Calder Gate Repair is the dedicated gate specialist inside the Relay Home Co. family, serving San Marcos homeowners with background-checked technicians who arrive with a live, trackable ETA instead of a vague four-hour window. Call (903) 417-0793 and a real person answers, 24/7.

Why Calder Gate Repair Is San Marcos’s Preferred Gate Repair Company
We know San Marcos gates, and we know why they fail here specifically. This city sits on the Balcones Escarpment, where thin limestone soils sit over expansive clay. That means gate posts shift seasonally, and a gate that swung cleanly in July can bind or scrape after a wet winter. Our Gate Repair team diagnoses the underlying soil movement before touching the gate itself, because replacing a hinge on a leaning post just means you’ll be calling again in six months.
San Marcos homeowners tell us the same thing repeatedly: they’ve had contractors show up late, quote one number, then hand over a final bill that doesn’t match. We don’t do that. Every job gets a written price before any work starts, and the number on the invoice is the number you agreed to at the door. Every repair carries the 365-Day Done Right Promise in writing: if the repair fails within a year, we return and fix it free. No fine print, no re-quoting the same job.
Our technicians train on nine major gate opener brands including Linear, Viking, and Ghost Controls, so we’re not learning on your gate. And because calls route to a live dispatcher 24/7, you’re never leaving voicemails and hoping someone calls back. You’re talking to a person who can book the appointment, update you on arrival time, and answer basic troubleshooting questions on the spot.
Wood Gate Repair in San Marcos
Wood Gate Repair in San Marcos usually means a gate that’s sagging, scraping, or splitting, because wood absorbs the humidity this region throws at it and moves with every wet-dry cycle. When a wood gate drags across the driveway or won’t latch, the problem is rarely the gate itself. It’s the hinge post settling into clay soil, or a top rail that’s lost its structural connection to the frame. We repair or replace hinges, realign the gate, reinforce cracked rails, and reset posts where the soil has shifted.
Wood gate repair in San Marcos typically runs $150 to $400 depending on how far the gate has dropped and whether we’re rebuilding a section or resetting hardware. We quote that price in writing before anything gets touched.
Hinge and Post Reset Work
The most common wood gate failure we see in older San Marcos neighborhoods is a hinge post leaning under the gate’s weight. We dig out the footing, reset the post in new concrete with deeper embedment, and re-hang the gate so it clears the ground properly. If the post is sound, we may be able to sleeve and brace it instead of replacing it.
Gate Realignment and Hardware Replacement
A sagging wood gate puts strain on every hinge, latch, and drop rod. We re-level the gate, replace worn hinge pins or strap hinges, and adjust the latch so it lines up cleanly. Where the wood has split around mounting bolts, we reinforce the rail before reattaching hardware so the repair holds through San Marcos temperature swings.
Driveway Gate Repair in San Marcos
Driveway Gate Repair in San Marcos covers everything from heavy iron swing gates to chain-link slide gates on rural properties outside the city center. The older subdivisions and rural parcels around San Marcos have gates installed decades ago, often on undersized posts that now lean from expansive clay movement. Newer subdivisions have automated gates where the failures are more electronic: control boards, photocells, and limit switches.
Driveway gate repair in San Marcos usually costs between $200 and $500 for mechanical repairs, and opener-specific issues typically run $250 to $650 depending on the brand and which components failed. We tell you the number before we start.
Iron and Steel Driveway Gate Repair
In Sunset Oaks, we fixed a heavy iron double swing gate that had dropped and was scraping the driveway. The hinge post was leaning from soil movement, so we reset it with a deeper concrete footing, corrected the sag, and re-leveled the gate. We also replaced a failed LiftMaster gate operator control board and safety photocells, then tested auto-reverse per UL 325 standards. That job is a good snapshot of what San Marcos driveway gate repair actually looks like when you fix the root cause instead of patching the symptom.

Slide Gate and Track Repair
Slide gates on San Marcos properties pick up limestone grit and debris in the track, which wears rollers and causes jerky movement. We clean and repair tracks, replace worn roller assemblies, and adjust the chain or belt tension. Where the track or footing has settled, we re-level before touching the opener so the gate travels smoothly again.
Trusted Brands We Service in San Marcos
Calder Gate Repair trains on nine major gate opener brands, and the ones we see most often in San Marcos driveways are Linear, Viking, Ghost Controls, and DoorKing. That factory-level familiarity means we diagnose the actual fault instead of swapping parts on a hunch. We stock common control boards, photocells, remotes, and limit switches for these brands, so many San Marcos repairs happen on the first visit instead of waiting on an order. When a part does need ordering, we tell you the timeline and the cost before you commit to anything.
Common Gate Repair Problems We See in San Marcos Homes
- Hinge post shifting from expansive clay soil – San Marcos sits on the Balcones Escarpment where thin limestone over expansive clay makes posts move with every wet-dry cycle. A gate that scrapes in January may have a post leaning, not a hinge failure.
- Operator control board corrosion from humidity – Central Texas humidity and temperature swings cause condensation inside opener housings. Control boards corrode, relays fail, and gates stop responding to remotes or keypads.
- Photocell misalignment from gate sag or driveway settling – When the gate drops even half an inch, the safety photocells lose alignment and the gate either refuses to close or reverses for no reason. Realigning the gate usually fixes the sensor issue.
- Wood gate splitting at hinge and latch mounting points – Older wood gates in San Marcos split where hardware attaches because the wood dries and moves. We reinforce the rail before reattaching hinges so the repair doesn’t tear out again.

FAQs About Gate Repair in San Marcos
Most gate repair in San Marcos runs $180 to $500 before parts, with wood gate work on the lower end and opener repairs typically in the $250 to $650 range. The exact number depends on whether you’re dealing with a shifted post, a failed control board, or a full gate realignment. We quote every job in writing before any work begins, so you’ll know your number before we touch a bolt. Call (903) 417-0793 for a free estimate.
Yes, that’s a UL 325 safety compliance issue and you should have it addressed right away. Automated gates in San Marcos are required to meet UL 325 entrapment protection standards, which means the gate must reverse when it encounters an obstruction. A failed reverse function usually points to a bad photocell, a faulty limit switch, or a control board that’s no longer reading sensor inputs correctly. This needs a trained professional because the forces involved with a moving gate are genuinely dangerous. We diagnose and repair it properly, then test auto-reverse before we leave.
Yes, wood driveway gate repair is one of our most common jobs in San Marcos. We handle sagging gates, leaning hinge posts, split rails, latch failures, and gates that scrape because the post has settled into expansive clay. We reset posts in new concrete when the footing has shifted, reinforce wood around hinge mounting points, and re-level the gate so it clears the ground. Wood gate repair in San Marcos runs $150 to $400 before parts.
In San Marcos, a gate that keeps drifting or hitting the ground is usually sitting on a post that’s moved. The combination of thin limestone soil over expansive clay means wet winters cause posts to lean, which drops the gate and throws off the travel path. Less common causes include a slipping chain, a worn gear in the opener, or a limit switch that’s out of adjustment. We’ll diagnose the root cause instead of just cranking the gate back up, because without addressing the post movement it’ll sag again.
Yes, we install solar gate openers in San Marcos, including systems compatible with Linear, Viking, and Ghost Controls operators. A solar installation is measured, ordered, and scheduled, never promised same-day, because it involves panel placement, battery sizing, and wiring that have to be done correctly the first time. We provide a free site visit, size the system for your gate’s actual usage, and give you a written quote before any work starts. Call (903) 417-0793 to book a free measure.
