FAAC Welding & Fabrication Nationwide

FAAC Welding & Fabrication: The Katy Owner’s Guide

FAAC welding and fabrication work in Katy typically runs between $350 and $1,400 installed, depending on whether we’re repairing a cracked gate frame, rebuilding a hinge mount, or fabricating a replacement bracket for a FAAC 400, 412, 415, or 770 operator. Most jobs are completed same day once we have the gate on the bench or the truck set up on site. What owners usually notice first is a sag at the latch side, a gate that scrapes the driveway in the afternoon heat, or a crack running through a weld point where the operator arm connects to the gate leaf.

We’re an independent service provider, not a FAAC factory shop, and that matters here: we see enough failed welds on Katy gates to know exactly which joints take the most abuse in this climate. A gate that swings forty times a day in Houston-area heat and humidity stresses the same points every single cycle. When those points are welded thin or patched poorly on a previous repair, they fail again, usually in the same place.

Which FAAC Models This Applies To

This work covers the FAAC hydraulic and electromechanical swing-gate line most common in Katy subdivisions: the 400, 402, 412, 415, and the heavier 770 series. The 750 and 760 underground operators present different welding and fabrication needs because the hinge geometry and the lower pivot point carry the load differently than an above-ground arm setup.

Here’s the compatibility detail most owners miss: FAAC 400-series operators use a two-piece articulated arm, and the clevis pin at the second knuckle is often the first metal component to fail due to lateral play. The 412 and 415 add a release handle that spans thicker on the housing, which changes how we cut and weld a replacement bracket. The 770 operates at a slower travel speed but delivers more torque, so we fabricate reinforcement differently for that model. When we arrive, we photograph the operator label, measure the arm mount centers, and confirm the series before any cutting starts. That’s a documented measurement, not an eyeball guess.

On the OEM-versus-aftermarket question: FAAC factory brackets and hinge weld plates are built to specification, and we install them whenever the part is available and the damage is limited to a known bracket. But for repetitive weld failures on the same gate, we often fabricate a slightly heavier gauge replacement at the shop using materials rated for Texas sun and weather exposure. The decision is made on site, explained before work begins, and priced in writing.

Signs Your FAAC Welding & Fabrication Is Failing

• Sag at the latch corner: When a gate leaf drops a quarter inch or more at the free end, the hinge-side weld or the bottom hinge plate is typically stretching or cracking. On FAAC 400 operators, this happens fastest when the operator arm pushes against a distorted hinge rather than through a clean arc.
• Operator arm rattles at the clevis: The steel pin wears oval over time, which creates play that shows up as a rattle or a small jerk on startup. If left alone, that slop widens the hole in the arm and turns a simple pin swap into a fabrication job.
• Cracked weld at the post mounting plate: Katy’s black clay soil expands and contracts through the seasons, and the post base plate takes the brunt of that movement. We see hairline cracks radiating from the post weld on gates that were installed without enough foot depth for the soil conditions.
• Gate scrapes the driveway only in late afternoon: Heat expansion is rarely the sole culprit. What we find more often is a failing weld near the bottom hinge that drops the leaf by a few millimeters when the leaf is hot enough to flex.
• Remote opens the motor but the gate barely moves: The operator is trying to push against a bound hinge, a cracked frame section, or a seized post bracket. The motor is healthy; the fabricated metal around it is not.

Replacement Cost & What’s Included

Most FAAC welding and fabrication work we handle in Katy lands between $350 and $1,400 installed. A typical hinge mount repair with on-site welding runs $350 to $600. Reinforcing a cracked frame section or rebuilding a post base plate falls between $500 and $900. Full custom fabrication, like a new operator arm bracket or a reworked gate frame section for a 770, runs from $900 up to $1,400 depending on material, thickness, and finish work.

The written price you get before any work starts includes materials, the fabrication time, on-site welding, grinding and cleanup, and the photo documentation afterward. We don’t separate labor from parts into an hourly meter you can’t predict. The price is a flat number, agreed before the first weld, under Haven Standard Clause 1. Every FAAC welding job we complete is covered by the 365-Day Done Right Promise: if the weld fails or the bracket we fabricated gives way within a year, we return and make it right at no charge.

DIY or Call Us?

Welding on a FAAC gate is not a weekend project unless you already own a MIG or TIG rig and know how to control heat distortion on thin steel. The force path is the problem: a gate leaf with a FAAC 400 or 770 attached to it is a moving structural load, and a poorly penetrated weld concentrates stress in one spot. When that spot fails, it fails suddenly, and a gate that weighs 300 to 700 pounds can do real harm to a person, a vehicle, or the operator itself.

What an owner can safely check is measurements. Measure the gap between the gate leaf and the post at the top and bottom hinge, measure how far the latch corner drops between morning and late afternoon, and send us those numbers along with a few photos. We’ll tell you over the phone whether this looks like a clean hinge adjustment or a real fabrication job. If it’s the latter, call us at (346) 818-3319 and Adrian Vance will come out, measure everything, and hand you a written price before any metal gets cut.
