Across the 53 named areas in this service area - from Wormleysburg two miles out to Hershey thirteen miles away - the housing stock is overwhelmingly 1960s and 70s construction, and that era of garage door hardware wasn't built for the cold band this region sits in. Steel springs and cables from that period don't have the galvanized coatings or fatigue-rated wire that became standard decades later, and severe cold swings are exactly what finishes off a spring that's already lost tension.
That's the pattern across the whole area we cover, not just one neighborhood: a torsion spring rated for a certain number of cycles gets to the end of its life, and a hard overnight temperature drop is often the thing that actually snaps it, because cold steel is less forgiving than warm steel. We see the same failure in Harrisburg itself and in the towns around it, because the building era and the climate are the same across the region - it's not a house-by-house fluke, it's the hardware age catching up with the weather.
