If your FAAC gate has a cracked weld, a snapped hinge, or a torn mounting bracket, you need fabrication work matched to the exact FAAC model sitting on your property. At Calder Gate Repair Los Angeles, we fabricate and weld FAAC-compatible brackets, hinge assemblies, gate leaf reinforcements, and post mounts, typically installing them for $275 to $1,100 depending on the damage and whether we’re repairing in place or rebuilding a section off-site. Most welding and fabrication calls in Los Angeles are same-day or next-day once we see the damage. The usual story: your gate starts sagging, the opener strains harder each cycle, and eventually the gate leaf gives out at a stress point that’s been weakening for months, sometimes years, in the heat and coastal moisture.
We’re an independent service provider, not a FAAC affiliate or factory shop. That’s actually a good thing when you need welding done, because we’re not trying to sell you a whole new operator. We’ll tell you honestly whether the metal can be saved.
Which FAAC Models This Applies To
FAAC residential and light-commercial swing gate systems in the greater Los Angeles area fall into a few families we see constantly: the 391, 400, 412, 415, 750, 770, S418, S450H, and the newer E024U and C720 lines. The welding and fabrication failures on these systems almost always involve the same handful of components: the gate leaf hinge barrels, the post mounting plates that hold the operator, the articulated arm brackets, and the steel tube or wrought-iron frame sections where the opener mounts.
Here’s the compatibility gotcha that matters in the field: FAAC operators are mounted differently depending on whether you have a pull-to-open or push-to-open configuration, and the mounting plate geometry changes with it. A bracket off a 391 is not a drop-in match for a 415, even though both are FAAC. We take measurements off the existing mount before fabricating: bolt hole spacing, plate thickness, the angle of the arm attachment, and the clearance from the hinge post. If the old bracket is too far gone to measure, we pull the spec from the FAAC installation manual for your model.
On the OEM versus aftermarket question for FAAC welding and fabrication: FAAC doesn’t manufacture most of these welded steel components as standalone items. You’re typically buying a subassembly, like a full mounting kit or an entire leaf, which drives the quote up fast. We source US-made steel plate and tube stock locally in Los Angeles and fabricate to match, often for less than half the factory subassembly cost. For the rare FAAC part that is available as a direct OEM item, like the S450H gate bracket assembly, we’ll price both options and let you choose.
Styles & brands we work with





Signs Your FAAC Welding & Fabrication Is Failing
- Sagging gate leaf that scrapes the ground or the post. This is the most common first sign. The hinge barrel weld has stretched or cracked, letting the gate drop at the outer edge. The opener compensates until it can’t, then it stalls mid-cycle.
- Groaning or popping noise when the gate moves. A cracking weld introduces movement between metal surfaces that were never designed to flex. The noise is the gate frame rubbing against itself and will only get louder as the crack propagates.
- Visible rust bleeding through paint at a joint or bracket. In Los Angeles, coastal moisture from Santa Monica to Long Beach accelerates oxidation at weld seams. What looks like a little rust is frequently a weld that’s lost most of its structural bond underneath.
- Mounting bolts pulling loose from the post or the gate frame. The welded plate or insert they thread into has deformed. Tightening the bolts is a temporary fix; the metal around them is failing.
- Opener faulting out with overload or obstruction codes. A sagging or binding gate makes the FAAC board work harder until it trips a safety. If you replace the board without fixing the underlying metal fatigue, you’ll cook the new board too.

AfterReplacement Cost & What’s Included
Based on what we’re seeing across Los Angeles right now, here’s the honest breakdown for FAAC welding and fabrication work:
- Weld repair in place, no disassembly: $275 to $450. Hinge re-weldment, crack filling, or bracket reinforcement where we can work on-site with the gate still hung.
- Remove, fabricate, and reinstall a mounting bracket: $450 to $750. Includes cutting the old bracket, fabricating a new one to the FAAC spec for your model, and welding it back onto the post or gate frame.
- Full hinge replacement with new fabricated barrels and pins: $750 to $1,100. We remove the gate leaf, cut out the old hinges, build and weld new assemblies, re-hang the gate, and fine-tune the opener limits so the FAAC cycles cleanly.
Every quote includes the written price before we touch a single weld. You’ll know the number before the grinder comes out. The work is covered under our 365-Day Done Right Promise: if the repair fails within a year, we come back at no charge.
What drives the range is mostly the fabrication complexity: simple single-plane plate work is fast; curved or multi-angle brackets take longer. The second driver is whether your gate is steel or wrought iron. Wrought iron welds fine but the old metal often has hidden fatigue cracks nearby, so we budget time to inspect the whole leaf while it’s on the stands.
DIY or Call Us?
Welding a gate back together is not a weekend project, and we’ll be direct about why. The danger isn’t just the arc flash or the hot metal; it’s that a gate leaf that looks fine from the driveway is often under residual torsion from the opener’s travel stops. Release the wrong point first and several hundred pounds of steel can swing free. We’ve seen it happen on hinged gates, especially the big double-leaf driveway models common in Los Angeles hillside homes.
What you can safely check before calling: photograph the damage from several angles, note your FAAC model number from the label on the opener body, and test the gate’s manual release to see if the damage worsens when the gate is free. Then call (213) 322-1415, text us the photos, and we’ll give you a ballpark before we even send a truck. A background-checked Calder tech arrives with a trackable live ETA and a written quote before any work begins.
FAQs
Properly prepped and painted structural welds on a gate leaf typically last 10 to 20 years in Los Angeles, with one caveat: if you live within two to three miles of the ocean, salt air will shorten that to roughly 8 to 12 years unless the weld is primed and sealed aggressively. Call (213) 322-1415 if you suspect coastal corrosion on your gate’s welds.
Often yes, if the surrounding metal is still structurally sound and the crack hasn’t propagated through more than a third of the part. We’ll make that call on-site rather than quoting a replacement sight unseen, and the repair carries the same 365-Day Done Right Promise as a full fabrication.
Most on-site weld repairs are finished in two to three hours. If we need to remove the gate leaf, fabricate new hinges or brackets, and reinstall, the job usually runs a full day. We’ll tell you the time estimate when we quote the price, not after we’ve started.
Both. Our trucks in Los Angeles carry common FAAC mounting plate stock and steel bar. For model-specific components like C720 bracket assemblies that require exact geometry, we fabricate on-site or in the shop from your original part or the FAAC spec sheet. We also stock spare parts for LiftMaster, Mighty Mule, and Ghost Controls for cross-brand gates.
Tell me what it’s doing wrong and I’ll tell you what it actually costs to fix it, before we pick up a tool. If your FAAC gate is sagging, cracking, or making noise, call (213) 322-1415 for a free estimate. A live person answers 24/7, and your quote is in writing before any work starts.
