How Much Does Gate Parts & Welding Cost in San Antonio?

Most gate parts and welding repairs in San Antonio run between $150 and $850, with the typical job landing around $285 to $450. That range covers everything from replacing a bent hinge or broken weld on a residential driveway gate to fabricating custom brackets for commercial slide gates. Final price depends on the part, the metal thickness, whether we’re working on-site or in our shop, and how much disassembly the gate requires to reach the damaged section.

Calder Gate Repair gives you a written price before any work starts, so the number you approve is the number on the invoice. No surprises at the door. If you’re looking at unusual damage, send us a photo and we’ll give you a ballpark over the phone. For an exact quote, call (361) 314-4803.

Gate Parts & Welding Cost Breakdown (2026)

San Antonio’s gate repair market prices differently from Dallas or Houston because of our soil movement, heat cycles, and the mix of older welded-steel ranch gates and newer aluminum driveway gates. Here’s what we’re seeing across the city in 2026:

Service	Typical Price Range	What It Includes
Broken weld repair (single point, on-site)	$150 – $275	Grind-out, re-weld, primer, paint touch-up on one cracked or snapped joint
Hinge replacement (welded steel hinge)	$180 – $320 per hinge	Cut off old hinge, weld new hinge, align gate, test swing
Gate frame crack repair	$200 – $450	Weld reinforcement plates across the crack, grind smooth, repaint
Custom bracket fabrication	$95 – $250 per bracket	Measure, cut, drill, weld, and finish a custom bracket for opener arms, sensors, or latch mounts
Gate frame straightening	$250 – $650	Heat and mechanical straightening of a sagging or bowed steel gate frame
Full weld reinforcement (multiple joints)	$350 – $850	Addressing 3+ welds, adding gusset plates, re-squaring the gate, full repaint of repaired areas
Aluminum gate TIG welding	$200 – $500	Specialist TIG work on aluminum driveway gates, including filler rod matching and finish blending
Gate picket or finial reattachment	$75 – $180 per piece	Welding or mechanically refastening decorative elements that have broken loose

Those numbers assume the gate is accessible and the metal is in weldable condition. Heavily rusted steel in places like Alamo Heights or Terrell Hills where gates are older sometimes needs extra prep work, which adds $40 to $90. The key cost drivers are metal type, thickness, whether the gate has to come off its hinges, and how much rust or paint removal the weld zone needs.

We decode the trade terms before we start. When we say “grind-out,” we mean we remove the old weld and rust down to clean metal before laying a fresh bead. “Gusset plate” is just a triangular steel plate we weld across a joint to spread the load so it doesn’t crack again in the same spot.

Replacement Parts Pricing

Sometimes the welded part isn’t repairable and needs replacement. Here’s what common gate parts cost in San Antonio:

• Steel gate wheels (V-groove or flat): $45 – $160 each, installed
• Slide gate rollers and bearing blocks: $90 – $220 per set
• Gate hinges (heavy-duty steel): $60 – $140 per pair, plus install
• Gate latch and strike assemblies: $75 – $250 installed
• Cantilever gate truck assemblies: $200 – $450 per truck
• Gate stops and catch posts: $80 – $190 installed

We keep common hinge sizes, wheels, and latch parts on our trucks so most repairs happen same day. If you need something we don’t have on hand, we source it locally and usually return within 48 hours.

What Affects Gate Parts & Welding Pricing in San Antonio

Not all gate welding jobs quote the same, even when they look similar from the street. Here’s what moves the number:

• Metal type and thickness. Thin-wall tube steel, which dominates the affordable gate market in neighborhoods like Stone Oak and Cibolo, welds differently than the heavy 3/16-inch plate steel common on older properties in King William or Monte Vista. Aluminum takes TIG welding and a different filler rod, which costs more per joint.
• Whether the gate comes off its hinges. Some welds are reachable with the gate in place. Others, especially on the bottom rail or inside a box frame, require unbolting or cutting the gate free and working on sawhorses. That’s another hour of labor and sometimes a second technician to handle the weight.
• Rust and paint condition. San Antonio’s humidity and our occasional Gulf-driven rain mean gates here rust faster than in El Paso. We see gates in Alamo Ranch and Helotes with the bottom rail completely rotted from sprinkler overspray. Weld prep on rusty steel takes grinding, wire-brushing, and sometimes cutting back to solid metal.
• Access and terrain. Gates on sloped driveways in the Hill Country take more setup time. If we’re welding overhead, lying on the ground, or working around a fence line with no clearance, that’s extra labor.
• Gate type and operation. A swing gate with a broken hinge weld is straightforward. A slide gate with damaged track wheels and a cracked carry frame is a larger job. Cantilever gates, common in commercial and larger residential properties, have more weld points and heavier components.
• Emergency vs. scheduled service. Same-day welding calls, especially for a gate that won’t close and is leaving a driveway open to the street, cost more than work booked a day or two out. That said, Calder doesn’t charge hidden emergency fees. The price you’re quoted is the price you pay, even at 2 a.m.

