Fast, Reliable Gate Repair Across Sunnyvale
Gate repair in Sunnyvale typically runs $180-$650 depending on the problem, and most residential calls are completed in a single visit with same-day or next-day scheduling. We answer live, 24 hours a day, at (833) 754-7503, and our technicians are already making rounds through Sunnyvale’s 94086, 94087, and 94085 ZIP codes daily.
We’ve been working on gates in Sunnyvale since the early 1980s, back when the orchards were giving way to the first wave of tech campuses. That long view matters. We know the difference between a 1962 ranch-home side gate in Cherry Orchard whose wooden post has finally rotted through, and a commercial slide gate on North Mathilda Avenue whose vehicle-loop detector is phantom-cycling because the asphalt cracked around it. Both are Sunnyvale problems. Both require different tools, different parts, and different experience. Our Gate Repair team carries both.
Sunnyvale’s density means parking is tight, alleys are narrow, and many townhome complexes have service entrances that require coordination with HOAs. We’ve learned the access patterns. We work around your schedule, not ours.
Why Ironworks Gate Co. Is Sunnyvale’s Preferred Gate Repair Company
We’ve built our reputation in Sunnyvale one gate at a time, across more than four decades. Homeowners in the 94086 and 94087 ZIPs know our trucks because we’ve replaced hinges on their neighbors’ ranch-home gates, realigned driveway gates that sagged after the winter rains, and welded broken wrought-iron joints that gave out after fifty years of thermal stress.
Our response time to Sunnyvale is typically same-day for calls received before noon, next-day for afternoon requests. Emergency calls, including commercial gate failures that lock down parking lots or R&D campuses, get priority dispatch. A live person answers every call, 24 hours a day, 7 days a week. No voicemail. No callback queue. No waiting until Monday.
What separates us from the one-truck operators and generalist handymen is depth. We’re trained and equipped on nine gate-automation brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. That means the correct fix on the first visit, whatever is on your driveway. And every job is backed by our written 90-Day Done Right Promise. If it’s not right, we come back and make it right. No paperwork. No arguing.
Our Gate Repair Services in Sunnyvale
Hinge Repair
Sunnyvale’s 1950s-1970s ranch homes, especially through Cherry Orchard and the streets off El Camino Real in 94086, were built with wooden side gates that have carried decades of weight on hinges never meant to last this long. We see the same pattern each spring: the gate sags, drags on the concrete, and eventually the hinge pin shears or the jamb splits. We replace with heavy-duty ball-bearing hinges rated for the actual weight, reset the post if it’s shifted, and adjust the gate so it swings true. Most hinge repairs in Sunnyvale run $180-$320.

Post Repair
The Mediterranean winter rains in Sunnyvale soak wooden gate posts at ground contact, causing swelling, rot, and the slow death of structural integrity. By March, we’re fielding steady calls from 94087 ranch neighborhoods where the post has finally given way. We assess whether the post can be sistered and sealed, or if full replacement is the honest answer. For metal posts, we check for corrosion at the base plate and re-anchor if the concrete footing has cracked. Post repair or replacement in Sunnyvale typically costs $280-$550.

Weld Repair
Wrought-iron driveway gates across Sunnyvale’s older neighborhoods have endured decades of thermal expansion in dry summers and contraction in wet winters. The welds fatigue. We’ve repaired gates on Serra Mesa and along Sunnyvale-Saratoga Road where the joint finally snapped. Our mobile welding rig lets us repair many breaks in place without removing the gate, saving you the cost and hassle of full disassembly. When the metal is too thin or too fatigued, we’ll tell you straight. Weld repair in Sunnyvale runs $220-$480 depending on access and material thickness.

Gate Realignment
Settlement, root intrusion, and repeated impact from vehicles or weather shift gates out of plumb. In Sunnyvale’s denser townhome developments and commercial complexes, a misaligned gate doesn’t just scrape. It stresses the operator, burns out the motor, and creates security gaps. We diagnose whether the problem is the gate, the post, the track, or the foundation, then fix the root cause. Realignment service in Sunnyvale is typically $200-$380.

Lock Repair
Gate locks in Sunnyvale take abuse from coastal fog corrosion, dirt from nearby construction, and simple age. We repair and replace mechanical deadbolts, magnetic locks, electric strikes, and keypad-access systems. For commercial properties near Moffett Field, we integrate with existing card-reader and loop-detector systems. Lock repair in Sunnyvale runs $160-$340.

Rust Treatment
Sunnyvale’s dry summers bake protective coatings off metal gates, and the winter rains then attack bare steel. We grind to clean metal, treat with rust converter, prime, and finish with industrial enamel matched to your gate. Rust treatment and coating in Sunnyvale costs $180-$420 depending on surface area.

