Why Calder Gate Repair Is Kentfield’s Preferred Gate Repair Company
Nico Alvarez leads our Gate Repair team, and he’s built Calder around one idea: Kentfield homeowners shouldn’t have to gamble on whether a gate tech will show up, what they’ll charge, or whether the fix will hold. We’re part of the Relay Home Co. family, founded in 2009, and every Kentfield customer gets the same three guarantees in writing: a price before work starts, a written guarantee on every repair, and a free second visit if the repair fails within 365 days.
Our technicians arrive in uniform, background-checked, with a live arrival time you can track from your phone. No four-hour windows. No wondering if anyone’s coming. Kentfield residents regularly tell us the transparency is what sold them, because gate repair has a reputation for vague quotes and surprise invoices. We don’t do that. The number you agree to is the number on the invoice.
We know the gate opener brands installed across Kentfield’s long driveways, and we carry the parts that fail most often so you’re not waiting on a distributor to ship from out of state. When a LiftMaster or FAAC board goes down on a Saturday, we don’t put you off until Tuesday.
Metal Gate Repair in Kentfield
Metal Gate Repair in Kentfield covers steel and aluminum driveway gates, pedestrian gates, and the frames they hang from. In this area, the most common failures we see are rust at the hinge welds, sagging caused by post movement, and binding where the gate drags on the uphill side of a sloped driveway. Repair work typically runs $220 to $650 on Kentfield jobs, depending on whether we’re cutting out rusted sections, reinforcing posts, or realigning the entire frame.
Hinge And Post Reinforcement
Kentfield’s clay-heavy soil expands when wet and contracts in summer. That movement gradually tilts gate posts, especially on sloped lots where runoff pools at the base. We reset posts in concrete footings, weld or bolt reinforcement plates, and shim hinges until the gate swings true.
Weld And Rust Repair
Steel gates near creeks and shaded lots in Kentfield collect moisture faster than you’d expect. We grind out compromised metal, weld in new sections where the frame is still solid, and treat the surface so rust doesn’t return in six months.
Wood Gate Repair in Kentfield
Wood Gate Repair in Kentfield is a different trade than metal work, because wood moves with humidity and rain. Redwood and cedar gates are common on Kentfield properties, and they sag when hinge fasteners pull loose from softened wood or when the frame itself warps. Expect to pay $180 to $400 for most wood gate repairs locally, more if we’re rebuilding the frame entirely.
Sag Correction And Hinge Reset
A sagging wood gate in Kentfield usually isn’t just a hinge issue. The post may be rotting below grade, the gate frame may be out of square, or the previous hardware was undersized for the gate’s weight. We address the cause, not just the symptom, so the gate doesn’t droop again after the first wet season.

Frame Rebuild And Hardware Upgrade
When a wood gate frame is too far gone to hold screws, we rebuild it with pressure-treated lumber and stainless hardware. This is especially common on older Kentfield properties where gates have been patched for years rather than properly repaired. You get a written quote before we touch anything.
Trusted Brands We Service in Kentfield
We’re factory-familiar with nine major gate opener brands, and around Kentfield the ones we service most are Linear, Viking, and DoorKing on the residential side, with Ghost Controls showing up frequently on newer lightweight gates. If you’ve inherited an older Linear swing opener or a Viking slide unit from a previous owner, we know how to source the correct boards, remotes, and limit switches instead of selling you a full replacement you don’t need. We keep local parts stock for Kentfield service calls so repairs don’t stall waiting on freight. When your gate opener quits, you want a tech who recognizes the unit the moment they see it.
Common Gate Repair Problems We See in Kentfield Homes
- Hinge post rot and shifting. Kentfield’s clay soil and winter groundwater move posts just enough that gates bind, sag, or scrape against the driveway. We reset the footing and reinforce the post rather than just cranking the hinges again.
- Operator failure on long, sloped driveways. When power lines from the house are undersized for a LiftMaster or FAAC unit, the operator overheats and burns boards. We check the juice before we blame the motor.
- Safety photocell misalignment. Wooded lots drop debris onto gate tracks and sensors, and a single well-placed branch can trip a reversal. Random gate reversals in Kentfield are often just misaligned or dirty photocells.
- Rack and pinion wear on slide gates. The rack and pinion on a slide gate off Sir Francis Drake Blvd. grinds down faster when the gate is forced against a warped track. Regular adjustment beats a $1,000 replacement.

FAQs About Gate Repair in Kentfield
Kentfield’s clay-heavy soil expands when wet and shifts the gate post below ground, so hinge adjustments only mask the real problem. The fix is resetting the post in a deeper concrete footing, sometimes with steel reinforcement, then rebuilding the hinge mount. Call (903) 417-0793 and we’ll confirm it with a site visit. Estimates are free.
Your gate needs UL 325-compliant safety features: working photocells, reversal on obstruction, and proper force settings. We test every gate we repair in Kentfield for these requirements and document it in the repair report, so you have a paper trail if you ever need it. If we find a gap, we’ll fix it and show you the test results.
We service Linear, Viking, DoorKing, Ghost Controls, LiftMaster, FAAC, BFT, Elite, and Mighty Mule. Most Kentfield homes have one of the first four, and our techs know the failure points of each. For an exact diagnosis and quote, call (903) 417-0793.
Kentfield’s tree canopy makes solar panel placement tricky on some lots. Yes, we install solar operators, usually on the sunnier side of Sir Francis Drake Boulevard or on properties with clear southern exposure. We’ll confirm panel position and output during a free site visit, and you’ll get a written quote before any installation starts.
On Kentfield properties it’s usually a debris-covered or misaligned safety photocell on wooded lots, or the force setting is too sensitive after a post shift. We check the sensors first, then the limit settings, then the board. Call (903) 417-0793 for a free estimate and a trackable arrival time.
