Linear Gate Installation in Los Angeles: What to Know First
Linear gate installation in Los Angeles typically runs $1,800 to $5,400 for a complete system, depending on whether you need a new post, concrete work, or power run from the house. We install and service Linear operators as an independent Linear service provider, and most standard installations are finished the same day we start. A live person answers at (877) 610-2993 around the clock, and every quote is agreed upon in writing before we touch anything.
This page is for the homeowner who already owns a Linear opener, or is replacing one, and wants the job done right the first time. We’re Hal Gatewood’s crew at Gatewood Fence & Gate, and we’ve been doing this in Los Angeles since 2001. If you’re looking at a Linear unit in a box or one that’s been acting up since the day it got bolted on, we’ll tell you straight what you’re up against and what it’ll take to fix.
How Linear Products Fail - and How We Fix Them
Linear builds solid operators, but in Los Angeles we see the same handful of issues crop up because of how they’re installed, not how they’re built. Here’s what actually goes wrong:
- Linear LDO series limit switch drift. The LDO50 and LDO33 swing gate operators use a magnetic limit setup that can lose its position over time if the mounting bracket flexes even slightly. What the owner notices is a gate that starts fine in the morning but over-travels by a few inches in the afternoon heat. We don’t just nudge the limits and call it done. We check the bracket for movement, shim or reweld it if needed, then set the limits where they’ll actually hold. Fixing the symptom without the bracket means it drifts again by next month.
- Linear gate operator arm bolt shear on the MegaCode line. The older Linear MegaCode swing arm units used a grade 5 bolt at the arm connection point. On a heavy driveway gate in Burbank or Granada Hills, that bolt shears clean when the gate gets caught by wind or a car bumper. Hal’s seen it happen live. The permanent fix is a grade 8 bolt and a fresh through-sleeve, never just a bolt swap in the old slotted hole. If the hole’s wallowed out, we weld and redrill it so the new bolt has something real to sit against.
- Linear APeX receiver board failure from our summer heat. The Linear APeX line has a receiver board mounted inside the operator housing, and in Los Angeles afternoons - especially in the Valley - that housing bakes in the sun. The board holds up in milder climates, but here we see solder joints fail and remotes start dropping their codes. The fix is board-level repair when possible, or a swapped board with a heat-reflective backing added so the replacement doesn’t cook the same way. Linear’s own manual won’t tell you to do that. Twenty years in this climate does.
- Linear slide gate chain tension and the damn nylon guide wheels. Linear slide gate operators, like the SL series, rely on a chain drive that needs proper sag and regular tensioning against nylon guide wheels. The wheels wear out, the chain starts skipping, and the gate jerks instead of glides. We replace the wheels, set the tension to spec, and the gate runs smooth again. What we’re often undoing is someone else’s “tighten it more” fix, which pulled the chain so tight it killed the gearbox bearings six months early.
- Linear pedestrian gate strike misalignment from soil movement. We don’t just see this in the hills - even flat lots in Westchester shift enough during the year to move a strike plate an eighth of an inch. That eighth of an inch is the difference between a keypad code working and not. We don’t assume the keypad’s bad. We check the strike first, then the wiring, then the board. In that order, every time.
Our Linear Gate Installation Process
When you call us about a Linear gate installation in Los Angeles, here’s how the job goes from first contact to final test:
- 1
Call and talk to a person. You dial (877) 610-2993. Someone answers. We’ll ask what Linear model you have, what the gate’s doing or not doing, and when you want us there. If it’s an emergency, we’ll tell you honestly when we can be on site.
- 2
We come out and look at the whole setup, not just the box. That means the post, the hinges, the gate weight, the power source, the clearance, and how the last person wired it. Hal is the one who sees most of these jobs first, and he’s going to tell you if the post is the problem before he touches the operator.
