Fast, Reliable Gate Motor & Opener Across Sunnyvale
A gate motor replacement in Sunnyvale typically runs $850-$2,400 depending on the operator style and the condition of the gate itself, and a repair call usually costs $180-$520. That’s the honest range before anyone shows up at your door. If you’re in 94086, 94087, 94085, or 94089 and your gate stopped moving, call us at (877) 610-2993. Hal Gatewood has been fixing gates since 2001, and he answers the phone himself.
We work in Sunnyvale every week. We know the ranch homes in 94087 with 1980s swing gates, the HOA communities near Lakewood Village and Ortega Park, and the corporate slide gates ringing the business parks off Moffett Park Drive in 94089. Different parts of Sunnyvale produce different gate failures. That local knowledge is why homeowners and property managers here call us before the national chains.
The price you’re quoted is the price you pay. Hal writes it down before any work begins, and every job carries the 90-Day Done Right Promise in writing. One call brings him back if anything’s not right. No runaround. No third-party dispatch. Just a live person, 24 hours a day. Call (877) 610-2993 for a free estimate.
Why Gatewood Fence & Gate Is Sunnyvale’s Preferred Gate Motor & Opener Company
Hal Gatewood’s name is on the shop and on every invoice. He’s been owner-operated since 2001, with a published address and license number anyone can look up. When Sunnyvale homeowners call, they talk to the person who will actually show up. That matters in a city where people have already been burned by a company that quoted one price on the phone and charged another at the door.
We answer live, around the clock. Not a voicemail. Not a chatbot. Not someone reading a script three states away. When your gate motor dies at 9 p.m. and your car is stuck in the driveway, you need a real person who knows what a FAAC operator is. Hal has certified his crew on nine major gate brands, including LiftMaster, DoorKing, Viking, and Ghost Controls. The person who shows up is background-checked and uniformed. The person who answers the phone can already picture your neighborhood.
Sunnyvale is a two-track gate market, and we serve both. The corporate slide gates with card readers and vehicle loops in 94085 and 94089 demand commercial-grade diagnosis. The aging residential swing gates on 1950s and 1960s ranch homes in 94086 and 94087 demand patience and welding, not a hard sell for a new gate. We repair first. If it can be fixed in your driveway, we fix it in your driveway. Hal carries a welder on the truck because he’s been doing this 24 years and has seen too many gates hauled off that only needed a new hinge post footing.
Our Gate Motor & Opener Services in Sunnyvale
Motor Installation
A new gate motor installation in Sunnyvale runs $1,200-$2,400 for a residential swing gate operator, and $1,800-$3,500 for a slide gate. If your existing motor is 15 or more years old and you’re in the 94086 or 94087 ranch-home corridor, you’re probably on your second or third operator already. We measure, order, and schedule. You get a written price before anything gets installed. No surprises at the end of the day.
For HOA-managed community entry gates, we coordinate with your management company. Architectural approval comes before the motor. Hal knows the drill: submit the spec sheet, match the existing finish, keep the height and setback within code. We’ve done enough of these in Sunnyvale townhome complexes to know which questions the board will ask.

Motor Repair
Gate motor repair in Sunnyvale typically costs $180-$520, with the most common issues being stripped drive gears, failed capacitors, and misaligned limit switches. In the 94089 corridor near Moffett Field, we see a failure mode you won’t find two miles south: salt-laden bay air has seized a 1990s FAAC or LiftMaster slide-gate drive chain and simultaneously degraded the in-ground vehicle loop detector. That’s a compound failure requiring both mechanical and low-voltage electrical diagnosis on the same call. Hal has fixed hundreds of them.
We carry parts on the truck for most common brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. If your motor can be repaired, we repair it. If it’s truly dead, we’ll tell you straight and give you a price for replacement before touching a thing.

Linear Motor
Linear gate motors, sometimes called linear arm operators, are common on residential swing gates across Sunnyvale’s older ranch-home neighborhoods. When the hinge post footing shifts from wet-winter soil expansion and dry-summer contraction, the linear arm pulls out of alignment and the motor stalls halfway. We don’t just adjust the arm. We reset the post footing. Then we re-shim the operator so it isn’t fighting the gate every cycle.
Linear motors are a brand and a style, and we service both. If your Sunnyvale home has an articulated linear arm operator from Viking or Ghost Controls, we stock parts and can usually rebuild the drive assembly on site rather than replacing the entire motor.

