FAAC Welding & Fabrication Nationwide

FAAC Welding & Fabrication: The San Antonio Owner’s Guide

We weld and fabricate broken FAAC gate components here in San Antonio, and most jobs run between $280 and $640 installed depending on the part and the damage. If your FAAC swing gate has a cracked hinge bracket, a torn weld at the post mount, or a broken operator arm, we can usually have it fixed the same day we come out. You’ll typically notice it first as a gate that sags, drags, or makes a grinding sound when it cycles.

The honest truth: FAAC builds solid operators, but the metal around them takes a beating in Texas sun and soil. Hinge welds crack. Post brackets fatigue. And when the steel starts to go, the operator keeps pushing, which makes the damage worse. We see it most often on gates installed 8 to 15 years ago in neighborhoods like Stone Oak, Alamo Heights, and Terrell Hills.

Which FAAC Models This Applies To

This work covers the full range of FAAC swing gate systems common in San Antonio: the 400, 412, 415, 750, 770, and 844 series operators, along with the articulated arm kits that pair with them. The welding and fabrication we do is on the gate hardware those operators drive, not the circuit boards inside the control box.

Here’s a compatibility gotcha that saves people money: the FAAC 400-series articulated arm uses a specific mounting plate geometry, while the 750 and 770 series use a longer throw with different pivot spacing. If you have a broken arm or a torn plate, we need to match the bracket hole pattern to your exact operator model before cutting or welding anything. We check the model tag on the operator body first, then measure the existing mount points so the replacement steel lines up without binding the gate.

On the OEM versus aftermarket question for FAAC: original FAAC arms and brackets are built to Italian specs with specific wall thicknesses and pivot bushings. Quality aftermarket steel can match or exceed OEM in raw strength, but the pivot geometry has to be exact or you’ll get binding, premature bushing wear, and a noisy gate within months. For structural welding on posts and hinges, we use locally sourced steel matched to the original thickness. For moving components like arms, we prefer genuine FAAC or verified equivalent parts so the operator doesn’t fight the geometry.

Signs Your FAAC Welding & Fabrication Is Failing

• Gate sags toward the latch side. The top hinge weld or the hinge itself is failing, and the operator is now lifting the gate’s weight instead of just swinging it. You’ll see the gap at the latch post widen first.
• Grinding or popping noise during travel. A cracked weld at the operator mount or a partially separated arm bracket lets the drive unit flex under load. The noise is metal moving against metal where it shouldn’t.
• Operator arm visibly wobbles or shakes. The pivot bushing or the arm’s welded connection at the gate bracket has worn loose. On FAAC 400-series arms, this shows up first as play in the elbow joint.
• Gate stops mid-cycle or reverses unexpectedly. The operator is detecting extra resistance from a dragging hinge or a misaligned post. The electronics are doing what they’re supposed to; the metal isn’t.
• Fresh rust staining under hinge or post plates. Water has penetrated a cracked weld and is corroding from the inside out. In San Antonio’s humid springs and hard rain seasons, a hairline crack becomes structural within one summer.

Replacement Cost & What’s Included

In San Antonio, expect to pay between $280 and $640 for most FAAC welding and fabrication repairs. Here’s how that range breaks down:

• Hinge re-weld or replacement: $180 to $320 per hinge, including grinding back old material and re-aligning the gate
• Post bracket repair or reinforcement: $140 to $280, depending on post condition and steel thickness needed
• Operator arm mount re-fabrication: $220 to $450 for FAAC 400-series arms; 750 and 770 series run toward the upper end
• Full gate alignment after welding: included with every welding job we do

Every welding job includes a written quote before we touch the gate, cleanup of slag and grinding dust, and a check of the operator’s force settings after the metal work is done. The 365-Day Done Right Promise covers every weld and fabricated part we install. If a weld cracks or a fabricated bracket fails within a year of our visit, we come back and make it right at no charge.

DIY or Call Us?

You can safely check a few things yourself: look for visible rust staining around hinge plates and post mounts, listen for grinding during the travel arc, and check whether the gate sags when it’s in the open position. Those observations help us diagnose faster when you call.

What we don’t recommend is breaking out a stick welder and going at a loaded gate hinge yourself. A FAAC operator delivers serious torque, and a cold weld on a load-bearing hinge can let go without warning, taking the gate off its travel path. The gate weighs hundreds of pounds, and the pinch points around posts and the latch area are dangerous for kids and pets. If the metal is cracked, get the gate’s weight off the damaged section before anything else. Call us at (325) 252-5195 and we’ll come take a look. The estimate is free, and you’ll have a written price before any work starts.
