Cedar & Wood Deck Builders in Portland
Natural beauty, warmth, and character — pressure-treated and cedar decking built to handle Portland’s climate.
Why Portland Homeowners Still Choose Wood
Composite decking has come a long way, and we install plenty of it. But when clients walk across a freshly oiled western red cedar deck on a warm August evening, barefoot and holding a glass of wine, nobody asks why we still build with wood. The answer is underfoot.
Wood delivers something engineered materials cannot replicate: genuine warmth, a living grain pattern that changes subtly over the years, and a feel against bare skin that stays comfortable from cool May mornings through the hottest days of summer. Whether your home is a 1920s Craftsman in Sellwood, a mid-century ranch in Lake Oswego, or a contemporary build in the West Hills, wood decking integrates with the surrounding landscape in a way that composites struggle to match.
We are transparent about the trade-offs. Wood requires maintenance that composite does not. It has a shorter structural lifespan in our wet climate than it would in Phoenix or Denver. But for homeowners who value authenticity and are willing to invest a few hours of care each year, a well-built wood deck remains one of the most rewarding additions you can make to a Portland home.

Wood Species Guide: Choosing the Right Lumber
Selecting the right species is the single most important decision you will make before construction begins. Each option brings distinct advantages and limitations.
Western Red Cedar
Cedar is the default choice for the Pacific Northwest. It contains natural oils that resist decay and insect damage without chemical treatment, resists warping better than most softwoods, and takes stain beautifully.
However, there is a critical distinction most contractors avoid: new-growth cedar is not the same product as the old-growth cedar your parents’ deck was built from. Today’s cedar comes from younger, faster-growing trees with wider growth rings and less dense heartwood. It is softer, more porous, and less naturally rot-resistant than the old-growth boards that gave cedar its legendary reputation.
We offer two grades: Standard Cedar (Tight Knot), the workhorse grade for most residential decks, and Premium Clear Cedar, virtually knot-free with tighter grain and better longevity, costing roughly 30-40% more.
Pressure-Treated Pine
Pressure-treated lumber is southern yellow pine infused with copper-based preservatives under high pressure. It is the most affordable option with excellent structural strength, and its chemical treatment provides genuine rot resistance that often outperforms untreated cedar in ground-contact applications.
The downsides: PT pine is heavier, more prone to warping as it dries, and has a greenish tint most homeowners cover with stain. We typically recommend PT for substructure framing rather than decking boards, though it remains a solid choice for budget-conscious projects.
Redwood
Redwood is the premium natural decking material with superior decay resistance, striking color, and remarkable stability. The challenge in Portland is availability and cost — premium heartwood redwood can cost 50-80% more than comparable cedar with multi-week lead times. We source it for clients who want the absolute best, but always present cedar as the more practical alternative.

