Deck & Patio Cleaning in Sammamish, pressure matched to the board

Sammamish Plateau decks sit under tall evergreens, so needles, shade and damp turn big elevated decks green and slick faster than you'd expect.

Why Sammamish

What to know about deck & patio cleaning in Sammamish

In Klahanie, Trossachs, Pine Lake and Sahalee, large deck footprints and heavy canopy mean a lot of board surface in permanent shade. We identify the material, test a spot, apply a wood-safe cleaner for lumber or a gentle detergent for composite, and clean with the grain. Railings, spindles and stairs are detailed, and wood gets a brightener that restores tone.

Sammamish FAQ

Deck & Patio Cleaning questions, answered

Why does my shaded Sammamish deck turn slick so quickly?

Shade and needle litter keep boards damp, and algae thrives in that. Cleaning removes the film, and keeping needles swept and branches trimmed back slows its return. Many plateau owners schedule a yearly clean for exactly that reason.
