This isn't a defect, it's math. A door installed in 1985 is now close to forty years old, and steel garage doors of that era were built to a lower standard than what's code and common practice today - thinner gauge panels, minimal or no insulation, and weatherstripping that was never designed to last five decades of our severe cold winters. Farmington's winters put real stress on an old door: the steel contracts, old seals crack and shrink, and a gap that was invisible in July becomes a cold draft straight into the garage by December. Because most of the area's roughly 2,935 owner-occupied houses share that same 1980s-to-early-90s build era, this is less an isolated problem than a wave - a lot of doors in this town are aging out at close to the same time, for the same reason. It's not that one house got unlucky with a bad door. It's that an entire generation of garage doors installed across Farmington's neighborhoods during that building boom is now reaching the point where insulation, seals, and steel gauge all matter more than they did when the door went in.
