AfterFast, Reliable Gate Repair Across Sunnyvale
Gate repair in Sunnyvale usually costs between $180 and $650 depending on whether we’re pulling a sagging hinge post back into line, replacing a seized drive chain, or retrofitting an old operator with modern safety edges. Most repairs in Sunnyvale happen same-day or next-day because we keep the common parts on the truck. Call (877) 610-2993 and a real person answers, any hour. We’ve worked on gates across every Sunnyvale zip code long enough to know which failures show up in which neighborhoods before we even park the truck.
Sunnyvale isn’t one gate market, it’s two. The residential streets of 94086 and 94087 are full of 1950s through 1970s ranch homes where driveways and side-yard gates got added as aftermarket security upgrades in the 1980s and 90s. That hardware is now 25 to 40 years old and failing in predictable patterns: rusted hinge posts, sagging panels, worn latch hardware. Then you have the commercial corridor in 94089 near Moffett Field, where automated slide gates, card readers, and vehicle loops run daily from 6 a.m. to 8 p.m. and wear out on a completely different clock. This page tells you straight what breaks, what it costs to fix here, and when a retrofit beats a replacement.
Why Gatewood Fence & Gate Is Sunnyvale’s Preferred Gate Repair Company
Hal Gatewood started this shop in 2001 and his name is still on the door and on every invoice. We’re not a franchise, not a dispatch service, and not a call center three states over. When you call about a gate in Sunnyvale, the person who answers understands what a salt-seized FAAC operator in 94089 looks like because we’ve cut more than a few open. We don’t haul your gate off to some central shop. We weld on site, in your driveway, and the gate never leaves your property.
The 90-Day Done Right Promise is written on every job we do in Sunnyvale. If something isn’t right, you call and we come back. No runaround, no fine print, no “that part isn’t covered.” One call brings Hal back. We also answer the phone around the clock with a live person, so when a gate motor dies at 8 p.m. and your car is stuck inside, you get a human voice and a plan, not voicemail.
We carry parts for LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. That matters in Sunnyvale because the commercial operators near Moffett Field skew toward FAAC and LiftMaster, while the residential retrofits in 94086 and 94087 run heavily on Linear, Viking, and Ghost Controls. Having the right board, chain, and safety edge on hand means we usually finish the repair in one trip.
Our Gate Repair Services in Sunnyvale
Electric Gate Repair
Electric gate operators in Sunnyvale fail in two distinct ways. In 94089, salt-laden air from the baylands works into circuit boards, terminal strips, and limit switches on older commercial units until the gate simply refuses to move. In the residential zips, the more common failure is a control board that’s still trying to run a 1995-era motor and no longer understands its own safety logic. We diagnose on site, tell you honestly whether the board can be rebuilt or should be replaced, and quote the work before we touch a wire.
Automatic Gate Repair
An automatic gate that opens halfway and reverses, or one that trips the breaker when the sun hits it, usually points to a worn gear box, a failing capacitor, or a photo-eye that’s lost its alignment. In Sunnyvale, we see a lot of automatic gates on HOA-managed condo and townhome complexes built during the 2000s tech boom. Those entry gates cycle hundreds of times a day and need commercial-grade service, not a handyman with a multi-meter. We quote the repair, agree on the price, and do the work without changing the number on you.
Hinge & Post Repair
The hinge post is where most residential gate problems actually live. A gate sags in the hinge post, not in the middle, and that’s where we start. In Sunnyvale’s 94086 and 94087 neighborhoods, decades of wet winters followed by bone-dry summers have left many original wood posts and older steel posts rotted or rusted at ground level. We cut out the bad post, set a galvanized footing, and rehang the gate so it closes true. Fix the panel without the post and you’ll fix it twice.
Gate Realignment
Realignment handles the gate that still has good hardware but no longer sits square in its frame. We see this constantly on older decorative iron gates in Sunnyvale where, over time, the post has shifted out of plumb. We bring the post back, reset the hinges, and restore the proper reveal so the latch engages cleanly. This is often a same-visit fix and it’s the repair most national companies skip because there’s less margin in it than selling you a new gate.

Common Gate Repair Problems We See in Sunnyvale Homes
- Rusted hinge posts in 94086 and 94087. The original ranch-style homes from the 1950s to 1970s grew gates later, and those aftermarket installs rarely used galvanized posts. Wet winters and dry summers at the soil line mean the post rots or rusts through right where the gate hangs its full weight.
- Salt-seized operators and loop detectors in 94089. The baylands air near Moffett Field carries salt that doesn’t show up on the inland side of the city. We have seen 1990s-era slide operators where the drive chain is stiff with corrosion and the in-ground loop has failed in the same month. It’s a compound failure requiring mechanical and low-voltage work in one visit.
- Obsolete control boards with no safety edge. A surprising number of Sunnyvale residential gates from the 1990s are still running original control boards with no photo-eye protection and no auto-reverse. The board works until it doesn’t, and when it doesn’t, the right fix is usually a retrofit board that meets current UL 325 safety logic rather than trying to revive the antique.
- Warped wood gates pulling from hinge plates. The older wood gates across town swell during wet winters and bake dry in summer. The planks pull away from the hinge plates, the gate drops, and the latch stops lining up. We realign and refasten, and if the wood is too far gone, we’ll tell you that plainly before quoting a replacement.

FAQs - Gate Repair in Sunnyvale
Because 94089 sits right against the South Bay baylands, and the air off the water carries salt that settles on exposed iron and steel. In our experience, a set of iron hinges in the Moffett Field corridor will show noticeable pitting years before the same hardware a few miles east in San Jose. The salt works into the bearing surfaces and the gate starts to grind, sag, and bind. We use galvanized or stainless hardware on any replacement in that part of Sunnyvale. Call (877) 610-2993 if your gate is starting to fight back when you open it.
In most cases, yes. A 1990s operator with a good motor and gear assembly can usually be fitted with a modern control board, photo-eye sensors, and an auto-reverse function that meets current safety logic without replacing the entire unit. Hal’s crew has retrofitted dozens of older operators in the 94086 and 94087 neighborhoods so homes keep their original gate while getting modern protection. The right answer depends on the board’s compatibility and the motor’s condition. Call (877) 610-2993 and we’ll give you a straight answer after one look.
Sunnyvale has a wet-winter, dry-summer cycle that swells wood planks when the rain comes and shrinks them hard when the summer heat hits. Older wooden gates built in the 1980s and 90s often weren’t sealed on the cut ends, so the grain absorbs moisture unevenly and the planks eventually pull the screws right out of the hinge plates. We fix it by refastening with structural screws and realigning the gate, and if the wood is too far gone we’ll say so before spending your money. Call (877) 610-2993 and we’ll look at it free.
Not necessarily. A seized drive chain on a commercial slide gate near Moffett Field usually means the chain, sprockets, and sometimes the idler bearings have been corroded by baylands salt. The operator’s motor and gear assembly are often still fine. We replace the chain and sprockets, free up the drive, and test the unit before recommending anything bigger. If the control board and loop detector are also failed, which is common in that zip, we’ll quote the combined repair honestly and do it in one visit. Call (877) 610-2993 for a quote.
If the gate sags more at the latch than at the hinge end, the post itself is moving. Push on the post at ground level. If it flexes or you can rock it, the wood or steel is compromised below the soil line. That’s a post repair, not a realignment. In Sunnyvale’s older ranch-home neighborhoods, this is the single most common gate failure we find. Fix the panel without the post and you’ll fix it twice. Call (877) 610-2993 and we’ll come out and tell you which one you have.
