Garage Door Garage Door Sensor Installation Lexington, TN

In Lexington, every garage door sensor installation starts with the local picture — a humid subtropical climate — long, hot, muggy summers, mild winters, heavy thunderstorms, and high year-round humidity. We choose hardware that survives Tennessee's humid subtropical region, not whatever's cheapest on the shelf.

Because Lexington has a humid subtropical climate — long, hot, muggy summers, mild winters, heavy thunderstorms, and high year-round humidity, the doors here age differently than inland or coastal homes elsewhere. The usual culprits are summer heat and moisture that swell wood doors and seize rollers, damp garages that pit galvanized parts over time, and morning condensation that collects on cold metal hardware — exactly what our techs come prepared for.

We've fixed thousands of doors around Henderson County, and the pattern holds in Lexington: swollen, sticking wood doors in summer humidity, rusted bottom brackets on damp slabs, storm-driven debris and water in the tracks, and corroded springs and cables in the humid air. None of it should leave you without a working garage for more than a day.

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.