How to Save on Gate Parts & Welding

Welding repairs are priced by the joint and the hour, so the easiest ways to keep costs down are about reducing labor time and catching problems early:

1. Get the gate looked at when you first notice it sagging or dragging. A gate that scrapes the driveway in Schertz or Converse is telling you a weld is failing. Catch it early and it’s a $200 fix. Let it go until the frame twists and you’re looking at $600 or more.
2. Keep sprinkler heads aimed away from gate posts and the bottom rail. This is the single biggest cause of weld failure we see in San Antonio. Irrigation water sitting on the bottom rail rusts it from the inside out.
3. Address multiple welds in one visit. If we’re already on-site, running a second or third weld bead costs far less than a separate trip. The trip charge, setup, and cleanup only happen once.
4. Send photos before we come out. A clear photo of the damage helps us bring the right filler rod, grinder discs, and replacement parts the first time. That’s less labor on site and usually a lower final invoice.
5. Ask about combining welding with opener adjustments. If your gate opener is working harder because of a dragging wheel or a sagging hinge, fixing the weld and the alignment in one visit is cheaper than two separate calls.

Welding vs. Replacing: Which Costs Less?

The math usually favors repair, but not always. Here’s the decision framework we use with customers, and the numbers behind it.

When Welding Saves Money

If your gate frame is under 10 years old, the metal is sound apart from a single failed weld, and the overall structure is square, welding is the clear winner. A $200 weld on a $1,800 gate is a 90% savings over replacement. We see this constantly with Mighty Mule and Ghost Controls setups where the opener is fine but the gate frame cracked at a stress point.

Steel gates up to about 14 feet wide and 7 feet tall almost always justify repair. The replacement cost for a comparable gate in San Antonio runs $1,500 to $4,500 installed, and that doesn’t include re-mounting your opener, moving the keypad, or adjusting the safety sensors.

When Replacement Makes More Sense

If the bottom rail is rotted through in more than one spot, or the frame is twisted beyond straightening, replacement often wins. A gate with three or more failing welds at corners, a rotted bottom rail, and sagging pickets is a metal fatigue problem that welding won’t permanently solve. In those cases, we tell you straight up. We’d rather sell you a new gate once than a recurring weld repair that fails every eight months.

For anything in between, the 365-Day Done Right Promise takes the risk out of the repair decision. If we weld it and the weld fails within 365 days, Calder comes back at no charge. That’s stated in writing on every job, so choosing repair doesn’t mean gambling.

What to Expect During a Gate Welding Appointment

Here’s how a typical welding job goes when you book Calder Gate Repair in San Antonio:

1. Call or book online. A live person answers 24/7. You describe the problem, send photos if you can, and get a price range before we dispatch.
2. Technician arrives with a trackable ETA. You’ll get a live arrival time you can follow on your phone, not a four-hour window. Our techs are background-checked and uniformed.
3. On-site assessment and written quote. Before we touch anything, we inspect the damage and hand you a written price. You approve it, we start. If we find hidden damage, we stop and re-quote before doing additional work.
4. Weld prep and repair. We grind off the old weld, rust, and paint around the joint, then weld with the right process for your metal. Most single-joint repairs take 30 to 45 minutes of welding time, plus setup and cleanup.
5. Paint touch-up and alignment check. We prime and paint the repaired area, then swing the gate to verify alignment and latch function. If an opener is mounted, we cycle it to make sure the gate doesn’t bind.
6. Digital invoice and guarantee. You get a digital invoice you can pay from a link, plus the written 365-Day Done Right Promise on the repair. Before-and-after photos are part of the standard record, so you can see exactly what was done.

Why San Antonio’s Climate Is Hard on Gate Welds

We get asked constantly why gates in San Antonio rust faster than people expect. The answer involves our particular combination of heat, humidity, and alkaline soil. San Antonio sits on clay-heavy soils that expand and contract with moisture changes. When the ground moves, gate posts shift slightly. That movement concentrates stress at the hinge welds and the corners of the frame, which is exactly where we see cracks start in neighborhoods from Shavano Park to Windcrest.

Add in our summer heat. Surface temperatures on a dark steel gate in August can hit 150°F or more, which accelerates paint degradation. Once paint fails, bare steel meets San Antonio’s morning humidity and the metal starts oxidizing. Rust under a paint bubble doesn’t look serious until the weld underneath is compromised. By the time the gate starts sagging, the repair is bigger than it would have been six months earlier.

