One cable slipping off its drum groove is enough to jam a door mid-cycle or send a panel crashing at an angle. We fix the cable and check why it slipped in the first place.
A single-cable fix often means a second failure soon after. We explain the pair-replacement logic upfront.
Cable replacement without a drum check is an incomplete repair, so we always look at both.
This repair sits close to stored spring energy, which is exactly why licensed handling matters here too.
A same-day fix is standard for cable failures, parts already on the truck.
Each service below is handled by a technician trained specifically for this kind of repair, not a generalist guessing at it.
We replace the snapped cable and its pair, then verify even tension across both sides.
Catching a fraying cable early avoids the sudden, uneven drop that comes with a full snap.
If the cable keeps slipping off the drum, we look for a bent drum or misaligned track causing the repeat issue.
We match new drums to the correct diameter for your door's cable length requirements.
A door hanging crooked usually means one cable or spring has failed while the other holds. We correct both the immediate hazard and the root cause.
Tell us if the door is hanging crooked or jammed, that detail helps us prioritize the call correctly.
Technicians carry standard cable gauges and lengths for most residential doors.
Diagnosis includes the drums, not just the visible cable, before any price is confirmed.
Cables replaced, tension balanced, and the door tested level before we leave, backed by written warranty.
“Door was hanging at an angle after a cable snapped. They replaced both cables and it's perfectly level now.”
“Explained why replacing just one cable wasn't a real fix. Makes sense once you see the wear pattern.”
“Door was jamming mid-cycle for weeks. Cable and drum issue, fixed in one visit.”
One side losing tension while the other holds is the classic sign of a single cable or spring failure.
Both cables typically get replaced together to avoid a near-term repeat call.
Yes, a door hanging on a single cable or spring can drop unexpectedly and should not be operated until repaired.
We check the drum groove condition whenever a cable keeps coming off, since replacing just the cable won't fix a bad drum.
Cost varies with door size and whether one or both cables and drums need attention.
Standard cable and drum stock means same-visit repair is the norm, not the exception.
