Built for Portland Weather.
Repaired by Portland Experts.
Portland decks face conditions most contractors don't understand. Our 36+ inches of annual rainfall combined with evergreen shade creates the perfect environment for wood rot. Add freeze-thaw cycles, constant humidity rolling off the Willamette, 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 Portland microclimate, from shaded north-facing lots in Sellwood-Moreland and Grant Park, to river-exposed waterfront homes in Alameda and Cathedral Park, to hillside elevated decks in Southwest Hills and Hawthorne. 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 Portland code requirements
- Joist flashing & ledger protection against PNW moisture
- Marine-grade sealers for riverfront & high-humidity homes
