Photos of finished work are useful, but the before is where the story lives. Every repair we do in San Antonio starts with a gate that won’t close, won’t open, or makes a sound like a car accident waiting to happen. The after matters because it’s your family, your driveway, your routine back to normal. Here are a few recent transformations from neighborhoods around San Antonio.
Styles & brands we work with


Recent Transformations
Slide Gate Off Track in Alamo Heights
Before
AfterThe gate had jumped the rail after a San Antonio storm washed gravel into the track. The owner had been forcing it closed by shoving it, which bent two of the guide wheels. We pulled the gate back, cleared the stones, replaced the bent wheels, and set the rail level. Now it glides with a two-finger push instead of a shoulder.
LiftMaster Keypad and Safety Sensor Swap in Stone Oak
Before
AfterThe keypad had been dead for months, so the family was cycling the gate from inside the house. The safety sensors, the little eyes near the ground that stop the gate if a child or pet crosses, were also misaligned. We installed a new LiftMaster keypad, realigned both sensors, and tested it with a football rolled under the gate. Works as it should.
Mighty Mule Opener Making a Grinding Noise in Helotes
Before
AfterYou could hear this Mighty Mule from the street. The internal drive gear had worn down to smooth teeth, so the motor spun but the arm barely moved. We opened the unit, cleaned out the metal dust, and replaced the gear set. The gate opens at normal speed and the only sound now is the chain clicking into place.
FAAC Hydraulic Ram Leaking in Terrell Hills

This one left a small black puddle at the base of the gate every morning. The ram seal had failed, and once the fluid level dropped, the gate would stop halfway and stall. We replaced the ram assembly and refilled the system with the correct FAAC hydraulic fluid. After cycling it twenty times, the gate closed completely and held with no new drips.
Viking Control Board Burned Out After Outage in Castle Hills

A power surge during a July storm took out the Viking board. The gate would not respond to remotes or the wall button. We removed the fried board, confirmed the transformer still fed power, and installed a new Viking board programmed to the existing remotes. The owner did not need to reprogram a single remote in the car.
BFT Swing Gate Hinge Sag Freeport-Style Wall in Shavano Park

The gate leaf had been grinding against the driveway for weeks because the lower hinge was worn oval. That drag was also overloading the BFT motor. We lifted the leaf, replaced both hinges, and remounted the motor arm so it pulled in a straight line. The gate swings silent and clears the pavers by a good inch and a half.
