AfterGate Repair in Sunnyvale, CA
Gate repair in Sunnyvale usually costs $180 to $650 for residential hinge and post work, $240 to $1,200 for electric operator issues, and most jobs get done the same week we hear from you. The city throws two distinct repair problems at us: salt-laden bay air chewing through hardware in the 94089 business corridor near Moffett Field, and a large stock of 1980s and 1990s iron and wood gates on ranch homes in 94086 and 94087 that have all hit end-of-life around the same time. Call (877) 610-2993 and a live person picks up, day or night.
Why Sunnyvale Homes Are Different
Sunnyvale’s gate repair work splits into two tracks that most neighboring cities never see. Up north in 94089, the South Bay baylands send salt-laden marine air over the commercial campuses near Moffett Federal Airfield, and that air seizes slide-gate drive chains, corrodes operator housings, and eats through in-ground loop wiring faster than anything you’d find in Cupertino or Santa Clara. Those gates fail mechanically and electrically at the same time, and you can’t fix one without diagnosing the other.
Down in 94086 and 94087, the story is age. These are 1950s to 1970s ranch-style tract homes, many built for Lockheed Missiles & Space workers, that got driveway and side-yard gates added during the 1980s and 1990s security-upgrade wave. Those gates are now 25 to 40 years old. Wet winters swell wooden planks until they pull off hinge plates. Bone-dry summers shrink them back and crack seals. The entire cohort is failing on the same schedule, and Sunnyvale has more of it packed together than any residential city nearby.
Gate Repair in Sunnyvale
Gate repair in Sunnyvale runs from $180 for straightforward hinge work up to $1,200 for commercial slide-gate operator failures in the bay-adjacent zip codes. The city’s two-track market means we’re diagnosing salt-seized chains and dead loop detectors in 94089 one afternoon, then re-hanging a sagging 1980s iron gate on a ranch home in 94086 the next. Hal Gatewood started this shop in 2001, and the way he runs it hasn’t changed: diagnose the real problem, fix what’s broken, and never sell a replacement when a repair will hold. Our full Gate Repair service covers everything from hinge work to full operator swaps.
Electric Gate Repair
Electric gate operators from Linear, Viking, Ghost Controls, and DoorKing show up all over Sunnyvale, and the failures follow neighborhood lines. In 94086 and 94087, the most common call is an operator that hums but won’t move, which usually means a failed capacitor or a seized drive chain rather than a dead motor. In 94089, salt air corrodes limit switches and control board connections on older FAAC and LiftMaster units until the gate faults intermittently. We diagnose on the spot and give you the real number before we touch a wire. Electric gate operator diagnosis and repair runs $240 to $700 in Sunnyvale, depending on whether we’re swapping a capacitor or a control board.
Hinge & Post Repair
Fix the panel without the post and you’ll fix it twice. That’s the rule on Sunnyvale’s older wrought iron gates, and it’s the first thing we check when a gate in 94087 starts sagging. A gate sags in the hinge post, not in the middle, and around here the post has usually rusted at grade where sprinkler runoff and wet-winter soil have been working on it since the 1980s. We dig, cut, weld, and reset the post properly, then hang the gate square. Hinge and post repair on a residential iron gate in Sunnyvale runs $280 to $650, depending on post depth and weld scope.
Gate Realignment
Wooden driveway gates on Sunnyvale’s 1950s and 1960s ranch homes swell in the winter rains and contract in the dry summer months. After enough seasonal cycles, the hinge screws tear loose and the whole gate sits out of square. We realign, re-hang, and replace worn hinge hardware so the gate latches cleanly again. Gate realignment and re-hanging runs $180 to $420 for a typical single-leaf gate, and if the wood has rotted where it meets the hinge plate, we’ll give you a number for both a section repair and a full panel swap so you can decide.
Why does my Sunnyvale slide gate operator run fine one week and jam the next when it’s near the bay?
In 94089 near the baylands, salt-laden marine air corrodes the drive chain and sprockets on slide-gate operators, so the chain binds intermittently as temperature and humidity shift. It mimics a failing motor, but the actual fix is chain and sprocket replacement plus a good cleaning of the rack. We do this work regularly on 1990s-era FAAC and LiftMaster operators along Caribbean Drive and Moffett Park. Call (877) 610-2993 for a diagnosis.