- 3
We quote parts and labor plainly. OEM Linear parts when the warranty or the job calls for it. Quality aftermarket when it’s the smarter call. You’ll know which is which and why before you spend a dime. The price is agreed before work starts.
- 4
We do the work on site, with the gate in your driveway. That includes welding if needed. We don’t haul your gate to some shop. We fix it where it hangs because that’s where the real measure of the work is.
- 5
We set limits, slowing points, and safety edges to the gate you actually have. Not the gate in some generic install diagram. A gate that weighs 400 pounds and a gate that weighs 900 pounds need different settings, and we test the actual swing and slide under power before we load the tools up.
- 6
You get the 90-Day Done Right Promise in writing. If something’s not right on that Linear install, call and Hal comes back. No run-around, no “we’ll get you scheduled.” That’s the whole point of putting a name on the shop.
What Linear Gate Installation Costs in Los Angeles
Here’s the straight talk on what a Linear gate installation runs in Los Angeles county. These are real numbers from real jobs, not brochure pricing:
- Linear LDO50 swing gate operator install (basic single gate, post already solid): $1,800 - $3,200
- Linear LDO33 compact swing operator install: $1,500 - $2,600
- Linear SL slide gate operator with chain and brackets: $2,800 - $4,400
- Full new driveway gate plus Linear operator, including fabrication and post set: $4,200 - $7,800
- Linear pedestrian gate with keypad and strike: $1,400 - $2,800
What moves the price: the gate’s weight, whether the concrete post needs to be cut out and reset, how far the power run goes, and whether you’ve got a single swing or a double swing with two operators. We’ll give you an exact number before anything starts. No trip charge inside the county, and a free second opinion on any written estimate you’ve already got.
Why Los Angeles Homeowners Call Gatewood Fence & Gate for Linear Work
Because when a Linear gate quits on a Friday afternoon and you can’t get your car out, you don’t want a voicemail. You want the guy whose name is on the shop, and the shop is down the road. Hal Gatewood has been at this in Los Angeles since 2001, and he’s the one who shows up with the truck and the welding rig. Our 90-Day Done Right Promise is stamped in writing on every job, not hinted at in a brochure. We service eight other major brands besides Linear - LiftMaster, Mighty Mule, Ghost Controls, DoorKing, FAAC, BFT, Viking, and Elite - so when you’ve got an older operator and we tell you what’s wrong, we’re not trying to sell you another brand. We’re telling you the truth about yours. Seniors and veterans get 10% off, every job, no haggling, and any repair over $200 knocks $40 off the bill.
FAQs
Linear’s warranty comes from the manufacturer, not from the installer, but we install every unit exactly to Linear’s spec so your warranty stays intact - and if a part fails within our 90-day window, we’re back out to make it right regardless of who manufactured it. We’ll also register the unit for you if it’s a new install.
Most common Linear boards, remotes, and receiver parts are available same-day or next-day from our local supply network around Los Angeles; the less common stuff - like a specific APeX board revision - might take a couple days. If we don’t have it in the truck, we’ll tell you exactly when it lands.
If the housing’s solid, the gearbox runs quiet, and the board’s alive, we’ll repair it every time and tell you so. Replacing a Linear because of a $40 limit switch is exactly the kind of waste we won’t talk you into. If the unit’s genuinely shot, we’ll show you why and give you a straight number for a fresh install.
Same day in most of Los Angeles county, and we answer the phone at 3 a.m. the same way we answer at noon. If it’s an emergency and the gate is trapping your car, tell us on the call and we’ll move the schedule around to get someone to you.
Yes, and that’s one of the jobs we do most often in Los Angeles. The trick is syncing the two operators so the gate doesn’t bind in the middle, and the settings change with temperature. We set the slowing points, test both gates together, and a double swing gets the same 90-day written promise as a single.
To get a free estimate on Linear gate installation in Los Angeles, call (877) 610-2993. Talk to a person, get a square number, and if you don’t like what you hear, we’ll shake on it and part as neighbors.
