1979 late-1970s-1990s vintage
The houses here run to a median build year of 1979, right inside the 1961-2010 stock we see across the region, so the doors and openers are usually late-70s to 90s vintage - steel sectional panels, torsion springs sized for that era's door weight, and chain-drive openers that are now old enough to be on their second or third circuit board.
