What We Cover
Our Seattle
Our Seattle
Deck Installation Services
Every deck installation project includes the work below, delivered by our in-house Seattle crew. No subcontractors. No surprise add-ons. Every job covered by our 10-year workmanship warranty.
Engineered Footings
Footings carry the load. We pour concrete piers 30 inches (76 cm) deep on stable soil, or install helical piles on saturated soil footing requirements common to Seattle hillsides.
Framing & Ledger Attachment
Install deck Seattle framing uses pressure-treated lumber rated for ground contact, joist tape on every member, and Simpson Strong-Tie DTT2Z connectors for ledger attachment, the strongest residential ledger system on the market.
Decking & Hidden Fasteners
We install Trex, TimberTech AZEK, Fiberon composite, Western Red Cedar, or IPE hardwood. Hidden fastening systems eliminate face-screws and create a clean board surface.
Railings & Stairs
Code-compliant 36-inch residential or 42-inch elevated railings. Options include Cable Railing for view homes, Glass Balustrades for waterfront, or composite balusters for traditional styles.
Finishing & LED Deck Lighting
Marine-grade stain or sealer (cedar/hardwood), optional LED deck lighting in risers and post caps, planter integrations, and final SDCI inspection prep.

Built for Seattle Weather.
Repaired by Seattle Experts.
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 deck installation 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
