Sunnyvale properties with composite decks, concrete driveways, and front walkways deal with the same organic buildup as the rest of the Bay Area — but composite decking needs a different approach than standard concrete surfaces. High-pressure washing damages composite decking texture and can void manufacturer warranties. We use soft wash technique on composite, and standard pressure wash on concrete and pavers.
Composite decks in Sunnyvale develop dark staining from algae, mold, and mildew — particularly on shaded sides and north-facing surfaces. We apply low-pressure soft wash with appropriate cleaning solution to lift organic buildup without damaging the surface. The deck is rinsed thoroughly to clear residue and prevent streaking.
Concrete walkways and driveways are cleaned at standard pressure — systematic passes, pre-treatment for oil and organic staining, detail work on edges and curbs. Properties with connected composite deck and concrete surfaces get both cleaned in the same visit.
