We stock and install DoorKing-compatible welding and fabrication parts across Fort Worth, with most weld repairs and bracket fabrications running $180 – $460 installed depending on the component and how much cutting or reinforcing is involved. If the broken part is a common item like a gate hinge bracket or an opener mounting plate, we usually have the piece on the truck or can fabricate a replacement same day. You’ll know you’re in this boat when your DoorKing gate sags on one side, the opener strains and groans, or a weld crack has turned into a full separation that leaves the gate hanging at an angle.

We see this a lot in neighborhoods like Summerfields, Benbrook, and the older subdivisions off Camp Bowie, where steel gates have been swinging for 15 to 20 years and the original welds finally give out. Texas heat and humidity work metal hard, and Fort Worth’s clay soil shifts enough that gate frames flex more than anyone expects. One day the gate works fine. The next, it’s dragging and the opener sounds like it’s fighting for its life.
Quick note on how we operate: Calder Gate Repair Fort Worth is an independent gate repair company, not affiliated with DoorKing. We work on their equipment every week, we know their parts inside and out, and we fabricate what the manufacturer no longer makes. But we’re not a factory service center, and we’ll never pretend to be.
Which DoorKing Models This Applies To
The welding and fabrication work we do spans most DoorKing swing and slide gate operators still running in Fort Worth, including the 9150 and 9100 slide operators, the 6002/6003 swing operators, and the 1601/1602 barrier gate arms. The parts that fail on these units are rarely the circuit boards. They’re the structural pieces: hinge brackets, mounting plates, gate frame connection points, the clevis pins and yokes on swing-arm actuators, and the welded steel posts that hold the whole thing together.
Here’s the compatibility gotcha we run into constantly: DoorKing changed mounting hole spacing on some bracket assemblies between production years, so a bracket that fits a 2008-era 9100 won’t always line up on a 2019 model without modification. We don’t guess. We measure the old part, check the spacing against the unit’s serial number, and fabricate or order the correct piece the first time.
On the OEM-versus-aftermarket question: for cast or machined components like hinges and yoke arms, we prefer genuine DoorKing parts when they’re available because the tolerances are tighter. For weld-on brackets, post reinforcement plates, and custom gate frame repairs, a quality fabricated steel part made locally in Fort Worth holds up just as well, often at 30 to 40 percent less than OEM, because it’s simple thick-gauge steel cut and welded to spec. Nico Alvarez will tell you straight which route makes sense for your specific gate before any work goes forward.
Styles & brands we work with





Signs Your DoorKing Welding & Fabrication Is Failing
- The gate sags or scrapes the ground on the latch end. A weld has cracked at the hinge or the post has shifted, letting the gate drop out of square. The DoorKing opener compensates for a while, then the strain shows up in premature gear wear.
- The opener jerks or bangs when it starts moving. That’s often a broken weld at the opener mounting plate or actuator attachment point. The motor torque hits a loose connection, and you hear it as a knock or thump at the start of each cycle.
- You can see daylight through a joint that used to be solid. A hairline crack opens and closes as the gate cycles. Over weeks, the crack widens into a visible gap, and the gate flexes noticeably while moving.
- The gate stops mid-travel and reverses for no obvious reason. A partially broken weld or bent bracket changes the resistance profile, which reads like an obstruction to the DoorKing’s safety logic. The board trips a reverse before the gate reaches its limit.
- Rust stains streak down from a joint or weld. That’s not cosmetic. Water has gotten into the weld area, the steel is rusting from the inside, and the structural integrity is already compromised. In Fort Worth’s humid summers, this progresses faster than you’d think.
None of these fix themselves. A sagging DoorKing gate only gets heavier on the broken joint, and every cycle makes the weld gap worse.

AfterReplacement Cost & What’s Included
Most DoorKing welding and fabrication repairs in Fort Worth land between $180 and $460 installed. A simple crack repair on a hinge or bracket, ground out and re-welded in place, typically runs $180 – $280. Fabricating and installing a new mounting plate or a custom gate bracket runs $280 – $460 depending on steel thickness, cutting time, and whether we’re reinforcing a post while we’re at it. Full post replacement or major gate frame reconstruction runs higher, and we’ll quote that before anything starts.
Every figure includes the part or fabrication labor, the welding, on-site fitting, cleanup of the old damage, and testing the full gate cycle with your DoorKing opener under load. You get a written price before any work begins, and the number on that sheet is the number on the invoice. The work is covered by our 365-Day Done Right Promise: if the weld fails or the fabricated part breaks within a year, we come back and fix it free.
DIY or Call Us?
You can safely inspect a few things yourself. Look at every visible weld with a flashlight. Push the gate gently by hand and watch where it flexes. Take photos of cracked brackets and the model number plate on your DoorKing. That information helps us quote accurately over the phone.
What you shouldn’t do is fire up a welder on an installed gate. DoorKing gates are heavy, the springs and openers carry stored tension, and a bad weld job on a 700-pound steel gate is worse than no weld at all because it hides the failure until the gate drops or swings into a car or a person. Welding near an installed opener also risks cooking sensitive electronics if you don’t isolate the circuit properly. This is where we earn our keep. Call (682) 432-9830, send us the photos, and we’ll give you a straight answer and a firm price before we touch a single bolt.
FAQs
A properly prepared and welded steel gate joint in Fort Worth typically lasts 10 to 20 years, though factors like irrigation overspray, soil movement, and whether the gate was ever re-squared after a vehicle strike shorten that. We coat and seal every new weld, which matters more in North Texas weather than most people realize. If your gate is nearing year 15 on original welds and you’re hearing groans from the opener, a preemptive inspection beats a midnight emergency. Call (682) 432-9830 and we’ll take a look.
Often, yes. If the crack is clean, the steel hasn’t thinned from rust, and the area isn’t too close to electronics or powder-coated hardware that would melt, a proper weld repair lasts every bit as long as a new part. We’ll tell you honestly if the part is too far gone or too thin to weld safely rather than sell you a patch job, and the price is quoted in writing before we start.
Most single-part weld repairs and fabrications on DoorKing gates in Fort Worth take two to four hours on site, including grinding, welding, cooling, coating, and testing the full open-close cycle under load. If we’re building a custom part at the shop first, that adds a day. When you book, you get a live arrival time you can track, not a four-hour window.
We stock common brackets, hinge mounting plates, and steel stock for fabrication on our trucks, and for DoorKing-specific cast pieces that aren’t common we can usually source them within one to two business days. If your part isn’t on the truck and your gate is down, we’ll fabricate a temporary repair to get you secure while the correct part arrives, and you’ll know the cost of both before we begin.
We stock and fabricate parts for the gate you own, but we also work on LiftMaster, Mighty Mule, and Ghost Controls openers regularly, so if your property has a different brand on another gate or the house next door does, we can handle that too.
If your DoorKing gate is cracked, sagging, or stress-testing the opener, call us at (682) 432-9830. Tell me what it’s doing – or not doing – and I’ll tell you exactly what it needs. We’ll schedule a time, show up when we say we will, and hand you a written price before any work starts.
