The call we get from Burlington is almost never "my cable snapped like a rubber band." It's a door that drops crooked on one side, or hangs an inch low at the bottom corner, with a faint grinding sound as it travels. That's a cable fraying at the drum, not snapping outright, and it's a different failure than the one you'd expect on an older extension-spring door.
Most of the service area's housing dates back to a median year of 1984, with stock going back to 1938. Burlington is newer - most of its houses went up around 1999. That fifteen-year gap matters more than it sounds like it should. Builder-grade doors from this era almost all came with torsion springs and drums mounted on a horizontal shaft over the opening, with galvanized aircraft cable wound tight around each drum. When that cable starts to go, it frays against the drum groove first, strand by strand, long before it lets go completely. On the older extension-spring doors common in the rest of the service area, the failure mode is usually a pulley or a stretched cable loop at the bottom bracket - a different part, a different symptom, and a different fix.