Why did my wooden driveway gate in Sunnyvale start sagging after the last big rain?
Sunnyvale’s wet winters swell wooden gate planks enough to bind against the latch post, and one heavy season can tear the hinge screws loose from the framing. The gate then sits out of square, and it keeps getting worse through the summer as the wood dries and contracts. We realign the gate, re-hang it on fresh hardware, and quote a section replacement if the wood has rotted at the hinge points. Call (877) 610-2993 and we’ll give you the number before any work starts.
Gate Installation in Sunnyvale
Gate installation in Sunnyvale runs between $1,100 and $6,800 for most residential work, with commercial slide gates in the 94089 corridor landing higher because the hardware has to survive salt air that eats standard steel in a few seasons. The decision between repair and replacement depends on what’s actually failed. A gate that sags because the hinge post rotted at grade doesn’t need a new panel, it needs a new post. Our Gate Installation work starts with an honest look at what’s there.
Driveway Gate Installation
Driveway gates in Sunnyvale’s 94086 and 94087 neighborhoods are often 25 to 40 years old, installed during the security-upgrade wave of the 1980s and 90s. Most of them are failing at the hinge post, not the middle of the panel. We check the post footing, the hinge alignment, and the operator mount before recommending anything. A single residential driveway swing gate with a basic operator runs $2,800 to $5,500 in Sunnyvale, and that price is quoted and agreed in writing before we dig the first hole.
Pedestrian Gate Installation
Pedestrian gates on Sunnyvale ranch homes take a beating from the wet-winter-to-dry-summer cycle. Wood planks swell, warp, and pull away from hinge plates, leaving a gate that scrapes or won’t latch. We re-hang pedestrian gates with stainless hinges and sealed hardware, and if the wood is too far gone we quote a replacement that won’t warp the same way. A single pedestrian gate typically runs $1,100 to $2,600 depending on material and hardware, and homes in 94086 off El Camino Real with narrow 1960s side yards need gate widths kept tight so the swing still clears.
Sliding Gate Installation
Sliding gates are the workhorse of Sunnyvale’s 94089 business parks near Moffett Field, and the salt air out there is brutal on drive chains and rack-and-pinion hardware. A 1990s-era FAAC or LiftMaster slide operator that has been breathing bay air for 25 years will eventually seize or fault intermittently. We install slide gates with galvanized racks, stainless fasteners, and sealed loop detectors so they don’t fail the same way. Commercial sliding gates along Tasman Drive and Caribbean Drive start around $5,500 and climb with gate length, loop detectors, and card-reader wiring.
Are automatic gates in Sunnyvale required to have safety photocells?
Yes. Automatic gate operators in Sunnyvale are subject to California entrapment-protection requirements, which include safety photocells mounted at the entrapment zones. We install and set photocells on every powered gate we build or rebuild, and we test the reversing function before we leave. A gate that can’t reverse on obstruction is a gate that shouldn’t be running. Call (877) 610-2993 if you’re not sure yours is set correctly.
Can I install a solar gate opener on a driveway gate in Sunnyvale, or is the bay fog a problem?
Solar openers work in Sunnyvale but need to be sized for the fog. Northern Sunnyvale neighborhoods near the baylands get marine layer mornings that cut solar output, especially in winter. A badly-sized solar panel means a dead gate on exactly the morning you need to leave. We spec larger panels and lithium battery packs for Sunnyvale installs, and we’ll be honest if your specific driveway gets too much shade. Call (877) 610-2993 for a straight answer.
Gate Motor & Opener in Sunnyvale
Most gate motor failures in Sunnyvale come down to two things: age and salt air. In 94086 and 94087, the gate hardware was largely added in the 1980s and 1990s, which means the openers, hinges, and control boards are all reaching end-of-life on a similar schedule. In 94089 near the baylands, salt-laden marine air is quietly corroding chain drives and limit switches faster than it would a few miles inland. Our Gate Motor & Opener work starts with an honest diagnosis, not a sales pitch.
