Seattle’s climate creates unique cleaning challenges. The near-constant overcast and moisture means algae and moss grow on every north-facing and shaded exterior surface. Most Seattle homes — especially in Capitol Hill, Queen Anne, Bellevue, and Kirkland — show green discoloration on siding within 1–2 years without treatment.
We use soft wash chemistry specifically formulated for Pacific Northwest growth. Safe for cedar, painted wood, fiber cement, stucco, and all siding types common to Seattle architecture.
