Garage Door Garage Door Sensor Installation Sullivan, MO

Booked garage door sensor installation in Sullivan, MO? Expect a tech who actually works Franklin County: fast dispatch, an honest diagnosis, and parts on the truck for rusted track hardware and seized rollers, swollen, sticking wood doors in summer humidity, degraded weatherstripping from UV and moisture, and mildew and rust on shaded, north-facing doors.

If you've owned a garage door through a few Sullivan seasons, you know the pattern: a warm, humid climate of sultry summers, abundant rainfall, and damp conditions that work hard on metal hardware brings damp garages that pit galvanized parts over time, morning condensation that collects on cold metal hardware, and frequent thunderstorms that drive rain into tracks and seals. We size and protect replacements accordingly.

When Sullivan doors quit, it's usually rusted track hardware and seized rollers, swollen, sticking wood doors in summer humidity, degraded weatherstripping from UV and moisture, and mildew and rust on shaded, north-facing doors. Our diagnostic isolates the true cause so the fix actually lasts.

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.
