FAAC Welding & Fabrication Nationwide

FAAC Welding & Fabrication: The Corona Owner’s Guide

FAAC welding and fabrication in Corona typically runs $275-$650 installed, depending on whether we’re repairing a cracked gate frame, rebuilding a hinge mount, or fabricating a new bracket from scratch. We stock FAAC-compatible steel, hinge plates, and mounting hardware on our trucks, and most weld repairs are completed in one visit. What usually brings an owner to this page is a gate that’s started to sag, drag, or make a sound like a drawer full of silverware falling down the stairs, which tells us the metal itself has had enough.

The first sign is often subtle: a gate that used to close smooth now catches on the last six inches, or a hinge that looks fine from ten feet away but shows hairline cracks up close. That’s the frame transmitting stress it wasn’t built to carry forever, and Corona’s dry heat plus our hard clay soil only speeds the process up. When a FAAC operator keeps running against a frame that’s out of true, the motor works harder than it should, and that’s when a mechanical problem becomes an electrical one too.

Which FAAC Models This Applies To

Our welding and fabrication work covers the full FAAC residential lineup: the 400, 402, 412, 415, and 770 hydraulic swing operators, along with the S418, S450H, and C720 slide models. The steel we weld is the gate itself and its mounting structure, so the operator model matters less than how the whole assembly was hung in the first place.

Two compatibility checks matter more than the model number. First, FAAC swing arms bolt to the gate through a steel plate, and that plate has to match the arm’s bolt pattern exactly: the 400-series uses a different spacing than the 770, and we’ve seen plates from one drilled out to fit the other, which is how you get a gate that walks itself out of alignment every six weeks. Second, any welded repair on a FAAC gate has to preserve the gate’s weight. Add too much steel and the operator, calibrated for a lighter leaf, starts tripping its own obstruction sensor. That’s the kind of detail that separates a weld that holds from a weld that holds the gate hostage.

On the OEM versus aftermarket question: we use American-made steel plate and channel for structural work, because the material is better. For brackets and hinge mounts, we recommend FAAC’s own stamped steel components where the bolt pattern is proprietary, and quality aftermarket equivalents for simpler plates. We’ll tell you which is which and why, before a torch gets lit.

Signs Your FAAC Welding & Fabrication Is Failing

• The gate leans or sags at the hinge side. The post-side hinge plate is pulling away from the post, either because the welds have cracked or the post itself has started to rot at ground level. Every cycle of the gate works those cracks a little wider.
• A creak or snap when the gate starts moving. That’s a weld failing under load. It sounds like a tree branch breaking underwater, and it won’t go away on its own. By the time you hear it regularly, the weld has already cracked through and the hinge is riding on whatever metal hasn’t let go yet.
• The FAAC operator trips the obstruction alarm more often. The board isn’t failing. The gate is now heavier on one side because the frame has shifted, and the operator’s current sensor is doing exactly what it was designed to do when load changes.
• Fresh rust stains under hinges or weld joints. Corona’s dry air hides corrosion, but a cracked weld lets moisture inside the joint and the rust weeps out. Once rust stains appear at a seam, the crack is already there; the rust just told you about it.
• The gate scrapes the concrete at the latch end. The gate hasn’t grown. The post has moved, or the hinge mount has deformed. A FAAC operator will keep pushing the gate through the scrape, and that fight shortens the life of every part between the motor and the post.

Replacement Cost & What’s Included

In Corona, you should expect FAAC welding and fabrication work to cost between $275 and $650 installed. A single cracked hinge plate that we can cut out and replace runs at the lower end. Rebuilding a gate frame corner or fabricating a custom bracket for a post that’s too far gone to re-weld runs toward the upper end. The price includes the steel, the weld work, grinding and finishing, and re-hanging the gate so it sits true again.

Three things move the number. First is how much of the existing steel is salvageable: rusted-through plate has to be cut away clean before new material can be burned in. Second is post condition; if the post has rotted below grade, we address that because otherwise the new weld is holding onto a sponge. Third is whether the FAAC operator needs recalibration after the gate is re-hung, which we do on the same visit because we service FAAC systems and know the limit settings cold.

Every welding and fabrication job we do carries our 90-Day Done Right Promise in writing. If a weld cracks or the gate goes out of true within 90 days, we come back and fix it. No arguing, no forms, no “well, it’s probably the other side now.” You’ll know the price before we start, and that price doesn’t change when we’re standing in your driveway at the end of the job.

DIY or Call Us?

What you can safely do: check for visible cracks with a flashlight, especially around hinge plates and where the FAAC arm mounts to the gate. Clean off leaves and debris so the gate isn’t pushing through its own compost pile. Note where the gate scrapes or catches, and whether the operator sounds different this week than it did last month. That’s useful information when we talk.

What we don’t recommend touching: anything involving a welder, a grinder, or a gate that’s under tension from its own weight. A sliding gate panel in Corona can weigh 400 to 800 pounds. A swing gate leaf, once the hinges let go, drops exactly where gravity wants it to drop. Welding on a gate that’s still mounted to the operator also risks frying the control board; we isolate the electrical side before we strike an arc, and we test the operator after every structural repair before we call the job done. If the crack is bigger than a thumbnail, call (424) 300-4078 and let us look at it.
