Composite decking has become the go-to choice for homeowners looking for beauty without the upkeep. At King County Decks, we specialize in installing composite decks that offer the warmth of wood with the strength and durability of modern materials — built to last through every season in the Pacific Northwest.
Whether you’re designing a cozy family barbecue patio or a custom three-story deck with stairs, pergolas, pools, and jacuzzi integration, our team brings 23 years of experience and a reputation for craftsmanship to every project. Homeowners across Bellevue, Seattle, Tacoma, Kirkland, Redmond, and Mercer Island choose us for composite deck solutions that are low-maintenance, high-performance, and tailored to fit.
Why Choose Composite Decking?
Composite decks resist moisture, fading, warping, and insects — making them ideal for the wet winters and dry summers of Western Washington. With a wide variety of textures, colors, and finishes, composite options can mimic natural wood while offering a sleek, modern or traditional look.
We offer a full selection of materials, from budget-friendly brands to premium lines with capped finishes and hidden fasteners. You can also pair your composite deck with:
-
Matching railing systems (wood, aluminum, or composite)
-
Custom stairs and landings
-
Overhead pergolas or shade structures
-
Integrated lighting and privacy screens
Flawless Installation. Custom Design.
We don’t believe in one-size-fits-all construction. Every deck we install is carefully designed around your home, landscape, and goals. Whether your backyard is flat, sloped, or multi-tiered, we can create a composite structure that blends into its surroundings and elevates your lifestyle.
From standard layouts to complex, multi-level systems with custom railing and stair access — we handle the engineering, permitting, and construction start to finish.
