The median year built across Edmonds runs around 1973 - about a decade earlier than the 1985 median for the wider area we cover. That matters more than it sounds like it should. Doors and openers installed in houses from that era were built for lighter, single-layer wood or steel panels and smaller openers. When a homeowner swaps in a heavier insulated steel door decades later without upgrading the track, springs, or opener, the hardware is carrying weight it was never sized for.
The usual failure we see in houses from this period isn't a dead spring - it's a door that technically opens but binds partway, because the original track was set for a lighter panel and narrower roller. A new install here often means replacing not just the door but the track and spring sizing to match it, which a straight swap-in of a newer door skips.
We're in a cold-moderate climate band here, not an extreme one, so this isn't about ice loads cracking panels. It's about mismatched hardware from a house built to a 1970s spec meeting a door built to a 2020s one.
