AfterWeld & Rust Repair in San Antonio, TX
Weld and rust repair on a gate in San Antonio typically costs between $180 and $650, depending on how far the corrosion has spread and whether the hinge or latch mounts need to be rebuilt, as detailed in our How Much Does Gate Repair Cost? (2026 Price Guide) - San Antonio, TX. Most repairs take one visit, and at Latch and Post Gate Repair San Antonio we give you a written price before any work starts. If your gate is sagging, creaking, or showing flaking metal near the bottom rail or hinge plates, call us at (325) 252-5195 and we’ll tell you exactly what we’re seeing.
What most people don’t realize about San Antonio is that our soil and humidity are hard on steel. The combination of summer humidity, winter moisture, and the occasional sprinkler overspray means gate frames rust from the inside out. A gate can look fine on the outside while the tubing near the base is quietly losing its structural integrity. When that happens, a weld is the only fix that holds. This is a subset of what we handle under our broader Gate Repair in San Antonio work, and it’s one of the most common requests we get from homeowners in neighborhoods like Stone Oak, Alamo Heights, Helotes, and Cibolo.
We’re part of the Cedarwell family, and we’ve been doing this since 2009. Our focus is narrow: our Gate Repair services. Not fences, not general welding jobs, not handyman work. That means we know how a Viking operator arm mounts to a steel post, how a Ghost Controls hinge wears, and where rust tends to hide on a DoorKing or Elite frame. Cody Beckman owns Latch and Post Gate Repair San Antonio, and every job we take reflects the same standard: the latch holds, the post carries, and the family inside stays safe.
When You Need Weld & Rust Repair
Rust on a gate isn’t always obvious. Here are the signs we see most often in San Antonio, and what they usually mean:
- Sagging at the latch side. The gate was square when it was installed, but now it dips an inch or two. That usually means the hinge side has weakened from rust and the frame is twisting under its own weight.
- Flaking or bubbling paint near the bottom rail. Steel rusts from the inside on gates. By the time you see bubbling, the wall of the tubing has thinned. Welding a patch over it without cutting back to clean metal won’t hold.
- A crack at a weld joint. The original factory welds or the installer’s field welds are often the first point to fail. A hairline crack near a hinge plate will grow every time the gate cycles.
- Creaking or groaning that doesn’t go away with lubrication. That sound is often the hinge pin wearing against a rusted sleeve inside the hinge barrel. The fix is cutting out the old hinge and welding in a new one.
- Latch misalignment that keeps coming back. If you’ve adjusted the latch twice and it keeps dropping out of alignment, the gate frame or the post itself is moving. Welding a reinforcement gusset or rebuilding the post mount stops it.
- White, chalky corrosion on aluminum gates. Aluminum doesn’t rust like steel, but it corrodes. The white powder is aluminum oxide, and it weakens joints wherever two pieces meet. We weld aluminum gates too.
If you’re seeing any of these, don’t wait for the gate to fail completely. A gate that falls off its hinges is dangerous, especially for kids and pets. Call (325) 252-5195 and we’ll send a background-checked, uniformed technician to look at it.
Our Weld & Rust Repair Process
Every weld and rust repair we do in San Antonio follows the same careful sequence. No shortcuts, and you’ll know what’s happening at each step.
- Inspection and written quote. We look at the entire gate: hinges, latch, frame rails, post mounts, and operator arm if it’s electric. Then we hand you a written price before any work begins. No pressure, no surprises.
- Surface preparation. We grind back the rusted area until we hit clean, solid metal. That often means removing more material than the homeowner expected. If we welded over rust, the repair would fail within a year.
- Welding and reinforcement. We weld the cracked joint, rebuild the thinned section with new steel, or fabricate a replacement bracket. For brands like Viking and Ghost Controls, we match the mounting points exactly so the operator arm lines up without binding.
- Rust treatment and coating. We apply a rust-inhibiting primer and a topcoat that’s matched to your gate’s finish. On aluminum gates, we use a corrosion-resistant epoxy primer made for non-ferrous metal.
