Gaithersburg, MD · Garage Door Service
Cable repair for North Potomac's 1988-era garage doors, built with lift cables that stretch and fray with age. Serving North Potomac from 4 miles away in Gaithersburg.
The most common call we get from North Potomac is a door that drops crooked on one side, or won't lift past a foot before the opener strains and stops. That's a lift cable giving out - usually frayed strands near the bottom bracket, sometimes a cable that's jumped its drum. On a two-cable setup, one side lets go first, and the door racks sideways in the track until it jams.
The typical North Potomac house went up around 1988, which puts most garage doors here on galvanized aircraft cable and steel drums that are now well past their expected working life. Cable doesn't fail all at once - it frays a strand at a time under repeated flex, and by the time you hear a snap or see the door hang crooked, it's been wearing for years. Homes built in this window often still have their original hardware if no one's touched the door since move-in, which means the cable, drum, and often the springs are all the same age and all due at once.
A straight cable replacement - one or both lift cables, same gauge and length as what's on the door - is a contained job on most single or double doors. Cost climbs if the drum is grooved from the frayed cable riding wrong, or if a spring let go at the same time and took the cable with it, which happens more often than people expect on original 1988-era hardware that's never been serviced.
We quote after we see the door, not before, because the difference between a clean cable swap and a cable-plus-drum-plus-spring job is significant and we're not going to guess on your driveway. North Potomac's household income runs well above the wider service area median, and we've found that translates to more owners asking for full hardware inspection rather than a patch - worth mentioning if you want the quote to include a look at the springs and rollers while we're already there.
Cold makes steel cable brittle and less forgiving of the fraying it's already doing. This region sits in a cold-severe climate band, and the freeze-thaw swing that comes with it stiffens cable strands and hardens the grease on the drum, so a cable that's marginal in October can snap outright on the first hard cold snap. We see the calls cluster that way every year.
Add to that a door built in 1988 that's still running its original cable thirty-plus years later, and you've got wear plus cold working against the same part at once. It's not a design flaw - cable is a wear item on any door of any age - but a house this age in this climate is due, whether or not anything looks wrong yet.
We work out of Gaithersburg, about 4 miles from North Potomac, so we're not routing a truck across the county to get to you - it's a short run. Call and describe what the door's doing: crooked, stuck, cable visibly loose or snapped. That tells us whether to bring a standard cable kit or plan for a drum and spring inspection too.
We don't stock every gauge and length of cable on the truck for every make of door, so if yours is an unusual size we may need to confirm the part before the visit. That's the one thing that can add a day to an otherwise same-visit repair. See our North Potomac service area page for what else we cover nearby.
Once we're on site, a standard cable replacement runs the door through several test cycles after the new cable is set and tensioned evenly on both sides - that's what keeps it from racking again in a year. We check the drum for grooving and the spring for matching wear, since a new cable on a worn drum just repeats the failure sooner.
If the door's original 1988 hardware is showing wear across the board - drum, spring, and cable all at once - we'll say so plainly rather than replace one part and send you back out for another call in six months. Sometimes the honest answer is that the cable job is the easy part, and the springs are the real reason the door's been fighting the opener.

Most houses in North Potomac were built around 1988, and a lot of those doors are still running original lift cables, drums, and springs if nobody's replaced them. That's well past the point where cable fatigue is a real concern, even if the door still looks fine.
This area sits in a cold-severe climate band, and cold makes steel cable stiffer and more prone to snapping where it's already frayed. A cable that's been quietly wearing for years often lets go on the first hard cold snap of the season rather than gradually.
No. We work out of Gaithersburg, about 4 miles away, and drive out for jobs in North Potomac. There's no local depot or drop-in location here, just a short truck run to reach you.
Lift cables are under spring tension and a mistake here can snap back hard enough to cause real injury. We don't recommend a DIY cable swap on a torsion or extension system - it's a job that wants the door secured properly before anything comes loose.
