Garage Door Cable Repair in London, ON: Safe Solutions

Why garage door cables fail

The lift cables run from the bottom corners of the door up to the spring drums, carrying the door’s weight alongside the springs. They fail three ways: slow rust and fraying (often from a damp or road-salt environment), wear where the cable wraps the drum, and sudden shock when a spring breaks and dumps the full load onto the cables and opener.

You’ll often spot a problem before a full break: a door that hangs slightly crooked, a cable gone slack or unwound from its drum, or visible rust and broken strands.

Why it isn’t a DIY fix

Cables sit under the same extreme tension as the torsion springs. Loosening a drum or unhooking a cable without controlling that tension can release it violently. This is one of the most common sources of serious injury in garage door work, which is why a frayed or snapped cable should be left to a technician with the right winding tools and clamps.

How the repair is done

A technician secures the door, releases and controls the spring tension, replaces both cables (they wear together), re-seats them on the drums, and re-balances the door so it sits level and the opener isn’t fighting it. Because a snapped cable is often a symptom of a tired spring, the springs and rollers get a quick check at the same time.

What cable repair costs in London

Cable and track repair starts at $179, parts and labour included, with a 1-year warranty — the exact price depends on whether tracks are bent and whether the springs also need attention. We carry cable on every truck, so most repairs are same-day, with an up-front price confirmed before any work.
