Garage Door Cable Repair in Dunnville
Cable and drum repairs by Leo, owner and technician at LTA — fast, safe, and done right throughout Dunnville.
Safety warning: Garage door cables work under extreme tension with the springs. Do not adjust or replace them yourself — call a professional to avoid serious injury.
What is this cable drum?
Leo explains how the cable, drum, and torsion shaft work together to lift the door. When the shaft turns, the drum winds the steel lift cable into its grooves and raises the door evenly on both sides.
If a cable slips out of those grooves, frays, or loses tension after a spring failure, the door can sit crooked, jam partway open, or drop unevenly — all signs to stop using the door and call for repair.
