How It Shows Up
A cable failure rarely looks dramatic until it is. The first sign is usually a door that hangs crooked - one side drops lower than the other because one cable has gone slack or frayed through. Sometimes you hear it before you see it: a sharp snap, then the door won't lift past a few inches, or it comes down fast and uneven when you didn't touch the opener. On older torsion setups, which are common in homes built around the early 1970s like a lot of the Falls Church stock, the cable runs off a drum at each end of the shaft - when one side lets go, the whole panel racks sideways. If you see fraying at the bottom roller bracket or notice the door binding in the track on one side only, that's a cable on its way out, not yet gone. Don't keep running the opener through it. A half-snapped cable under load is how a spring takes out a track, or worse, how someone gets hurt reaching under a door that isn't actually secured.
What Can Go Wrong
Cable wear and cable snap aren't the same failure. Wear shows up as fraying strands near the drum or the bottom bracket - you can catch it early if you're looking. A clean snap, usually right at a crimp point or where the cable rubs a pulley, gives no warning. In a 1970s-era house, the original hardware was often sized for a lighter wood door; if a prior owner swapped in a heavier insulated steel panel without upsizing the cable and spring together, the mismatch shortens cable life substantially. We also see galvanized cable that's simply outlasted its rated cycles - it's not glamorous, it's just age. The failure that costs more than a cable: letting a door run on a half-frayed cable until the drum itself chews up, which turns a $150-range cable job into a shaft and drum replacement. We won't talk you into replacing parts that aren't failing, but we also won't recable a drum that's already scored - that's a repair that doesn't hold.
Stocked Parts
We carry standard-gauge galvanized lift cable, common cable drums, and the fittings that match torsion hardware from the era most Falls Church doors were built in, so a straightforward snap doesn't turn into a special-order wait. What we don't keep on the truck: cable sized for unusually heavy custom doors or drums for openers that were discontinued years ago. If your house has had a non-standard door installed at some point, we'll tell you upfront if that means a return trip for a part instead of a one-visit fix. That's the honest limitation - we'd rather say that than quote you a time we can't hit.
Booking a Visit
If your door is hanging uneven, won't lift past a few inches, or you heard a snap, call before you keep cycling the opener on it. We come out from our Arlington location, about four miles to Falls Church, to look at the cable, the drum, and the spring together - a cable rarely fails alone, and checking the whole lift assembly on one visit saves you a second truck trip.