Portland Climate Reality Check
We love building wood decks and we want you to love owning one. That means being honest about what Portland’s climate does to natural wood.
The Rain. Portland averages 43 inches of rain per year, with nearly continuous moisture exposure from October through April. Wood absorbs water, swells, then contracts when the sun returns. This wet-dry cycle causes checking, cupping, and eventual decay. A deck here works harder in one winter than a deck in Boise works in three.
Moss and Mildew. Our mild, wet winters create ideal conditions for biological growth that traps moisture against the surface, accelerates decay, and creates a slippery film. Annual cleaning is not optional — it is basic safety maintenance.
Gray Weathering. Left untreated, all wood species weather to silvery gray within 6 to 18 months. If you want to maintain warm, rich tones, you must commit to regular staining. There is no middle ground.
New-Growth Cedar Expectations. The cedar available today is not the same wood your neighbor’s 30-year-old deck was built from. New-growth cedar decking boards, properly maintained, typically last 10 to 15 years before needing replacement. The substructure lasts 20+ years because it is protected from direct UV and weather. This does not mean cedar is a bad choice — it means you should plan for board replacement rather than expecting one installation to last three decades. We design substructures with this in mind.
Cost Guide: What to Budget
Pricing varies based on species, size, complexity, site conditions, and railing choices. Realistic ranges for 2026:
- Pressure-Treated Pine: $25 – $40 per square foot installed
- Western Red Cedar (standard): $30 – $45 per square foot
- Western Red Cedar (premium clear): $40 – $50 per square foot
- Redwood (construction heart): $45 – $65 per square foot
These include materials, labor, standard railing, a single staircase, footings, and permit fees. Most Portland wood deck projects fall between $15,000 and $25,000 for a 300-to-400-square-foot deck. Larger or more complex builds can run $30,000 to $50,000+.
The 20-Year Maintenance Cost Nobody Mentions
Over 20 years, a cedar deck costs approximately $16,000 to $22,000 more in maintenance than a comparable composite deck:
- Annual cleaning: $200 – $400/year professional, or 4-6 hours DIY
- Staining: $800 – $1,500 every 1-3 years on a 350 sq ft deck
- Board replacement: $3,000 – $6,000 at the 10-to-15-year mark
- Hardware inspection/replacement: $300 – $800 over 20 years
A composite deck requires only periodic cleaning. We always present both options with full lifecycle numbers so your decision is informed.
Cedar vs. Composite: An Honest Comparison
We build both and genuinely do not have a horse in this race. Our job is to build whatever you choose to the highest standard.
Choose wood if: You prioritize natural beauty and warmth underfoot. You are willing to invest in annual maintenance. You prefer lower upfront cost. You want a material that can be sanded, refinished, and renewed.
Choose composite if: You want minimal maintenance and maximum longevity. You prefer predictable long-term costs. You plan to stay 15+ years. You never want to stain or seal again.
The numbers: A cedar deck that costs $18,000 to build may reach $34,000-$40,000 over two decades with maintenance. A composite deck that costs $24,000 to build stays around $26,000-$28,000 over the same period. Neither answer is wrong — we just want you to decide with clear eyes.
How We Build Wood Decks to Last
Construction quality determines whether your deck lasts 8 years or 18. These practices exceed minimum code requirements.
Hot-Dipped Galvanized Fasteners. Oregon Residential Specialty Code requires corrosion-resistant fasteners for exterior wood. We use hot-dipped galvanized (HDG) or stainless steel screws, joist hangers, and post bases on every project. Electro-galvanized fasteners do not meet code and will corrode within years in Portland’s climate.
Proper Ventilation. Trapped moisture underneath is the top cause of premature decay. We maintain minimum 18-inch ground clearance (24 preferred), ensure cross-ventilation, and install landscape fabric to suppress weeds and reduce ground moisture.
Immediate Sealing. New cedar and redwood should be sealed within 2-4 weeks of installation. Leaving fresh wood unprotected through one Portland winter causes moisture damage that no later staining will fully correct.
Structural Over-Engineering. We build substructures to outlast the decking: 2×10 or 2×12 joists at 16-inch centers, double rim joists, through-bolted ledger connections with proper flashing, and sized concrete footings. When boards need replacing in 12-15 years, the frame should support another generation without modification.
End-Grain Sealing. Every cut end gets wax-based sealer before installation. End grain absorbs moisture at 10-12x the rate of face grain. This simple step is one of the most effective — and most commonly skipped — measures for extending board life.

Frequently Asked Questions
With consistent maintenance — annual cleaning and staining every 1 to 3 years — modern new-growth cedar decking boards typically last 10 to 15 years before needing replacement. The substructure lasts 20 to 25+ years. We design our frames to support future re-decking so you are not rebuilding from scratch.
Plan on staining every 1 to 3 years depending on product and sun exposure. South- and west-facing decks may need annual attention. We recommend penetrating oil-based stain over film-forming products — penetrating stains wear gradually and can be recoated without stripping.
Wood is susceptible to slipperiness because moss and algae colonize the surface during wet months. The biological film, not the wood itself, creates the hazard. Annual spring cleaning removes this growth. For stair treads, we can apply anti-slip strips or use grooved decking profiles that channel water away.
Yes. Modern PT lumber uses micronized copper azole (MCA) or alkaline copper quaternary (ACQ), which replaced the older CCA formulation phased out in 2004. These are EPA-registered and approved for residential decks, playgrounds, and garden beds. The copper-based compounds are tightly bound within wood fibers and safe for bare skin contact.
Absolutely. Many homeowners prefer the weathered silver-gray patina. There is no structural issue with skipping stain as long as you continue annual cleaning. Understand that unfinished wood weathers unevenly with more surface checking over time. If you go gray, commit fully — alternating between staining and skipping creates a blotchy appearance.
Late spring through early fall — May through September. This gives dry weather for construction and time to seal the wood before fall rains. We avoid November through March builds because wet lumber and inability to properly seal compromise the finished product. Reach out in February or March to get on our schedule.
A cedar deck costs 15-25% less to build — roughly $18,000 vs $24,000 for a 350-square-foot deck. But over 20 years, cedar’s total ownership cost reaches $34,000-$40,000 (staining, cleaning, board replacement), while composite stays at $26,000-$28,000. Wood wins on upfront cost and natural feel. Composite wins on lifetime value.
