over a decade. When those fail, you can’t just order a replacement board. The operator has to be retrofitted with current safety equipment or replaced.
We serve all of Stone Mountain, including 30083, 30086, 30087, and 30088, and we’ve seen every one of these failures more times than we can count.

FAQs - Gate Parts & Welding in Stone Mountain
Yes. Standard auger digging won’t work when granite ledge sits 12 to 18 inches below the surface, so we use a hammer-drill anchor system or a surface-mount base plate instead. The post bolts into the rock rather than relying on a shallow concrete cap. Last spring along Rockbridge Road, we pulled a wobbling 1990s ornamental steel swing gate and found the original post footing was only 6 inches deep, sitting right on ledge. We reset the hinge post with drilled anchors, welded a fresh collar, and reused the existing FAAC operator with new safety photocells. The gate hasn’t racked since. Call (877) 610-2993 to have us look at your post.
If the post wobbles at all, welding a brace is temporary at best. A brace transfers the load to a post that’s already failing, and you’ll be back within a year or two. The honest answer is to pull the post, inspect the footing, and reset it properly, then weld any collar cracks once the post is solid. In Stone Mountain we usually find the original hole stopped at granite ledge with 6 to 8 inches of grip. That’s the root problem. Call (877) 610-2993 and we’ll tell you what your post actually needs.
Sometimes, but not always. Early LiftMaster, FAAC, and BFT single-button DC operators use boards and entrapment sensors that are no longer manufactured. If the operator uses a simple contact strip or single-button control, a full retrofit to current UL 325 safety standards usually means replacing the control board, adding photocells, and often replacing the operator itself. We’ll assess your specific model and tell you the least expensive path to a safe gate. Call (877) 610-2993 for a free estimate.
We pull the post and inspect the footing. In Stone Mountain, a floating post usually means the original installer hit ledge 6 to 8 inches down and poured concrete right on top of the rock. The concrete cap has no mechanical grip, so when the thin clay around it swells and shrinks, the whole column moves. We drill anchor bolts into the granite, set the post with a base plate or a deeper core hole, and pour a new footing that ties the post to the rock. That ends the wobble permanently. Call (877) 610-2993 and we’ll dig into yours.
Yes, and the granite makes it worse. Stone Mountain’s thin clay over bedrock means rainwater pools against buried post bases instead of draining down. That trapped moisture accelerates rust on hinge pins, post collars, and the base of the gate frame. Combined with hot humid summers, the corrosion cycle in Stone Mountain speeds up noticeably compared to nearby areas with deeper soil. The fix is sealing post bases, using stainless hinge pins where possible, and keeping drains clear around the footing. Call (877) 610-2993 for an inspection.
