Deck & Patio Cleaning in Issaquah, pressure matched to the board
Issaquah's cool, wet foothills keep decks and patios slick for much of the year, and clearing that film is a safety job as much as a cosmetic one.
What to know about deck & patio cleaning in Issaquah
In the Highlands, Talus and up around Squak and Cougar Mountain, shaded decks, north-side patios and stone steps rarely dry out. Algae and moss take hold on boards and flagstone alike. We test and identify the surface, clean wood at low pressure and composite with detergent, and treat flagstone and concrete patios with the right pressure and a post-treatment so regrowth is slower.
Foothill homes with steep roofs and shaded hardscapes, plus newer Highlands and Talus builds. About 40 minutes from our Lake Stevens shop.
