Doing It Yourself
A frayed or snapped lift cable looks simple from the garage floor. It isn't. The cable is under load from a wound torsion spring, and in North Potomac that spring is usually original to a door installed somewhere between the late 1980s and mid-1990s, when this area was built out. Thirty-plus years of winding and unwinding leaves the spring with stored tension that doesn't care how careful you are.
People get hurt trying to unspool a cable off a drum by hand, or they get the door halfway up on one side and it jumps the track. If one cable has already let go, the other one is close behind it - they wear on the same schedule because they do the same work every day. We're not going to pretend this is a YouTube afternoon. It's a call.
What Is on the Truck
For a cable job on a North Potomac door, the truck carries galvanized aircraft cable in the standard lift lengths for a residential torsion system, replacement drums when the groove has worn oval, and a stock of torsion springs sized to the two-car openings common on houses from this build era.
Common fittings on hand
We also carry the fasteners and end fittings these doors actually use, because the hardware on a 1988-built door is a known quantity by now, not a guess.
Modified doors need return trips
What we don't carry is custom or oversized cable for a door that was modified after the fact - if someone added a different track or opener setup years back, that sometimes means a return trip once we've seen it in person.
How It Shows Up
The usual pattern: the door drops crooked, hangs at an angle, or won't move past a few inches before the opener strains and reverses. Sometimes you'll find the cable itself pooled loose at the bottom bracket, which means it's already off the drum and the door is being held by the other side alone - don't run the opener again until that's fixed.
Cold weather makes it worse. This area sits in a climate zone with real winter severity, and a cable that was already fraying tends to finally give on the coldest morning of the week, right when the garage door gets used the most.
Where This Job Goes Sideways
The job gets harder when the drums are worn enough that a new cable won't sit right in the groove, or when the spring itself needs replacing at the same time - which is common once a system has been running that long.
Skipping the drum replacement
Trying to save money by replacing only the cable and leaving a worn drum in place just means another call in a year.
Opener gear damage risk
The honest limit here: if the opener has also been straining against this problem for weeks, there may be gear or chain damage on top of the cable issue, and we won't know the full scope until we're looking at the unit open. We'd rather tell you that upfront than quote blind.
Booking a Visit
Potomac Garage Door Pros runs this job out to North Potomac, about 6 miles up the road, as part of the regular service area. There's no local branch here - the truck comes from Potomac - so when you call, tell us what you're seeing: a sagging door, a loose cable, a door that won't budge. That helps us load the right spring and cable sizes before we leave.
See the North Potomac service area page for what else we cover nearby, or the Potomac cable repair page for the base rundown on how this repair works.
