Why This Fails Locally
Cottage Lake is a small place to service, about 7,876 households, nowhere near the density of the 251,878 households spread across the rest of the area we cover out of Seattle. That matters because a town this size doesn't generate a steady stream of cable calls the way a dense neighborhood does. When we get a call from out here, it's almost always tied to the age of the house, not to volume of traffic on the door.
Most garages in Cottage Lake went up around 1984, which puts them squarely in the era of extension-spring setups with galvanized aircraft cable running over a simple pulley to a lift cable drum, or early torsion conversions bolted onto the same jamb hardware. Thirty-plus years of that same cable flexing over the same pulley groove wears a groove into the cable strands themselves, you'll see fraying right at the pulley contact point long before the whole cable snaps.
Our climate here runs mild with the occasional freeze. That's not the dramatic thaw-cycle stress you'd get somewhere with real winters, but it's enough moisture, most of the year, to rust a cable from the inside out where the strands meet the drum. Rust doesn't announce itself. It just eventually gives.
How We Fix It
When we come out to Cottage Lake, it's about 16 miles from our base in Seattle, the first thing we check isn't the cable itself, it's the drum and pulley it rides on. A cable that's frayed from a burred pulley groove will fray again in a year if we just swap the cable and leave the pulley alone.
On the 1980s extension-spring doors common out here, we replace both cables as a pair even if only one has failed, because if one side went from age and rust, the other side is on the same clock. We check the pulley bracket for wear, re-seat or replace it if the groove is chewed up, and reset the drum height so the door travels level instead of racking to one side.
On the smaller number of torsion setups we find in this area, the fix is different, cable comes off the drum under spring tension, so that part of the job isn't something we rush, and we check the drum-to-shaft set screws while we're in there since loose set screws are what causes a lot of the drum-side cable damage on doors this age in the first place.
Doing It Yourself
A cable under an extension spring or a wound torsion spring is storing real force, and cutting corners here is how people end up hurt, not how they save money. If your door has a torsion spring and drum system, we'd rather you call than open the housing yourself, the tools for winding and unwinding a torsion spring safely aren't something most homeowners have sitting in a drawer, and a spring that lets go while you're working on it can break bones.
What you can reasonably do yourself: look at the cable. If you see rust, kinks, or frayed strands anywhere along its length, especially near the drum or the pulley, that's your sign to get it replaced before it snaps rather than after. A door that's already sagging to one side or hanging crooked in the track is telling you a cable has already partly given way. At that point, don't run the opener. Running a door on a compromised cable is how a cable finishes failing while the door is halfway up, and then you're dealing with a door that's stuck instead of one that's slow.
What It Costs
We don't have a set price to quote here without seeing the door, whether it's a single cable swap on an extension-spring system or a full drum-and-cable job on a torsion setup changes the job enough that a number given over the phone would just be a guess dressed up as an estimate. What we can tell you is that the age of the hardware out here, original 1980s drums and pulleys on a lot of these doors, sometimes means the cable isn't the only worn part, and we'll tell you upfront if the pulley or drum needs replacing alongside the cable rather than adding it on after we've started.
The Symptom
The most common call we get from this part of the service area starts the same way: the door goes up fine but comes down crooked, dragging on one side, or it stops a few inches from the ground and won't seat flush. Sometimes there's a loud pop or snap right before it happens, that's usually the cable letting go at the drum end where the rust has been working on it longest.
A less obvious version: the door looks fine sitting closed, but when it opens it visibly tilts, one corner lifting a half-second before the other. That's a cable that's stretched or partly frayed but hasn't snapped yet, the door is still being lifted, just unevenly, by whatever cable strands are left intact. Either version means the same thing: don't keep opening and closing it while you wait. Every cycle puts more load on whatever's left of that cable.

Questions, answered
How far out is Cottage Lake from your shop?
About 16 miles from our base in Seattle. We travel out to Cottage Lake for cable jobs; we don't keep a separate depot or crew stationed in the area, so scheduling is built around the drive.
Why did my cable snap when the door still looked fine?
On doors from the 1984-era stock common in Cottage Lake, rust builds inside the cable at the drum where you can't see it. The outside strands can look intact while the inner ones have already corroded through, so the failure looks sudden even though it's been developing for years.
Can I just replace one cable if only one broke?
You can, but on a door this age we'd recommend replacing both. If one cable failed from rust or wear, the other side has had the same exposure and the same mileage, and it's usually only a matter of time before it goes too.
Is it safe to open the door if a cable looks frayed but hasn't snapped?
No. A partially frayed cable is still under load and can finish failing mid-cycle, which is more dangerous than a door that's already stuck. Leave the door closed and stop running the opener until the cable's replaced.
