Getting It Booked In
Call and tell us what the door is doing: won't budge, hangs crooked on one side, or dropped suddenly with a loud snap. Those three descriptions point to different cable failures, and knowing which one you've got before the truck rolls means we bring the right drum, the right length of aircraft cable, and the right clamps instead of guessing.
A cable job on a standard torsion-spring door is usually a same-visit repair. If the drum itself is cracked, or the track got bent when the cable let go and the door dropped unevenly, that's a second part and sometimes a second trip, because we don't stock every drum size on every truck. We'll tell you on site, not after the fact.
Don't try to lift the door past a snapped cable to get the car out. A door with one cable gone is under uneven spring tension and can rack sideways or come off the track entirely. Leave it where it sits and call.
Why This Fails Locally
Housing across this service area runs 1943 to 2012, with a median build year of 1964, and most of it - the 1960s and '70s tract stock that makes up the bulk of these neighborhoods - was built with steel cable drums and galvanized strand that were never meant to outlast the house by half a century. That's the cable doing its job for sixty-plus years before it finally gives.
The mild temperate climate here isn't the villain the way it is in places with hard freezes - we don't get the brittle-metal snap that comes from deep cold. What we get instead is slow fatigue: thousands of lift cycles on a cable that was installed when the house was new and never once replaced, strand by strand, until one morning it's not. Add a drum that's worn its groove uneven from the same decades of use, and the cable starts riding wrong before it ever breaks.
This is a wear pattern, not a weather event, which is why it shows up steadily across the service area rather than all at once after a storm.
The Symptom
A door that drops hard on one corner, or won't lift past a few inches before stalling, is telling you a cable has let go or is about to.
Bang before cable breaks
Listen for a sharp bang or snap right before it happens - that's the cable strand giving way under tension, not the opener motor. If the door looks crooked in the frame, hanging lower on one side than the other, one cable is still holding while the other has failed or stretched past where the drum can take it up evenly.
Never run the opener
Don't run the opener to try to level it out. That puts the full load on one cable and one drum, and it can bend the track or pull the roller bracket loose.
Frayed strands as warning
Frayed strands visible along the cable near the bottom bracket are the warning sign before the break, not after. If you catch it there, it's a planned repair instead of an emergency one.
What the Fix Involves
We release spring tension safely, pull the old cable and drum as a set, and install new cable sized to your door's weight and track height - not a universal length cut short.
Matched drum pairs
Drums get replaced in pairs even if only one failed, because a worn original drum and a new one spin at slightly different rates and that mismatch is what causes the next cable to fail early.
Bracket damage inspection
We check the track and roller brackets for damage from the drop itself before closing the job out. A door that fell crooked can tweak a bracket just enough that it won't show until the next cable starts to go.
Full hardware replacement
One honest limit: if the drum, track, and spring are all original 1960s stock and one more part failed on top of the cable, replacing the whole hardware set is sometimes the better call. We'll price both ways and let you decide.
