Styles & brands we work with


Automatic Gate Repair
Automatic Gate Repair is the work of restoring a powered gate to normal operation when it stops opening, starts reversing mid-cycle, grinds instead of glides, or refuses to respond to remote controls and keypads. In San Antonio, the most common triggers we see are failed limit switches, worn drive belts, misaligned photo eyes, and control boards damaged by our summer lightning storms. Calder Gate Repair San Antonio diagnoses the exact failure, shows you the problem in plain language, and gives you a written price before any work starts. Most automatic gate repairs run $175 to $450 before parts, depending on the component and how accessible it is.
Common Failure Points
The limit switch tells the gate when to stop moving. When it fails, the gate slams at the end of travel or stops short of the close. We replace limit switches, drive belts, and damaged receiver modules on the spot, and our trucks carry parts for most major brands.
What Gets Repaired vs. Replaced
Some components can be repaired; others are safer and cheaper to replace outright. A cracked control board gets rebuilt, but a burned transformer or a seized gearbox is usually a replacement. We’ll show you pictures of the damage and let you decide before we proceed.
Electric Gate Motor
Electric Gate Motor failure shows up as a humming sound with no movement, a gate that moves only a few inches, or complete silence when you press the remote. The motor is the workhorse of the entire system, and in San Antonio’s heat, capacitor failures and thermal overloads are common in older units. Calder Gate Repair San Antonio stocks replacement motors and motor components for LiftMaster, FAAC, BFT, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. Most electric gate motor replacements in San Antonio run $400 to $900 including installation, depending on the motor’s horsepower and whether the gate is single or dual swing.
Motor Diagnosis Before Replacement
We test voltage at the motor terminals, load test the capacitor, and check the gear reduction before writing up a replacement. Throwing a new motor at a broken limit switch wastes your money, and we won’t do it. The written estimate shows exactly what failed and what the repair includes.
Heat-Related Failures in San Antonio
San Antonio summers push gate motors into thermal shutdown more often than any other season. If your gate works in the morning but dies by early afternoon, heat soak is usually the culprit. We’ll check ventilation, load, and capacitor condition before recommending a motor replacement.
Gate Access Control
Gate Access Control covers the keypads, intercoms, card readers, telephone entry systems, and smartphone apps that let authorized people through your gate while keeping everyone else out. When a keypad stops accepting codes or an intercom goes silent, you’re locked out of your own property or forced to open the gate manually. Calder Gate Repair San Antonio installs, programs, and repairs access control systems for residential driveways and small commercial properties across San Antonio. Basic keypad repairs run $120 to $250, while full telephone entry or card reader installations range from $600 to $1,800 depending on the system.
Programming and Code Management
Losing a tenant or firing a contractor means changing gate codes immediately. We can reprogram keypads, delete old users, and add new credentials on the same visit. For property managers in San Antonio, we set up schedules for maintenance crews without handing out the master code.
Smart Phone Access Integration
Many San Antonio homeowners now open their gates with their phones instead of a remote or keypad. We install and configure app-based access for modern controller boards, including Ghost Controls and DoorKing systems. You get a digital log of every open and close, which is useful when you want to know exactly who came through.
Commercial Gate Operator
Commercial Gate Operator work covers the heavy-duty motors, gearboxes, and control panels that move gates at apartment complexes, business parks, storage facilities, and gated communities throughout San Antonio. These operators cycle hundreds of times per day, and when one fails, it blocks residents, employees, or deliveries immediately. Calder Gate Repair San Antonio services commercial operators from DoorKing, Viking, Elite, FAAC, and BFT. Commercial operator repairs in San Antonio typically run $395 to $1,500 depending on the operator’s size, with full replacements running $1,800 to $4,500 for slide gate systems.
Preventive Maintenance Contracts
For commercial properties, we offer scheduled maintenance that catches failing components before they cause a lockout. A quarterly visit includes chain tension checks, limit switch calibration, and photo eye alignment, and it costs less than one emergency call at 2 a.m. We’ll set up a maintenance calendar around your property’s traffic patterns.
