Signs to watch
Is this you?
You're done staining every other summer
In a climate that stays damp two-thirds of the year, wood decks live on a maintenance treadmill. Capped composite steps off it — a wash-down instead of a sand-and-stain weekend.
Moss and mildew keep coming back
Real wood grain traps moisture and farms moss in the PNW. Composite's capped shell gives moss far less to grip, so seasonal cleaning replaces annual battle.
Splinters, cupping, and gray boards
Wet-dry cycles cup and check wood decking and raise splinters where bare feet go. A capped composite surface doesn't splinter or gray the way exposed lumber does.
You're building for the long haul
If you plan to keep the house, composite's higher up-front cost buys back years of maintenance and a surface that still looks like itself a decade in.
Your options
What capped composite actually is — and what it needs
Capped composite is a wood-and-plastic core wrapped in a hard polymer shell that seals out moisture; that cap is why modern boards resist the staining, fading, and moss that plague uncapped early-generation product. It runs warmer underfoot than wood in direct summer sun, so we'll talk color and shade honestly — lighter tones stay cooler, and many lines add texture for wet-weather traction. Composite is heavier and less stiff than wood, which means tighter joist spacing and manufacturer-specified fasteners, not whatever's on the truck. And none of it matters if the structure under it fails: engineered footings below frost line, ground-contact-rated framing, and a flashed, bolted ledger — the connection behind every deck collapse you've read about.
The method
How we do it
- 01
Design, material, and shade review
We match board line, color, and texture to your yard's sun exposure — heat and traction are real in the PNW — and design the structure to carry composite's weight and span.
- 02
Foundation and frame
Footings inspected below frost line, framing in ground-contact-rated lumber at the joist spacing the boards require, and the ledger flashed and bolted like the roof detail it actually is.
- 03
Deck, rails, walkthrough
Boards set with hidden fasteners at spec, railing and lighting if specced, then a hose test on the ledger flashing before we walk the finished deck with you.
Straight numbers
What composite decks cost here
Capped composite costs more up front than wood — the boards themselves are a premium, and correct framing to carry them is part of the number. What moves it: square footage, height and access, railing style, stairs, and how much structure the design demands. What you get back is the maintenance you don't do for the next decade-plus. We price it against a cedar build honestly so you can compare the true long-run cost, not just day-one.
Where we do this work
Composite Decks: straight answers
Does composite decking really need no maintenance?
Low, not zero. You'll still wash it a couple times a year — pollen, fir needles, and moss spores land on every PNW surface — but there's no sanding, sealing, or staining. The maintenance that ends is the labor-intensive kind wood demands.
Doesn't composite get hot in the sun?
It can run warmer than wood on a south-facing deck in full July sun. Lighter colors stay noticeably cooler, and shade or a pergola solves the rest. We factor your sun exposure into the color recommendation instead of pretending heat isn't real.
Is composite worth the extra cost over cedar?
If you're keeping the house, usually yes — the PNW maintenance math on wood is brutal, and composite gives it back over the years. If budget is tight or you love the feel of real wood, cedar is a legitimate choice, and we'll price both without steering you.
Will moss grow on a composite deck?
Far less than on wood, but nothing in this climate is truly moss-proof — spores settle on anything that stays damp under tree canopy. The capped shell gives moss little to root into, so a periodic wash keeps it clear instead of letting it colonize the grain.
