TimberTech AZEK & Pro Lines
TimberTech Pro certified install of AZEK PVC, Premier PVC, and TimberTech composite lines. AZEK works best on waterfront and rooftop. Composite Pro lines suit mid-range budgets.

Composite deck contractor Seattle installations for Fiberon Concordia, Fiberon Paramount PVC, and Azek Vintage Collection. Each brand has specific fastening systems we stock in-house.
Hidden Fastening Systems

Seattle decks face conditions most contractors don't understand. Our 37+ inches of annual rainfall combined with evergreen shade creates the perfect environment for wood rot. Add freeze-thaw cycles, salt air from Puget Sound, and moss-friendly surfaces, and you have a deck that's aging faster than almost anywhere else in the country.
We've worked decks in every Seattle microclimate, from shaded north-facing lots in Fremont and Ravenna, to salt-exposed waterfront homes in Magnolia and Alki, to hillside elevated decks in Queen Anne and Capitol Hill. Each has unique failure patterns. We know them.
That's why every composite deck builder project we deliver uses stainless or coated fasteners (not basic galvanized), proper joist flashing, and pressure-treated framing rated for ground contact, even where code doesn't require it.
- Stainless / coated fasteners standard on every project
- Ground-contact-rated framing exceeds Seattle code requirements
- Joist flashing & ledger protection against PNW moisture
- Marine-grade sealers for waterfront & salt-exposed homes