Emergency Commercial Response
A gate stuck open at a storage facility or apartment complex is a liability. We prioritize commercial calls and can dispatch a technician day or night, because our 24/7 dispatch center is staffed by real people in San Antonio who can book, update, or troubleshoot on the spot. The 365-Day Done Right Promise applies to commercial repairs too.
Brands We Service
Viking operators are common on San Antonio apartment gates, and we’ve replaced enough of their control boards and loop detectors to recognize failure patterns quickly. Their slide gate operators are workhorses, but the capacitors and drive belts wear predictably, and we carry replacements on the truck. DoorKing is another brand we see often on commercial properties, especially their telephone entry systems and card readers, which need firmware updates and antenna checks that many general electricians don’t know to perform.
Elite and Ghost Controls are more common on residential gates in newer San Antonio developments like Scenic Oaks and Cibolo. Elite swing gate operators have a specific limit switch calibration procedure, and Ghost Controls systems integrate with smartphone apps that occasionally need re-pairing after a power outage. Whether your gate uses a Viking, Ghost Controls, DoorKing, Elite, or any other make, Calder Gate Repair San Antonio has a technician who knows it.

- The gate stops halfway, every time. This usually points to a photo eye misalignment or an obstruction sensor failing. It’s not just inconvenient; it’s the safety mechanism that prevents the gate from closing on a car or a person.
- You hear grinding or squealing when the gate moves. That sound is metal on metal, typically a failing gearbox or worn chain. Running the gate in this condition turns a $200 repair into a $1,000 replacement within weeks.
- The remote works sometimes, not others. Intermittent operation often means a failing receiver module or a control board on its way out. It’s also the hardest problem to diagnose without testing equipment, which is why guessing wastes money.
- The gate moves slower than it used to. A slowing gate signals a motor losing torque, a capacitor weakening, or a gearbox breaking down. Catching it early often saves the motor entirely.
- Your keypad or intercom has stopped responding. Access control failures are a security gap, not just a convenience issue. If tenants or family members can’t reliably open the gate, authorized people start propping it open, which defeats the purpose of having a gate at all.
Our Process, Step by Step
- 1
Call and talk to a live person. You call (361) 314-4803 and a real human in our San Antonio dispatch center answers. We ask about the symptoms, schedule a visit, and send you a trackable arrival time. No voicemail, no chatbot, no four-hour window.
- 2
A background-checked technician arrives on time. Your technician shows up in uniform with a stocked vehicle. We test the motor, control board, sensors, and mechanical components using multimeters and load testers to pinpoint the failure before quoting anything.
- 3
You receive a written price before work starts. After diagnosis, we write up exactly what’s wrong, what we’ll fix, and what it costs. You approve the number before we touch a bolt. The invoice you pay at the end matches the number on that paper.
- 4
We repair and photograph the work. We complete the repair, test the gate through multiple open and close cycles, and take before-and-after photos of the repaired components. You see what we did, and you keep the digital record.
- 5
You pay from a digital invoice, and the 365-Day Done Right Promise begins. You pay from a link we send you, and your repair is guaranteed in writing for 365 days. If it fails within that year, we come back at no charge.
How Much Does Electric Gate Repair Cost in San Antonio?
A typical electric gate repair in San Antonio runs $175 to $450 for common fixes like limit switch replacements, remote receiver issues, and keypad programming. Electric gate motor replacements run higher, usually $400 to $900 including installation. Commercial gate operator repairs start around $395 for sensor and chain adjustments and climb to $1,500 or more for control board and gearbox replacements on heavy slide gates. Access control work varies widely: a simple keypad replacement is $120 to $250, while a full telephone entry system installation runs $600 to $1,800.
What affects the price? The gate’s size and type, the brand of the operator, how accessible the motor is, and whether we’re repairing a component or replacing it outright. Slide gates cost more than swing gates because the chain drive and track wear differently. A LiftMaster on a single swing gate is typically cheaper to repair than a commercial Viking slide operator that cycles hundreds of times daily. You avoid overpaying by getting a written diagnosis before agreeing to anything, which is exactly what Calder Gate Repair San Antonio provides on every job. Your free estimate includes the full diagnosis, the written price, and a clear explanation of what caused the failure.
