Most of the houses this crew works on went up between 1952 and 1994, with the heaviest run of construction in the 1960s and 70s, spread across the sixteen named areas this service covers. That means a lot of original torsion hardware is now 50 to 70 years past its install date, carrying springs, rollers, and cable that were never rated for that many open-close cycles. Add a COLD severe climate band and you get a specific failure pattern: grease that was fine in a 1973 garage thickens and skips in January, steel brackets contract and loosen their lag screws, and a spring already near the end of its wind cycle loses tension faster in a cold snap than it would in a mild one. Owners in the roughly 13,974 owner-occupied houses across this service area tend to notice the same thing at the same time of year - the door that worked fine in October starts hesitating, groaning, or refusing to seat all the way in the first hard freeze. It isn't bad luck. It's the age of the hardware meeting the climate it was never lubricated for. A door with no maintenance history from a house built in this era is carrying decades of wear that a newer install simply hasn't had time to accumulate.
