Our technicians know this city’s gate problems because they see them every week. A control board that cooked in the August heat on a west-facing driveway near Lackland Air Force Base. A chain-drive opener that seized up after a thunderstorm flooded the track in Alamo Heights. These aren’t hypotheticals. They’re the calls we run.

Styles & brands we work with


Gate Servicing in San Antonio
Gate servicing in San Antonio means something different here than it does in other climates, because our heat and humidity punish gate hardware year-round. A service visit typically includes inspecting and lubricating hinges, checking the operator’s force settings, cleaning the track, testing safety photocells, and tightening hardware that San Antonio’s temperature swings have loosened. Most standard servicing visits in San Antonio run $150 to $250, though adding component replacement pushes that higher.
Seasonal Wear Checks
San Antonio’s intense UV exposure degrades plastic gears, wire insulation, and photocell lenses faster than homeowners expect. A servicing visit catches these before the gate fails on a 102-degree afternoon. We recommend an annual check for gates with heavy daily use, and twice-yearly checks for wrought iron gates exposed to full sun.
Bearing and Hinge Maintenance
Older gates, especially in neighborhoods like Monte Vista and Olmos Park, tend to sag as hinge bearings wear. Once a gate sags, the operator strains harder, which shortens its life. Our servicing catches that early. Replacing worn bearings and adjusting the gate’s center of gravity often restores smooth operation without touching the opener itself.
Gate Intercom in San Antonio
Gate intercom in San Antonio gets complicated when older systems fail, because many homes in established neighborhoods have hardwired intercom lines that predate wireless options. The heat accelerates capacitor failure in older intercom power supplies. A typical intercom repair or component replacement runs $160 to $310 in San Antonio, depending on whether we’re replacing a handset, a power supply, or the call button at the gate.
Upgrading Legacy Intercoms
Many San Antonio homeowners discover their gate intercom still works when the gate opens fine, but the units inside the house have failed. In those cases, we often retrofit a wireless intercom or integrate the gate into a phone app, so you never need a hardwired handset again. That usually runs $250 to $450, installed.
Keypad and Reader Repairs
Outdoor keypads on San Antonio gates take brutal sun exposure. The membrane switches crack and let in humidity, which corrodes the contacts. If your keypad works sometimes but not others, especially after rain, that’s the likely culprit. Replacement keypads for LiftMaster, Mighty Mule, and DoorKing operators typically run $90 to $180 plus installation.
Trusted Brands We Service in San Antonio
Calder Gate Repair San Antonio is factory-familiar with DoorKing, Elite, Mighty Mule, LiftMaster, and five more major brands. That matters when a 20-year-old LiftMaster control board fails and the manufacturer has discontinued it. We know which aftermarket boards work, which rebuilt units we trust, and when retrofitting a newer operator is the cheaper long-term answer. Our San Antonio crews carry common control boards, photocells, and remotes for these brands, which means many repairs don’t wait on a parts shipment. If we don’t have it on the truck, we’ll give you an honest arrival date before you commit.

AfterCommon Gate Opener Repair Problems We See in San Antonio Homes
- Heat-damaged control boards: San Antonio summers push control boards past their thermal limits, especially when the operator housing sits in direct afternoon sun. Symptoms include the gate not responding to remotes, opening but not closing, or erratic behavior that gets worse on hot days.
- Rusted hinge posts on older wrought iron gates: In historic districts like King William and Monte Vista, decades of humidity have corroded the hinge posts inside masonry pillars. The gate sags, the opener strains, and eventually the operator burns out. We rebuild the post footing and re-hang the gate square.
- Photocell failures from thunderstorm glare: San Antonio’s late-afternoon thunderstorms create sudden light changes that confuse older photocell sensors. If your gate reverses for no reason or won’t close when it’s cloudy, the photocells likely need realignment or replacement.
- Missing entrapment protection on pre-2000 operators: Many slide gates on mid-century ranch homes and 1990s subdivisions lack modern safety photocells. These gates don’t meet current UL 325 requirements and can be genuinely dangerous. We retrofit safety edges and photocells so the gate stops and reverses if anything is in its path.
Pricing for Gate Opener Repair in San Antonio, TX

FAQs About Gate Opener Repair in San Antonio
In most cases we can repair the original latch, even when it’s a hand-forged mechanism no modern supplier stocks. San Antonio’s humid summers cause these old latches to seize, and the fix often involves disassembly, rust removal, and custom fabrication of the worn internal components. If the latch body has cracked or the internal spring has failed beyond repair, we’ll explain why replacement is the better option and give you a written price either way. Call (361) 314-4803 for an on-site assessment.
That’s almost always a failed limit switch or a misaligned force setting, and both are straightforward repairs. The limit switch is the small sensor that tells the gate when to stop. San Antonio’s heat degrades these switches faster than in cooler climates. We test the switch, recalibrate the force settings, and check the safety photocells. Most reversing issues we fix for $190 to $290. Call (361) 314-4803 if your gate won’t stay closed.
The fix starts with the hinge post, not the opener. On mid-century ranch gates, the post has usually rotted at the base or shifted in the soil. We set a new steel post footing, re-hang the gate square, and then assess whether the opener is still worth keeping. If the sag damaged the operator’s gearbox, we’ll show you the wear and give you a written price for repair or replacement before doing anything. Sag repairs on Oak Hills-style gates typically run $280 to $520.
If your gate predates 2000 and has never been retrofitted, it probably does not meet current UL 325 entrapment protection standards. That’s true across San Antonio, and it means the gate might not stop if a child or pet is in its path. We retrofit safety photocells and contact edges so the gate reverses on obstruction. It’s a safety upgrade, not an upsell. Most retrofits run $280 to $480 per gate leaf. Call (361) 314-4803 for an evaluation.
Yes, and that’s a smart move for properties where running a power line is impractical. San Antonio’s sunshine makes solar a reliable power source for gate operators most of the year. We install solar panels, battery banks, and compatible operators, typically for $750 to $1,200. We’ll also confirm the panel placement gets enough direct sun, because oak trees on north-side properties can shade the panel more than owners realize. Call (361) 314-4803 for a free site assessment.
