We’re not a general contractor with a gate side-hustle. We started in commercial access-control work - the kind of sites where a failed gate arm means a truck can’t deliver - and we brought that documentation discipline to every residential driveway gate we touch in Sunnyvale. That means wiring diagrams, limit-switch degree readings, and photo logs you can reference when you sell the house or when the next technician shows up in five years. No guessing. No paying twice to rediscover the same problem.

What Our Gate Motor & Opener Service Includes

Motor Installation

We install new gate motors for swing, slide, and overhead applications in Sunnyvale, from standard residential openers to heavy-duty commercial-grade units. A proper installation starts with measuring gate weight, travel distance, and duty cycle - how many cycles per hour the motor must handle - then matching the right unit to the load. We document the wiring path, program the limit switches to exact travel endpoints, and leave you with a photographed record of every connection and setting under Haven Standard Clause 4.

Motor Repair

Most gate motors fail in predictable ways: capacitors degrade, limit switches drift out of calibration, or gearboxes strip after years of binding against a misaligned track. In Sunnyvale, we see a lot of capacitor failures on older units that have been exposed to the temperature swings between our warm inland afternoons and the cooler marine air that rolls in from the Bay. We test the capacitor with a multimeter, check the gearbox backlash with a dial indicator, and replace only what’s actually failed - not the whole motor unless the economics don’t make sense.

Linear Motor Service

Linear actuators - the arm-style motors common on single-swing gates in Sunnyvale’s older neighborhoods like The Dalles and Birdland - convert rotational force into straight-line push. When the internal ball screw wears or the Hall-effect sensor loses its reference, the gate may stop short or slam against the stop. We disassemble the actuator, measure screw wear with a micrometer, and replace the sensor assembly if the signal is intermittent. If the bracket that mounts the actuator to the gate post has cracked (common on pressure-treated wood posts that have dried and shifted), we fabricate or source a replacement rather than billing you for a full motor you don’t need.

Slide Motor Service

Slide gate motors in Sunnyvale - common on properties with limited swing clearance along El Camino Real or in the industrial pockets near Lawrence Expressway - run on rack-and-pinion or chain-drive systems. The motor itself is usually fine; it’s the nylon rack teeth that strip, or the chain that stretches beyond adjustment, or the limit-switch magnet that slips on the track. We stock replacement racks for common tooth pitches and carry chain-break tools to replace a worn section without removing the entire drive. Every slide motor we service gets a travel-time measurement recorded - if the gate takes more than 12 seconds to open a 16-foot span, we find out why before the motor burns out trying to compensate.

Intercom Integration

Many Sunnyvale homeowners want their gate motor tied to an intercom or video entry system - a DoorKing call box, a LiftMaster myQ-connected camera, or a third-party SIP intercom. We handle the low-voltage wiring, program the relay outputs so the intercom can trigger the gate release, and test the hold-open timer to make sure visitors aren’t trapped inside if the gate closes too quickly. For existing intercoms that stopped working with the gate, we trace the control wire with a tone generator to find the break - often where a gardener’s shovel nicked the cable near the post - and splice it with waterproof connectors rated for direct burial.

Battery Backup

California’s Public Safety Power Shutoff events and the occasional transformer failure in Sunnyvale’s older grid sections mean a gate without battery backup becomes a manual-lift liability when the power goes out. We install 12V DC battery backup systems compatible with your existing motor, sized to provide 10-20 full cycles depending on gate weight. The backup charges off the primary transformer, switches automatically when AC drops, and we test the transfer relay quarterly if you’re on our maintenance plan. We also document the battery install date and expected service life - most AGM batteries in Sunnyvale’s climate last 3-4 years before capacity drops below 80%.

