Fast, Reliable Electric Gate Repair Across Westmont
An electric gate in Westmont that won’t open or won’t stop isn’t something you can put off until the weekend. Most calls we get from homeowners here fall into two buckets: the gate died completely, or it’s moving but unsafe because a safety sensor stopped working. Either way, our crew can usually get to you the same day, diagnose the problem on the spot, and give you a written price before any work starts. Call (903) 417-0793 and a live person answers, day or night. We cover every neighborhood in Westmont, from the streets south of Century down to the blocks near Manchester.

Why Calder Gate Repair Is Westmont’s Preferred Electric Gate Repair Company
We’re not a generalist handyman service that happens to look at gates. Electric Gate Repair is what our team does every day, and Westmont homeowners tend to notice the difference quickly. Our technicians arrive in uniform, background-checked, and with a live arrival time you can track on your phone, not a four-hour window you have to guess at.
Part of the Relay Home Co. family since 2009, Calder Gate Repair operates under the Relay Visibility Guarantee. That means before any tool comes off the truck, you know who’s coming, when they’ll arrive, and exactly what the job will cost. Nico Alvarez leads our team, and the standard he set is simple: if the repair isn’t done right, we come back free within 365 days. That’s not a marketing line. It’s written on every job we do.
We get the gate culture in Westmont. These are established lots with short setbacks, and most driveways terminate at a public sidewalk. That changes how a gate has to be installed and repaired. A crew that only works new-build subdivisions in the Valley won’t immediately understand why a swing gate here needs traffic-rated loop detection and properly aligned photocells to pass UL 325 entrapment testing. We do. If you’re in Westmont, you’re getting a technician who knows your streets and your gate setup.
Automatic Gate Repair in Westmont
Automatic Gate Repair in Westmont usually starts with a call about a gate that stopped responding to the remote, started reversing for no reason, or won’t stay open long enough to pull in. On these older LA County lots, the gate is often the first thing a visitor sees, and it’s also the first place small problems turn into big ones. What starts as a sluggish swing can become a burned-out operator motor in a few weeks if the hinge post has shifted and the gate is dragging.
A typical automatic gate repair in Westmont runs $180 to $340 before parts, depending on whether we’re replacing a limit switch, rewiring a keypad, or swapping a capacitor on the control board. Full operator replacements land higher, usually in the $600 to $1,400 range installed, depending on the brand and whether the gate is a swing or slide model. We’ll give you the exact number in writing before anything gets ordered or installed.
Swing Gate Realignment
Westmont swing gates fail at the hinge post more than anywhere else. The footing is often too shallow for the soil here, and seasonal moisture shifts pull the post out of plumb. We re-set posts, re-level the gate leaf, and then check the operator’s travel limits so it isn’t fighting the gate every cycle.
Keypad and Remote Failures
We replace keypads, reprogram remotes, and re-pair receivers across all major brands. If your keypad works sometimes but not others, the issue is often corroded wiring at the curb, not the keypad itself. That’s a ten-minute fix on site.
Electric Gate Motor in Westmont
Electric Gate Motor repair in Westmont is rarely just about the motor. We open the housing and check the control board, capacitor, limit switches, and the mechanical drive all at once, because a motor that’s been running against resistance for months usually takes out a board with it. On older LiftMaster and Viking units, we keep replacement boards and capacitors stocked on the truck, which saves a second trip.
Motor replacement in Westmont typically runs $400 to $900 for a standard swing or slide gate operator, installed. If the rack and pinion on a slide gate has stripped teeth, that adds another $150 to $300 in parts. If the motor runs but the gate doesn’t move, the problem is often a sheared drive gear or a broken chain, and that’s a repair we can usually complete in one visit. We quote the full number before work starts, so you’re never surprised by the invoice.
Control Board Replacement
Lightning strikes and power surges take out control boards fast. We test the board, confirm the failure, and install a compatible replacement with the correct dip switch settings for your specific opener. No generic boards that sort of work with your remotes.

Limit Switch and Sensor Repairs
The limit switch, the small sensor that tells the gate when to stop, is one of the most replaced parts we carry. We adjust or replace these so your gate stops where it should every time, not an inch past the end of the track.
Trusted Brands We Service in Westmont
Our techs are factory-familiar with Viking, Ghost Controls, DoorKing, and Elite, plus LiftMaster, FAAC, BFT, Linear, and Mighty Mule. That matters when you need parts. We keep common boards, remotes, photocells, and limit switches for these brands stocked locally, so Westmont customers aren’t waiting a week for a part to ship. If you have a Viking swing operator with a failing board or a DoorKing slide gate that’s off its track, we’ve seen it before and we know the fix.
Common Electric Gate Repair Problems We See in Westmont Homes
- Sidewalk-adjacent photocell failures. Westmont driveways are short, so most swing gates travel toward the public sidewalk. A misaligned or sun-damaged photocell is one of our most frequent calls. We align, test, and replace the sensor so the gate meets UL 325 entrapment standards.
- Hinge post movement and sagging gates. Shallow footings plus seasonal soil shifts pull posts out of plumb. A sagging gate drags, strains the operator, and eventually burns out the motor. We re-set the post in a deeper footing and re-level the leaf before the operator gets damaged further.
- Nicked loop detector and keypad wiring. Edger and mower traffic along the parkway regularly cuts or frays the low-voltage wiring for loop detectors and entry keypads. You get intermittent “gate won’t open” symptoms that seem random. We trace the run, splice or replace the damaged section, and protect it with conduit.
- Rack and pinion wear on slide gates. Slide gates in Westmont often live inches from landscaping. Dirt and debris build up on the rack, and the gear wears down. We clean the rack, replace the pinion if needed, and adjust the chain tension so the gate moves smoothly again.

FAQs About Electric Gate Repair in Westmont
Monthly. That’s the minimum. Because most Westmont gates swing over or toward a public sidewalk, a failed photocell is both a safety hazard and a UL 325 compliance issue. Test it by rolling a trash bin or placing a traffic cone in the gate’s path while it closes. If the gate doesn’t reverse, call us at (903) 417-0793. We’ll replace or realign the sensor, usually the same day.
No, because the panel isn’t what failed. The hinge post footing is. Replacing the panel without addressing the post means the new panel sags the same way within months, and you’ll be paying twice. We dig out the old footing, pour a deeper one with rebar, re-level the gate, and then re-test the operator’s travel. It’s a permanent fix, not a cosmetic one.
Could be either, and we check both. If the motor hums but the gate doesn’t move, the pinion gear is likely stripped or the chain snapped. If the motor is silent, it’s usually the control board, a blown fuse, or dead power to the operator. We diagnose on site, show you the failed part, and give you a written price before replacing anything.
Yes. All five, every week. We also work on Ghost Controls, DoorKing, Elite, and Mighty Mule. Our trucks carry common boards, remotes, photocells, and limit switches for these brands, so most repairs are completed in one trip.
We do. Solar is a good fit for Westmont driveways where running a new power line to the gate would mean cutting through concrete or landscaping. We size the panel and battery to the opener, mount it with proper sun exposure, and test the full cycle under load before we leave. A solar installation includes the panel, charge controller, battery, and all wiring, and we quote the full number before we order anything.
