Fort Washington's housing runs right in the middle of this region's broader build window - the service area overall spans 1962 to 2007 with a median around 1982, and Fort Washington's own stock centers on 1980, squarely in the thick of it. That means a lot of original steel doors are now 40-plus years old, and the failure pattern is consistent: galvanized panels that have gone soft at the bottom section from decades of ground moisture, extension springs stretched past spec, and hinges worn oval instead of round.
The cold-climate severity rating for this part of Maryland is also part of the story. Steel contracts hard in a deep cold snap, and a panel that's already thinned by corrosion is the one that splits along a seam instead of just creaking. Homes built in this window weren't speced with insulated doors as standard, so uninsulated panels have taken the full brunt of 40-plus winters with nothing buffering the swing.
