Rochester, MN · Garage Door Service
Broken or frayed garage door cables on Rochester homes built from the 1940s through the 1990s. What causes it, what a fix runs, and when to call it in.
A snapped cable is not the spring. It's the thin steel wire wound around the drum at each end of the torsion shaft, and it carries the door's weight along with the spring. If one has jumped the drum or frayed through, the door will hang crooked or drop hard on one side, and that side is under load even when the door looks still.
You can look at it. You can tell your tech which side failed and whether the door came down slow or fast, which helps them bring the right cable length on the first trip. What you shouldn't do is unwind the drum, cut the old cable off, or try to re-tension the opposite side yourself. The drums sit on a shaft that's still storing spring force, and backing out the set screws on a wound torsion spring is how people lose fingers, not a figure of speech. If the door is a two-car door with two cables, a failure on one side almost always means the other cable is close behind, since they see the same cycles and the same weather. Replace both, not just the one that broke.
One honest limit: if the drum itself is grooved or the cable jumped and chewed up the winding, that's often a same-visit fix, but if the track's bent from the door dropping unevenly, that's a separate repair and we'll tell you before we start, not after.
We don't publish a flat number for cable work because the job changes with door weight, whether it's one cable or a pair, and whether the drum needs replacing along with the cable. A single-car door with one bad cable and a good drum is a smaller job than a double door where both cables are original and the drums show wear.
What we can tell you: this is a same-visit repair in the large majority of cases. We don't quote cable jobs over the phone without seeing the door, because a cable that looks fine on the low side can be one bad wind from letting go too, and we'd rather tell you that in person than guess low and revise upward once we're there.
Cable failure doesn't usually look like a snap. More often it's a door that starts opening crooked, one corner lifting before the other, or a door that won't fully close and leaves a gap at one bottom corner. Sometimes you'll hear a pop and the door drops an inch or two on one side and stops, held up by the opener or the other cable. If the door is already down when you find it, don't run the opener again. Running a door on one working cable can bend the track or rack the panels, turning a cable job into a door job.
Rochester's housing runs 1947 through 2001, with the bulk of it dating to the 1980s and 90s across the area's 17 named neighborhoods, and that stretch of construction is exactly the range where you find galvanized cables that have never been swapped. A cable doesn't wear out on a schedule, it wears out on cycles and on cold, and this area gets both. In a severe cold climate, steel cable loses flex in winter, and the small amount of stretch that lets a cable ride smoothly over the drum shrinks. Add 30 to 40 winters of that on a door built when the house was, and the strands at the drum end fray from repeated flexing in stiff cable rather than from any one bad day.
Houses from the earlier end of that build range, the late 1940s through 1960s pockets mixed into the area, often still carry original hardware nobody's touched, and those cables are past due regardless of how the door looks from outside. The newer end, 1990s construction, tends to hold up better only because the cable itself is younger, not because the climate treats it any differently.
It rarely happens out of nowhere. Cable frays gradually where it wraps the drum, and cold weather speeds that up because steel cable stiffens and flexes less smoothly in winter. By the time it lets go, it's usually been fraying for months. If your house dates from the 1980s or earlier, original cable is a common culprit.
Don't run the opener again once you notice the door hanging crooked or dropped on one side. The remaining cable and the opener aren't built to carry the door alone, and forcing it can bend the track or twist a panel, which turns a cable repair into a bigger door repair.
On a two-car door, we generally recommend replacing both cables even if only one failed, since they've run the same cycles and the same winters. It costs less to do both now than to pay for a second service call in a few months when the other one goes.
