Electric gate repair in Selma usually means one of three things: the opener motor quit, the gate won’t move despite power at the panel, or the safety sensors keep tripping and reversing the gate. Calder Gate Repair San Antonio fixes all of it, and we’re the team Selma homeowners call when a builder-grade operator finally gives out or a freeze knocks the board offline. We work throughout Selma, from Olympia Hills to Retama Springs to the original Selma townsite, and our dispatchers can usually get a technician to your driveway the same day you call. If the gate is stuck open, stuck shut, or grinding and stopping halfway, call (361) 314-4803 and a live person will pick up.
Why Calder Gate Repair San Antonio Is Selma’s Preferred Electric Gate Repair Company
Selma has grown fast – really fast. What was a small stop along I-35 twenty years ago is now a dense patchwork of subdivisions and master-planned communities, and those neighborhoods came with a lot of gates. Many were installed with the cheapest operator the builder could source, and they’re all hitting their failure window at roughly the same time. We know exactly which boards, gears, and sensors those 2000s-era systems used, because we replace them every week. Calder Gate Repair is the dedicated gate repair specialist inside the Relay Home Co. family, and our Selma customers get the same three written guarantees every homeowner gets: a written price before any work starts, a written guarantee on the repair, and a free second visit if that repair fails within the 365-Day Done Right Promise window.
Nico Alvarez leads our gate team, and he’s trained on nine major opener brands – LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. That breadth matters in Selma because the neighborhoods are so varied. A gate in the original Selma townsite needs different treatment than one in a 2015 build east of I-35. Our technicians are background-checked, uniformed, and dispatched with a live arrival time you can track on your phone. No four-hour windows, no voicemail tag. The Relay Standard is a live arrival time, before-and-after photos of the work, and a digital invoice you pay from a link.
Styles & brands we work with


Commercial Gate Operator in Selma
Commercial gate operators in Selma serve a different role than the residential units we see in most subdivisions – they’re designed for higher cycle counts, longer run times, and often need to integrate with access control systems, keypads, and vehicle detection loops. When a commercial operator at an HOA entrance or business off Loop 1604 fails, it’s rarely just the motor. We trace the full loop: power supply, junction boxes, the run from the controller to the operator arm, and the safety edges.
Operator Arm and Drive Replacement
Commercial swing arms and slide operators take abuse daily. A seized gearbox or a failed hydraulic pump under an HOA gate on Evans Road is a full function loss, not a convenience issue – residents and delivery trucks stack up. We replace the operator and match the new unit’s cycle rating to the actual traffic, not the builder’s original spec.
Expect commercial operator work in Selma to start around $750 for a basic slide operator replacement and climb quickly when underground loops or keypads need work.
Access Control and Loop Integration
If the gate opens for the callbox but not for the vehicle loop, the operator often gets blamed when the loop is the problem. We test the detector and the field wiring before replacing any operator. On commercial Selma gates we also verify the close timer, the reversing edge, and the photo eye alignment so the operator isn’t fighting a bad input.
Automatic Gate Repair in Selma
Automatic gate repair in Selma covers the full residential setup: the gate operator, the control board, the remote control, the keypad, and the safety sensors or photocells. When a Selma homeowner says their gate “acts weird” – opens halfway, beeps but doesn’t move, closes and then reverses for no reason – we start at the operator and work outward. Most residential automatic gate repairs in Selma run between $180 and $340 before parts, depending on what the diagnostic turns up.
Safety Photocells and Reverse Edges
Photocells get dirty, misaligned, or sun-beaten. A gate that refuses to close is usually a photo eye issue, and the fix is often a cleaning, realignment, or replacement of a $40 – $80 sensor pair. But the test has to be thorough – a bypassed photo eye is a liability, and we won’t leave a residential gate running without a functioning reversing edge, especially with kids and pets in the neighborhood.
Safety matters on automatic gates because they move hundreds of pounds without someone holding the controls. Gate sensors and reverse edges are a genuine injury risk when they’re miswired, so we test them under load rather than just checking continuity.
