FAAC Welding & Fabrication Nationwide

FAAC Welding & Fabrication: The Gardena Owner’s Guide

We stock FAAC-compatible weldments and fabrication parts for the most common 390, 400, 412, and C720 series operators, and most hinge brackets, gate leaf reinforcements, and post plates are installed same-day for between $180 and $420. If you’re in Gardena and a weld has cracked or a mounting ear has sheared off, you’re not alone - the combination of coastal moisture and daily open-close cycles takes a toll on the metal before the motor ever gives out. Most owners discover the failure visually first: a sagging gate leaf, a bracket that has pulled loose from the post, or a hinge pin that now sits at an angle where it used to sit square.

The good news is this is exactly the kind of repair our shop handles in a single trip. Victor Salinas has been matching FAAC hardware to the correct weldment for more than four decades, and we quote the price before any work starts - no surprises on the bill, ever.

Which FAAC Models This Applies To

The welding and fabrication side of FAAC repair covers the steel hardware between the operator and the gate itself, not the circuit boards and limit switches inside the unit. That means the hinge posts, gate leaf frames, operator mounting plates, and the bracket that connects the piston arm to the gate. If you have a FAAC 390, 400, 412, 415, or C720 series swing operator, or an 844 or 884 slide model, this page applies to what holds the gate in place while the motor does its work.

Here is the first Gardena-specific gotcha: many of the FAAC swing gates we see were originally installed in the 1990s and early 2000s, and the original hinge posts were made from a lighter gauge steel than we would weld today. Combine that with thirty years of salt air from the coast, and the metal around the hinge pin fatigues well before the FAAC operator itself shows any wear. Identify the part by measuring the hinge pin diameter, the plate thickness, and the bolt spread - a sharp photo sent to us before the visit lets us stock the right material in the truck.

On the OEM-versus-aftermarket question for FAAC specifically: the actual moving components inside the operator should stay FAAC. The steel brackets, hinge plates, and weldments are a different story. Quality aftermarket steel is often thicker than the original, and we fabricate replacement plates in our shop to match or exceed the factory spec. For a twenty-year-old gate, an upgraded bracket is frequently the smarter fix than an identical replacement.

Signs Your FAAC Welding & Fabrication Is Failing

• The gate leaf sags visibly at the latch end. This almost always means the top hinge is pulling away from the post or the hinge pin has worn the plate into an oval. The FAAC operator is still pushing fine - the steel around the hinge has simply given up.
• The operator bracket wobbles when the gate moves. The mounting bolts may be tight, but the plate itself has cracked around the weld or the bolt holes have elongated from torque stress. You will see the movement if you watch the bracket while someone cycles the gate.
• You hear a metal-on-metal pop or creak at one specific point in the travel. That is a cracked weld flexing under load. Each cycle works the crack wider, and a gate that pops today can drop tomorrow.
• The gate post itself leans or shifts. In Gardena, this is more common than people expect. The soil under a concrete post footer settles over decades, and the first sign is a gate that no longer lines up with the strike plate the way it did last year.
• Rust staining runs down from the hinge area or weld seams. Surface rust you can wire-brush. Deep flaking rust on a load-bearing weld is a failure in progress, and it is the one symptom we tell homeowners not to wait on.

Replacement Cost & What’s Included

For a typical FAAC gate in Gardena, here is what to budget:

• Hinge bracket replacement or re-weld (per hinge): $120 - $240 installed
• Operator mounting plate replacement: $140 - $260 installed
• Gate leaf reinforcement and re-alignment: $200 - $420 installed
• Hinge pin replacement (stainless steel, incl. labor): $80 - $180 per pin
• Full hinge set replacement on a standard single swing gate: $340 - $580 installed

The range depends on two things: how much clean fabrication we can do on site versus how much has to return to the shop for a proper weld, and whether your post is reusable or needs to be cut back and re-set. Every price is quoted and agreed before any work begins - that is non-negotiable for us. The work is covered by the 90-Day Done Right Promise, in writing, so if a weld settles or a bracket shifts, we come back and make it right.

DIY or Call Us?

There are two things an owner can safely check before picking up the phone. First, look at the hinge area with a flashlight and note whether any bolt heads are sitting proud of the plate, any cracks are visible, or rust has flaked to bare metal. Second, have someone cycle the gate while you watch the operator mounting bracket - if it flexes, you have your answer. That is where the safe part ends.

A gate leaf carries hundreds of pounds, and when a hinge weld fails, it fails fast and without warning. A falling gate can kill. We do not recommend grinding, cutting, or welding anything on a loaded gate assembly unless you have the stands, the clamps, and the experience to support the leaf while you work. The springs and cables on some FAAC installations are under tension even when the gate is open, and releasing them incorrectly is a serious injury waiting to happen. This is the part of the job where the right call is a phone call: (916) 398-2696.
