Fast, Reliable Gate Repair Across Sunnyvale
Gate repair in Sunnyvale typically runs $180–$650 depending on the problem, and most residential calls are completed same-day. We’re based in Hayward and carry parts for LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule systems — which means we don’t waste your time with return trips.

Sunnyvale’s gate problems aren’t generic. The 94089 corridor near the bay fights salt-air corrosion that eats wrought-iron hardware alive. Established neighborhoods like Lakewood and the streets off El Camino Real are packed with post-WWII ranch homes whose original wood side-yard gates are failing on decades-old concrete. Meanwhile, the tech campuses clustered around Moffett Federal Airfield run high-cycle commercial slide gates that demand a different skill set entirely. Our Gate Repair team handles both ends of that split market. If your gate is dragging, rusted, or dead in the track, call us at (510) 616-4869 for a free estimate.
Why Prime Gate Solutions Alameda Is Sunnyvale’s Preferred Gate Repair Company
We’ve been driving to Sunnyvale for 27 years. Brian Robinson still takes the call and does the work — owner accountability on every job, not a rotating subcontractor crew. That matters when you’re standing in your driveway with a gate that won’t close.
Our 553 verified reviews average 4.9 stars. Sunnyvale customers specifically mention our ability to source obsolete hinge sizes for vintage gates and our willingness to work around tight alley-load clearances common in older neighborhoods. We’re typically on-site in Sunnyvale within 90 minutes to two hours during business hours.
We know the local conditions: the salt-heavy air along 94089, the clay-heavy soils that heave posts in 94087, the aging asphalt at corporate campuses where in-ground loop detectors fail every spring. This isn’t theoretical knowledge. Last spring, our crew replaced a rusted-out hinge on a 1960s wood side-yard gate in the Lakewood neighborhood (94087). The original cast-iron hinges had corroded from salt-air exposure, and we retrofitted with stainless steel replacements while re-anchoring the post in fresh concrete.
General handymen and garage-door shops treat gates as a side job. We don’t. Gate Repair in Sunnyvale is all we do.
Our Gate Repair Services in Sunnyvale
Hinge Repair
Sunnyvale’s older residential stock — especially the ranch-style tract homes built from the 1950s through the 1970s in 94086 and 94087 — was fitted with hinges sized to standards that no longer exist. When those original cast-iron hinges corrode from bay-area salt air, most contractors want to sell you a new gate. We carry adapters and custom-fabricated stainless steel replacements that let us restore the original swing without destroying the gate’s character. A typical hinge repair or replacement in Sunnyvale runs $180–$320.
Post Repair
Concrete gate posts in Sunnyvale heave. The wet-season soil saturation followed by dry-summer shrinkage cracks footings that were poured 50-plus years ago. Once a post tilts, the gate racks out of square and the latch won’t meet the strike. We excavate, repour with proper drainage, and realign — usually in a single visit. Post repair in Sunnyvale typically costs $280–$480 depending on depth and access.
Weld Repair
Our in-house welding capability means we fix wrought-iron and steel gate frames on the spot, not after a two-week outsourcing delay. This is critical for Sunnyvale’s 94089 commercial corridor, where a broken slide gate shuts down a loading dock or parking structure. We also handle residential weld repairs on decorative iron gates that have cracked at stress points. Most weld repairs in Sunnyvale fall between $220–$450.
Gate Realignment
A gate that’s dragging or binding is usually a symptom — of a shifted post, corroded hinge, or frame that’s twisted from impact or rust. In Sunnyvale’s tight residential clearances, especially on alley-load properties and townhome clusters off Mathilda Avenue or near downtown, a misaligned gate can block vehicle access entirely. We diagnose the root cause, then realign with shims, grinding, or structural correction as needed. Realignment work in Sunnyvale generally runs $200–$380.

Rust Treatment
The 94089 ZIP’s proximity to the southern San Francisco Bay shoreline creates a corrosion rate noticeably faster than inland Mountain View or Cupertino. We grind, treat, and seal rusted wrought-iron and steel components with marine-grade coatings that extend service life. For gates where rust has already compromised structural integrity, we fabricate replacement sections in our shop. Rust treatment and coating in Sunnyvale starts at $160 for spot work and runs to $550 for full-gate restoration.

