How We Fix It
Most doors on this side of the plateau are steel sectional units on torsion springs, hung on galvanized lift cables that run down each side to a cable drum at the top of the track. That's the standard setup for houses built around the median year here, 2001, builders were putting up two-car garages with 16x7 double doors or 8x7 singles, and the hardware that came with them was mass-produced torsion-and-cable, not the older extension-spring rigs you find on pre-1980s stock. When a cable frays or snaps, we release tension on the spring first, pull the old cable off the drum, and run a new one matched to the drum size and door weight. On a double door we check both cables even if only one failed, because they wear at close to the same rate. We reset track alignment and cycle the door a dozen times before we call it done.
The Symptom
The most common call from this area is a door that drops crooked on one side, or a bang followed by the door refusing to move at all. That's a cable that's let go, usually where it wraps the drum or where it clamps to the bottom bracket, both spots take repeated flex over two decades of daily openings. You might also notice the door sticking partway up, or a cable visibly frayed with wire strands sticking out like a broom. Don't keep hitting the opener button once you see that; a cable under load that finally snaps can drop a heavy steel door fast. If the door still moves but sounds rough or pulls to one side, that's often the early stage of the same wear, and it's worth a call before it becomes a stuck door on a Saturday.
What It Costs
We don't have a fixed number to publish for this area specifically, and we're not going to guess at one just to fill space. Cable repair pricing depends on whether it's a single door or a double, whether both cables need replacing, and whether the drums or bottom brackets took damage when the cable let go, that gets assessed on site. What we can tell you is that a straightforward cable swap on a double door is a smaller job than a full spring or opener replacement, and if we're already there for a cable, we'll flag anything else that's close to failing so you're not paying for two separate trips.
What Is on the Truck
For cable work we carry galvanized lift cable in the standard gauges used on residential sectional doors, spare cable drums, bottom brackets, and the clamps and fasteners that go with them. We also carry winding bars and vise grips for safely relaxing torsion spring tension before touching a cable, that part of the job isn't optional, it's how the repair gets done without anyone getting hurt. What we don't carry is oddball parts for doors that were custom-built or heavily modified; those sometimes need an order, and we'll tell you upfront if that's the situation rather than pretend we can finish it in one visit.
Why This Fails Locally
This area's housing stock is younger than a lot of the neighborhoods we cover, median build year 2001 against a median closer to 1982 across the wider service area, so the failure mode here is less about ancient one-piece doors and more about cables that have simply put in twenty-plus years of cycles on the original hardware. With 8,555 households out this way and a median income of $181,820, we see a fair number of upgraded openers bolted onto the original cable-and-drum setup, which puts more strain on cables that were never swapped out. The climate here stays mild with only occasional freeze, so we're not dealing with ice-locked doors, but humidity and thermal cycling still work on galvanized cable strands over time, same as anywhere in the region.

Questions, answered
Is a snapped cable dangerous to deal with myself?
Yes. A torsion spring holds real tension, and a cable failing under that load can whip or let the door drop suddenly. If a cable has snapped, leave the door where it is, don't force the opener, and call for a repair rather than attempting it yourself.
Do both cables need replacing if only one snapped?
Often, yes, especially on a double door. Both cables usually see similar wear over the years, so if one has failed from age, the other is often close behind. We'll inspect both and tell you honestly if the second one looks fine.
How far out is Union Hill-Novelty Hill from your base?
It's about 16 miles from our Seattle location. We travel out for cable repairs same as our other service calls; there's no separate branch here, just a truck making the drive.
Will my opener need work too if a cable breaks?
Not usually. The opener drives the door once the cable-and-drum system is doing its job; a snapped cable is a mechanical failure separate from the opener motor. We check the opener while we're there, but most cable jobs don't touch it.
