Membrane Decking in Kirkland

Why Kirkland Homeowners Choose Membrane Decking

Vinyl membrane decking (Duradek, Tufdek, Duralast) creates a fully waterproof walking surface for decks built over garages, basements, or living spaces below. Unlike composite or cedar, membrane forms a continuous water barrier — critical in Seattle's 38-inch annual rainfall when the space beneath the deck must stay dry.

Kirkland Specifically

Multi-story Kirkland builds near the waterfront often have decks over garages or lower living levels. Membrane provides the waterproof barrier that conventional composite gaps cannot achieve over occupied space.

Seattle rain falls at an angle. A 1/4-inch board gap in a composite deck channels water directly onto the structure below — fine if there's nothing down there, catastrophic over a living room or garage. Membrane decking eliminates this variable with a continuous 60-mil vinyl surface that drains to the edge, keeping the space below fully protected year-round.
