Waterproof Deck Coating

What This Service Involves

For decks over living areas, patios, or storage, a waterproof coating system is essential in our rain-soaked region. We apply multi-layer membrane systems that create a seamless, walkable barrier keeping water out of the structure beneath. These coatings resist UV, foot traffic, and the constant moisture that defines Northwest weather. Proper surface prep and slope are key, and our crews ensure water drains cleanly to prevent pooling and leaks.

Benefits

Keeps the space below your deck dry; Seamless membrane resists Northwest rain; Walkable, durable surface withstands foot traffic; UV-stable to prevent cracking and fading; Corrects pooling with proper slope detailing

Our Process

1) Inspect the substrate and confirm proper slope; 2) Prep and repair the surface for adhesion; 3) Apply base, membrane, and topcoat layers; 4) Detail drainage edges and cure the system

What Affects the Cost

Best Time of Year
