Most of the housing stock across Vancouver's service area went up between 1977 and 2011, with the median build year sitting around 1994 and a heavy concentration in the 1980s and 90s across the 22 named areas we work in - Hazel Dell, Orchards, Salmon Creek, Felida, and the rest. That matters because a garage door system has a shelf life, and a lot of this city's doors, springs, and openers are now thirty to forty years into that life at the same time.
Torsion springs from that build era are rated for a set number of cycles, usually somewhere around 10,000, and a door that opens four times a day has been doing that math since before most of these houses had their first re-roof. The openers are often original or a first replacement, chain-drive units with gears that strip and logic boards that corrode once they hit the end of their run.
Add the climate: this area sits in a mild band but still sees real freeze snaps most winters. Grease that's thickened from age gets worse when the temperature drops, which is exactly when a tired spring or a weak opener finally gives out. We see the same pattern house after house - it's not bad luck, it's the age of the stock matched against a few cold mornings.
