Linear Welding & Fabrication Nationwide | Latch & Post Gate Repair

Linear Welding & Fabrication: The Los Angeles Owner’s Guide

We stock and install Linear-compatible welding and fabrication parts for gate systems across Los Angeles, with most installed repairs running between $180 and $520 depending on the bracket, hinge assembly, or post repair involved. We carry the common Linear gate hardware on our trucks, so a technician can usually assess the problem the same day you call and have the part fitted in one visit. Most owners discover this kind of failure the hard way: the gate starts dragging against the driveway, a weld at the hinge point cracks after years of sun and use, or the operator mounts pull loose from a corroded post and the whole assembly starts to lean.

Which Linear Models This Applies To

Linear gate openers and swing gate hardware appear across a wide range of Los Angeles homes, from older linear-ram swing arms retrofitted onto wrought-iron driveway gates to newer Linear PRO Access (LRA) and Linear Smart Wi-Fi operators paired with steel or aluminum gate frames. The welding and fabrication side matters most on the physical gate hardware itself: hinge brackets, post caps, operator mounting plates, and the steel tabs and ears that Linear operators bolt to. Linear does not make a single universal bracket for every operator generation, so we always confirm the model number off the motor label or the gate post before cutting or welding anything. Some older Linear swing arms use a tabbed mount that sits flat against the post, while newer LRA-series operators use a bolted channel bracket; trying to reuse the old bracket on a new operator usually leaves the arm out of plane, which is how a gate starts to bind within a few months.

Signs Your Linear Welding & Fabrication Is Failing

• The gate sags and scrapes near the latch post. This is almost always a worn or cracked hinge weld on the load-bearing side. In Los Angeles, the dry heat and coastal salt air each do their own kind of damage: inland welds crack from thermal expansion, while Westside welds rust through at the toe.
• The operator mount flexes when the arm moves. The bolts may still be tight, but the steel behind them has fatigued. We see this most often on gates where the original installer welded a thin mounting plate instead of a reinforced tab.
• A hinge or bracket shows a hairline crack through the paint. That crack means the weld underneath has already failed. It will not heal, and it will not hold through another season of gate cycles. The gate needs the bracket cut out and re-welded or replaced.
• The gate makes a metallic popping sound when it starts or stops. That sound is steel moving against steel at a broken weld point. It is not a lubrication problem, and greasing it will not fix the underlying break.
• The post leans after a wind event or a hard push. Once the post base plate or its internal welds let go, the whole gate shifts out of plumb. In clay-heavy Los Angeles soil, a post that was welded to a shallow plate can work loose over just a few years.

Replacement Cost & What’s Included

A straightforward bracket or hinge re-weld on a Linear-equipped gate in Los Angeles typically runs $180 to $340, including grinding, welding, and rust-resistant finish work. Full re-fabrication of a hinge plate or operator mounting tab runs higher, generally $320 to $520 when the old steel has to be cut out and a new piece cut, drilled, and welded in. Re-welding a post that has cracked at the base lands in the same range, though it costs more when the post must be removed from the ground to repair a failed base plate. Before any torch gets lit or any part gets cut, you’ll have the written price in hand, agreed to before work starts. Our welding and fabrication work carries the 365-Day Done Right Promise: if the repair isn’t right, we make it right. No argument, no fine print.

DIY or Call Us?

There is almost no safe DIY path for welding a gate bracket or post. The work involves high heat, molten steel, and grinding sparks around a gate that weighs hundreds of pounds, often under tension from the operator arm. What you can safely do is check the visible hardware: note where the gate drags, look for cracked paint at every weld, and listen for that popping sound during operation. Write down your Linear model number from the motor label before you call. That saves us a trip and helps us bring the right steel and mounting hardware the first time. When the problem involves broken welds, a leaning post, or a mount that flexes under load, call (626) 649-4572 and we’ll schedule a technician who knows Linear gates in Los Angeles.
