The region this town sits in has housing mostly built between 1938 and 1992, median around 1959, and Western Springs itself runs close to that at 1960. Garages from that era were framed for narrower single doors or older double-door track hardware, and over sixty years of freeze-thaw cycles in a cold, moderate climate band, the wood framing around the track brackets shifts. A quarter-inch of movement in the jamb is enough to pull a track bracket loose, and a loose bracket is the number-one reason a door walks off its rollers here rather than in newer construction.
With a median household income above $200,000 in this town, a lot of these garages have been updated - new opener, sometimes a new door face - but the track and the framing behind it often haven't been touched since the house was built. That mismatch, new door hardware bolted to a sixty-year-old bracket, is exactly the setup that fails at the track, not at the spring or the opener.
