Garage door opener repair is the diagnosis and fix (or replacement) of the motorized unit that powers door operation. Common failures include burnt-out motor windings, dead capacitors, broken drive gears, failed safety sensors, and worn chain or belt drives.
Symptoms: motor hums but door does not move, opener runs but door reverses immediately, remote works but wall button does not (or vice versa), grinding noise during operation, slow or jerky travel.
We diagnose first, fix when possible — gear replacement, capacitor swap, sensor calibration, board replacement. Full opener replacements include LiftMaster, Chamberlain, Genie, and Liftmaster Elite Series with Wi-Fi smart features. Belt-drive recommended for noise-sensitive installations.

Real reviews from Sarnia homeowners — part of our 4.9-star average across 63 reviews.
Door would reverse halfway every time. Tech adjusted the safety sensors and force settings — turned out the sensors were just misaligned. Small fix, fair charge.
Opener was making a grinding noise for weeks. They caught it before it failed completely. Replaced the gear and sprocket, runs silent now.
Opener motor was humming but the door wasn't moving. Turned out to be a stripped gear. Fixed it instead of pushing a full replacement — appreciated that.
