Life Outdoors, Elevated: Deck & Porch Contractors

At Capitol Custom Construction, we know that your life isn’t contained to the inside of your house. That’s why we take pride in building and finishing beautiful decks and porches made to last through harsh PNW weather.

A clean, sturdy, and expertly built deck or porch is the perfect way to beautify your house, increase property value, and increase your family’s enjoyment of your outdoor spaces. See our featured Coastal Vacation House Decking Project and our Tumwater Deck & Porch Builder Guide.

From Consultation to Fully Built Decks and Porches: We handle the hard parts of deck and porch construction for you—deep footings for wet Western Washington soils, ledger board flashing, structural framing, composite or wood decking, and covered porch roofs.
Expert Guidance and Advice: We walk you through material tradeoffs (WOLF/Trex composite vs. cedar vs. pressure-treated lumber) and handle all local permitting and sloped-lot engineering.

Built for Pacific Northwest Weather

Precision Ledger Flashing & Footings: Preventing water intrusion at the house connection and sizing footings to your lot’s true soil bearing capacity.
Composite, Cedar & Aluminum Railings: High-durability materials including WOLF composite decking, Fortress aluminum picket railings, and corrosion-resistant fasteners.
Covered Porches & Structural Additions: Integrated roof structures tied seamlessly into your existing roofing and siding.
