Why Calder Gate Repair San Antonio Is San Antonio’s Preferred Gate Repair Company
San Antonio’s housing stock runs from 1890s King William mansions with original wrought iron to 2020s Hill Country subdivisions with solar-ready automatic driveway gates. Most gate companies here specialize in one or the other. We handle both, which matters more than you’d think: a tech who only does modern openers won’t recognize a hand-forged barrel hinge, and a welder who restores antique iron won’t know why your Viking control board is throwing error code 4 after a thunderstorm. Our Gate Repair team is factory-familiar with nine opener brands, and we stock parts for legacy DoorKing and FAAC boards that most San Antonio distributors stopped carrying years ago.
We’re part of the Relay Home Co. family, founded in 2009, and Calder Gate Repair San Antonio is independently owned and operated under the Relay Standard: live arrival time you can track, before-and-after photos from the job, and a digital invoice you pay from your phone. Nico Alvarez runs our San Antonio operation and stands behind every job. Background-checked, uniformed techs. Written price before any bolt turns. No phone tag, no four-hour windows, no invoice surprises.
Styles & brands we work with


Sliding Gate Repair in San Antonio
Sliding gate repair in San Antonio runs $220 – $480 for the most common failures: rollers that have flattened or seized, tracks that have shifted out of level, chain or belt tension loss, and limit switch failures that leave the gate stopping mid-travel. Sliding gates are everywhere in San Antonio’s newer subdivisions around Alamo Ranch, Cibolo, and the outer Loop 1604 corridor, where long driveways and HOA requirements make them the default choice. When they fail, they usually fail after weather events or years of accumulated debris in the track.
Track and roller rebuilds
San Antonio’s limestone soil dust and caliche runoff get into sliding gate tracks faster than most homeowners expect. We pull the gate off the rail, measure the wear pattern on the rollers, and replace or machine new ones as needed. If the track itself is bowed from a shifting post, we reset the post properly rather than shimming it, because shims fail within a season or two on this soil.
Opener and limit switch failures
Older LiftMaster and DoorKing slide openers from the mid-2000s are still running all over San Antonio, but their limit switches, the small sensors that tell the gate when to stop, wear out and produce that “opens halfway then reverses” behavior after rain. A limit switch rebuild costs $150 – $260 on its own. If the control board is original, we’ll tell you honestly whether a repair makes sense or whether a new operator is the cheaper five-year answer.
Wrought Iron Gate Repair in San Antonio
Wrought iron gate repair in San Antonio typically runs $280 – $650 depending on whether we’re rebuilding a hinge post, machining a replacement latch, or cutting and welding rusted bottom rails. In older districts like Monte Vista, Alta Vista, and King William, many gates are original to the home, and the ironwork details, scrolls, latch plates, hand-forged hinges, are not something you’ll find at a supply house. We replicate them.
Post footings and hinge rebuilds
San Antonio sits at the edge of the Edwards Plateau, and in hillside neighborhoods the original posts were often set directly into limestone or thin, rocky soil with un-reinforced concrete. We see more post-footing failures per lane-mile here than in flat, clay-heavy Houston. When a post leans, the top hinge shears and the gate drags. We pull the post, pour a new footing with rebar pinned into the limestone, and machine replacement hinges to match the surviving hardware.
Rust repair and latch restoration
Humid summers and irrigation overspray cause rust at the bottom rail and decorative scrolls on San Antonio iron gates. Left alone, that rust welds the latch mechanism shut until the gate can’t be opened without cutting it. We cut out the rot, weld in matching stock, and rebuild or replace the latch while preserving the original pickets. We rebuilt a sagging swing gate on a King William home where the original 1890s hinge post had rotted below grade. Our techs pulled the post, poured a new footing pinned into the limestone, then machined a replacement barrel hinge to match the surviving leaf. The gate swings true now, and the client kept every original picket.
