Linear gate opener welding and fabrication in San Antonio typically runs $220 to $480 installed, and most jobs are completed same-day when we have your model on the truck. That price includes cutting out the failed component, fabricating a replacement bracket or mount, and welding it back in place. Most San Antonio homeowners discover this problem the same way: the gate starts making a grinding noise, sags visibly at the hinge side, or one day just refuses to move and you can hear the motor straining against a broken mount.
We’re an independent gate repair shop in San Antonio, not affiliated with Linear. But we stock Linear-compatible replacement parts and fabricate mounts, brackets, and reinforcement plates for almost every Linear residential operator still in service around Bexar County. Nico Alvarez, our owner and lead technician, has been cutting, fitting, and welding gate hardware since his days pulling wire across Southern California, and he’ll tell you the same thing every time: Linear operators are solid machines. What fails first is usually what they’re bolted to.
Key Takeaways:
- Linear welding and fabrication jobs in San Antonio run about $220 to $480 installed.
- Most failures are the mounting bracket, hinge reinforcement plate, or a cracked weld at the post.
- We write the price down before any work starts, no exceptions.
Which Linear Models This Applies To
The welding and fabrication we do applies to nearly every residential Linear opener: the LRA series, the LDO series linear arm operators, the classic APeX and MegaCode swing and slide models, and the older LS and LD slide gates still running in San Antonio’s established neighborhoods like Alamo Heights and Terrell Hills. What changes is the bracket geometry. A Linear slide gate operator bolts to a steel post plate that sees constant lateral force. A swing gate arm pulls against a welded hinge plate. Same brand, completely different failure points.
Before ordering any part or starting any weld, we match the bracket to your model number. The tag is usually on the operator housing or the control board cover. If the tag is gone, we measure the mount spacing and the clearance from the gate frame to the operator. Here’s the gotcha a lot of San Antonio owners run into: a generic universal bracket off a shelf may bolt up, but the hole pattern for the LDO series is offset by roughly half an inch from the older LD series. Eyeballing it gets you a gate that binds. OEM Linear brackets are what we recommend for slide operators. For swing gates, a properly fabricated steel reinforcement plate usually outperforms the factory part, because the original was often just too thin for years of Texas heat cycling and the occasional wind gust off a summer storm.
Styles & brands we work with


Signs Your Linear Welding & Fabrication Is Failing
- Gate sags toward the latch side. The hinge welds or the post plate have begun to stretch or crack. You’ll see a visible gap at the top hinge when the gate is closed. This will only get worse, and every cycle bends the metal a little more.
- Grinding or popping noise when the gate opens. A cracked weld flexes under load. That pop you hear is the broken weld face opening and closing as the gate moves. The motor is working harder to compensate.
- Gate reverses or stops mid-cycle. A misaligned mount trips the Linear operator’s obstruction sensor. The board thinks something is in the way. Nothing is, but the bent bracket makes the motor draw enough current to look like it.
- Visible rust streaks at weld points. In San Antonio’s humidity swings, a small crack lets moisture into raw steel. The rust bleeds through paint within a season. By then the weld is already compromised underneath.
- The operator moved or leans. On slide gates, the operator post plate can shear its lag bolts. The whole motor housing kicks sideways. You might notice it first as a new noise, or the chain dragging loose.

AfterReplacement Cost & What’s Included
In San Antonio, expect to pay $220 to $480 installed for most Linear welding and fabrication repairs. The spread comes down to three things: whether we’re welding in place or removing the gate to a bench, how much old metal has to be cut out, and whether the part is a bolt-on OEM bracket or a custom-fabricated plate. A simple LDO bracket swap runs toward the low end. A sagging swing gate that needs hinge reinforcement and a new post plate lands at the top.
Every quote includes the part or steel, the welding consumables, grinding, cleanup, and our labor. The price Nico writes down is the price you pay. If the weld cracks within 365 days, we come back at no charge under the 365-Day Done Right Promise. That’s a written guarantee on every single job, not a verbal one.
| Service | Typical San Antonio Price |
|---|---|
| Replacement bracket, bolt-on (OEM Linear or equivalent) | $220 to $310 |
| Custom-fabricated steel mount or reinforcement plate | $280 to $410 |
| Hinge weld repair with post plate reinforcement | $340 to $480 |
DIY or Call Us?
You can safely check a few things yourself: look for visible cracks at the weld points, check that the operator bolts are tight, and note whether the gate sags with the operator disengaged. What you should not do is attempt welding on a gate that holds a Linear operator in place. Welding near the operator, the control board, or any installed wiring can fry the board instantly. And a gate under tension, especially a swing gate with years of sag, can shift dangerously when a weld is cut. This is not a bolt-on bracket job you finish with a socket set. High heat, heavy steel, and a gate that weighs several hundred pounds are involved.
If you’re seeing any of the symptoms above, call us at (361) 314-4803. Nico will tell you what he thinks over the phone, and if it’s a simple bracket, he’ll probably have the part on the truck when he shows up.
FAQs
A properly fabricated and painted bracket or weld on a Linear gate opener lasts 7 to 12 years in San Antonio, assuming the gate itself is not overloaded or binding. The main factors that shorten that lifespan here are summer heat cycling, which expands and contracts the steel, and the humidity swings that accelerate rust at any pinhole in the paint. Factory brackets tend to fail sooner because they ship with thinner gauge steel.
Yes, a cracked weld on a Linear gate mount can usually be ground out and re-welded rather than replacing the entire bracket, as long as the surrounding metal is still structurally sound. If the crack has propagated far or the metal is thinned from rust, we’ll recommend a new fabricated plate instead. Nico will show you the difference before any cutting starts.
Most Linear welding and fabrication repairs in San Antonio take 60 to 90 minutes on site, not counting setup and cleanup. Removing a gate to reinforce hinge plates on a bench adds time, and a full bench job can run two to three hours. We’ll give you a straight time estimate when we quote the job.
We keep common Linear brackets, mounting plates, and hardware stocked on our service vehicles in San Antonio, covering the LDO, LRA, and older LD and LS series. Custom steel plate work is cut and fit from stock we carry. For unusual or discontinued Linear series, we’ll tell you the lead time before we leave the driveway. We also stock common parts for LiftMaster, Mighty Mule, and Ghost Controls operators.
Call (361) 314-4803 and tell us what your gate is doing. If the price isn’t in writing, it isn’t real, we’ll text it to you before we open the toolbox.
