Why Renton Homeowners Choose Composite Decking

Composite decking combines wood fiber and recycled plastic into a board that looks like real wood, holds up to Pacific Northwest rain without rotting, and requires only an annual hose-down. Trex, TimberTech, and Fiberon are the three brands we install — each with different performance profiles for Seattle's microclimate.

Kennydale waterfront properties near Gene Coulon Park specify cable railing with composite decking for unobstructed Lake Washington views. The Highlands and Tiffany Park neighborhoods are in the PT deck replacement wave — most 1980s-2000s homes in these areas have aging wood decks ready for composite upgrade.

Seattle's 38 inches of annual rain plus summer UV creates a demanding test environment for decking. Composite outperforms cedar in this climate on every metric except first cost — after year 3, composite is the less expensive material on a per-year basis once you factor in cedar's staining, sealing, and replacement costs.