- Alignment and testing. We re-hang the gate, adjust the latch, and cycle it by hand. If it’s an electric gate with a DoorKing or Elite operator, we run the full open and close cycle, check the safety edges, and make sure the motor isn’t straining.
- Cleanup and photo. We lay drop cloths before we start, wear shoe covers if we step inside your home, and we take a photo of the cleaned-up work area before we leave. That photo is part of the Cedarwell Care Promise, and it’s included on every visit.
Your floors stay clean. Your kids can be asleep in the next room. We use quiet tools where we can, and we ask before we move anything. C.A.R.E. isn’t a slogan for us. It’s how we set up the truck: Clean up like it’s our own home, Ask before we touch anything, Respect the family’s time and quiet hours, Explain the price before the work.
Weld & Rust Repair Pricing in San Antonio
You deserve real numbers, so here they are. These are the ranges we typically quote for weld and rust repair work in the San Antonio area:
| Repair Type | Typical Cost in San Antonio | What’s Included |
|---|---|---|
| Small crack weld (single joint) | $180 – $280 | Grinding, weld, primer, touch-up paint |
| Hinge replacement (one hinge) | $220 – $350 | Old hinge removal, new hinge welded, alignment |
| Bottom rail rust repair | $300 – $500 | Rusted section cut out, new steel welded in, full refinish |
| Post reinforcement (base rust) | $350 – $650 | Post base rebuild, gusset plates, alignment, paint match |
| Aluminum gate corrosion repair | $250 – $450 | Oxide removal, weld repair, epoxy primer, topcoat |
| Gate frame rebuild (extensive rust) | $500 – $900+ | Multiple rail replacements, post reset, hinge work |
What changes the price most is how much rust we find after the grinder comes out. Surface rust is quick. Rust that has eaten through the tubing wall means cutting out sections and fabricating new steel to match. The other factor is whether the gate is electric and may need Automatic Gate Repair. A weld near an operator mount on a Viking or Ghost Controls system requires extra care to keep the motor aligned, which adds a small amount of time.
You’ll see your exact number in writing before we touch anything. No deposits, no hidden line items. If the repair isn’t right, our 365-Day Done Right Promise covers it: we make it right, no argument, no fine print. Every job we’ve done since 2009 carries that promise.
FAQs – Weld & Rust Repair
Is it cheaper to weld a gate or replace it?
Weld repair is almost always cheaper. In San Antonio, a full gate replacement typically runs $1,500 to $4,500 or more, while most weld repairs land between $180 and $650. A gate with a rusted bottom rail or cracked hinge is usually worth repairing with Gate Realignment if the rest of the frame is sound. We’ll tell you honestly if we think a repair won’t hold long-term. Call (325) 252-5195 for a written assessment.
How much does rust repair cost on a San Antonio gate?
Most rust repairs in San Antonio run between $180 for a small crack weld and $650 for post base reinforcement. The average job we handle falls around $300 to $450. You’ll get a written quote before any work begins, so there’s no guesswork. Call us and describe the rust; we’ll give you a range over the phone and send a technician for the exact number.
Can you fix a rusted gate post without replacing the whole gate?
Yes, and we do it regularly. If the post is still standing straight and the rust is limited to the base or the hinge mount area, we can cut out the corroded section and weld in new steel with reinforcement plates. This saves the frame and the post, and it usually costs a third or less of a full replacement. The post has to be structurally sound above the rust, and we’ll verify that during the inspection.
How long does a weld repair last on a gate?
A properly prepared and coated weld repair typically lasts 5 to 10 years in San Antonio’s climate, which is about the same as the original gate. The two things that shorten the life are welding over rust and skipping the rust-inhibiting primer. We do neither. We grind to clean metal, weld with the right filler for the metal type, and finish with a coating that stands up to our summer humidity. The 365-Day Done Right Promise backs the repair in case anything falls short.
Do you work on electric gates with rust damage?
Yes. We’re factory-trained on Viking, Ghost Controls, DoorKing, and Elite operators, and we know how rust affects the mounting points where the arm connects to the gate. When we repair rust near an operator mount, we rebuild the mounting surface so the motor doesn’t strain and the safety edges function correctly. If your electric gate is showing rust, call us before the frame starts torquing against the motor.
