Most houses here went up between 1938 and 1995, with the median right around 1972, so a lot of garage doors are still riding on hardware from the Nixon administration. With 56,194 owner-occupied houses across this service area, a huge share of them built in that same 1960s-70s wave, off-track complaints follow the same pattern street after street: a track bracket bolted into framing lumber that's shrunk and loosened over fifty-plus years, rollers that were never upgraded from the original steel to sealed nylon, and a rail that's taken one too many knocks.
York sits in a cold-climate band that sees genuine freeze-thaw cycles each winter, and that swing is what loosens the track brackets on older doors. Wood framing expands and contracts with moisture and temperature, and every cycle backs the lag screws out a fraction more until the track has enough play to let a roller jump the rail on a hard stop or a gust of wind against the door face.
