Cedar vs Composite: A Deep Dive into Deck Materials for PNW Homes
If you live in the Pacific Northwest, you know that the elements aren’t exactly gentle. Rain, moss, fluctuating temperatures, and damp shade mean any outdoor project—especially decking—has to stand up to the test of time. When it comes to choosing between cedar and composite decking, homeowners often ask: which one holds up better in our unique climate?
I’m breaking it all down—cost, upkeep, curb appeal, and resale value—so you can make the smartest choice for your outdoor space.
🌲 Cedar Decking: The Natural Beauty
Cedar is a classic for a reason. Its warm color, natural scent, and rustic texture make it a favorite for homeowners who love organic, woodsy charm.
✅ Pros of Cedar Decking:
Naturally resistant to rot and insects – especially Western Red Cedar, which thrives here in the PNW.
Cooler underfoot in summer heat.
Easily repairable – individual boards can be swapped without issue.
Visually timeless – complements craftsman, cabin, or traditional home styles beautifully.
❌ Cons of Cedar Decking:
Requires annual maintenance – sealing or staining to prevent graying and weather damage.
Prone to splintering and warping over time, especially with poor drainage or heavy rainfall.
Shorter lifespan than composite—often 15–20 years with care.
🔩 Composite Decking: The Low-Maintenance Workhorse
Composite decking is made from recycled plastic and wood fibers, designed to mimic wood without the upkeep.
✅ Pros of Composite Decking:
Extremely low maintenance – no staining or sealing required.
Longer lifespan – typically 25–30+ years with little upkeep.
More resistant to mold and mildew—a big bonus in our damp climate.
Uniform appearance – available in many colors and faux wood grains.
❌ Cons of Composite Decking:
More expensive upfront – often $10–$15 per square foot vs. cedar’s $3–$7.
Can get hotter underfoot on sunny days.
Not easily repairable – a damaged board usually means special ordering and replacing full sections.
🏡 What’s Best for Resale Value in the PNW?
In markets like Maple Valley, Issaquah, and Renton—where outdoor living is a major selling point—buyers tend to appreciate low-maintenance features. Composite decks can be a strong draw, especially for busy families or buyers with second homes. However, a beautifully maintained cedar deck can be equally appealing in older, more character-rich homes.
Ask yourself:
Is this your forever deck, or are you prepping to sell within 5 years?
Do you enjoy home maintenance projects, or prefer a set-it-and-forget-it approach?
Do you want your deck to blend with surrounding trees and landscape, or look polished and modern?
🧰 Local Pro Tip:
If you choose cedar, make sure your builder leaves at least a ⅛” gap between boards and uses stainless steel screws to avoid discoloration. For composite, choose a textured, non-slip finish, especially if your deck gets a lot of shade.
💬 Final Thoughts
There’s no one-size-fits-all answer, but there is a best fit for your home. Whether you go with cedar’s warmth or composite’s durability, a well-planned deck adds major value to your PNW lifestyle—and your real estate portfolio.
