- 24/7/365 Garage Door Services
If your garage door won’t close or keeps reversing for no reason, there’s a good chance your safety sensors are out of alignment or malfunctioning. These small devices, located near the bottom of your garage door tracks, play a crucial role in keeping your door safe.
At Calgary Garage Door Fix, we specialize in fast, affordable garage door sensor repair and replacement services across Calgary — from Tuscany and Evanston to Mahogany, Silverado, and McKenzie Towne. Wherever you are in Calgary, we’ll get the job done within a few hours of your call.
Garage door sensors (also known as photo eyes) prevent your door from closing on people, pets, or objects. They work by sending an invisible infrared beam between two sensors mounted on either side of your door.
If that beam is interrupted — or if the sensors are dirty or misaligned — the door will automatically stop or reverse for safety.
The garage door won’t close, even though nothing is blocking it.
The door closes partway, then goes back up.
The opener lights flash repeatedly.
One or both sensor lights are off or blinking.
The door works fine in the evening, but not during the day (sunlight interference)
If you’re experiencing any of these issues, our technicians can quickly diagnose whether your sensors just need an adjustment or full replacement.
We believe in straightforward, upfront pricing—no surprises, no upselling.
Sensor adjustment or realignment: $120 + GST
(includes cleaning, alignment, and system testing)
Sensor replacement: $160 + TAX
(includes new sensors, installation, and calibration)
Both services include a full safety inspection to ensure your entire garage door system is working properly.
