AfterFast, Reliable Gate Repair Across Redwood City
A gate that won’t open or close leaves your Redwood City home exposed, and a gate that reverses mid-cycle is a safety problem waiting to happen. Most gate repairs in Redwood City run $180 to $520, and our crews can typically reach your neighborhood the same day you call. Calder Gate Repair is the dedicated Gate Repair team inside the Relay Home Co. family, and we know which components fail first in Bay-adjacent humidity and salt air. Call (903) 417-0793 and a live person answers, 24/7, not a voicemail.
Why Calder Gate Repair Is Redwood City’s Preferred Gate Repair Company
We built our reputation in Redwood City by fixing what other companies patch. Homeowners from Redwood Shores to Emerald Hills call us because we show up with a written price, a live arrival time you can track, and a technician who actually knows your opener brand. Every Calder tech is background-checked, uniformed, and factory-familiar with FAAC, BFT, Linear, and Viking operators, so we do not waste your time guessing at the problem.
Our crews respond across Redwood City every weekday, and we hold the line on honest scheduling. You get a person on the phone, a window that means something, and before-and-after photos of the work. Nico Alvarez leads our Redwood City team and sets the standard himself: diagnose first, quote on paper, and never turn a gate job into a sales pitch for a full replacement unless the frame itself is shot.
We carry the 365-Day Done Right Promise in writing on every job. If a repair fails within a year, we return and make it right at no charge. No fine print. No re-inspection fee. That is the Relay Standard, and it is why a gate we fix in Redwood City stays fixed through the next Bay winter.
Wrought Iron Gate Repair in Redwood City
Wrought iron gate repair in Redwood City almost always comes down to rust where the gate meets the hinges, or a bottom rail that has thinned out from years of Bay moisture. The marine-influenced air off the Bay keeps humidity high enough that untreated steel frames and hinges corrode faster than in inland Peninsula cities like Menlo Park. A repair that only replaces a rusted hinge without addressing the frame’s finish will fail again within a season.
Pricing for wrought iron work in Redwood City typically runs $260 to $620, depending on how much metal needs to be cut out and welded back. We weld, grind, prime, and repaint so the repair disappears into the original finish. When the hinge post itself has shifted from wet winter soil, we dig the footing, reset the post in concrete, and rehang the gate so it swings true.
Hinge replacement and post resetting
Hinges on iron gates carry the entire weight of the leaf, and in Redwood City’s damp air they bind, squeal, and eventually tear loose from the post. We replace welded barrel hinges and surface-mounted strap hinges, then reset posts that have leaned out of plumb. If the post is cracked at the weld point, we reinforce the plate rather than screwing into weakened metal.
Rust repair and repainting
Salt-laden air accelerates rust on iron gate frames, and Redwood City homes near the sloughs get it worst. We grind rust back to clean steel, treat the surface, and apply a two-part industrial primer before the finish coat. A gate that looks right but is not treated underneath will blister within months, which is why we only do full-surface prep, never a scuff-and-spray.
Metal Gate Repair in Redwood City
Metal gate repair in Redwood City covers steel and aluminum driveway gates, pedestrian gates, and the rack-and-pinion tracks on slide gates. The most common call we get is a gate that has started sagging, scraping the ground, or binding mid-travel because the post footing shifted during a wet winter. Low-lying areas near the Bay hold water in the soil, and that saturated ground lets posts creep out of alignment.
Most metal gate repairs in Redwood City run $180 to $480 before parts. Straightening a bent frame, welding a cracked joint, or replacing a broken wheel on a slide gate all fall in that range. When the post is the problem, the job costs more because we excavate, pour a new concrete footing, and let it cure before rehanging the gate.
Gate realignment and frame welding
A metal gate that scrapes the driveway is not just noisy, it is working against its own motor. We realign the gate on its hinges, shim or replace hinge plates, and weld cracks before they spread through the frame. On slide gates, we check the track wheels and rack alignment, because a misaligned rack wears out the drive gear on the opener.
Track and roller replacement
Cantilever and V-track slide gates depend on rollers that take a beating from Redwood City’s damp air and debris from overhanging oaks. We replace seized rollers, realign tracks, and adjust the rack so the gate does not chatter. This is the kind of repair that prevents a $200 roller from becoming a $1,500 opener replacement.
Trusted Brands We Service in Redwood City
Our techs work on FAAC, BFT, Linear, and Viking operators every week, and we keep common boards, limit switches, and photocells on the truck so we do not have to run back to the shop mid-repair. Whether your Redwood City gate runs on a chain-drive Viking or a hydraulic FAAC, we diagnose by the symptoms, not by guesswork. If the part is not on the truck, we order it overnight and keep you posted by text, because waiting silently is not how we work.
Common Gate Repair Problems We See in Redwood City Homes
- Fogged or corroded safety photocells: Constant Bay moisture condenses on the lens, so the opener thinks there is an obstacle and refuses to close. We clean or replace the photocell and verify the reversal test passes before we leave.
- Rusted hinge posts on swing gates: Wet winter soil saturates the footing, the post leans, and the gate sags until it drags. We reset the post in concrete and rehang the leaf so the weight is distributed correctly.
- Rack-and-pinion misalignment on slide gates: Salt air corrodes the rack bolts and the gate starts jumping teeth, which grinds the drive gear. We replace the rack sections, reset the alignment, and test the motor load.
- Intermittent reversal failures from board corrosion: Opener control boards sit in plastic housings that trap humidity near Redwood Shores. A board with corroded terminals will reverse mid-cycle, then work fine an hour later. We test under load, not just on the bench.

FAQs About Gate Repair in Redwood City
A sag correction is enough when the hinge post is still plumb and the hinges themselves are worn or loose. A new footing is required when the post leans visibly, the gate scrapes the ground on one side, or the post wobbles when you push it. In Redwood City’s low-lying areas near the Bay, saturated winter soil shifts posts out of plumb, and shimming a gate onto a leaning post just moves the strain to the opener. We check the post with a level before quoting either job, so you only pay for what actually needs to be done. Call (903) 417-0793 and we will tell you straight.
Yes, absolutely. That reversal feature is what keeps a closing gate from crushing a person, a pet, or a car, and a gate that stops reversing when it meets resistance is a serious safety failure. In Redwood City, the usual culprits are a corroded control board, a fogged safety photocell, or a misadjusted limit switch – the small sensor that tells the gate when to stop. Do not run the gate until a tech has tested the reversal under load and verified the safety edges. Call (903) 417-0793 and we will come out, diagnose it, and give you a written price before any work starts.
We service FAAC, BFT, Linear, and Viking operators, plus five more common brands, which covers virtually every opener a Redwood City homeowner is likely to own. Our techs are factory-familiar with each brand’s board layouts, limit switch positions, and failure modes, so we do not need to look up the manual mid-repair. If your opener is from a brand we do not stock parts for, we will tell you before we drive out, not after.
Most hinge, photocell, and limit switch repairs are finished in 60 to 90 minutes on site. A rust repair with welding and repainting takes most of a day, including cure time between coats. Hinge post resetting with a new concrete footing takes a day to excavate, set, and pour, then one to two days of cure time before we rehang the gate. You will know the timeline before we start, because it is written on the quote.
Yes, and more than you likely realize. Bay-adjacent humidity corrodes gate operator control boards and safety photocell lenses faster than inland Peninsula cities, and winter rain saturates the soil around post footings in low-lying areas. We recommend a visual check of hinges, posts, and safety edges every spring, before the dry season sets in. It costs less than a repair and catches a leaning post before it takes the opener with it.
