What Our Sensor Service Includes
The safety sensors sit low on either side of your garage door track, watching for anything in the door's path before it closes. Over time, dirt on the lens, a bumped bracket, worn wiring, or plain age can throw them out of sync. Our technicians restore that function by realigning the units, clearing or swapping out damaged lenses, and replacing sensors that are beyond saving.
If your door stops short of the floor, bounces back up mid-close, or your opener's indicator light won't stop blinking, the sensors — not the motor — are almost always the culprit.
Why Working Sensors Matter
These small units are your door's last line of defense against a serious accident. A sensor that can't see an obstruction may let the door close on a child, a pet, a bike, or a parked car.
It's also worth noting: a lot of "the opener quit working" service calls turn out to be a sensor fault, not a motor failure, once we actually get eyes on the unit.
How We Handle a Sensor Call
Check Sensor Alignment
We verify both units are pointed correctly at each other — a fraction of an inch off is often enough to keep the door from closing.
Clear or Swap the Lenses
Grime, moisture, or cracked housings are addressed so the sensors can reliably spot what's in the door's path.
Trace the Wiring
We follow the wiring back to the opener, looking for frayed, pinched, or loose connections that cause on-again, off-again faults.
Run a Live Safety Check
Before we leave, we test the reverse-safety response ourselves to confirm the door actually stops and backs off when it should.

Sensor Repair & Replacement FAQ
That's the classic sign of a sensor problem — usually a slightly off alignment, a dirty lens, or something sitting in the sensor's line of sight.
Most opener units flash their light to flag a sensor error. It's typically a misalignment or a wiring fault, not the motor, and it's worth having checked.
Small adjustments are sometimes doable on your own, but if the problem keeps coming back, it's often a wiring or lens issue that's tricky to pin down without the right tools. We're glad to take a look.
Yes. A sensor that isn't detecting properly can let the door close on someone or something underneath it, so this isn't something to put off.
Most calls are done inside an hour — that covers diagnosis, the realignment or replacement, and a final safety test.
It is. Our sensor work comes with a workmanship guarantee, and we'll go over the details with you at the time of service.
