Union's housing stock centers on 2005, newer than the service area's overall median of 1984. That matters more than it sounds like it should. A door that went up in 2005 came standard with a steel sectional panel, a torsion spring mounted above the opening, and an opener with a photo-eye safety sensor built in from the factory. The failures we see here aren't the one-piece wood door hardware or the side-mounted torsion setups you find on the older streets closer to the river. They're torsion spring fatigue after a decade and a half of cycles, worn nylon rollers, and opener logic boards or sensors that finally give out after years of Kentucky winters. Union also runs at a much higher median household income than the territory average, $139,013 against $80,814 - which tends to mean two-car households putting real daily cycles on both doors, and owners who replace a tired door instead of nursing it along for another five years. We still see the occasional cold-snap spring snap, same as anywhere in this climate band, but the cause is wear, not an aging design.