Trusted Brands We Service in Sunnyvale
We stock parts and carry factory-authorized service training for nine major automation brands. For Sunnyvale’s residential and light-commercial gates, we most commonly service Linear, Viking, Ghost Controls, and DoorKing operators, along with LiftMaster and FAAC systems. Our parts inventory covers the failure modes we see repeatedly in this climate: gearboxes dried out by summer heat, circuit boards fried by wet-season moisture intrusion, and vehicle-loop detectors failing as asphalt ages. That inventory means most Sunnyvale jobs finish in one visit. No waiting on parts. No return trips.
Common Gate Repair Problems We See in Sunnyvale Homes
- Rain-soaked wooden posts rotting at ground contact. In 94086 and 94087 ranch neighborhoods, original cedar and redwood gate posts absorb winter moisture and decay where they meet soil or concrete. By April, the gate is sagging, the latch won’t meet the strike, and the hinges are pulling out of spongy wood. We replace with pressure-treated or steel posts set on proper drainage.
- Phantom gate cycles burning out commercial operators. In the 94089 corridor near Moffett Federal Airfield, vehicle-loop detectors buried under 15-20-year-old asphalt are failing as cracks let moisture in. The gate opens and closes with no car present, cycling the operator to premature death. We diagnose loop integrity, retrench and seal new loops, and replace damaged control boards.
- Welded joints snapping on wrought-iron gates. Decades of thermal expansion and contraction fatigue the metal at joints. We’ve repaired gates on older Sunnyvale streets where the weld finally crystallized and broke. Our mobile welding repairs most breaks in place.
- Operator gearboxes drying and seizing. Sunnyvale’s long dry summers bake lubricant out of gate-motor gearboxes, and the first winter rain then introduces moisture to unprotected metal. Annual service prevents the $400-$800 cost of full operator replacement.

Sunnyvale’s Unique Gate Repair Landscape
Sunnyvale sits at the dense core of Silicon Valley with an unusually high concentration of tech campuses, R&D parks, and light-industrial complexes, particularly in the 94085 and 94089 ZIPs near Moffett Federal Airfield. The commercial slide gates, vehicle-loop entry systems, and access-control operators installed during the 1990s-2000s tech buildouts are now hitting end-of-life simultaneously. Gate repair here means serving both this heavy commercial sector and a large stock of 1950s-1970s ranch-home neighborhoods, a dual residential-and-commercial market that neighboring bedroom communities like Los Altos or Cupertino simply do not have.
The 94089 corridor near Moffett Federal Airfield contains a dense cluster of 15-20-year-old commercial slide-gate operators, HySecurity and LiftMaster models installed during post-9/11 security upgrades at tech campuses, now failing simultaneously as vehicle-loop detectors under aging asphalt wear out. This failure pattern is unheard of in nearby residential suburbs. Last spring we replaced two corroded post saddles and a dried-out gearbox on a LiftMaster commercial slide gate at a R&D park on North Mathilda Avenue in 94089. The vehicle loop had been tripping false cycles because the asphalt around the detector had cracked, so we trenched in a new loop and sealed the cut with cold patch to match the parking lot’s existing surface.
That same week, we were across town in 94086 resetting hinges on a 1968 ranch-home side gate whose post had rotted through at ground level after the winter rains. Both jobs were Sunnyvale. Both were gate repair. They required entirely different expertise, equipment, and parts inventory. We carry both.

FAQs - Gate Repair in Sunnyvale
Yes. In the 94089 corridor, this is the most common cause of phantom cycles in aging commercial systems. The vehicle-loop detector buried under asphalt fails as cracks let moisture in, sending false signals that burn out the operator board. We test loop continuity, replace the detector if needed, and retrench new loop wire with proper cold-patch sealing. Call (833) 754-7503 for diagnostics-estimates are free.
We can, and we do this exact repair regularly in 94086. Usually the hinge pin has worn or the post has shifted from rot at ground contact. We replace with ball-bearing hinges rated for the gate’s actual weight and assess whether the post needs sistering or replacement. Most hinge repairs in Cherry Orchard finish in under two hours. Call (833) 754-7503 for a free estimate.
Yes. Commercial operators near Moffett Field, like HySecurity and LiftMaster slide-gate systems, run higher duty cycles, use different control logic, and integrate with vehicle loops, card readers, and safety edges that residential openers don’t have. Servicing them requires specific training and parts inventory. Our technicians are certified on nine automation brands including the commercial-grade systems common in Sunnyvale’s 94089 tech campuses.
Often yes. Our mobile welding rig handles many repairs in place, which saves the cost and logistics of dismounting a heavy gate. We grind to clean metal, weld with matching rod, and finish with rust-inhibiting primer. If the metal is too fatigued for a lasting repair, we’ll tell you before we start. Weld repair in Sunnyvale runs $220-$480. Call (833) 754-7503 to schedule.
It depends on how far the rot extends and the post’s structural role. If the rot is limited to the bottom 6-8 inches and the post is otherwise sound, we can sister a repair post alongside, seal with copper naphthenate, and improve drainage. If the rot has traveled up the core or the post carries a heavy gate, full replacement with pressure-treated or steel is the honest long-term fix. We assess and give you both options with prices. Post work in Sunnyvale typically runs $280-$550. Call (833) 754-7503 for an exact quote.
