The failure we see tied to Edmonds's age isn't dramatic, it's just old. A door installed around 1973, which lines up with the median build year here, was likely fitted with a torsion spring sized to a lighter panel than what's probably been swapped in since - a heavier insulated replacement panel hung on hardware rated for something thinner. That mismatch shows up as a door that slams down the last foot of travel or an opener straining on the up-cycle, working harder than it should on every single use. Edmonds sits in the same cold-moderate climate band as the rest of the service area, so we're not dealing with the panel rust or coastal corrosion you'd get further out toward the Sound. The failure here is mechanical mismatch and age, not weather. It's the kind of thing that gets worse slowly, so by the time the door won't move at all, the cable's usually frayed too.