Motor Installation
Installing a new gate motor in Sunnyvale means matching the opener to the gate’s weight, swing direction, and exposure. A 300-pound iron gate on a home in 94087 needs a different motor than a 600-pound driveway gate on a larger lot off Fremont Avenue. We measure and spec the install before quoting the price, and we handle the power run, safety edges, and control panel setup so the install meets code the first time. Motor installation runs $1,100 to $2,800 depending on gate size and whether it’s a swing or slide application.
Motor Repair
Most gate motor repairs in Sunnyvale start with an honest diagnosis. Hal’s philosophy is simple: fix the motor you have unless it’s genuinely beyond saving. A gate motor repair typically runs $180 to $420 in Sunnyvale, with control board replacement at the lower end and full gear or drive-shaft replacement at the higher end. On-site welding lets us repair brackets, chain mounts, and gate frames in your driveway instead of hauling the gate to a shop.
Slide Motor
Slide motors in Sunnyvale take a beating in two distinct ways. In 94089, 1990s-era commercial FAAC and LiftMaster slide operators near Moffett Field often show seized chains from bay salt air combined with degraded in-ground vehicle loop detectors. That’s a compound failure needing both mechanical and low-voltage electrical diagnosis on the same call. In residential areas south of Central Expressway, slide gates are more often hurt by dry-season dust that clogs the rollers and overloads the motor. Linear motor rebuilds on commercial gates in the 94089 area often land between $650 and $1,400 due to salt-damage repairs and the need for new drive components.
How fast can you get to my gate in Sunnyvale?
We typically reach most Sunnyvale neighborhoods within 30 to 45 minutes, depending on traffic on Highway 101 and Wolfe Road. Same-day service is available for motor repairs, and emergency calls are answered 24/7 by a live person. Call (877) 610-2993 and we’ll give you a real arrival window, not an automated estimate.
What does a new gate motor installation include in Sunnyvale?
A full installation includes the motor and mounting hardware, control panel, safety edges, power run to the gate, and alignment of the gate itself so the motor isn’t working against a sagging frame. We also set the travel limits and test the obstruction sensors. The total price is quoted and agreed before work begins. Call (877) 610-2993 for a free estimate.
Gate Access Control in Sunnyvale
Gate access control in Sunnyvale runs into a problem most cities don’t have: salt air. The 94089 corridor near Moffett Field sits close enough to the South Bay that marine air drifts in and eats at drive chains, hinges, and low-voltage loop wiring faster than anything you’d see in Cupertino or Santa Clara. We’ve been out to corporate campuses in that corridor, and we’ve been to the 1950s ranch homes off El Camino Real in 94087. The failure modes are completely different, and so is the fix. Our Gate Access Control service covers both sides of that divide.
Keypad Entry
Keypads are the workhorse of Sunnyvale residential gates. The problem in older neighborhoods like the ranch tracts off Homestead Road and Hollenbeck Avenue in 94087 isn’t usually the keypad itself. It’s the wiring between the keypad and the opener, which has been sitting in conduit for 25 to 40 years. Water gets in, connections corrode, and suddenly codes don’t register. We trace the circuit before we sell you a new unit. A keypad replacement on a residential gate in 94087 typically runs $280 to $450 installed.
Card Reader
Card readers dominate the commercial side of Sunnyvale. Corporate campuses in 94089 near Moffett Field run badge-based access on sliding gates, and when those card readers fail, it’s almost always a power or wiring problem at the reader, not the card itself. A card reader replacement for a commercial gate in 94089 runs $400 to $700, depending on whether the reader is a standalone unit or part of a networked system. We handle the full circuit, including the low-voltage work, so you’re not calling a third party to finish the job.
Phone Entry
Phone entry systems let you buzz someone in from your cell. Sunnyvale HOAs in the newer townhome complexes along Lawrence Expressway and Wolfe Road use these heavily. Older phone entry boxes that rely on landlines are becoming a problem, because Sunnyvale households are dropping copper lines faster than phone companies can keep up. Phone entry system conversions from landline to cellular typically land between $350 and $600, and we get the call routing set up so the entry system works even when the landline is long gone.
Why do commercial slide gates near Moffett Field need more frequent access control service than residential gates in Sunnyvale?
