We stock and install FAAC-compatible welding and fabrication parts across San Antonio, with most installed jobs running $280 to $680 depending on the bracket, hinge assembly, or gate frame section involved. Most FAAC part failures we see are discovered the same way: the gate still opens, but it shudders on the way, sags an inch lower than last month, or makes a metal-on-metal groan that wasn’t there before. We keep the most common FAAC fabrication pieces on our trucks, which means same-day repair is realistic for most San Antonio homeowners.
Here’s how to know if your gate’s problem is actually a welding or fabrication issue, which FAAC models are involved, and what a straight-up honest fix costs.
Which FAAC Models This Applies To
The welding and fabrication work we handle in San Antonio covers the bracket assemblies, hinge points, and gate frame sections tied to FAAC’s 400, 412, 415, 770, and C720 slide operators, plus the 390 and 391 swing-arm series. That’s the bulk of what we see in residential neighborhoods from Alamo Heights to Stone Oak.
The part you need depends on how your gate moves. A slide gate stresses the guide rollers and the operator mounting plate. A swing gate beats up its hinge barrels and the bolt-through points where the FAAC arm attaches to the gate leaf. The quickest way to identify your part is to look at the metal plate on the operator itself: FAAC stamps the model number on the side of the gearbox or on the control board housing. If that label is faded past reading, we measure the arm stroke or the bracket spacing on site and match it from there.
On parts: FAAC’s own fabricated pieces are well-made, but some brackets and hinge weldments have long lead times when ordered through official channels. We’ve had good results with quality aftermarket equivalents on the 400-series slide brackets and the 390 swing-arm weld plates, and we’re straight with you about which option makes sense for your gate. If the OEM part is available locally, we use it. If the aftermarket version is identical in gauge and fit and gets you running three weeks sooner, we tell you that too and let you decide.
Styles & brands we work with
Signs Your FAAC Welding & Fabrication Is Failing
- The gate sags visibly at the free end. This is almost always a hinge barrel that’s worn oval or a weld that’s cracked at the frame corner. The FAAC operator keeps pushing, but the geometry is off, so the motor works harder every cycle.
- You hear a grinding or popping sound when the gate reverses. That’s usually the operator bracket flexing against a cracked weld. The pop is the metal shifting under load and snapping back.
- The gate shudders or jerks mid-travel. A worn guide roller bracket or a misaligned slide track will do this. The FAAC operator is fine; the fabricated track hardware isn’t holding the gate true anymore.
- Rust bleed or flaking paint at the hinge points. In San Antonio’s humidity swings and occasional coastal moisture push, powder coating eventually fails. Once water gets under it, the underlying steel swells and the hinge pin starts binding.
- The gate stops short of the close limit or overshoots it. If the frame has twisted or a weld has let go, the physical dimensions of the gate change. The operator’s limits were set for a gate that no longer exists.
None of these fix themselves. The longer a sagging or twisted gate runs, the harder the FAAC operator works, and operator replacement costs more than bracket repair.
Replacement Cost & What’s Included
For FAAC welding and fabrication in San Antonio, here’s the honest bracket:
- Hinge barrel replacement or rebuild: $120 to $260 installed, depending on gate weight and whether we’re re-sleeving or replacing the barrel outright.
- Slide gate bracket or guide roller assembly: $180 to $340 installed.
- Swing-arm weld plate or operator mounting bracket: $200 to $420 installed, depending on access and how much of the old weld needs to be ground out first.
- Gate frame corner or cracked weld repair: $280 to $680, driven by how much cutting, grinding, and re-welding the frame needs, plus any reinforcement plate we add so it doesn’t crack again in the same spot.
Every price is written down and agreed to before we strike an arc. The number we quote is the number you pay: no discovery fees, no surprise line items. And every welding and fabrication job in San Antonio carries our 365-Day Done Right Promise. If the repair fails within a year, we come back free.

Some things you can check yourself: look for visible rust bleed at the hinge points, push the gate at the free end to see if it moves more than a quarter inch, and snap a photo of the FAAC model plate so we know what we’re working with before we arrive.
But welding on a gate that’s under tension or holding a heavy leaf off the ground is not a weekend project. A gate that falls during a repair can do serious damage to a person, which is why we never work on a propped gate without securing it first. If you’re seeing cracked welds, ovaled hinge barrels, or a twisted frame, call us at (361) 314-4803. We’ll give you a straight price and a time we’ll actually show up.
FAQs
Most FAAC fabrication parts last 8 to 15 years in San Antonio. Gates that face west get the worst of the afternoon heat, and we replace hinge barrels sooner on those than on shaded gates. The original welds themselves usually outlast the powder coating, but once the coating fails, the steel underneath starts moving fast.
Sometimes. A cracked frame corner or a separated bracket can often be re-welded and reinforced with a gusset plate for less than a full replacement. But an ovaled hinge barrel has to be replaced: once the pin hole is no longer round, no amount of welding puts the geometry back. We’ll tell you which situation you have before quoting anything. Call (361) 314-4803 and we’ll walk you through it.
Most hinge and bracket jobs are done in 90 minutes to 3 hours once we’re on site. Frame corner repairs take longer because the gate has to be unweighted, ground clean, welded, and painted, usually 3 to 5 hours. We’ll give you a straight time estimate when we quote the job.
We stock the most common FAAC fabrication items: 400-series slide brackets, 390 swing-arm weld plates, hinge barrels in standard sizes, and guide roller assemblies. If you have something unusual, we’ll source it and tell you the lead time before you spend a dollar.
