A door installed in 1984 was built to a different standard than one going in today. Single-layer steel panels, no insulation core, extension springs mounted along the horizontal track rather than a torsion bar over the opening - that's what came stock on houses from that era across this part of the county. Cottage Lake's median household income runs $197,331, well above the $148,590 average across the rest of our territory, but income doesn't rebuild a door; it just means more owners here have the means to replace hardware before it fails outright, if they know it's due. The climate here is cold-moderate, which over thirty-plus winters means repeated freeze-thaw cycling on any exposed spring coil or unlubricated hinge pin. None of that is unique to any one street - it's what happens to a specific kind of door, built in a specific decade, sitting through a specific kind of winter, year after year.
