Great Falls is a small place as these things go, about 4,970 households, which means the emergency calls we get from here don't cluster the way they do in a bigger grid of streets. There's no single failure that defines the town because the housing stock isn't uniform block to block, but the median build year sits around 1985, and that's the number that matters most for repair work. A door and opener installed in the mid-1980s is now on its third or fourth spring cycle if it's been maintained at all, and on its original torsion hardware if it hasn't. That hardware wasn't built for forty years of Virginia winters. Cold, dry air stiffens lubricant and shrinks metal tolerances just enough that a spring already fatigued from age will let go on the first hard freeze of the season. We also see openers from that era with gear-sets that were never rated for the heavier insulated doors homeowners have swapped in since. The combination of original-era torsion springs and later-generation doors is the pattern we actually see out here, not a single cause but a mismatch between two decades of parts sharing one bracket.
