Most of the houses in this part of the metro went up between 1950 and 2002, with the bulk of the stock dating to the 1960s and 70s across the 41 named areas that make up this market. That means a lot of garages still have the torsion spring and track hardware that came with the house, not a replacement. Nobody touches that spring until it breaks, and when it breaks it's usually mid-winter, with the door stuck half open and the cable already off the drum. A spring sized for a door forty or fifty years ago wasn't engineered with today's cycle counts in mind, and it wasn't engineered for a COLD climate band either - steel contracts, lubricant stiffens, and the spring that had another two winters in a mild climate snaps early here. The failure doesn't announce itself with a slow squeak. It's fine, then it's not, and the door won't move.
