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.
When one lift cable fails, the other has seen the same wear cycle. We replace both to prevent a repeat call.
Cable replacement without a drum check is an incomplete repair, so we always look at both.
Lift cables connect directly to spring-loaded drums, so replacement requires the same careful tension handling as spring work.
Cable stock in standard gauges means most replacements happen in a single visit.
Each service below is handled by a technician trained specifically for this kind of repair, not a generalist guessing at it.
A snapped cable leaves the door hanging unevenly on the remaining side, an unsafe condition we treat as priority.
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.
Correcting an uneven lean means addressing the cable, checking the spring pair, and confirming the track is still square.
A quick description of the lean or jam gets the right cable gauge loaded before arrival.
Cable stock on the truck means most calls avoid a second trip for parts.
We check both cables and the drums together, then quote a flat price covering the full fix.
Cables replaced, tension balanced, and the door tested level before we leave, backed by written warranty.
“Cable kept jumping the drum every few cycles. Turned out the drum itself was cracked, replaced and fixed.”
“Caught the fraying cable during a routine call before it actually snapped. Appreciated the heads-up.”
“Door was jamming mid-cycle for weeks. Cable and drum issue, fixed in one visit.”
This almost always means one lift cable or spring has failed while the other side is still holding weight.
Both cables typically get replaced together to avoid a near-term repeat call.
We treat cable failures as priority calls given the safety risk involved.
Usually a bent or worn drum groove, sometimes combined with a slightly loose cable tension setting.
Cost varies with door size and whether one or both cables and drums need attention.
A snapped-cable call usually resolves in under two hours on-site.
