Gate Company in San Lorenzo, CA
Calder Gate Repair is the San Lorenzo gate company homeowners call when a slide gate won’t close, an opener hums without moving, or a safety sensor keeps tripping for no reason. Gate work in San Lorenzo has a few quirks: many homes here were built in the 1940s and 1950s, driveways are narrow, and a lot of gates sit close to the house, which changes how we approach motor mounting and noise. We quote every San Lorenzo job in writing before any bolt is turned. Call (903) 417-0793 and a live person answers, day or night.
Why San Lorenzo Homes Are Different
San Lorenzo’s housing stock leans older, with a large share of single-story ranch homes on flat, grid-like streets. That flat terrain is good for gate automation because the track or wheels don’t fight a slope, but the older driveways present their own issue: concrete that has settled or cracked over decades can throw a gate out of level. When a gate sits even an inch off, the opener has to work harder, and the limit switch – the small sensor that tells the gate when to stop – gets out of sync. We see that pattern regularly in San Lorenzo, and it’s usually fixable in one visit.
The mild Bay Area climate means rust is less aggressive here than in coastal fog zones like Pacifica, but the winter rain still finds its way into poorly sealed control boxes. Homes with mature landscaping, especially on streets like Bockman Road and Via Arroyo, often have gates shaded by trees, so we check for leaf debris in the track and moisture inside the housing. If your San Lorenzo property is in an HOA, the association may have rules about gate style and opener placement, and we’re used to working within those requirements.
Our Main San Lorenzo Services
Most San Lorenzo calls fall into one of two buckets: the gate itself won’t move properly, or the electric opener that drives it has failed. Each service has its own San Lorenzo page with deeper detail, pricing, and what to expect.
Gate Repair in San Lorenzo
A sagging or stuck gate in San Lorenzo usually comes down to three things: a bent hinge, a wheel that’s worn flat on one side, or a post that shifted out of plumb. On older ranch homes the gate post is sometimes set directly into aging concrete, and once it moves, the whole gate binds. We straighten, reinforce, or replace what’s needed and adjust the gate so it swings or slides the way it did when it was new. Full details are on the Gate Repair in San Lorenzo page, including what we check on every visit.

Electric Gate Repair in San Lorenzo
Electric gates in San Lorenzo fail most often at the power source or the safety loop: a tripped GFCI, a wire chewed through by a rodent, or a loop detector that no longer senses a car pulling up. The flat residential streets of San Lorenzo mean many gates are close to the house, so we can often diagnose the electrical fault quickly without running long conduit. For the full picture – from capacitor failures to keypad wiring – see our Electric Gate Repair in San Lorenzo page.

Gate Opener Repair in San Lorenzo
When the opener is the problem, the gate usually makes noise but doesn’t move, or moves a few inches and reverses. In San Lorenzo we work on openers from LiftMaster, FAAC, BFT, Linear, Viking, and others, and we keep common control boards, remotes, and limit switches on the truck so a first-trip fix is realistic. If your opener is older and parts are discontinued, we’ll tell you straight and give you options. See Gate Opener Repair in San Lorenzo for what a typical opener repair covers in this area.
