FAAC Welding & Fabrication in Chicago, IL

FAAC Welding & Fabrication: The Chicago Owner’s Guide

FAAC welding and fabrication repair in Chicago typically runs $340-$780 installed, depending on gate size and material, and we stock FAAC-compatible brackets, hinge assemblies, and custom weldments for same-day service on most calls. Most homeowners discover the problem when their gate starts sagging, grinding, or the FAAC operator strains to push a frame that has warped or cracked at the weld.

Call (844) 321-0766

We’ve been called out to Lincoln Park homes where a wrought-iron gate has slowly torqued itself out of square over fifteen Chicago winters, and to Oak Park estates where the original fabricator used mild steel where 316 stainless belonged. If the gate is giving you trouble, tell me what it is doing and I will tell you what it needs.

Which FAAC Models This Applies To

FAAC operators from the 400 series through the 770, plus the S418 and S800 hydraulic swing-gate lines, all depend on fabrication that is square, level, and matched to the motor’s torque curve. The critical detail most people miss: FAAC’s Italian-spec mounting plates use metric bolt patterns, and many Chicago gates were originally fabricated for domestic operators with imperial spacing. We keep adapter plates and custom-drilled brackets on the truck because we’ve run into this mismatch too many times in Ravenswood and Beverly.

To identify your exact setup, check the FAAC label on the motor housing for the series number, then measure your gate frame’s wall thickness and the post-to-post clear span. For the 400 series, FAAC specifies a minimum 3-millimeter wall box-section or equivalent; anything thinner and the operator will eventually tear the mount loose. We fabricate to those specs, not guess. We are an independent service provider, not affiliated with FAAC, which means we source both OEM FAAC hardware and quality aftermarket equivalents when the OEM part is back-ordered from Italy. For a gate that sees daily use in Chicago’s freeze-thaw cycle, we often recommend domestic 304 or 316 stainless over standard FAAC mild-steel brackets - the upfront cost is higher, but the lifespan doubles.

Signs Your FAAC Welding & Fabrication Is Failing

• The gate drags or scrapes the driveway. This usually means the hinge-side post has cracked at the weld or the underground box has rusted through and settled. In Chicago, the salt load from winter road treatment accelerates corrosion at the base of iron posts - we see this most in lakefront neighborhoods where the spray carries.
• The FAAC operator runs but the gate barely moves. The motor is healthy, but the frame is racked or a weld has failed, converting linear push into twist instead of swing. We diagnosed this exact failure last month on a sixteen-foot aluminum gate in Portage Park where the original fabricator had skipped the internal gusset plates.
• You hear metal-on-metal grinding at the hinge. The pin has worn oval or the barrel hinge has split its weld. On heavy wrought-iron gates, this progresses fast once it starts - the pin chews the barrel, and then you’re replacing both plus the surrounding frame.
• The gate has visible cracks at weld joints, especially at the corners. Thermal cycling in Chicago - from twenty below to ninety-five humid degrees - stresses aluminum and steel differently. Aluminum gates in particular develop fatigue cracks at the heat-affected zone; we cut out the old weld, preheat properly, and re-weld with 4043 or 5356 filler depending on the alloy.
• The gate leans or the latch no longer meets the strike plate. Either the post has rotated in its footing or the frame itself has twisted. We check plumb with a laser level, then determine if the fix is re-welding the post bracket or pouring a new concrete pier.

Replacement Cost & What’s Included

What drives the range: material type (mild steel vs. stainless vs. aluminum), access difficulty, and whether we can work the gate in place or need to remove it to the shop. We settle the full price before we strike an arc - no surprises on the bill. Every weld is covered by our 90-Day Done Right Promise, the Keystone Standard: if it cracks, if it shifts, if it is not right, we come back and make it right with no paperwork and no arguing.

Active offers: $50 off any repair over $250, free second opinion on any written estimate, $89 seasonal tune-up, and a standing 5% senior and veteran discount.

DIY or Call Us?

There is a short list of things a careful homeowner can check safely. Verify that the FAAC operator’s mounting bolts are tight. Look for obvious cracks in paint or rust streaks that indicate a hidden weld failure. Listen for whether the noise comes from the motor or the gate itself - that tells you which system is asking for help.

Where DIY goes wrong: cutting or grinding on a loaded gate frame is dangerous work. A sixteen-foot wrought-iron gate can weigh four hundred pounds, and if the temporary support fails while you are under it, the injury is severe. Welding on gate automation also risks damaging the FAAC control board with stray current if grounds are not isolated properly - we have replaced boards that were fried by well-meaning handymen. For anything involving structural repair, electrical isolation, or overhead work, we recommend a trained technician. Call (844) 321-0766 and we will walk through what you are seeing; if it sounds like a job for the truck, we will give you a straight timeframe and price.
