Late-1980s and 1990s homes
Most of the houses we get called to were built between 1989 and 1997, and that holds true across the five main pockets of town where the stock runs mostly 1980s and 90s construction. That matters because a door from that build era has specific hardware: steel panels on standard-lift torsion springs, openers that are well past their design life even if they still run most days.