Freeze Damage and Cold Snaps
Selma doesn’t freeze often, but when it does, the damage spreads fast. Plastic gear teeth shear, capacitors pop, and boards that were already running hot fail on the next power-up. If the gate worked before the freeze and went dead after, a thermal contraction crack in a plastic gear or a swollen capacitor is the usual culprit. Repairs start with component-level diagnosis, not a full board replacement quote.
Trusted Brands We Service in Selma
We’re factory-familiar with the major names in Selma’s gate landscape: DoorKing, Elite, Mighty Mule, LiftMaster, and others. Many Selma homes have Mighty Mule units from the big-box era, and those parts are cheap but plentiful – we stock the common boards and arm assemblies so we’re not ordering and waiting. LiftMaster and DoorKing show up on the newer builds. If your gate is a brand we don’t stock locally, we still repair it. Parts come fast from two regional suppliers.
Common Electric Gate Repair Problems We See in Selma Homes
- Builder-grade operator failures in 2000s master-planned communities. These units fail after 10 – 15 years almost on schedule. The gearbox seizes or the control board burns out, and the original brand usually isn’t worth rebuilding.
- Undersized low-voltage wiring from house to gate. We open junction boxes in Selma and find 20-gauge or even 22-gauge wire that was never meant for a modern opener’s amp draw. The fix is often a new 18-gauge two-conductor run in PVC conduit.
- Solar opener batteries dying after Selma’s hot summers. North-facing solar panels in newer subdivisions collect less sun than the spec sheet assumes, and after repeated 95°F days the battery can’t hold a charge. Two cloudy days later, the gate is dead.
- Rust at the base of steel gate posts in older Selma sections. In the original Selma townsite near Cibolo Creek, soil moisture and occasional flooding accelerate corrosion. Posts that look fine at eye level can be paper-thin at grade level.

FAQs About Electric Gate Repair in Selma
Usually the failure is mechanical rather than electrical. The plastic gears inside a builder-grade operator contract in freezing temperatures and crack under load. The motor then spins but the gate doesn’t move, or the gate moves a few inches and stops. In some cases a capacitor on the control board pops on the next power-up. We see this most often in Selma’s 1990s and 2000s housing stock where original operators are still running. The repair can be as fast as a gear replacement, or it may make more sense to upgrade the operator while it’s open. Call (361) 314-4803 before a sunny day warms everything up and the symptom fades.
Yes, and this is one of the most common upgrades in Selma. Many homes in subdivisions built between 1990 and 2010 have ornamental steel gates that were never wired for automation. The gate itself is fine, but adding a LiftMaster or FAAC operator means trenching a new low-voltage run from the house or placing a solar kit with a dedicated post. We usually install new conduit rather than trying to re-use wiring that isn’t there. The full job runs $1,800 to $3,200 depending on gate weight, swing clearance, and keyboard or phone-control preferences.
Photocells work in pairs – one sends an invisible beam, one receives it. If the beam is interrupted while the gate is closing, the gate should stop and reverse. You can test this by blocking the beam with your hand while the gate is closing. If the gate keeps closing, the sensors are misaligned, dirty, or bypassed. A bypassed photo eye is dangerous and should be corrected immediately. Our techs test every photo eye and reverse edge during a gate repair in Selma because it’s a genuine safety matter, not a checkbox.
It does, especially in the original Selma townsite and low-lying areas near Cibolo Creek where the soil holds moisture. Steel posts rust at grade level, and shifting clay soil under newer subdivisions can also cause posts to lean slightly, which misaligns the gate and strains the operator. We check post integrity during every repair, because a new operator bolted to a failing post is a future warranty call and a future hazard. Sometimes we recommend a post replacement or concrete collar before we touch the operator.
Yes, and we do this constantly in Selma. Most builder-grade openers can accept a third-party receiver or a control board upgrade that gives you phone-based control and a wireless keypad. The key is whether the existing low-voltage wiring is heavy enough for the new amp draw; in older Selma homes it often isn’t. We’ll quote the upgrade with and without a new wire run so you know the full cost before we start. Most upgrades run $350 to $650 for the controller and receiver, plus keypad and wire work as needed.
