4 materials work well in Leschi, each with real trade-offs. Trex Transcend and TimberTech AZEK (PVC composite) handle Seattle moisture with 25-30 year fade warranties and no annual maintenance, but composite gets hot on south-facing decks in summer. Western Red Cedar costs less upfront and looks great on traditional Leschi homes, though you'll re-stain it every 2-3 years.
