Linear Gate Parts & Welding in Arcadia: What to Know First
We provide independent Linear gate parts and welding in Arcadia, and most jobs are done in one visit because we bring a full truck and weld on site. Typical turnaround on a Linear gate repair runs from same day to within 48 hours depending on whether the part needed is on the truck, at a supplier in town, or has to be ordered from Linear. Pricing is straightforward: we quote the job, you approve it, we do the work. The price you hear is the price on the invoice. Call (626) 628-9548 and you’ll get Hal Gatewood or a real person who knows Linear gates, not a phone tree.
This page is for Arcadia homeowners and property managers who own a Linear gate operator or a gate with Linear hardware and need parts, welding, or both. If your gate sags, binds, grinds, or the operator runs but the gate won’t move, the problem is almost always mechanical, and that’s where parts and welding come in. Hal Gatewood has been fixing gates in the San Gabriel Valley since 2001, and he still opens every panel himself. So if the phone rings at 2 a.m., you get a person who has done this for over two decades, not a recorded message.
How Linear Products Fail - and How We Fix Them
- Linear LRA and LSO series swing operators pulling hinge welds loose. Linear swing arm operators push hard against the gate leaf, and on a heavy Arcadia driveway gate, that force lands on the barrel hinges before anything else. We regularly see hinge welds cracked or hinge bolts wallowed out into egg shapes from that constant pressure. The operator didn’t fail. The hinge did. We cut the old hinge off, weld a fresh one in place, and the gate swings quiet again without replacing a thing that didn’t need replacing.
- Slide gate rollers on Linear SL and SLR track systems grinding to a stop. The SLR uses bolt-on steel rollers that ride a V-track, and on a long driveway they collect grit from decomposed granite and the fine dust that blows down from the mountains. That grit chews wheel bearings up fast. Owners often think the Linear motor went weak, but the motor is dragging a gate whose rollers aren’t rolling anymore. We replace rollers and rebuild the track mounts, weld any cracked rail end, and the operator stops overloading. A $40 set of rollers saves a $900 operator.
- Bent or cracked rails on Linear SLR slide gates from wind or impact. Arcadia gets the occasional strong Santa Ana gusts, and a wide gate acts like a sail. The rail takes the twist, and a hairline crack starts at a weld joint. We cut out the cracked section, true the rail back to straight with a level down the full length, and weld in new steel with a full-penetration bead. Then we grind it smooth so the gate rolls over it like it was never touched.
- Latch and receiver plate misalignment after the post moves. This is the classic: the gate opens fine, but the Linear latch won’t catch anymore. It’s not a latch problem. The gate post has shifted in the ground, rotated a degree or two, and now the latch bolt hits the side of the receiver instead of dropping through. We dig and re-set the post in concrete, then align and shim the latch plate so it clicks home again. Fix the post and the latch works. Fix only the latch and you’ll be back out there with the same problem in six months.
- Aftermarket circuit boards and receivers that work, then don’t. Linear operators have been around in several forms long enough that cheap aftermarket boards show up in used machines. Some of them last. Some of them fail in the heat of a San Gabriel Valley August. When we see one acting up, we install a Linear board or a matching receiver that is proven to handle the heat load in a metal cabinet, then test run the gate through thirty cycles in direct sun to make sure it won’t drop out when the afternoon hits.
Our Linear Gate Parts & Welding Process
- 1
We look at the whole gate, not just the part that’s complaining. Hal walks the gate, opens the panel, checks the operator, and puts a level on the post and the rail. When a Linear gate is failing, the root cause is usually a mechanical stress point, and that’s what he finds first.
- 2
We decide with you on the part. If a Linear OEM part is available and makes sense, that’s what we quote. If a quality aftermarket part will do the same job for less without compromising the system, we tell you and let you choose. We never swap in a part that changes the operator’s load or defeats the safety edges.

