Most of the houses we get called to sit in that 1980s-90s band of construction that makes up the bulk of Arlington's stock, with the wider service area spanning homes built anywhere from 1953 to 2014 and a median build year around 1990. That matters because a door installed in, say, 1988 has had roughly three and a half decades of Texas heat working on its torsion spring's temper and its steel track's alignment. Heat here runs moderate rather than extreme, so we don't see the flash failures you'd get somewhere with brutal summers, but we do see the slow kind: grease that's gone gummy, spring coils that have lost a fraction of their tension every summer for thirty years, and hinges that have worked loose from expansion and contraction cycling year after year. In the 22 named areas across this service territory, the age of the door usually tracks pretty closely with the age of the house, since most original doors on 1980s and 90s builds never got swapped out. When a spring finally lets go, it's rarely a surprise to us. It's a door running on original 1990s-era hardware that finally reached the end of its duty cycle, not a fluke.