Cantilever slide gates have their own issue here. The counterbalance section sits low to the ground, and if the track area doesn’t drain well during our heavy spring rains, that lower frame section sits in water. We saw a rash of this after the October flooding in 2024 across Leon Valley and parts of the Medical Center area.

Gate Parts We Replace Most Often in San Antonio

Some parts wear out before others. Here’s what’s on our trucks most weeks:

• V-groove wheels on sliding gates. We replace these constantly across commercial properties near Port San Antonio and residential slide-gate installs in Castle Hills. Metal wheels wear, nylon wheels crack in heat, and both fail faster when the track is misaligned.
• Heavy-duty hinges on steel swing gates. Bearing hinges fail at a predictable rate on 400+ pound gates. We keep multiple sizes on the truck and weld replacements in on-site.
• Gate latch hardware. San Antonio’s heat kills spring-loaded latches. The spring loses tension or the latch pin seizes. These are quick replacements that immediately restore security.
• Cantilever truck bearing assemblies. Commercial properties in the Brooks and Southtown areas run their gates hundreds of cycles a day. Bearings in the trucks wear, and when they do, the gate starts bouncing and chattering on the track, which then causes weld failures elsewhere.
• Opener mounting brackets. When a gate sags or a weld fails, the opener arm takes the load. We often see cracked opener brackets on LiftMaster and FAAC installs where the gate frame itself was the root cause. We fabricate reinforced brackets that are thicker than factory spec.

What Welding Process We Use and Why It Matters

Your gate’s metal dictates the welding process. We match the process to the material, because using the wrong one is how you get brittle welds that crack at the edge of the bead.

For standard steel gates, we run MIG welding with solid wire and a gas shield. It’s fast, clean, and strong when the base metal is clean. For thicker plate steel, we’ll use flux-core wire, which penetrates deeper and handles mild surface contamination better. For aluminum gates, which are common on newer construction in far north San Antonio like Timberwood Park and Sonterra, we use TIG welding with AC current and a matched filler rod. Aluminum welds cooler than steel and requires more prep, which is part of why it prices higher per joint.

We also grind every weld smooth before painting. A lumpy weld isn’t just ugly; it creates a stress riser at the toe of the bead. That’s a technical way of saying the crack will start right where the weld meets the parent metal if the transition isn’t smooth. Grinding and blending the weld into the surrounding steel is what makes a repair last 10 years instead of 10 months.

Common Gate Welding Problems We Fix

Every week we see the same handful of failures on San Antonio gates:

Cracked weld at the hinge plate

The hinge carries the entire weight of the gate, and the weld where the hinge plate meets the frame is the highest-stress point. When this weld cracks, the gate drops and starts dragging. Repair involves cutting out the old weld, re-aligning the gate, and laying a full-penetration weld around the hinge plate. On heavy gates, we add a reinforcement plate to spread the load. Typical cost: $180 to $320 per hinge.

Broken picket welds on the bottom rail

Decorative steel gates with individual pickets weld each picket to the top and bottom rails. When the bottom rail starts rusting, picket welds pop. We see this all over neighborhoods like Oak Hills and Jefferson with older custom steel gates. Each picket reattachment runs $75 to $180, and if more than ten pickets are involved, we’ll quote reinforcement of the bottom rail instead, which usually makes more financial sense.

Cracked opener arm bracket

The bracket that connects your gate opener arm to the gate frame takes constant cyclical loading. On BFT and Linear installs, we see these brackets crack when the gate is slightly out of square and the arm is fighting the gate. We cut off the cracked bracket and weld a thicker custom bracket in its place, which runs $95 to $250 depending on the opener model and bracket design.

Sagging gate frame at the corner joints

When the angle of a gate frame’s corner joint cracks, the entire gate parallelogram begins to sag. The fix is cutting out the failed weld, re-squaring the gate with clamps, re-welding the corner, and adding a gusset plate for reinforcement. Depending on gate size, this runs $250 to $500 and is one of the most common repairs we do across Leon Springs and the Boerne area.

Gate Opener Brand Compatibility and Welding

We weld and replace parts on gates running any opener brand, and we’re factory-familiar with nine major manufacturers: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. That matters because welding repairs often interact with opener mounting. If we’re cutting and re-welding a frame, the opener arm geometry changes slightly. We account for that so the opener doesn’t bind after the repair.

