Across the Mansfield service area, most of the housing stock went up between 1938 and 1983, with a lot of it clustered around 1957, and across the sixteen communities we cover, pre-1960 construction is the norm, not the exception. Garage doors and track hardware from that era, or replacement doors hung on original jamb framing from that era, weren't built to today's spec. Tracks were often lighter gauge, brackets were fewer and more lightly fastened, and decades of settling in a house built before 1960 means the opening itself is rarely still perfectly square. Add a cold-climate winter to that and you get metal that contracts, mounting screws that back out of old wood jambs, and tracks that were already a little off going into the season and get worse when the frost sets in. A door that's been living with a slightly bent track for years can ride fine for a long stretch, then jump the roller the first hard-freeze morning when everything's stiff. That combination - old bracket work plus a severe cold band - is why this fault shows up so often on service calls across the area rather than as a rare fluke.
