Two Arlingtons, Two Window Problems
Arlington is really two housing stories sharing one zip code. Around historic Olympic Avenue and the older blocks near the Stillaguamish, homes from the 1900s through the 1940s still carry wood sashes and, in some cases, original wavy glass. Out toward Smokey Point and the newer plats, production homes from the 1990s onward came with builder-grade vinyl that is now reaching the age where insulated-glass seals fail wholesale. Both kinds of houses call us about windows; the right answer for each is completely different, and treating them the same is how window mills do damage.
The valley setting raises the stakes. Cold air pools along the Stillaguamish on winter nights and fog hangs in the river bottom through many mornings, so single-pane and failed double-pane glass in Arlington runs wet with condensation for months. Add wind funneling down the Highway 530 corridor, and leaky openings make themselves felt in every heating bill.