LiftMaster and DoorKing dominate the commercial side in San Antonio, while residential installs lean heavily Mighty Mule and Ghost Controls in the DIY-installed segment and FAAC or BFT in professionally installed automation. Viking and Elite show up more on large estate gates in the Dominion and Anaqua Springs. Linear has a strong presence on older apartment and condo gates throughout the city. Whatever brand you have, the welding work underneath is the same, but the way we contour the brackets and position the mounting points is brand-specific.

Safety Notes on Gate Welding

We say this clearly because it matters: gate welding and gate spring work involve real hazards. Gates are heavy. A 16-foot steel driveway gate can weigh 600 pounds or more, and when it comes off its hinges, it’s a crush hazard. Welding involves high-temperature arcs, molten metal, and fumes. The grinding that precedes welding throws sparks and metal dust. This is not the place for a weekend DIY attempt, especially on any gate that’s suspended, under tension, or connected to an opener.

If your gate has fallen off its hinges, do not try to lift it back into place with a car jack and do not remove hinge pins while the gate is under load. Call us at (361) 314-4803. Our technicians carry proper lifting equipment, weld curtains, and fire extinguishers on every truck. You watch the work, ask questions, and keep all ten fingers.

How Calder Gate Repair Prices Differ From Handyman Welding

You can find a mobile welder on a marketplace app who will charge less per hour. We know, because we’ve repaired their work. Here’s what the difference actually is:

• We’re gate specialists, not general fabricators. We understand gate geometry, hinge alignment, opener integration, and the specific failure modes gates develop. A general welder can lay a bead. We know where the bead needs to go so the gate doesn’t crack again six months later.
• Our pricing is upfront and written. You know the number before we start. No hourly meter running. No “it was more work than expected” conversation at the end.
• The 365-Day Done Right Promise covers the weld. If the weld fails within 365 days, Calder returns at no charge. That’s written on every invoice. A marketplace welder won’t give you that.
• We invoice digitally and document everything. Before-and-after photos, a detailed line-item invoice, and a payment link. The Relay Standard means you get a trackable arrival time, a uniformed tech, and a paper trail.
• We carry insurance and work under the Relay Home Co. banner. Established in 2009, the Relay Home Co. family operates each location independently, with the Relay Visibility Guarantee behind every job.

How Much Does a Custom Gate Cost in San Antonio?

Sometimes the question isn’t about repairing a weld; it’s about building or installing something new. For reference, custom steel driveway gates in San Antonio run $2,500 to $7,500 for a standard double swing gate installed, with larger or ornate designs going higher. Aluminum frame gates with steel pickets run $2,000 to $5,000. Slide gates add $800 to $2,000 over swing gates due to the track, trucks, and cantilever hardware.

If you’re having a gate built, ask about weld quality upfront. We recommend specifying full welds on all pickets and gusset plates at all three rail intersections. The gate builder who quotes $800 less is almost certainly stitch-welding. Stitch welds look fine on day one and fail at the top of every picket within three or four years, especially with San Antonio’s heat cycling expanding and contracting the steel.

FAQs – Gate Parts & Welding Cost

How much does it cost to weld a gate in San Antonio?

A single weld repair on a steel gate in San Antonio typically costs $150 to $275. That includes grinding out the old weld, re-welding the joint, and touching up the paint. If the joint needs a reinforcement plate or the gate has to be removed to reach the weld, expect $250 to $500. Call (361) 314-4803 for a free estimate with a written price before any work starts.

Is it cheaper to repair or replace a gate?

Repair is cheaper than replacement in about 85% of cases we see. A $200 weld repair versus a $3,000 replacement is a massive difference. Replacement makes sense when the frame is rotted in multiple places, the gate is structurally compromised, or repair costs would exceed 50% of replacement value. Calder’s 365-Day Done Right Promise means if we recommend repair and the weld fails within 365 days, we come back free.

How much do gate hinges cost to replace?

Replacement steel gate hinges cost $60 to $140 per pair for the parts, plus $180 to $320 in labor per hinge if welding is required. We provide the written price before the work begins, and the 365-Day Done Right Promise covers the weld and the hinge alignment. Call (361) 314-4803 for a same-day quote.

Can you weld an aluminum gate?

Yes. Aluminum gate welding in San Antonio runs $200 to $500 per joint because TIG welding requires specialized equipment, argon shielding gas, and matched aluminum filler rod. The prep work also takes longer because aluminum oxidizes within minutes of cleaning. We weld aluminum gates regularly, particularly in newer north-side communities where aluminum automation installs are common.

Can you come today for a gate welding repair?

In most cases, yes. Calder Gate Repair keeps welding equipment, common gate parts, and replacement hardware on our trucks, so same-day service is available across San Antonio, including Alamo Heights, Stone Oak, Helotes, and Schertz. Call (361) 314-4803 and a live person will give you an arrival window and a price range on the spot.
