Garage Door Garage Door Sensor Installation South Alamo, TX

Local matters for garage door sensor installation. In South Alamo and neighboring Alamo, Donna, San Juan, and Scissors, the failures we address most are moisture-tripped openers and sensors after storms, pitted galvanized hardware on older doors, corroded springs and cables in the humid air, and mildew and rust on shaded, north-facing doors, all backed by our 10-year workmanship guarantee.

We spec every South Alamo job for the environment it lives in. Given a warm, humid climate of sultry summers, abundant rainfall, and damp conditions that work hard on metal hardware, the failure modes we plan around are summer heat and moisture that swell wood doors and seize rollers, storm-season wind that stresses panels and bottom seals, and intense UV that degrades rubber weatherstripping — and we carry the corrosion-resistant parts to match.

The calls we get most in South Alamo are moisture-tripped openers and sensors after storms, pitted galvanized hardware on older doors, corroded springs and cables in the humid air, and mildew and rust on shaded, north-facing doors. Each is something our trucks are stocked to fix on the first visit — no waiting on parts.

Photo-eye safety sensors are required by UL-325 on every garage door opener manufactured since 1993. They detect obstructions in the door's path and either reverse the door (during close) or refuse to start (when activated). When sensors are misaligned, dirty, sun-blinded, or failed, the door either refuses to close at all or — worse — closes without sensing an obstruction. Our sensor installation service replaces failed sensors, realigns drifted brackets, cleans the eye optics, and verifies auto-reverse on a real obstruction test.

Replacement eyes are brand-specific (LiftMaster has a different connector and signal pattern than Genie). We stock the major brands and most legacy models. Brackets occasionally need replacement when corrosion has degraded them or impact has bent them. Bracket alignment is critical — eyes that are slightly off-aim trigger intermittent close failures that drive homeowners crazy.

Every visit ends with an obstruction test: a 1.5-inch (3.8 cm) tall object placed under the door at three positions across the opening. The door must reverse when it touches the object. This is the UL-325 baseline — if the door doesn't pass, the install isn't complete. We document the test results on the work order.
