Gate Company in Foster City, CA
Calder Gate Repair is the gate company Foster City homeowners call when a driveway gate stops opening, a keypad locks them out, or an opener starts grinding. If you’re searching for a home gate specialist, most jobs here come down to one of three fixes: a gate off its track, an electric system that lost power or signal, or an opener motor that quit. We’re part of the Relay Home Co. family, and every Foster City job comes with a written price before any work starts, a 365-Day Done Right Promise, and a live person on the phone twenty-four hours a day. Call (903) 417-0793 for a free estimate.
Why Foster City Homes Are Different
Foster City was built on engineered landfill along the San Francisco Bay, which means two things for gate work: soil settles and shifts, and lots are tighter than in the East Bay hills. Gates that worked fine five years ago drift out of alignment as the ground beneath the posts moves. Most properties here are single-family homes from the 1960s through 1980s, many with original driveway gates and openers that predate smartphone integration. Foster City is also a planned community with active homeowner associations, especially in neighborhoods like the Islands and the Gables, where exterior changes often need HOA sign-off before a new gate can be installed. Salt air is a constant: hinges, brackets, and control boards near the water corrode faster than they do ten miles inland. And because many lots back onto lagoons, access panels and power runs sometimes sit in damp, hard-to-reach spots. None of this is exotic, but it does change how we diagnose and repair.
Our Main Foster City Services
Two service calls dominate our schedule in Foster City: mechanical gate failures and opener problems. Here’s what each involves.
Gate Repair in Foster City
A sagging, stuck, or dragging gate in Foster City is usually a combination of settled posts, corroded hinges, and a set of wheels or rollers that have worn down on one side. We straighten the frame, replace what’s pitted or seized, and reset the travel so the gate doesn’t bind at the latch. On lagoon-facing properties we take extra time with rust removal and marine-grade hardware where the original has failed. Most Gate Repair in Foster City calls are completed in a single visit because the job is mechanical: the gate itself, not the electronics.

Electric Gate Repair in Foster City
Electric gate problems in Foster City tend to be either interrupted power to the motor, a damaged or severed loop wire under the driveway, or corrosion inside the control box. Water intrusion is the recurring theme, especially on older installs where the cabinet gasket has hardened and cracked. We trace the circuit, test the safety edges and photocells, and replace boards or wiring as needed. Full details live on our Electric Gate Repair in Foster City page.

Gate Opener Repair in Foster City
When the opener hums but the gate doesn’t move, or the remote works only from three feet away, Foster City homeowners are dealing with a failed capacitor, stripped gear, or a receiver board that’s lost its range. We service LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule and stock common parts locally so most opener repairs don’t wait on a shipment.
