Uneven lift on one side
Some owners notice the door suddenly feels heavier on one side when they lift it manually, which usually means one cable is already carrying less load than it should.

Rapid City, SD
Broken or frayed garage door cable in Rapid City? We explain how to book a repair, what drives the cost, and why cold winters snap cables on older local doors.
Booking
Call and tell us what you're seeing: a door that won't lift evenly, a cable hanging loose off the drum, or a bang followed by the door dropping crooked.
That description tells us whether it's a snapped cable, a frayed one about to go, or something bigger like a bent drum or off-track roller riding on it. We work across the Rapid City service area, out to Rapid Valley, Green Valley, Colonial Pine Hills, Box Elder, Summerset, Keystone, Hermosa, New Underwood, and Hill City, so when you call, give us your town along with the symptom.
A door with one cable snapped is still under spring tension and can drop fast or kick sideways - don't try to force it open or closed, and don't put your hands near the drums. Leave it where it sits and give us a call.
We'll get a truck routed to you and walk you through what's safe to do in the meantime, which is usually nothing more than keeping the door down and leaving the opener alone until we're there.
Pricing
We don't post a flat number for cable repair because the job isn't the same from one house to the next. A single frayed cable on a light single door is a different job than two cables on a heavy insulated double door, and if the drum or the bottom bracket got damaged when the cable let go, that's additional parts. What we can tell you is the honest limitation: if you call with a drooping door and we find the cable snapped because it rusted through at the bottom fitting, that's a straightforward swap. If the spring went first and took the cable with it, or the drum is scored, the job grows. We quote on the phone once we know what's actually wrong, and we confirm it in person before any work starts, because guessing a price over the phone on a job we haven't seen is how a homeowner ends up surprised.
Local causes
Most of the houses in this service area went up between 1972 and 2007, with the heaviest concentration from the 1980s and 90s spread across the nine communities we cover. A door installed when a house was built in, say, 1989 has had three-plus decades of cold-season use on its original cables, and this area sits in a severe cold climate band. Cold doesn't just make steel brittle - it drives repeated contraction and expansion at the cable's end fittings every time the door cycles on a frigid morning, and that's exactly the kind of flex that frays a galvanized cable from the inside out, often with no visible warning until a strand gives. Across 10,745 households and 5,739 owner-occupied houses in this area, a lot of garages are sitting right in that age window where the original hardware is simply due. It's not a defect in any one door - it's thirty-plus winters doing what winters do to steel cable that was never meant to last the life of the house.
Warning signs
A cable failure rarely looks like a clean snap on day one. Before it lets go, you'll often notice the door hanging slightly crooked when it's down, one side a half-inch lower than the other, or a faint fraying sound as the door travels - a light clicking or scraping near the bottom bracket where the cable meets the drum.
Some owners notice the door suddenly feels heavier on one side when they lift it manually, which usually means one cable is already carrying less load than it should.
Once a cable actually breaks, the door typically drops hard on that corner, sometimes jumping the track, and the opener may still run while the door itself goes nowhere useful.
If you catch the early signs - the lean, the clicking, the uneven lift - that's the point to call, because a cable swapped before it breaks is a simpler job than one replaced after it's taken a track or bracket with it.
Questions
If the door is down and a cable snapped, leave it closed and call us rather than trying to open it. A broken cable means the door is unevenly supported under spring tension, and forcing it up risks the door jumping the track or dropping suddenly. If the door is already stuck partway open, don't put yourself under it.
Garage doors run two cables, one on each side, and they generally see the same tension and the same winters. We'll inspect both when we're out, and if one shows the wear that led to the failure, we'll usually recommend replacing the pair so you're not back out here in a few months for the second one.
Rapid City sits in a severe cold climate band, and cold steel is less forgiving under repeated flex. A cable that's been fraying slowly for years tends to give out on the coldest mornings, when the metal is stiffest and the door is working hardest against the cold-tightened spring.
