Garage Door Cable & Drum Repair
One corner sitting lower, or a cable hanging off its drum, means the lift system is out of balance. It wants looking at before the next cycle, not after.
What this involvesStop using the door
Broken, frayed, or loose lift cable
A cable is loose, frayed, hanging, or broken.
Stop using the door. This is one of the symptoms where the next cycle can do real damage — to the door, or to whoever is standing near it. Keep people, pets, and vehicles clear until someone has looked at it.
Right now
What to do before anyone arrives.
Short list, and none of it involves touching the door.
- Keep people, pets, and vehicles clear of the door until it is assessed.
- Stop cycling or forcing the door.
Whatever you do, don't: Do not loosen, wind, cut, or remove springs, cables, drums, or bottom brackets.
Be careful here
A good clue is still not a diagnosis.
A cable is loose, frayed, hanging, or broken.
The catch is that the same behaviour can come from more than one place — the door itself, the opener, the controls, or the safety system — and they interact. That's exactly why a confident phone diagnosis should make you suspicious rather than reassured.
Someone needs to watch the door travel its full path before saying what failed. We won't use one symptom to invent a part, a price, or a reason you need a whole new door.
Where this usually lands
The repair this points to.
Likely, not certain. Worth reading so you know what a fair scope looks like.
Off-Track & Stuck Door Repair
Every extra cycle bends another panel and drags more cable out of line. Leave it where it is, keep the opening clear, and get it stabilized properly.
What this involvesQuestions
Safety first, then everything else.
What does broken, frayed, or loose lift cable usually look or sound like?
A cable is loose, frayed, hanging, or broken.
Can I fix broken, frayed, or loose lift cable myself?
Do not loosen, wind, cut, or remove springs, cables, drums, or bottom brackets. Springs, cables, drums, bottom brackets, and any door that is already unstable can release stored energy without warning — this is where the serious injuries in this trade come from. Everything else on the door is fair game.
What should I do right now?
Keep people, pets, and vehicles clear of the door until it is assessed. Stop cycling or forcing the door.
Does this tell me which part has failed?
No, and be wary of anyone who says it does from a description alone. This tells you what the symptom means and whether the door is safe to use. Someone still has to look at the whole door before committing to a part or a price.
Not quite it?
Compare what you're actually seeing.

Get this one looked at.
Describe what the door is doing, from somewhere safe. You'll be told what actually failed and what it costs before anyone starts, it's free to ask, and you're free to say no.
