Issaquah pressure washing & roof cleaning
Tucked against the Issaquah Alps, Issaquah homes have steep roofs and shaded, damp hardscapes that stay green most of the year.
Exterior cleaning in Issaquah, WA
From Issaquah Highlands down to Gilman Village and out toward Cougar and Tiger Mountain, homes sit in cool, wet, forested terrain. Roofs, north-side walkways and patios rarely get enough sun to dry out, so moss and black algae take hold and stay. Roof cleaning, deck restoration and driveway de-mossing are the usual Issaquah jobs.
Foothill homes with steep roofs and shaded hardscapes, plus newer Highlands and Talus builds. About 40 minutes from our Lake Stevens shop.

Local questions, answered
My north-facing patio is always slick and green. Can you keep it clean?
Yes — a proper cleaning plus a post-treatment slows regrowth, and many Issaquah customers put shaded hardscapes on a twice-a-year or annual plan so they never get dangerously slick again.
