Steel lift cable attached to a bottom bracket on a garage door

Garage Door Cable Replacement

Replacement of frayed, slipped, or snapped lift cables before they damage the door.

About Garage Door Cable Replacement

Lift cables carry the door's weight alongside the springs. When a cable frays or slips off its drum, the door can hang crooked or fall. Garage door cable replacement restores even lifting. This page covers the warning signs and how replacement is generally done.

How Cables Wear Out

Cables run from the bottom brackets up to the drums, flexing every time the door cycles. Moisture, road salt carried in on vehicles, and friction slowly break strands. A single broken strand is a warning, not a cosmetic flaw, since the rest of the cable carries more load each cycle.

What to Look For

Fraying or broken strands near the bracket
A cable that hangs loose or off the drum
A door tilting to one side
Slack in the cable when the door is closed
Rust or discoloration along the cable

What Cable Replacement Includes

Replacement includes releasing tension safely, removing the old cable from the bottom bracket and drum, installing a new cable of the right length, and verifying that the door lifts evenly. Because cables connect to spring tension, this work is closely linked to spring safety and often shows up together with bracket or drum inspection.

How the Process Generally Works

1
Secure the door
The door is held in position and spring tension is controlled before any cable is touched.
2
Remove worn parts
The old cable and any damaged bottom bracket are taken out.
3
Install and route
A new cable is seated on the drum and attached to the bracket on each side.
4
Level and test
Both sides are matched so the door rises evenly and rests flat.

Why Cables Usually Go in Pairs

Both sides carry equal load and wear at a similar rate. Replacing one side only can leave a worn partner that fails soon after. Inspecting both is a reasonable habit even when only one has visibly failed.

What Homeowners Can Do

Look at the lower corners of the door twice a year. Keep hands, tools, and stored items clear of the brackets. Never grab a cable or bracket to lift a stuck door, because the bracket is under high tension.
