ABOUT US

Why Garage Door Sensors Matter in St. Albert

Garage door sensors are small but mighty. They sit on each side of your garage door opening and create an invisible beam. If anything blocks that beam, the door stops and reverses—that's the safety feature that protects kids, pets, and cars. St. Albert's weather can be tough on sensors. Winter frost, spring thaw, and summer dust all affect how well sensors work. When sensors get misaligned or dirty, your door won't close properly. That's a security risk and a hassle. StAlbertGaragedoors.ca specializes in fixing sensor problems for St. Albert residents and businesses. We clean sensors, realign them, check wiring, and test the beam to make sure everything works. A working sensor is a safe garage door.

How We Repair Your Garage Door Sensors

1

Inspect Both Sensors

We check the sensors on both sides of your door opening. We look for dirt, frost buildup, or physical damage. In St. Albert's climate, we pay special attention to winter frost and dust accumulation.

2

Test the Beam

We use a diagnostic tool to test if the infrared beam is working. A broken beam means the sensors can't talk to each other.

3

Clean or Realign

Dirty sensors just need cleaning. Misaligned sensors need adjustment. We do whichever your door needs.

4

Check the Wiring

Loose or damaged wires stop sensors from working. We inspect the wire connections and fix any problems.

5

Test the Door

We test your garage door multiple times to confirm it closes smoothly and reverses when it should. Safety is the priority.
