Single vs double cable cost
A single-cable swap on a door that's otherwise sound is a smaller job than a pair replacement on a door where the drums are grooved and the bottom brackets are bent from the cable letting go under load.

Local causes
Most of the housing in this area went up between 1940 and 2015, with the median build year landing around 1977, and the bulk of that stock dates to the 1960s and 70s across the two dozen named neighborhoods we cover. That matters for cables specifically. A lot of these garages still have their original drums, tracks, and cable runs, and steel cable doesn't age gracefully once it passes the 30-year mark - the individual strands work-harden, fray at the drum, and start shedding thin wire threads you can feel if you run a hand along the loop.
The climate band here is COLD and severe, which means real freeze-thaw cycling every winter. Cable that's already stiff from age gets worse when it's cold: it loses flexibility, kinks at the bottom roller bracket, and is far more likely to snap under tension on a frigid morning than a mild afternoon. We see the pattern every year - a door that worked fine in October seizes or drops unevenly by January because one cable finally gave out.
On a two-cable system, when one side lets go, the door racks sideways in the tracks. That's the failure mode we get called out for most, and it's a direct product of the age of the hardware and the winters it's been sitting through.
Pricing
We don't have a posted price list for cable jobs, because the range is wide and it comes down to whether both cables need replacing, whether the drums or bottom brackets are also worn, and whether the door needs to come off track to get at the far cable safely.
A single-cable swap on a door that's otherwise sound is a smaller job than a pair replacement on a door where the drums are grooved and the bottom brackets are bent from the cable letting go under load.
What we can tell you: if one cable has snapped, we almost always recommend replacing both, even if the second one looks fine. They wear at the same rate, and a mismatched pair means you're back out here in six months for the other side.
That's not upselling - it's just how cable wear works on a two-cable system. Give us the make and rough age of your opener and door when you call, and we can narrow down the likely scope before the truck rolls, so you're not guessing at cost on the phone.
Warning signs
A door that slams down the last foot instead of settling is usually a cable that's stretched or partly frayed and no longer taking even tension.
A door that tilts to one side as it opens or closes, with one corner dropping lower than the other, means one cable has already slipped off the drum or snapped outright - don't run the opener again until that's fixed, because you can bend the track or the bottom brackets forcing it. Loose, frayed wire strands poking out near the bottom roller bracket are an early warning, not something to wait out.
Once a cable starts shedding strands it's shedding load-bearing capacity, and the remaining strands are carrying more weight than they're rated for. A loud bang followed by the door refusing to move at all, with cable visibly hanging loose from the drum, means it's already gone - at that point the springs are still under tension and the door is not safe to force by hand.
If you hear a grinding or clicking sound from one side of the door as it travels, that's often cable rubbing where it shouldn't, catching on a burred drum or a bent bracket, and it's worth a look before it becomes a full break.
Booking
Call and describe what you're seeing - which side dropped, whether the door still moves, and roughly how old the door and opener are. That's enough for us to figure out if it's a single-cable job, a pair replacement, or something involving the drums or brackets too.
Don't try to force the door open or closed once a cable has let go. The other cable and the springs are still under load, and moving the door manually can bend the track or drop the door suddenly. Leave it where it sits and give us a call.

Questions
You can, but we usually don't recommend it. Cables on a two-cable door wear at close to the same rate, so if one has failed from age or fatigue, the other is likely close behind. Replacing both at once costs less overall than two separate visits and avoids a mismatched pair pulling unevenly on the drums.
Cold makes steel cable stiffer and less forgiving. In a severe cold climate like this one, a cable that's already frayed or aged from decades of use is far more likely to fail on a freezing morning than a warm one, because the stiff strands can't flex under the sudden load of the door starting to move.
No. Once a cable lets go, the door is likely off-balance and the springs are still holding tension against a door that's no longer supported evenly. Forcing it by hand risks the door dropping suddenly or the track bending. Leave it and call for a repair.
If your house was built decades ago and the door and opener have never been replaced, there's a good chance the cables are original too. Steel cable doesn't usually last as long as the door itself, so if you don't know the last time they were swapped, it's worth having them checked.