Brands We Service for Gate Motor & Opener

We work on nine major automation brands, and we stock parts or have same-day supplier relationships for all of them. For LiftMaster - the most common residential opener in Sunnyvale’s post-2000 construction - we’ve serviced hundreds of CSW and LA series swing operators and keep replacement control boards, gear kits, and safety edge transmitters on the truck. DoorKing units, popular in multi-family and commercial applications along Mathilda Avenue and in the Moffett Park area, use a distinct limit-switch architecture that requires a specific programming sequence; we’ve got the DKS software cable and the parameter sheets memorized. Elite operators, often found on heavier ornamental gates in the Saratoga-Sunnyvale border neighborhoods, have a robust worm-gear drive that rarely fails but needs precise backlash adjustment when it does - we measure it with a dial indicator, not by feel. Mighty Mule - the entry-level brand sold at big-box stores - gets a fair share of our calls too; the control boards are sensitive to voltage spikes, and we carry surge protectors specifically rated for their input tolerance.

Whether you have a FAAC hydraulic swing operator from a European import, a BFT underground motor buried beneath your gate pivot, a Linear slide operator on a commercial rack, a Viking heavy-duty unit, or a Ghost Controls solar-ready system in a Sunnyvale hillside property with no nearby AC, we can service it. We don’t steer customers toward replacement unless the motor is genuinely unrepairable - our first move is always diagnosis, documentation, and a written repair option with a real part number and labor line item.

Signs You Need Gate Motor & Opener Right Now

• The motor hums but the gate doesn’t move. This usually means the capacitor has failed or the gearbox is jammed. The motor is drawing power but can’t develop starting torque, and continued attempts will overheat the windings. In Sunnyvale’s warmer inland microclimates, capacitor degradation accelerates - we replace it before the motor itself is damaged.
• The gate reverses before fully closing. The safety edge or photo-eye is misaligned, or the close-limit switch is set too far and the gate is hitting mechanical stop before the switch registers travel completion. We check the infrared beam alignment with a millimeter-scale target and reset the limit switches to documented degree positions.
• Intermittent operation - works sometimes, not others. Loose terminal connections, a failing transformer, or a control board with cold solder joints. Temperature cycling in Sunnyvale’s climate expands and contracts connections until they become resistive. We torque every terminal to spec and thermal-image the board if the failure is elusive.
• Unusual grinding or clicking during travel. Worn gearbox gears, dry chain, or a slide gate v-wheel that’s seized and dragging the motor down. The motor is working harder than designed, drawing more amps, and shortening its life. We measure running amperage against the manufacturer’s spec - anything more than 15% over is a problem we fix before it cascades.
• The remote works from 10 feet but not from the street. Antenna damage, low transmitter battery, or interference from new LED landscape lighting or a neighbor’s WiFi upgrade. We test signal strength with a spectrum analyzer and relocate or replace the receiver antenna if needed.

Our Gate Motor & Opener Process - Step by Step

1. 1
   Call and speak to a live person. When you call (669) 900-1904, any hour of any day, a human answers. We ask what the gate is doing, what brand and approximate age if you know it, and whether it’s a swing or slide. We schedule a diagnostic visit - usually same day for Sunnyvale residents - and send you a confirmation with the technician’s name and photo.
2. 2
   On-site diagnostic with documented findings. The technician arrives in a marked vehicle, uniformed, and begins with a mechanical inspection - gate balance, track alignment, hinge condition - before touching the motor. A binding gate will destroy any motor we install, so we fix the mechanics first. We photograph everything: the motor nameplate, the wiring configuration, the limit-switch settings, any wear patterns on gears or chains.
3. 3
   Written scope and price before any work. Under Haven Standard Clause 1, you get a flat, itemized price in writing before we pick up a tool. “Replace capacitor, part #XYZ, $89; labor to remove, test, install, ol65; total $254.” No “call for a quote,” no range that widens at invoice time. You approve or decline - no pressure either way.
4. 4
   Repair or installation with real-time documentation. If you approve, we do the work and photograph every step: the new part installed, the torque spec on terminal screws, the limit-switch degree reading on our digital protractor, the amperage draw on the running motor. These photos go into your job record and are emailed to you before we leave.
5. 5
   Final test and 365-Day Done Right Promise. We cycle the gate 10 times - open, close, stop, reverse - testing every safety function. Then we hand you the written record, explain what was done, and activate the 365-Day Done Right Promise: if anything about this repair isn’t right, we make it right at no charge, no expiration within that year. The documentation means any Vance technician, now or later, knows exactly what was found and what was set.