The repair happens on site. Welding is done in your driveway with the gate in place. We don’t haul it off. We cut, fit, weld, and grind until the repair is smooth and true, and we don’t leave spatter on your concrete or burn marks on your landscaping.
- 4
We run the full cycle test. Open, close, stop, reverse, obstruction, obstruction again. If the Linear operator has a slow-down point, we watch it hit that spot both ways and adjust the limits. The gate gets put through enough cycles in front of you that you can hear and feel the difference.
- 5
You get the 90-Day Done Right Promise, in writing. If something about our work isn’t right, one call brings us back, no runaround. The promise is printed on your invoice. The name is on the shop, and the shop is down the road.

We leave the job cleaner than we found it. No wire clippings, no grinding dust, no mystery bolts left on the ground next to your walkway. If we opened it, we close it.
What Linear Gate Parts & Welding Costs in Arcadia
On most Linear gate jobs, parts are the smaller number on the invoice and labor is the bigger one, because welding done right takes time. A hinge replacement with on-site welding typically runs $180 to $320 depending on the hinge size and whether we need to reinforce the post face. A slide gate roller set replacement is usually $140 to $220 including parts. A cracked rail section weld repair lands around $200 to $380 depending on how much steel needs cutting out. A full post replacement with concrete set and re-hang runs $350 to $650 per post.
- Hinge replacement (welded on site): $180-$320
- Roller set replacement with track alignment: $140-$220
- Cracked rail weld and true: $200-$380
- Post replacement with new concrete footing: $350-$650 per post
- Latch and receiver realignment: $120-$200
What moves the price is gate size, steel thickness, and how much of the surrounding metal is too thin or too corroded to weld against. You’ll always know the number before any work starts. Estimates are free. Call (626) 628-9548 and we’ll give you a real price on the phone, not a range that doubles when the person shows up.
Why Arcadia Homeowners Call Gatewood Fence & Gate for Linear Work
Because the person who answers the phone is the same person who opens the panel. Hal Gatewood has been at this in Arcadia since 2001, and he’s opened enough poorly installed Linear systems to know exactly where the shortcuts hide. He welds on site, he doesn’t sell parts you don’t need, and every job gets a 90-Day Done Right Promise in writing, not “up to” and not “in most cases.” You get $40 off any repair over $200, no trip charge inside the county, a free second opinion on any written estimate, and a permanent 10% discount for seniors and veterans. And if your Linear system is beyond saving, we service LiftMaster, Mighty Mule, Ghost Controls, and DoorKing too, so you never get pushed into a brand you didn’t ask for. As an independent Linear service provider, we’re not tied to a manufacturer’s script, which means we tell you what the gate actually needs, not what makes the most margin.
FAQs
Welding to the hinge post, rail, or gate frame will not void your Linear operator warranty, because the operator is a separate component. We weld to the gate structure, not to the operator cabinet or internals. That said, before we weld, we always disconnect the operator battery and control board leads so no stray current finds its way through the unit, which is exactly what Linear’s own service guidance calls for.
We keep the common Linear wear parts on the truck, including hinges, rollers, latch assemblies, and gate edge sensors, and anything not on the truck is usually at a local supplier within a day. If it’s an older Linear part that has been discontinued, we’ll tell you the honest truth about aftermarket compatibility before you spend a dollar. You never have to order parts yourself and hand them to us, but if you already bought a part, we’ll install it if it’s compatible.
If you call before noon, there is a good chance we’re at your gate the same day. Arcadia is where Hal grew up, not far from the Santa Anita Park side of town, and he still lives about ten minutes from the shop, which means an emergency call isn’t a logistics problem. Call (626) 628-9548 and you’ll get a live person who can tell you right then whether it’s a same-day fix or a next-morning job.
Replace when the rust has eaten through enough of the frame that we’d have to weld in half a new gate anyway, or when the panel is so twisted that it will never rest square on its hinges again. Otherwise, we repair. A gate sags in the hinge post, not in the middle, and that is where we start. Tell me what it is doing and I will tell you what it needs, no runaround.
