Garage Door Garage Door Sensor Installation South San Francisco, CA
Garage door sensor installation in South San Francisco, CA is routine work for us. Local failure modes — drifting travel limits on aging chain-drive openers, frayed lift cables on aging sectional doors, sun-faded, brittle weather seals along the bottom panel, and corroded low brackets on homes near the coast — are exactly what our trucks are stocked for.
In California's Mediterranean climate region, a mild Mediterranean climate of warm, dry summers and gentle, damp winters, with low annual rainfall and abundant sun. For South San Francisco garages that translates into long dry spells that crack aging weatherstripping, dry-season dust that works into open tracks, and mild but steady humidity swings that quietly seize hinges, so our tune-ups focus on the components that wear first under these conditions.
Across Sunshine Gardens, Westborough and Sign Hill, what brings South San Francisco homeowners to us is drifting travel limits on aging chain-drive openers, frayed lift cables on aging sectional doors, sun-faded, brittle weather seals along the bottom panel, and corroded low brackets on homes near the coast — and we resolve it without a second visit.
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.
Photo-eye electronics fail at 10–15 years. Replacement is inexpensive and quick.