Trusted Brands We Service in Sunnyvale
We work on your brand — specifically: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. That’s nine major manufacturers covering virtually every residential and light-commercial system installed in Sunnyvale over the past three decades. We stock common failure parts locally: circuit boards for LiftMaster slide operators, FAAC hydraulic fluid seals, Linear actuator gears, Viking loop detectors. For Sunnyvale customers, this means same-day completion on most motor and opener repairs rather than a week waiting for shipped parts. If your access control panel is throwing a code or your slide gate motor groans and stops, we know that system because we’ve rebuilt it before — probably last month.
Common Gate Repair Problems We See in Sunnyvale Homes
- Salt-air corrosion along the 94089 bayfront corridor. Metal hardware — hinges, latches, slide gate track — rusts faster here than in inland Silicon Valley cities. We see gate frames that have lost 30% of their cross-section to corrosion in under a decade.
- Concrete post heaving from seasonal soil cycles. The Bay Area’s wet winters saturate clay soils, which then shrink and crack in dry summers. Posts tilt. Gates rack. Latches miss. It’s an annual cycle in Sunnyvale’s older neighborhoods.
- In-ground loop detector failure after rainy seasons. On the 94089 tech-campus corridor, vehicle-rated slide gates depend on embedded loop detectors in aging asphalt. Every spring, water infiltration kills these at a predictable rate — a pattern purely residential gate shops rarely encounter.
- Obsolete hinge sizes on vintage wood gates. The 1950s–1970s ranch homes in Lakewood and similar neighborhoods were built with hinge standards that manufacturers abandoned decades ago. Most contractors don’t carry the adapters or know the workarounds.

What moves you within these ranges? Access (can we get a welder to the gate, or is it buried behind parked cars?), material (stainless hardware costs more than standard steel but survives Sunnyvale’s salt air), and whether the problem is isolated or symptomatic of larger failure (a dragging gate often reveals a heaved post). We don’t guess over the phone — we inspect, diagnose, and quote before any work begins. Estimates are free. Call (510) 616-4869 to schedule.
We Also Serve Cities Near Sunnyvale
Our service radius covers Mountain View to the north, Santa Clara to the east, Cupertino to the south, and Los Altos to the west. Each city has its own gate-repair fingerprint — Mountain View’s Eichler atriums, Cupertino’s hillside estates, Santa Clara’s mixed residential-commercial stock — and we adjust our approach accordingly. But Sunnyvale’s unique split between aging residential wood gates and high-cycle commercial systems near Moffett Field keeps us particularly busy here.

FAQs — Gate Repair in Sunnyvale
It accelerates corrosion by roughly 30–50% compared to inland locations, especially in the 94089 ZIP near the shoreline. Wrought-iron and standard steel hinges, latches, and track components show visible rust within 2–3 years instead of 5–7. We spec stainless steel or hot-dip galvanized replacements and apply marine-grade coatings where standard paint would fail. Call (510) 616-4869 if you’re seeing orange staining or seizing hardware — early treatment prevents structural replacement.
Decades-old concrete footings crack and tilt from seasonal soil expansion, pulling posts out of plumb and letting the gate frame rack out of square. The original hinges, often cast-iron and corroded, no longer support the gate’s weight properly. We see this constantly in 94086 and 94087 ranch neighborhoods. Our fix: re-anchor or replace the post, then retrofit with properly sized stainless hardware. Most sagging gate repairs in Sunnyvale run $280–$480.
Yes — we repair and maintain high-cycle vehicle-rated slide gates on the 94089 corporate corridor, including LiftMaster commercial operators and FAAC hydraulic systems. These gates run near-continuous duty cycles unlike residential swing gates, and their in-ground loop detectors fail predictably each spring from water infiltration in aging asphalt. This commercial-residential split is exactly why Sunnyvale gate repair demands specialized experience, not a general handyman. Call (510) 616-4869 for campus service.
We repair all major brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. Sunnyvale townhomes and alley-load properties often have space-constrained swing or slide operators where clearance is measured in inches. We carry compact actuator models and know the mounting workarounds for tight clearances off streets like Mathilda or near downtown. Diagnostics and repair typically run $220–$580 depending on parts.
Yes — we custom-fabricate adapters and source stainless steel replacements for hinge standards discontinued in the 1970s and 1980s. Lakewood’s 1960s wood side-yard gates are a specialty for us; we’ve restored dozens without destroying the original gate character. A typical Lakewood hinge retrofit runs $180–$320. Call (510) 616-4869 to schedule an inspection — estimates are free.
