This area sits in a cold-moderate climate band, not the harshest winter zone in the state but enough that grease stiffens, metal contracts, and a spring already near the end of its life gets pushed past it on a hard freeze. That's a different failure pattern than a mild-climate suburb sees - the same worn spring might hold another year somewhere warmer.
Combine that with the build era and you get a specific, repeatable fault: original torsion hardware, cold-stressed, on a door that's outlived at least one homeowner's assumption that "it's always worked fine." We see this pattern across the 1980s-era stock in this part of the service area, and Fairwood's numbers put it squarely in that window.
We don't run a branch in Fairwood - we come from Tukwila, about six miles out, for every call here. That distance doesn't change the diagnosis, but it does mean we're not doing same-day walk-ins off a storefront; every job here starts with a call.
