Gate Company in Cotati, CA
Calder Gate Repair handles gate repair, electric gate work, and opener replacement across Cotati, CA. Most jobs here involve swing gates on older ranch-style lots or newer sliding gates on compact parcels east of Highway 101. Cotati’s dry summers and wet winters put real stress on gate hardware, and we see the results every week. If your gate is stuck, noisy, or refusing to close, call (903) 417-0793 and we’ll get you a straight answer on what’s wrong and what it costs to fix.
Why Cotati Homes Are Different
Cotati’s housing stock runs older than much of Sonoma County. Many homes near downtown were built in the 1960s and 1970s, which means original gate posts, aging hinges, and opener wiring that predates modern safety standards. Those older installations often lack the photo-eye sensors now required on every automatic gate, so a repair here frequently involves bringing the whole system up to code, not just swapping a part.
The terrain matters too. Cotati sits on relatively flat ground compared to the hills around Sebastopol or east Santa Rosa, but the city gets steady afternoon wind off the coast range. That wind loads swing gates unevenly, wearing hinge bushings faster than in sheltered neighborhoods. Add in winter rain that swells wooden gate frames, and you get binding, dragging, and opener motors working harder than they should. We adjust for all of that on every Cotati job.
Some subdivisions, particularly newer developments on the north side of town, have HOA rules about gate appearance and opener type. If your community requires a specific opener brand or finish, tell us when you call. We work within those requirements daily and can usually match what the HOA expects without slowing the repair down.
Our Main Cotati Services
Cotati homeowners call us most often for two things: a gate that won’t open at all, and an opener that runs but doesn’t move the gate. Here’s how each one works in Cotati specifically.
Gate Repair in Cotati
A gate that drags, sags, or won’t latch is a security problem first and a convenience problem second. In Cotati, the usual culprits are rusted hinge bolts on older gates, posts that have shifted in the clay-heavy soil after a wet winter, or a wooden frame that has absorbed moisture and warped. We replace hardware with corrosion-resistant parts suited to Sonoma County weather and re-align the gate so the opener isn’t fighting the frame. Every repair includes a written price before we start and a 365-Day Done Right Promise. Gate Repair in Cotati

Electric Gate Repair in Cotati
Electric gate problems in Cotati range from dead control boards to safety sensors knocked out of alignment by wind or yard work. We diagnose the entire circuit, not just the obvious symptom, because a gate that stops midway is often a sensor issue, not a motor issue. Our techs carry replacement boards and sensors for major brands in the truck, so most electric gate repairs here are completed in one visit. Electric Gate Repair in Cotati

Gate Opener Repair in Cotati
Opener failures in Cotati often come down to two things: a capacitor or gear worn out from years of wind-loaded operation, or a control board damaged by winter moisture. We service openers from Linear, Viking, Ghost Controls, and DoorKing, among others, and we replace worn gears with factory parts, not generic substitutes. If your opener is older and parts are discontinued, we’ll walk you through replacement options with real prices before you commit. Gate Opener Repair in Cotati
