Mostly 1980s-era housing stock
Across the 31 named areas we cover, the stock runs mostly 1980s and 90s, with the broader range falling between 1966 and 2002 and a median build year of 1984. That matters more than people think. A door and opener installed when a house was built in 1987 is pushing forty years of spring cycles, and the hardware on a lot of these garages was never swapped out when the opener got replaced once or twice along the way.
