Linear gate installation in Los Angeles typically runs $1,400 to $4,800 for a complete residential system, depending on whether you need a swing or slide operator, new gate fabrication, or just the operator and controls mounted to an existing gate. Most single-operator installations are completed in one day, though a full gate plus operator job usually takes two to three days start to finish. The honest posture is simple: you get a written price before we touch a bolt, and that price does not change unless we find something genuinely hidden that we show you and agree on together. If you own a Linear operator and need it installed or replaced, call us at (213) 322-0062 and tell us what you’re working with.
How Linear Products Fail – and How We Fix Them
- Linear LDO50 swing arms losing travel mid-cycle. The LDO50 is a workhorse in Los Angeles hillside driveways, but the internal limit cams wear unevenly when the gate is slightly over-traveled against a warped post. We see it in Silver Lake and Echo Park constantly. The fix is a limit cam replacement and a hard stop adjustment so the arm never fights the post again. Chasing it with a new arm without fixing the stop means you’ll be back in six months.
- Linear sliding gate operators with burned-out run capacitors. The SL and SLD series slide operators pull hard on startup, and Los Angeles heat plus a gate that’s even slightly out of roller alignment makes the capacitor work double time. Symptom: the gate hums but doesn’t move, or trips the breaker on hot afternoons. We replace the capacitor and dial the clutch so the operator isn’t fighting friction it shouldn’t have to.
- Linear keypad and radio receiver interference in dense LA neighborhoods. Linear’s multi-code receivers are generally solid, but in areas like West Adams or Koreatown where every house has a different remote, a receiver set to all-code mode picks up neighbor signals. Homeowners report gates opening on their own. We lock the receiver to a specific code and walk the perimeter to rule out a stuck loop detector. It’s a twenty-minute fix that most companies misdiagnose as a bad board.
- Linear actuator arms on double gates falling out of sync. When you have two LDO50 or older Linear 1000-series arms on a double swing gate, one arm drifts ahead and the gate binds hard against the center stop. The cause is usually voltage drop on the second arm’s run. We pull a dedicated circuit or upsize the control wiring, then re-sync both arms so the leafs close like book covers, not a train wreck.
- Linear solar panel kits that cannot keep up with LA marine layer days. Linear sells a nice solar retrofit, but a week of June gloom in Playa del Rey or the Westside leaves the battery too weak to cycle the gate. The operator faults out and the owner thinks the board died. We test the panel output, upgrade the battery to a deep-cycle unit that handles partial charge days, and set the operator to sleep mode when idle. It’s the difference between a gate that works at 7am and one that won’t budge until noon.

Our Linear Gate Installation Process
- 1
We talk it through by phone. You tell us what gate you have, what Linear operator is on it or waiting to be installed, and what it’s doing or not doing. We give you a ballpark number before we hang up.
- 2
We come out and measure everything. Gate weight, hinge condition, post plumb, power availability, vehicle clearance, and sun exposure all go into the written quote. We do not skip this step, because a guess at this stage is how a ol,800 quote becomes a $3,200 invoice at the door.
- 3
We give you a written price. The Kingswell Guarantee means the number is on paper before a single tool comes off the truck. No “we’ll figure it out as we go” pricing. It includes the operator, any mounting hardware, electrical connection work, and programming.
- 4
We do the install. Depending on the job, this means mounting the operator, pulling the power run, setting limits, programming remotes, keypads, and vehicle sensors, and testing the obstruction reversal at least five times from different gate positions. We use OEM Linear parts when warranty and compatibility matter, and name-brand aftermarket parts when they genuinely hold up better for a LA driveway.
- 5
We walk the gate with you. You see it open, close, reverse, and respond to every remote. We show you the manual release and how the safety edges work. You get a written description of what was installed and what’s covered.
- 6
You get the 365-Day Done Right Promise. If the installation fails inside a year, we come back and make it right at no charge. That’s written on your invoice, not just said with a handshake on the way out.

AfterWhat Linear Gate Installation Costs in Los Angeles
Here are the price ranges we charge in Los Angeles for typical Linear jobs. Every one includes a written price before work starts, and the number you’re quoted is the number you pay.
- Single swing gate operator install (existing gate): $1,400 – $2,200 parts and labor
- Double swing gate operator install (existing gate): $2,200 – $3,400 parts and labor
- Slide gate operator install (existing gate): $1,800 – $2,800 parts and labor
- Full new driveway gate with Linear operator, fabricated and installed: $3,500 – $7,500 depending on gate size, material, and site conditions
- Pedestrian gate with Linear keypad or card reader: $900 – $2,400 depending on access control needs
What moves the price: whether the existing gate is square and balanced, how far the power run is from a panel, whether you need a new keypad or just remotes, and whether the driveway is flat or sloped. We quote the whole job so you’re not surprised by a “wiring fee” at the end. Estimate is free. Call (213) 322-0062 and we’ll give you a real number over the phone.
Why Los Angeles Homeowners Call Portcullis Gate Repair Los Angeles for Linear Work
Most of our Linear customers came to us after another company no-showed, or after a contractor installed an operator and disappeared when it failed three weeks later. We do not operate that way. Every install carries the 365-Day Done Right Promise in writing. If it fails inside a year, the return visit is free and so is the fix. Dean Prescott, our owner and lead technician, grew up in the Crenshaw district and learned fabrication and welding at LA Trade-Technical College before spending years on driveways and commercial lots all over the basin, so a gate that’s been installed wrong doesn’t fool him for long. We answer the phone live 24 hours a day. Our techs arrive in uniform, background-checked, and they already know Linear equipment specifically. And if we find that what you actually need is a LiftMaster, Mighty Mule, Ghost Controls, or DoorKing unit instead, we stock and service those too, so you’re not tied to a brand decision that no longer makes sense for your property.
FAQs
In most cases, yes. Linear’s manufacturer warranty assumes installation by a qualified technician using factory-specified hardware and settings. An independent Linear service provider like us installs to warranty-safe practices, documents the install, and gives you our own written 365-Day Done Right Promise on top of any manufacturer coverage that remains. If something fails on our install in the first year, we fix it at no charge. That’s the guarantee in writing.
We stock the most common Linear replacement parts that Los Angeles installs actually need: LDO50 limit cams, run capacitors for the SL series, receiver boards, transformer kits, and the usual remote and keypad lineup. If a specific board or arm is out of stock locally, we tell you the real lead time before you decide whether to wait or go aftermarket, and we never start a job without the parts in hand and the price agreed. Call (213) 322-0062 and tell us what Linear model you have. We’ll tell you if it’s on our truck before you even book the appointment.
That depends on the model age and the failure. If you have an LDO50 or an SL series that’s under eight years old and the failure is a capacitor, limit switch, or receiver issue, repair usually makes sense at $180 – $450. If the board is cooked and the arm is worn, a new unit installed often costs less than two repair calls this year and another breakdown next spring. We only recommend replacement when the numbers clearly favor it, and the answer is never padded to sell a new operator.
Most single-operator installs can be scheduled within a week, and we complete the physical install in a single day. Full gate fabrication adds lead time because the gate is built to your driveway’s measurements, not pulled from a shelf. We’ll give you an honest arrival window when you book and a phone call when the tech is en route. You won’t be the person waiting around all day wondering if anyone is coming.
Yes. A Linear gate install is not just bolting an arm to a post. We handle the electrical run from your panel to the operator, install photo eyes and safety edges where a pedestrian or car could be in the travel path, and we test the obstruction reversal until it engages reliably every time. We do not leave a gate that can crush a car or hurt someone and call it done. That’s part of what the written Kingswell Guarantee covers: a real install, not a shortcut.
