DoorKing welding and fabrication in San Francisco typically runs $340 to $880 installed, depending on whether we’re repairing a cracked gate frame, reforging a broken hinge mount, or fabricating a new bracket to match your operator. Most jobs are completed same-day or next-day because our trucks carry steel stock, welders, and the common DoorKing mounting plates. You’ll usually discover the need for this work the hard way: the gate sags on one corner, a weld pops with a sound like a gunshot, or the operator strains against a frame that’s no longer square.

We’re an independent San Francisco gate repair company, not a DoorKing dealer. That independence matters here because it means we stock genuine DoorKing parts alongside quality aftermarket equivalents, and we choose whichever makes more sense for your gate’s age, metal condition, and how long you plan to stay in the house. Cody Beckman and our crew have re-welded enough DoorKing frames across San Francisco to know which repairs hold and which ones come back in eighteen months.

- What we fix: cracked frames, broken welds, bent hinge plates, operator mounts, gate leaf sag
- Same-day: available for most weld repairs; fabrication jobs often next-day
- What’s included: parts or fabricated steel, labor, cleanup, and our 365-Day Done Right Promise
Which DoorKing Models This Applies To
DoorKing gate operators and their matching gates come in a few families, and the fabrication needs differ by frame metal and hinge design. The most common in San Francisco are the 9000-series slide operators (often paired with chain-link or tube-steel sliding gates), the 6000-series swing operators (usually on ornamental iron or aluminum gates), and the MicroCLIK and MicroPLUS lines on lighter residential gates. Each puts different stress on the weld points, and each fails in its own way.
Before we weld anything, we check the operator plate on the side of the unit. DoorKing stamps model and serial numbers there, along with voltage and cycle ratings. For the gate itself, we measure the wall thickness of the steel tubing at the point of failure, because a gate built from 14-gauge steel needs a different approach than one built from 16-gauge ornamental iron. That difference is the number one reason a weld fails again: someone burns through thin metal with settings meant for thick stock. For DoorKing gates specifically, aftermarket hinge brackets and roller plates are usually fine when they’re made from the same gauge and coated for coastal air. For the operator mounting arms and drive rail connections, we almost always recommend genuine DoorKing parts because the bolt-hole patterns and tolerance stack don’t match up reliably with generic pieces.
Styles & brands we work with





Signs Your DoorKing Welding & Fabrication Is Failing
- The gate sags visibly at the latch end. This usually means a hinge weld or hinge-to-post connection has cracked, and the gate is now hanging its full weight on one good hinge. The operator keeps working harder to compensate, which shortens its life.
- You hear a creak or groan that’s getting worse during opening and closing. That’s metal fatigue working through a partially failed weld. San Francisco’s fog and salt air accelerate this, especially on gates within a few miles of the ocean.
- The operator mount moves or flexes when the motor runs. DoorKing operators transfer all their torque through the mounting bolts. A loose or cracked mount means those bolts are now working against egged-out holes and cracked plate steel.
- You can see orange rust staining below a weld joint. Rust streaks are the tell that water has gotten under a cracked weld. In San Francisco’s wet winters, that crack grows every time the temperature swings.
- The gate has started hitting the stop or bottoming out at a different point than before. Something shifted. Often it’s a broken weld at the drive rail connection or a bent steel upright, and the operator limit switches can no longer reliably stop the gate where they should.

AfterReplacement Cost & What’s Included
For San Francisco homeowners, a straightforward weld repair on a DoorKing gate typically lands between $340 and $520. That covers cutting out the failed section or cleaning the cracked joint, re-welding with proper penetration, grinding smooth, and priming the repair. A fuller fabrication job – say, replacing a rusted-out bottom rail or building a new operator mounting bracket from plate steel – runs $550 to $880. The price spread comes down to steel thickness, access, and whether we’re repairing in place or pulling the gate off its hinges to work on saw horses.
Every quote is written before we strike an arc. You’ll see the exact number, and we don’t start until you say go. That price includes cleanup: we lay drop cloths under our work area and sweep up grinding dust before we leave. The repair is covered by the 365-Day Done Right Promise, which means if the weld fails or the fabrication doesn’t hold, we come back and make it right. No argument, no fine print.
DIY or Call Us?
You can safely do the inspection. Look for cracked paint, rust streaks, and any visible gap where two pieces of steel should be touching. You can also rock the gate gently by hand with the operator disengaged to feel for slop in the hinges. What you should not do is attempt the weld yourself unless you’re a trained welder with proper gear. Gate frames are under tension even at rest, and a bad weld on a hinge can fail catastrophically while the gate is swinging. That’s a multi-hundred-pound steel panel. The risk isn’t theoretical.
Beyond safety, the practical issue is that a repair weld on a load-bearing joint needs to be bored out, beveled, and welded hot enough to penetrate, not just lay on top. That’s the difference between a fix that lasts ten years and one that cracks again in four months. Call (628) 227-2771 and we’ll come look – the estimate is free, and you’ll have a straight answer before you spend anything.
FAQs
A properly done weld repair on a DoorKing gate in San Francisco typically lasts 10 to 15 years, assuming the gate was prepped correctly and primed against salt air and fog moisture. Coastal homes within a few blocks of the ocean will see shorter spans because that marine layer accelerates corrosion at every joint and scratch.
We can tell you after inspection what a realistic expectation is for your specific gate – call (628) 227-2771 and we’ll walk the gate with you.
Most cracked steel gate frames can be repaired by welding, as long as the surrounding metal is still sound and the crack hasn’t spread through more than a third of the structural member. When rust has thinned the tubing wall below about 50 percent of original thickness, we recommend replacing that section of steel instead.
If you’re not sure which situation you’re in, call (628) 227-2771 – we’ll measure the steel and tell you straight what’s repairable.
A typical weld repair on a DoorKing gate takes 2 to 4 hours from setup through cleanup, including grinding, welding, and primer. A full fabrication job – a new bottom rail or rebuilt operator mount – usually runs 4 to 8 hours and sometimes needs an overnight for paint to cure before the gate goes back into service.

Yes. Our San Francisco trucks carry common DoorKing bracket plates, hinge plates, tube steel in multiple gauges, flat bar, and angle stock, plus the consumables we need for the weld itself. For less common fabricated pieces, we source them same-day from local Bay Area steel suppliers and weld them to spec in the field.
