A door installed when Vinings was built out in the early-to-mid 1990s is now 25 to 30 years old, right at the point where springs, cables, and the opener's drive gear wear out together. These houses weren't given the cheapest builder-grade door either - mid-90s construction here tends toward two-car garages with taller openings, and the tracks and springs were sized for heavier sectional doors. When one of those springs lets go, the door doesn't just stop working, it often comes down unevenly because the opener keeps trying to lift a door that's lost half its lift assist. In the colder months, under this region's moderate-cold climate band, steel panels from that era without foam-core insulation also warp slightly at the seams, which throws off the roller alignment. That combination - original-era hardware past its service life, plus a panel that's started to flex - is a different failure pattern than you'd see in a house built in 1965 with side-mounted torsion hardware. It's an install-era problem, not an ancient-hardware problem.
