Garage Door Garage Door Sensor Installation Leonardtown, MD

Homeowners across Foxwell Point and the surrounding Leonardtown area call us for garage door sensor installation because we know Leonardtown. The common drivers locally are degraded weatherstripping from UV and moisture, moisture-tripped openers and sensors after storms, rusted track hardware and seized rollers, and mildew and rust on shaded, north-facing doors — and we fix the cause, not just the symptom.

Leonardtown's weather writes the maintenance schedule. With a humid subtropical climate — long, hot, muggy summers, mild winters, heavy thunderstorms, and high year-round humidity, doors here face high year-round humidity that rusts springs, cables, and fasteners, frequent thunderstorms that drive rain into tracks and seals, and storm-season wind that stresses panels and bottom seals — and we stock the parts that stand up to it.

Across St. Mary's County, the garage door problems we see again and again are degraded weatherstripping from UV and moisture, moisture-tripped openers and sensors after storms, rusted track hardware and seized rollers, and mildew and rust on shaded, north-facing doors. If that sounds like your door, there's a good chance we can fix it today.

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.