Bay-salt air in the 94089 corridor corrodes drive chains, racks, hinges, and loop detector wiring at a rate you simply don’t see in 94086 and 94087, about two miles south. A commercial gate near Moffett that is 25 years old has been exposed to that air for its entire service life. Chain links seize, loop detector wiring degrades underground, and the compound failures mean these gates need inspection and service more often. Call (877) 610-2993 to schedule a check.
Why do HOA community gates in Sunnyvale need different access control service than older single-family gates?
HOA community gates in Sunnyvale, especially the newer townhome and condo complexes built in the 2000s and 2010s along Lawrence Expressway and Wolfe Road, run commercial-grade operators with hundreds of user codes, shared card readers, and sometimes video intercom integration. That’s a different animal from a single keypad on a 1990s ranch home. HOA systems need firmware updates, user database management, and entrapment-sensor recalibration to meet current safety code. Call (877) 610-2993 and we’ll walk you through what your system needs.
Gate Parts & Welding in Sunnyvale
If you’re searching for gate parts and welding in Sunnyvale, the short answer is this: most hinge, post, and rail repairs on residential gates run between $180 and $650, and our crew can usually have the parts pulled and the job scheduled within a day or two. We weld on site, which means your gate stays in your driveway instead of getting hauled to a shop. Our Gate Parts & Welding work covers everything from hinge swaps to full post replacements and custom fabrication.
Hinge Replacement
Worn or seized hinges are the most common gate failure in Sunnyvale’s older ranch neighborhoods. A 1980s-era steel gate in the 94086 tracts off Remington Drive typically has hinges that were never greased and have wallowed out their mounting holes. We replace them with heavier-barrel hinges, re-drill and sleeve the post holes, and realign the leaf so the operator isn’t fighting a bind. Hinge replacement in Sunnyvale runs $90 to $280 per hinge, installed and aligned.
Post Replacement
A gate sags in the hinge post, not in the middle, and that is where we start. In the clay-heavy soil common across Sunnyvale’s residential zip codes, posts set 30 years ago were often bedded in too little concrete and have since leaned out of plumb. We cut the old post at grade, auger a new footing at least 36 inches deep, set a heavier-wall post in fresh concrete, and rehang the gate. Post replacement in Sunnyvale generally runs $350 to $850 depending on post size and whether we’re reusing the existing panel.
Rail Repair
Bottom rails on older welded steel gates rust from the inside out, especially in northern Sunnyvale where bay-salt air accelerates oxidation on 94089 gates. If the rail is only surface-corroded, we weld in reinforcing plate and re-coat. If it’s structurally rotted, we replace the rail entirely and re-weld the pickets to the new member. Rail repair in Sunnyvale typically lands between $150 and $400 before coating. Show me the gate closing on its own and I’ll show you where it’s failing.
Why does my wooden gate in 94087 pull away from the hinge plates every winter?
Wet winters swell the wood, which breaks the screw bond between the plank and the hinge plate, and then the gate sags. The seasonal rhythm of wet winters followed by bone-dry summers in Sunnyvale makes this a repeating cycle on older 1980s-era wooden gates. The fix is through-bolting with backing plates and sealing the end grain, not just driving longer screws. Call (877) 610-2993 and we’ll get it to stop for good.
My 1990s swing gate in 94086 sags but the hinge welds look intact. What’s wrong?
The hinge post has likely leaned out of plumb in a shallow concrete footing, which is common in the 94086 ranch tracts where gates were added in the 80s and 90s without deep footings. The welded hinge is often still sound; the post underneath it isn’t. We re-bed the post in a deeper footing, then rehang and align the leaf. Call (877) 610-2993 for a free estimate on re-bedding that post.

What Sunnyvale Customers Say
"Operator had died and the manufacturer no longer makes the board. Rather than sell me a whole new system he found a compatible unit and adapted the mount. Saved me a great deal of money."
- Salvador Arredondo"Hundred and forty feet of cedar privacy fence, all posts set in concrete, all of it dead level on ground that is anything but. He walked the line with me twice before a single hole was dug."
- Judith Stallworth"Driveway gate had been dragging for two years and two other companies told me the whole thing needed replacing. Hal reset the posts, rehung it and it swings like it did when it went in. A fraction of the price of a new one."
