Cedar vs. Composite vs. Trex Decking in Seattle: Complete Comparison

Cedar is the traditional choice for Pacific Northwest decks — and still a great one for the right homeowner. Cedar pros: • Natural wood look and feel that composites still can't fully replicate • Lower upfront cost than composite • Can be sanded and refinished if damaged • Environmentally friendly (sustainably sourced locally) • Takes stain beautifully — huge color range Cedar cons: • Requires staining or sealing every 2–3 years in Seattle's climate • Will gray and silver quickly if left untreated (not necessarily bad, but different) • Susceptible to rot at post bases and board ends if clearance isn't maintained • Moss and mildew growth between boards if not properly maintained • Individual boards need replacement as they rot or crack over time Best for: Homeowners who enjoy DIY maintenance, want natural wood aesthetics, and have a tighter initial budget.

Composite decking has evolved dramatically over the past decade. Today's premium composites are beautiful, durable, and genuinely maintenance-free. Composite pros: • Zero annual maintenance — no staining, sealing, or sanding • Won't rot, warp, crack, or splinter in Seattle's rain • 25–30 year fade and stain warranty from leading brands • Slip-resistant textured surface — safer in Seattle's wet conditions • No moss or mildew penetration • Consistent color that doesn't gray out Composite cons: • Higher upfront cost than cedar • Can feel slightly different underfoot (less "springy" than wood) • Scratches are harder to repair than wood (sanding doesn't work the same way) • Some entry composites get warm in direct sun Best for: Homeowners who want zero maintenance, plan to stay 10+ years, and want maximum warranty protection.

After 12 years building decks in Seattle, here's our honest assessment: If you're staying in your home 10+ years: Composite wins. The zero-maintenance benefit is significant in Seattle's climate, and the 20-year cost is typically lower. If you love natural wood and don't mind maintenance: Cedar is excellent. Western red cedar is beautiful and naturally rot-resistant — just commit to the maintenance schedule. If budget is the priority: Start with a cedar frame and entry composite boards — you get the longevity of composite decking with a lower frame cost. If resale is a priority: Premium composite (Trex Transcend, TimberTech) has better perceived value to buyers in Seattle's competitive real estate market.
