Calder Gate Repair knows San Ramon’s gates. The inland hills of Contra Costa County bring summer heat spikes into the 90s and 100s, followed by wet, soil-saturating winters. That cycle hits gate systems hard, warping wood panels, shifting hinge post footings, and stressing operator control boards. We diagnose quickly, fix the root cause, and stand behind it for a full year.
Why Calder Gate Repair Is San Ramon’s Preferred Gate Repair Company
We’re the dedicated gate repair specialist inside the Relay Home Co. family, which was established in 2009 and operates with each location independently owned and run. For San Ramon homeowners, that means direct accountability: our lead here is Nico Alvarez, and he’s the one making sure your repair is done right. We don’t hand you to a chain. We hand you a name, a phone number, and a guarantee.
Every San Ramon job comes with the 365-Day Done Right Promise in writing. If the repair fails within a year, Calder returns and makes it right, no charge for the second visit. Ever. We also put the price in writing before any work starts. No surcharge at the door, no tag-on after the fact. That’s how we operate with every homeowner from Dougherty Valley to Gale Ranch.
Our technicians are background-checked and arrive in uniform with a live, trackable arrival time. Not a four-hour window. A real ETA you can follow on your phone as the truck moves through the 680 corridor and into your neighborhood. You’ll know who’s coming, when they’ll arrive, and what the job will cost before we touch the first hinge.
Wood Gate Repair in San Ramon
Wood Gate Repair in San Ramon is a year-round service because our climate is brutal on wood. Summer heat dries panels and opens seams; winter rain swells them right back. The result is a gate that drags, sticks, or pulls its hinge screws loose. Most of the wood gate work we do in San Ramon involves re-hanging panels, replacing rotted rails, and adding proper cross-bracing so the gate doesn’t rack again in the next wet season. Expect a typical wood gate repair in San Ramon to run $250 to $650 depending on how much of the panel and hardware needs attention.
Seasonal Swelling and Panel Drag
When a wood gate absorbs winter moisture, it swells toward the gate operator’s rack and pinion. That adds drag the motor fights every cycle until something gives. We plane back the binding edge, treat exposed wood, and adjust the operator travel so the gate doesn’t strain itself through January and February.
Hinge Post Settlement Repairs
In San Ramon’s expansive clay soils, the hinge post is usually the real culprit. Soil movement shoves the post out of plumb, the panel tilts, and homeowners assume the gate itself is wrecked. Often it isn’t. We’ve re-poured dozens of footings where the wood panel stayed solid and the post just needed resetting.
Driveway Gate Repair in San Ramon
Driveway Gate Repair in San Ramon covers everything from a gate that scrapes the driveway to an opener that trips and reverses for no reason. These gates are heavy, sometimes 300 to 500 pounds for an iron or steel build. When a hinge post settles, that weight drives the panel into the paving, and the opener’s motor burns out trying to compensate. The good news: most driveway gate failures we see here are repairable without replacing the whole unit. Typical repairs run $350 to $1,100 depending on the opener, the hinge hardware, and how far the post has drifted.
Realigning Heavy Panels
A driveway gate that drags at the latch side is almost always a geometry problem, not a power problem. We reset the post alignment and hinge bearings until the gate swings freely, then balance the opener so the motor works inside its rated load. That’s what stops the grinding and the electrical trips.

Opener Motor and Drive Rail Strain
San Ramon’s heat spikes take a toll on operator control boards and battery backups. When the motor strains against a misaligned panel, the control board’s logic sees an obstructed gate and reverses. We check motor current draw, limit switches, and backup batteries as one system, not three separate guesses.
Trusted Brands We Service in San Ramon
Our technicians are factory-familiar with nine major opener brands, including Linear, Viking, DoorKing, Ghost Controls, LiftMaster, FAAC, BFT, Elite, and Mighty Mule. For San Ramon customers, that means we can service what’s already on your gate instead of forcing a replacement. We keep common Linear and DoorKing parts stocked locally because those two show up all over the neighborhoods along Bollinger Canyon Road and Norris Canyon. When your Viking or Ghost Controls board fails after a heat spike, we’re not waiting a week on a distributor to ship it.
Common Gate Repair Problems We See in San Ramon Homes
- Swing gate sag traced to post footing movement. San Ramon’s expansive clay soils absorb winter rain and push against shallow footings. The panel tilts, the latch misses, and the gate drags. We pull the post and re-pour at proper depth to stop the cycle.
- Control board and battery failure after summer heat spikes. Opener enclosures trap 100-degree heat, and boards inside cook slowly. Keypad and loop detector triggers drop out. The fix is a new board plus a relocated or vented enclosure so it doesn’t happen again in August.
- Wood panel swelling into the drive rail. After wet winters, panels gain a quarter inch or more and jam against the rack and pinion. The motor overworks, the thermal overload trips, and eventually the motor dies. We plane, seal, and adjust the operator travel.
- Safety photocells knocked out of alignment. On sloped driveways common in the Bollinger Hills and Crow Canyon areas, a gate’s concrete pad shifts a half inch and suddenly the photocells can’t see each other. The gate refuses to close. A quick realignment and checked mounting usually fixes it.

FAQs About Gate Repair in San Ramon
Yes, in most cases. A sagging swing gate here is usually caused by the hinge post settling in expansive clay soil, not by a ruined panel. We pull the post, re-pour the footing at proper depth, realign the hinges, and reset the opener. Your gate gets a new lease on life. If the panel is rotted or cracked beyond repair, we’ll tell you and show you why before quoting anything. Call (903) 417-0793 for a free assessment.
A proper automatic gate installation includes concrete footings sized for the post depth, branch circuit power run to the opener, safety photocells on both sides, entrapment protection, and a full reversal test. The gate must reverse off an obstruction at multiple points along its travel, and the keypad or entry system has to be programmed and tested. That work takes a day or two and gets scheduled, not rushed. We’ll give you a written breakdown of scope and materials before any work starts.
Yes. Our technicians are factory-familiar with LiftMaster, FAAC, and DoorKing, plus six more major brands: BFT, Linear, Viking, Ghost Controls, Elite, and Mighty Mule. We carry common parts for Linear and DoorKing locally because those show up most often in San Ramon. That means faster turnaround when your board fails and we can start the same day rather than waiting on a distributor. Estimates are free at (903) 417-0793.
Most hinge, alignment, and board replacements finish the same day. Post resetting and footing work takes one full day because the concrete needs time to cure before the panel goes back on. If you call before noon, we can usually be at your home in San Ramon within a few hours with a trackable ETA. Same-day scheduling covers most repairs, not full installations, which we schedule and scope properly. Call (903) 417-0793 and we’ll give you a straight answer on your specific gate.
Yes. Automatic gate operators in California must detect obstructions and reverse. That means functioning safety photocells across the gate opening, an audible alarm or warning device in some configurations, and consistent reversal under load. If your gate forces through an obstruction or the photocells are zip-tied out of the way, it’s not compliant and it’s a hazard. We test every gate’s safety system on every repair and will not leave a gate in service that could entrap someone. Call (903) 417-0793 and we’ll check yours as part of any visit.
