Why Auburn 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.
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.
