FAAC Welding & Fabrication Nationwide

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

FAAC welding and fabrication in San Fernando typically runs $275 to $850 installed, depending on whether we’re repairing a cracked hinge bracket, rebuilding a bent gate frame section, or fabricating a custom mounting plate for your operator. We stock FAAC-compatible steel, mounting hardware, and weld-ready brackets on our trucks, and most repair jobs are done same-day. We’re an independent gate specialist, not affiliated with FAAC, but we’ve been welding and fabricating for their swing and slide operators across the San Fernando Valley for over four decades.

Here’s how most owners discover the problem: the gate starts to sag, or the operator pushes with more effort than it should, or there’s a creak that wasn’t there last month. By the time you see a visible crack in a hinge or bracket, the metal has usually been failing for months.

Which FAAC Models This Applies To

We fabricate and weld for the full FAAC residential line: the 390, 391, 400, 412, 415, and 770 swing operators, plus the 741, 844, and S418 slide units. The compatibility gotcha that trips up most homeowners is this: FAAC hinge brackets and mounting plates are metric, and the bolt spacing changed between the older 390/391 series and the newer 400-series releases. A bracket that looks identical from across the driveway will be off by a few millimeters when you line it up. If you don’t know your model, grab a photo of the silver serial tag on the operator housing, or measure the bolt centers on the bracket itself. We match that on the spot.

On the OEM-versus-aftermarket question for FAAC specifically: the factory hinge brackets are fine steel, but in San Fernando’s dry heat and hard water, we see the original mounting hardware seize and corrode sooner than the bracket itself. When we fabricate a replacement, we’re usually improving on the original geometry, not just copying it. A quality fabricated bracket with powder coat will outlast the factory part on the next cycle. We’ll still install OEM when the customer asks. The honest answer is that for FAAC mounting hardware, a well-built local fabrication is often the smarter money.

Signs Your FAAC Welding & Fabrication Is Failing

• The gate sags toward the latch side. This is almost always a hinge or hinge-post bracket that has cracked at the weld or pulled at the mounting bolts. The operator is now lifting the gate’s weight every cycle, not just pushing it.
• You hear a pop or ping when the gate opens or closes. That’s the sound of stressed metal shifting, usually a crack in the operator mounting plate or the gate frame itself flexing under load.
• The operator struggles, then stops mid-travel. The motor may be fine, but a bent or broken bracket misaligns the piston with the gate leaf, creating binding that burns out FAAC motors faster than anything else we see.
• Visible rust blooms at a weld joint or bolt hole. Rust at a joint means moisture has been working into the metal. In San Fernando, where mornings bring coastal dampness and afternoons bring heat, that cycle eats welds faster than owners expect.
• The gate’s travel path is uneven or it scrapes the driveway. This points to frame fatigue, often where the bottom rail meets the hinge stile. Fabrication work on the frame, not just the bracket, is usually the permanent fix.

Replacement Cost & What’s Included

Here’s the straight math for San Fernando. A simple FAAC hinge bracket removal and weld-in replacement runs $275 to $400. A custom-fabricated operator mounting plate for a 390 or 412-series unit runs $400 to $600. Full gate-frame repair, where we cut out the failed section and weld in new steel, runs $600 to $850. The price you’re quoted is the price you pay: parts, labor, weld time, grinding, and paint or powder coating are all in that number, and we settle it with you before a single bolt is turned.

Every FAAC fabrication job carries our 90-Day Done Right Promise in writing. If that weld cracks or the bracket shifts after we leave, we come back and make it right. No paperwork, no arguing. Victor Salinas has been standing behind metalwork in San Fernando since 1984, and that’s why half his customers wave from the driveway instead of calling a new company every few years.

DIY or Call Us?

You can safely do the diagnosis yourself. Grab the gate leaf and try to lift it vertically, if there’s play at the hinge, you’ve found the problem. Inspect the bracket bolts and look for dark lines radiating from any weld joint. That’s the cracking pattern that precedes a failure, and it’s visible to the naked eye months before the part gives out.

Here’s where DIY goes wrong, and I’ll be blunt about it: a FAAC swing gate under power can weigh 400 pounds or more, and the operator is applying hydraulic force to the same bracket you’d be unbolting. If that gate shifts while the bracket is loose, or if you’re under it when the last bolt comes out, you’re not walking that one off. Welding the new bracket in place also requires the gate to be plumb and square in three planes before the first bead goes down. Get the geometry wrong by a half degree, and the operator binds, the motor overheats, and you’re buying a $1,200 replacement in six months. This is not the job to learn on. Call us at (925) 307-8328 and we’ll have a truck in front of your house, with the right steel and the right welder, usually the same day you call.