Trusted Brands We Service in San Antonio
We’re factory-familiar with nine gate opener brands, and around San Antonio we see a lot of Viking, Ghost Controls, and DoorKing units in particular. That familiarity translates to faster diagnosis and parts we actually carry on the truck. Older DoorKing and FAAC control boards from the early 2000s fail after San Antonio thunderstorms, and replacement boards for those legacy models are often no longer stocked by local distributors. We keep common boards, remotes, photo-eyes, and limit switch kits on hand in our San Antonio operation so we’re not waiting on a shipment to finish your repair. If you’ve got an Elite or Mighty Mule unit, we handle those too, but the legacy Viking and DoorKing calls are the ones we know best.
Common Gate Repair Problems We See in San Antonio Homes
- Thunderstorm-fried control boards. San Antonio’s spring and fall storm season sends power surges through gate openers, and 15-to-20-year-old DoorKing and FAAC boards don’t always survive. The gate freezes mid-travel and your remotes unpair themselves.
- Leaning hinge posts in hillside neighborhoods. In Monte Vista and Alta Vista, original posts were set in un-reinforced concrete or directly into limestone. The post shifts, the top hinge shears, and the gate drags on the driveway.
- Rust at the bottom rail and decorative scrolls. Irrigation overspray plus humid summers equals rust on the bottom rail and scrolls of iron gates. It starts cosmetic and ends with a latch that won’t move without cutting.
- Obsolete safety systems that don’t work anymore. Many San Antonio gates were installed before photo-eye and safety edge requirements. The opener still runs, but the safety devices are dead, and in some cases the gate reverses unpredictably.

FAQs About Gate Repair in San Antonio
In most cases it’s neither. The most common cause we see on mid-2000s LiftMaster slide gates in San Antonio is a worn limit switch, the small sensor that tells the gate when to stop. Rain and humidity accelerate the failure, which is why it happens after storms. Before assuming a dead operator, we test the limit switch and the loop detector, because the loop detector is a separate failure that looks similar. A limit switch rebuild runs $150 – $260. A loop detector replacement runs about the same. We’d test both before selling you a new operator. Call (361) 314-4803 and we’ll be honest about which one it is.
Almost always, yes. We rebuild hinges, reset posts, machine replacement latch plates, and weld matching stock into rusted rails without pulling the original ironwork. The only times we’d recommend replacement are when the post itself is too far gone and the gate’s structural rails are rusted through in multiple places. Even then, we can often save the original pickets and scrolls and re-hang them on new rails. In King William, preserving original ironwork matters, and we’ve rebuilt 1890s gates that are still swinging true.
Yes, you do. Modern safety standards require photo-eyes and safety edges on automated gates, and if your FAAC swing gate doesn’t have working ones, it’s both a liability and a code issue if you ever sell the home. More importantly, a FAAC swing gate without functioning photo-eyes can close on a child, a pet, or a car. We can retrofit photo-eyes and safety edges onto older FAAC systems without replacing the entire operator, and the cost is typically $300 – $550. It’s not a cosmetic upgrade; it’s the single most important safety item on your gate.
You can weld a brace on, but it won’t fix the underlying problem. A gate that sags in the middle on a San Antonio property usually means the hinge post has shifted or the hinge itself is worn, not that the panel is weak. In limestone soil, posts shift over time, and welding a brace onto the gate just masks the lean for a few months before the top hinge shears. We’d rather reset or reinforce the post and rebuild the hinge, which is the actual fix. The brace is a Band-Aid. Call (361) 314-4803 and we’ll tell you which one your gate actually needs.
Yes, and solar openers are actually one of the cleanest retrofits for historic district gates where trenching conduit across a limestone yard is either prohibited by the HOA or just wildly expensive. We install solar-compatible operators from Viking, Ghost Controls, and Elite on existing wrought iron gates, and the panel generally mounts on the gate or a nearby post without altering the historic ironwork. The catch is that solar openers need a clear line of sight to the afternoon sun, so heavily shaded Monte Vista lots may need a remote panel placement. We’ll assess that on a free estimate.
