The Pacific Northwest subjects outdoor structures to conditions that few other regions in the country replicate. Kent, WA receives an average of 150 rain days per year. Surface moisture on horizontal structures like decks never fully dries between fall and spring. UV exposure during summer months then causes rapid oxidation in unprotected wood fibers. The result is a freeze-thaw and wet-dry cycle that accelerates material degradation faster than in drier climates.
Choosing the right surface for a deck here is not a style preference. It is a structural decision. The wrong material requires replacement in under a decade. The right one, installed correctly by a knowledgeable deck company in Kent, WA, performs for 25 to 50 years. SmartDecks builds with composite and wood options matched to each homeowner’s site conditions, sun exposure, and long-term maintenance preference.
Why the Pacific Northwest Climate Eliminates Some Material Options Entirely
Not all decking products sold nationally are appropriate for western Washington. Several fail predictably in the region’s specific conditions.
Tropical hardwoods like ipe and cumaru perform well in humid climates with consistent moisture. However, they require annual oiling to prevent surface checking and gray discoloration. In Kent’s climate, where rain and UV alternate seasonally, skipping even one maintenance cycle causes surface cracks that allow water to penetrate the board’s interior. Once moisture reaches the core, the checking accelerates into splitting…
