What Can Go Wrong
Houses going up here in the early 1960s were built with galvanized steel track, extension springs mounted overhead, and hinges rated for lighter doors than what's often hung on them now after a wood-to-steel swap. None of that hardware was designed with the safety cables or reinforced end brackets that became common decades later, so when a roller wears thin or a bottom bracket loosens, the panel can walk out of the track instead of staying contained. A door in West Falls Church going off-track is just as often a bent track rail from age as it is a broken cable - the two look similar from the driveway but need different repairs. Severe cold snaps add another failure point: steel contracts, lubricant stiffens, and a track that was already a hair out of plumb binds a roller hard enough to pop it loose. We also see this on doors where a previous owner added an opener without checking whether the original track and hinges could handle the extra travel cycles. None of that is unique bad luck - it's what 1960s hardware does under modern use.
What the Repair Takes
Most off-track jobs here split into two kinds of work: resetting a door that slipped a roller but the track itself is straight, and replacing a section of bent track where the rail has to come off the jamb entirely. The first is usually a same-visit fix - back the door onto the rail, reset the roller, check the bracket bolts for the wear you'd expect on original 1960s hardware. The second takes longer, because matching track depth and bracket spacing on an older frame isn't always a straight swap from a current parts box, and in a handful of cases we've had to order a section rather than carry it on the truck. We'll tell you up front if that's the case rather than make a return trip look like a surprise. One limitation worth saying plainly: if the door came off because a spring let go at the same time, we're not going to force it back onto the track under tension - that gets re-sprung first, then reset, because doing it the other way around is how someone gets hurt.
