Customer Problem
The homeowner arrived home to find their roller door sitting lopsided — one side an inch or two higher than the other, and refusing to close fully. On a roller door that almost always means a lift cable has jumped its drum: with the cable slack on one side the curtain lifts unevenly, binds in the guides and stops. It's common on newer estates like Byford where doors are large, used constantly and rarely serviced.
- Curtain sitting crooked, higher on one side
- Door binding in the guides and stopping short
- Lift cable found off its drum on the raised side
Inspection & Diagnosis
We inspected the cable for fraying and the drum for damage before touching anything — a cable that jumps because it's frayed needs replacing, not re-seating. This one was sound: it had simply gone slack (usually from the door being stopped on an obstruction or bounced on the way down) and walked off the drum. The curtain, guides and opener were undamaged.
- Cable intact — no fraying or crushed strands
- Drum and guides undamaged
- Curtain edges checked for bends — none
- Cause: cable slack on one side, not a worn part
Solution
With the door supported we unwound the slack, re-seated the cable in its drum grooves and re-tensioned both sides evenly, then ran the door by hand to confirm the curtain tracked level for its full height. The opener's travel limits and safety reversal were re-set and tested, and the guides lubricated so the door runs freely.
- Cable re-seated on the drum and both cables re-tensioned evenly
- Curtain levelled and checked through full travel
- Opener limits and safety reversal re-set
- Guides and running edges lubricated

Parts & Work Completed

Frequently Asked Questions
Cables only stay on their drums under tension. If the door hits something on the way down, is bounced or forced, or the opener's down-limit is set too far, one cable goes slack for a moment and can walk off. Worn or frayed cables do the same — which is why we check the cable before simply putting it back.
