About Our Trex Decking Services
A. Sanders Construction builds stunning Trex composite decks for homeowners in Maple Valley, Renton, Kent, Covington, and Issaquah. Trex decking is the #1 composite decking brand in the world, offering the beauty of real wood without the constant maintenance. Unlike traditional wood decks that require annual staining, sealing, and eventual replacement, Trex decking resists fading, staining, scratching, and mold for decades with minimal upkeep. Our deck construction services include complete new deck builds, old deck replacements, deck expansions, pergola additions, and railing systems. We work with the full Trex product line including Trex Transcend, Trex Select, and Trex Enhance collections. Every deck we build features proper structural framing, adequate footings, and code-compliant railings. In the Pacific Northwest climate, Trex's moisture-resistant composite materials are the smart choice for outdoor living spaces that perform year-round.

How much does a Trex deck cost?
Trex decks typically cost $30-$60 per square foot installed in King County, depending on the product line, deck complexity, railing choices, and site preparation. A 300 sq ft deck might range from $12,000 to $20,000. We provide free detailed estimates.
How long does Trex decking last?
Trex decking comes with a 25-year limited residential warranty against structural damage, and a 25-year limited warranty against fading and staining. With proper care, Trex decks can last 30+ years.
Is Trex decking slippery when wet?
Trex decking is designed with slip-resistant surfaces. While any outdoor surface can be slippery when wet, Trex's textured grain pattern provides good traction even in the rainy Pacific Northwest.
