Fast, Reliable Gate Repair Across San Antonio
A gate that won’t open, drags on the ground, or triggers its safety sensor for no reason is more than an annoyance in San Antonio. It’s a security gap. Most gate repairs in San Antonio run between $175 and $520 before parts, and the biggest cost driver is usually what caused the failure in the first place: a shifting post, a fried control board, or heat-damaged wiring. We’re Calder Gate Repair, part of the Relay Home Co. family established in 2009, and we handle Gate Repair jobs across San Antonio with written pricing before any work begins. Call (903) 417-0793 and you’ll reach a live person, not a voicemail.

Why Calder Gate Repair Is San Antonio’s Preferred Gate Repair Company
San Antonio homeowners don’t want a vague four-hour window. They want to know who’s coming and when. That’s the Relay Standard: a live, trackable arrival time sent to your phone, a background-checked technician in uniform, and a digital invoice you pay from a link. Nico Alvarez runs our San Antonio team, and he’s built a crew that treats every gate like it guards their own home.
We repair gates in neighborhoods across the city, from Shavano Park and Stone Oak down to Mission del Lago and Alamo Ranch. That matters because gate failures here aren’t abstract. The clay soil under a Stone Oak driveway behaves differently than the limestone shelf near Government Canyon. Knowing the difference changes how we fix a post footing. Our Google reviews from San Antonio customers consistently mention two things: the technician showed up on time, and the final invoice matched the quote. We’re not interested in winning on vague promises. We win on the 365-Day Done Right Promise, stated in writing on every job. If the repair fails within 365 days, we return at no charge. That’s not a sales line. It’s the guarantee printed on your invoice.
Commercial Gate Repair in San Antonio
Commercial Gate Repair in San Antonio covers a different animal than residential work. Think slide gates at distribution centers off I-35, swing gates at apartment complexes near UTSA, and cantilever gates at storage facilities along Loop 1604. These systems run harder: more cycles per day, heavier panels, and operators that get hot. A commercial slide gate repair in San Antonio typically runs $280 to $700, and full operator replacement on a commercial system often lands between $1,800 and $3,400 depending on the opener brand and panel weight.
Heavy-Cycle Operator Service
Commercial operators on gates that cycle dozens of times daily wear out limit switches, contactors, and drive belts on a predictable schedule. We keep common DoorKing and Elite parts stocked for San Antonio commercial accounts, which cuts downtime to hours instead of days.
Safety Loop and Photocell Checks
UL 325 entrapment protection is non-negotiable on commercial automatic gates. We test and replace inductive loops and photocells regularly, because in high-traffic commercial settings these components fail quietly until someone’s car hood is under the gate.
Iron Gate Repair in San Antonio
Iron Gate Repair in San Antonio usually comes down to two forces working against each other: San Antonio’s expansive clay soil and the weight of a solid wrought-iron panel. Heavy iron gates magnify every foundation problem. When a post shifts even an inch, you feel it at the latch. Iron gate repair in San Antonio generally runs $190 to $580, with full hinge replacement on a heavy iron swing gate landing between $350 and $700.
Post Settling and Gate Sag
San Antonio’s wet-dry cycles swell and shrink the soil under post footings. An iron gate that scraped fine in May can drag by August. The fix isn’t cranking the hinge tighter; it’s resetting the post and correcting the mount so the panel hangs true under its own weight.
Rust Treatment at Weld Points
Humidity and occasional coastal moisture drift make rust a steady issue at San Antonio weld joints. We grind, treat, and reseal those points before they become structural failures. On a powder-coated iron panel, that patch happens before the rust creeps under the finish.

Trusted Brands We Service in San Antonio
We’re factory-familiar with nine major opener brands, and we carry local parts stock in our San Antonio office for Viking, Ghost Controls, and DoorKing systems, which cover a large share of the residential and light commercial market here. That means a Ghost Controls arm assembly or a Viking control board doesn’t have to ship from Dallas when your gate is down. Our technicians train on these boards the way the manufacturers write them, so a repair call on a DoorKing slide gate in Helotes or a Ghost Controls swing gate in Alamo Heights gets diagnosed right the first time.
Common Gate Repair Problems We See in San Antonio Homes
- Clay soil shifting posts: San Antonio’s expansive clay heaves and settles with every rain-drought cycle, pushing post footings out of line and making swing gates sag or bind.
- Solar system fade-out: Prolonged heat exposure and dust intrusion kill solar gate openers fast here. The panel may still light up, but the battery can’t hold enough charge to move the gate.
- Yard crew damage: Loop detectors and safety photocells get knocked out of alignment by mowers and weed trimmers more often than homeowners realize, which disables UL 325 entrapment protection silently.
- Heat-stressed control boards: A metal operator box in full San Antonio sun bakes the capacitors and relays inside, and a board that overheats daily will fail at the worst moment.

FAQs About Gate Repair in San Antonio
The panel itself usually isn’t bending. The post footing is shifting in San Antonio’s expansive clay soil, and tightening the hinge just pulls the panel harder against a post that keeps moving. The real fix is resetting or reinforcing the post, then re-hanging the gate so it swings true. Call (903) 417-0793 and we’ll check the footing before touching a hinge.
Yes, and it’s the single biggest difference between a gate that lasts five years and one that sags in three. San Antonio’s clay swells when wet and contracts during drought, so post footings here need to go deeper and be set with better drainage than in rockier counties. We size every new post footing for the specific soil we find on your lot.
Automatic gate operators must meet UL 325 entrapment standards, which require at least two independent entrapment protection mechanisms, such as a reversing photocell and an obstruction sensor. If your gate doesn’t reverse when it meets resistance or the beam is misaligned, it needs immediate repair. We test that on every automatic gate service visit.
Yes. Most solar opener failures here come from heat-degraded batteries or dust-blocked panels, not the motor itself. We test the panel output and battery health, then replace only what’s failed. A typical solar repair runs $225 to $480. Call (903) 417-0793 for a free site estimate.
Most residential repairs take 1 to 3 hours on site. Commercial slide gate work can run half a day or longer if we’re replacing a full operator. We’ll give you a realistic time window when you book, and the technician’s live arrival time updates on your phone. The written price is agreed before work starts, and the 365-Day Done Right Promise covers every repair we complete in San Antonio.
If your gate isn’t right, call (903) 417-0793. A live person answers 24/7, the estimate is free, and the price you’re quoted is the price you’ll pay.