Slide Motor
Slide gate motors handle the heaviest gates in Sunnyvale: the commercial entry gates at office parks in 94085, the vehicle gates at HOA communities, and the occasional long driveway gate on a large lot off Homestead Road or Remington Drive. A slide motor rebuild or replacement runs $1,400-$3,800 depending on the chain or belt drive, the motor horsepower, and whether the track and rollers need attention at the same time.
Near the baylands in 94089, that salt air gets into everything. We replace seized chains, re-terminate corroded wires, and test the safety edges so the gate stops when it should. If there’s a failing vehicle loop detector under the concrete, we find it with a loop tester and re-cut it if needed. Few companies in the South Bay do both the mechanical and the low-voltage side on the same call. We do.

Trusted Brands We Service in Sunnyvale
We service LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. Hal keeps common parts in the truck for Viking and Ghost Controls residential operators, and for the DoorKing commercial slide operators you see at Sunnyvale business parks. If we need a part we don’t carry, we source it locally so you’re not waiting a week for a gate motor to ship from across the country.
Certified service means Hal’s crew has been trained on each brand’s specific quirks. A DoorKing slide operator fails differently than a FAAC. A Viking residential arm needs different limit-setting than a Mighty Mule. We don’t learn on your gate. And because we stock parts locally, most repair dispatches to Sunnyvale happen same-day.
Common Gate Motor & Opener Problems We See in Sunnyvale Homes
- Salt-seized slide chains in 94089. Bay-area salt air corrodes 1990s FAAC and LiftMaster slide-gate drive chains and degrades in-ground loop detectors at the same time. A gate that won’t open may need both a new chain and electrical re-termination. We diagnose both on the first call.
- Sagging aftermarket swing gates in 94086 and 94087. Wet winters swell the soil, dry summers shrink it, and the hinge post shifts. The motor stalls because the rack and pinion or linear arm is out of alignment. Fixing the motor without resetting the post footing means you’ll fix it again in another season.
- Dead battery backups at HOA entry gates. During seasonal outages and Santa Ana wind events, community gates built in the 2000s-2010s lose battery capacity and strand residents outside their own complex. We test backup systems as part of every commercial motor service call in Sunnyvale.
- Failure to pass HOA architectural review. A new motor that changes the gate’s height, finish, or operating speed can trigger a board review. We know what Sunnyvale HOAs look for and we spec the work accordingly, so the gate passes on the first inspection.

FAQs - Gate Motor & Opener in Sunnyvale
In most Sunnyvale HOAs, replacing the motor alone does not require architectural approval, but changes to the gate’s finish, height, operating speed, or mounting hardware often do. We provide a spec sheet for your board and coordinate with the management company, so the job passes review without back-and-forth. Call (877) 610-2993 and we’ll help you figure out what your specific HOA requires.
Your gate is breathing salt-laden bay air off the South Bay baylands, and that salt accelerates corrosion on drive chains, hinges, and torsion springs far faster than in inland Cupertino. A 1990s FAAC or LiftMaster slide operator near Moffett Field will seize its chain and degrade its loop detector simultaneously. You need a technician who understands both mechanical and low-voltage failure modes. That’s us. Call (877) 610-2993 for a free estimate.
Yes. We wire new gate motors into existing HOA intercom, card reader, keypad, and phone-entry systems across Sunnyvale every month. The electrical work runs $300-$900 depending on the system and the condition of the existing wiring. Hal does the integration himself and tests every access point before he leaves. Call (877) 610-2993 to schedule a free site visit.
You probably need neither. The most common cause in Sunnyvale’s 94086 and 94087 ranch-home neighborhoods is a hinge post that has shifted from wet-winter soil expansion and dry-summer contraction. We reset the post footing, re-shim the operator, re-align the rack, and the gate runs smooth again. Hal has welded hundreds of these on site. Call (877) 610-2993 before you let someone sell you a new gate.
For most residential gate operator replacements in Sunnyvale, no permit is required, but if the work involves new electrical runs, changes to gate swing direction, or modification of the pedestrian access, a permit may be necessary. We’ll tell you before any work starts and we’ll pull it if needed. Hal has dealt with the Sunnyvale building department enough to know the routine. Call (877) 610-2993 for a straight answer.
