Doing It Yourself
A snapped cable looks simple until the door is sitting crooked in the opening with one side higher than the other. On a house built in 2001 or later, like most of what's in Roxborough Park, the cable usually comes off a factory-installed drum at the end of the torsion shaft, and that drum has to be re-seated and the cable re-wound under tension before the door will travel straight again. This is not a job for channel-lock pliers and a Saturday afternoon. The shaft is under spring load, and if you back out the wrong set screw, that shaft can spin and take a finger with it.
What you can safely do: leave the opener disconnected, prop the door with locking pliers below the bottom roller so it can't slide further down the track, and don't try to force it closed by hand. If the cable has frayed but not snapped yet - you'll see wire strands poking out near the drum - that's a warning sign worth a call before it lets go completely, not an afternoon project.
What Is on the Truck
For a 2001-and-newer build, the cable stock that matches is usually standard 1/8-inch aircraft cable sized to a 7-foot or 8-foot door, which covers most of what went up in this area during that building wave. We also carry replacement drums, since a cable that's jumped the drum groove more than once has usually worn a groove of its own and needs the part swapped, not just re-wound.
What we don't carry on every truck: cable for older torque-master or center-mounted shaft systems, which show up more in the pre-1980s stock elsewhere in the service area but are uncommon on a house this age. If your door turns out to run one of those less common setups, that part may need to be ordered, and we'll tell you that on the spot rather than stretch a repair to fit what's already in the van.
What You Pay
Cable repair on a standard torsion-spring door with factory drums is a bounded job
Two cables, two drums if needed, re-balance the door, test it under the opener. What changes the number is whether one cable broke or both, and whether the drum itself needs replacing versus just re-winding. We quote it on-site once we've got the door open and can see the drum and shaft condition, not over the phone from a guess.
We don't add a surcharge for the 8-mile drive out from Highlands Ranch
And we don't pad the invoice for a second cable if the first one let go from age rather than abuse - both usually fail close together on a door this age, since they were installed the same year.
How Long You Are Without the Door
Once we're on-site, a straightforward two-cable replacement with drums in stock is typically done inside a couple of hours, including re-balancing the door and running it through a full cycle test. The door doesn't need to sit half-open overnight waiting on a part for this kind of failure, since the hardware is common enough that we stock it.
The one thing that stretches the timeline is cold. Roxborough Park sits in the same severe winter climate band as the rest of the service area, and cable that's gone brittle from months of sub-freezing nights can snap a second strand while we're mid-repair on the first. That's not common, but it's why we don't promise a fixed clock time until the shaft is open and we can see what the cold has done to the rest of the hardware.
The Symptom
The giveaway on a house this age is almost never rust - the cable itself usually still looks clean. What you'll notice instead is the door racking sideways as it closes, one bottom corner dropping faster than the other, or a loud bang followed by the door refusing to move at all. That's consistent with a drum-mounted cable jumping its groove or finally parting after repeated small slips, which is the more common failure pattern on 2001-and-newer torsion systems than the frayed, sun-rotted cable you'd see on an older door.
If the opener still hums but the door won't lift, or lifts only a few inches before stopping, don't keep hitting the remote. That repeated strain against a jammed cable is how a bent track or a cracked bottom panel section gets added to what started as a one-part fix.
