Cable repair for Damascus homes built around 1983, where original galvanized cable and cold-weather corrosion are the usual cause of a dropped door.
A snapped cable looks simple until you're standing under a 150-pound door with no idea what's holding the other side up. On a Damascus house from the early 1980s, that door is almost always original or one replacement in, which means the cable drum, the track, and the spring anchor are all matched to hardware nobody sells off the shelf anymore. Swap one part with a mismatched modern piece and the door binds or the new cable frays again in a season. If a cable has already let go, the door is not stuck safely - it's held by whatever tension is left in the other cable and the springs, and that can shift with a bump or a gust. We're not going to tell you how to wind a torsion spring or thread a drum in a page like this. That's not caution for its own sake, it's the actual job. Where you can help yourself: don't force the opener, don't yank the door by hand, and don't cut the slack cable to get the door to sit flush - that's usually what turns a $200 job into a full hardware replacement.
Most Damascus calls for this are a single broken cable on a door that's 30 to 40 years old, going by the 1983 median build year out here - older on average than the newer subdivisions closer to Gaithersburg. That age matters: cable, drums, and end bearing plates from that era were built to a spec that doesn't match current stock exactly, so the tech carries adapters and sizes a straight parts-store cable often won't have. The job itself is a cable swap, a tension check on both sides of the shaft, and a look at the drum and bottom bracket the old cable was riding on, since a frayed cable is often a symptom of a burred drum, not the cause. On a double door we check both cables even if only one broke - if one failed from age, the other is close behind.
We don't have a fixed number to publish here, and giving you a guess wouldn't help you plan. What we can tell you is what moves the price: whether it's one cable or a pair, whether the drum or bottom bracket needs replacing along with it, and whether the springs need rebalancing after. A straight one-cable swap on a door that's otherwise sound is the cheap end of this repair. A cable that snapped because a drum groove wore through, on a door old enough that the drum is no longer stocked, runs longer because that part has to be sourced or fabricated to fit. Ask for the breakdown before the work starts, not after.
The failure we see out here isn't the cable itself, it's what a broken cable did on the way down. On an unbalanced door, a snapped cable lets the opposite side drop hard and rack the track out of alignment, which turns a cable job into a track and roller job. On some 1980s-built doors we still find non-galvanized cable from an earlier repair, and that's the cable that goes first every time a cold snap hits. The other place this goes wrong is DIY tension work on the remaining cable - loosening it to make the door 'sit right' instead of replacing the broken side, which leaves the door running on borrowed time on both cables instead of one.
The door drops crooked, one corner hanging lower than the other, or it won't move at all and the opener strains against something that feels solid. Sometimes you'll hear the snap - a loud pop from inside the garage - and then the door sags on one side like a rope let go, because that's exactly what happened. If the door was already partway open when the cable broke, it may hang at an angle instead of dropping shut, held by the opener arm and whatever's left of the track engagement. Either way, that's not a door to run through its cycle again until the cable's replaced.
Cold-climate winters put real stress on garage door cable, and this area sits in a severe cold band where repeated freeze-thaw cycles work moisture into any nick or fray in the cable jacket, then expand it. On a house built around 1983, that cable has had four decades of that cycle, more if it's never been replaced. Add a household income here near $153,994 and a housing stock that, across the wider region, runs from 1948 to as recent as 2015 with a median closer to 1980 - Damascus sits right in that older band, not the newer end. Older cable on older hardware, worked by decades of hard winters, is the exact combination that snaps.

Not always, but treat it as urgent. A door held by one cable and a spring can shift without warning. Don't run the opener, don't park under it, and don't leave it half-open until it's looked at.
On most doors we replace both cables at once, since they wear at the same rate and a second failure soon after the first is common, especially on doors from the early 1980s that have already had four decades of winters.
Usually, yes, once the cable is replaced and the door is rebalanced. If the opener strained hard against the broken cable before it was caught, it's worth a separate check of the gears and drive - that's a different job, not part of a cable repair.
