What Can Go Wrong
Most of the calls we get from Oakton involve a cable that's jumped its drum or frayed through where it wraps the bottom bracket. That's not random. A big share of the houses in this part of our service area went up in the early 1980s, and a lot of those garages still carry the extension-spring setup that was standard for that build era, two cables, one on each side, running up to pulleys instead of winding onto torsion drums. Those cables see more flex and more rust over forty-plus years than a torsion setup does, and once the galvanized coating wears through, the strands start to go one at a time until the door drops on one side.
We also see cables that have simply stretched and slipped off a worn drum groove, which looks like a snapped cable from across the garage but is a different, cheaper fix. Cold winters here don't help either, a stiff cable that's already thinning is more likely to catch and snap on a morning when the metal has contracted. If your door is hanging crooked, or one side dropped fast while the other side held, that's almost always a cable, not a spring, and it's worth knowing the difference before anyone quotes you.
How to Book
Call or send the request through this site and tell us what you're seeing, a door hanging cockeyed, a loud snap, a cable visibly unwound from the drum. We're not based in Oakton; we run out of Reston, about 5 miles off, so we ask a couple of questions up front to bring the right cable stock rather than guessing on-site. If you can, snap a photo of the drum and the bracket before you call. It saves a trip back to the truck and it tells us whether we're dealing with a snapped cable or a slipped one, which changes what we load.
Stocked Parts
We carry the standard 7×19 galvanized aircraft cable in the lengths that fit the extension-spring doors common on 1980s-built Oakton garages, plus the drums, pulleys, and bottom brackets that usually go with a cable failure on that hardware. What we don't stock on the truck is anything oddball, a cable cut to a nonstandard length for a custom or oversized door, or hardware for a torsion conversion someone did years back without matching parts. If your setup turns out to be one of those, we'll tell you on-site rather than force a part that doesn't fit, and that sometimes means a second visit once the right length is in hand.
What It Costs
We don't post a flat number for cable repair here because the job splits into two very different scopes: a single frayed cable on one side of a standard extension-spring door, versus both cables plus a bent bracket or a chewed-up drum after the door's been run on a snapped cable for a day or two. The second scope costs more in parts and time. We'll give you the actual number after we look at the drum, the bracket, and how the door's been tracking, not before.
What the Fix Involves
With the door secured and the springs released of tension, we pull the old cable off the drum and bracket, check the drum groove and pulley for wear grooves that could chew through a new cable in a year, and run new cable matched to the door's weight and travel. On the extension-spring doors typical of this area's early-1980s stock, that means resetting both side cables evenly so the door doesn't rack sideways when it opens, a common miss if only one side gets replaced. We test the balance by hand before we ever run it on the opener, because an opener will mask a cable problem right up until it burns out the motor trying to force a door that isn't hanging straight.
Time on the Job
A straightforward single-cable swap on a standard door usually runs under an hour once we're on-site. If both cables need replacing, or the drum and bracket took damage from running on a broken cable, plan on longer, we're also checking track alignment and hinge wear at that point, since a door that's been out of balance for even a short stretch tends to loosen other hardware along the way.

Questions, answered
Why did my cable snap with no warning?
On the extension-spring doors common in Oakton's early-1980s housing stock, cables wear from the inside, rust and fraying happen where the strands flex around the drum and bottom bracket, out of sight. By the time you hear the snap, the cable's usually been thinning for a year or more. There's rarely a single cause you'd have noticed.
Can I drive my car out if a cable snapped overnight?
If one cable let go, the door is likely hanging unevenly or jammed partway in the track. Don't force the opener or try to lift it by hand past the point it's stuck, that can bend the track or bracket further and turn a cable job into a track and bracket job. Leave it and call.
Do you carry the right cable for older Oakton garages on the truck?
Yes, for standard extension-spring setups typical of the area's early-1980s builds we carry the cable, drums, and brackets on the truck. Custom-length cable for an oversized or modified door isn't something we stock, and we'll flag that on-site rather than force a fit.
How far out is Oakton from your base?
We run out of Reston, about 5 miles from Oakton, so there's a short drive built into any visit. We ask what you're seeing over the phone first so we bring the right cable and hardware rather than diagnosing cold in the driveway.
