AfterFAAC Welding & Fabrication: The Chatsworth Owner’s Guide
We stock and install FAAC-compatible welded components and fabrication work across Chatsworth, with most bracket, hinge, and mounting repairs running $220-$480 installed depending on the part and your gate’s weight. Same-day service is available for most weld failures when we have the component on the truck, which covers the bulk of common FAAC swing-arm and ram-mount breaks. The typical discovery goes like this: the gate starts lagging on one side, then you notice a crack near the mounting plate, then one morning it simply won’t move and the motor is straining against a bracket that’s no longer attached to anything structural.
Which FAAC Models This Applies To
The welding and fabrication work we do covers FAAC swing-gate operators in the 400, 412, 415, 770, and S418 series, plus the 390 and 391 rams used on larger estate gates. The compatibility gotcha most owners miss: the mounting plates and pin brackets on a 412 are not interchangeable with the 415, even though the arms look nearly identical sitting on a shelf. The bolt-hole spacing differs by 8 millimeters, and forcing a 415 plate onto a 412 post will oval the holes and crack the plate within a season or two. Before you order anything, check the data plate on the operator body itself. It carries a four-digit model code and a serial number, and that serial ties to the specific bracket revision FAAC shipped with that unit. For OEM versus aftermarket: FAAC-branded mounting hardware runs heavier-gauge steel than most aftermarket equivalents, and in Chatsworth’s sun-and-salt air, the OEM powder coat holds up measurably longer. We’ll recommend aftermarket only where it matches or exceeds the original spec, usually for non-structural spacers and shims, never for load-bearing brackets.
Signs Your FAAC Welding & Fabrication Is Failing
- Gate sags on the hinge side while closed. The weld at the bottom hinge bracket has begun to tear. It rarely fails all at once. You’ll see a hairline crack forming at the top edge of the weld bead long before the gate drops.
- Motor runs but the gate moves in jerks. A cracked mounting plate flexes under load, changing the operator’s geometry by a few degrees each cycle. The motor compensates, then overcorrects, and the gate stutters through its travel.
- New squeak or groan that changes pitch as the gate moves. Metal-on-metal friction where a weld has separated. The sound is the two faces rubbing under tension, and it will get worse, not seat itself.
- Visible rust weeping from a weld joint. In Chatsworth’s marine-influenced air, a compromised weld draws moisture into the seam. The orange stain is the first indication the joint is failing from the inside out.
- Gate stops mid-travel and the FAAC controller shows an obstruction fault. The operator’s force sensor is reading the added resistance from a flexing bracket and shutting the cycle down as a safety stop. The part that failed is mechanical, not electronic.
BeforeAfterReplacement Cost & What’s Included
In Chatsworth, expect $220-$340 for a single hinge or bracket re-weld including grinding, prep, and a primer-plus-topcoat finish matched to your gate. Full mounting plate replacement on a FAAC 412 or 415 runs $340-$480 when we need to cut out the old plate, fabricate and drill a new one, weld it in place, and re-anchor the operator. The price is written and handed to you before any work starts, and it includes the part, the labor, the finish work, and a photo record of every weld before and after. We don’t quote by the hour on this kind of repair; you get a flat price for the completed job, and if we find additional structural damage while we’re in there, we stop, show you what we found, and quote the addition before touching it. All welding work carries our 365-Day Done Right Promise: if the joint, the alignment, or the finish fails within a year, we fix it at no charge, no question.
DIY or Call Us?
You can inspect the welds yourself. Look for hairline cracks, rust weeping, or daylight through a joint that should be solid. What you shouldn’t do is attempt the fix. Gate brackets and mounting plates sit under spring tension and the weight of the gate itself, and a weld that fails under load turns a 400-pound gate into a falling object. High-tension hardware and load-bearing fabrication on a moving gate need a trained technician with the right equipment and an understanding of how the weld failure changes the operator’s travel geometry. If you’ve spotted the crack and want a second set of eyes before you commit to the repair, call us at (661) 495-2023. We’ll match the part, quote the job in writing, and fix it clean.
FAQs
OEM FAAC mounting brackets on a properly aligned gate typically last 8-12 years in Chatsworth, with the failure point usually the weld at the post side, not the bracket itself. Aftermarket brackets run 4-7 years in the same conditions. If yours failed inside five years, the cause is almost always gate misalignment putting constant lateral load on the joint. Call (661) 495-2023 and we’ll tell you whether the bracket or the alignment is the real problem, with the repair priced in writing either way.
Yes, in about 60 percent of cases. A single clean crack in a bracket with intact surrounding steel is a straightforward re-weld, clean, and refinish. If the plate is rusted through, warped, or already re-welded once before, replacement is the honest fix and usually cheaper than two more repairs. We’ll show you the crack under load, explain which path we’d take, and you’ll have the price before we pick up a torch.
Most hinge and bracket re-welds are done in 2-3 hours on site, including grinding, welding, cooling, and finish coating. Full mounting plate fabrication and replacement takes 4-5 hours because we build the plate on site to match your operator’s bolt pattern exactly. We’ll give you the time estimate with the written quote before any work starts.
We carry common FAAC 412 and 415 mounting plates, hinge brackets, pin kits, and a range of raw steel stock for custom fabrication on most service trucks serving Chatsworth. If your part is unusual or series-specific, we order it and typically have it installed within two to four business days. Either way, you get a written price before the work begins, not after.
