Building a deck in Washington
Climate and materials
Long wet seasons and mild temperatures mean moisture, moss and mildew are the main concerns. Drainage, slip resistance and a well-flashed ledger connection matter a lot.
- Pressure-treated wood: Affordable; regular cleaning and sealing help it handle months of rain.
- Cedar: A regional favorite for its natural rot resistance and look; plan on periodic finishing.
- Composite: Popular for low upkeep in wet climates; periodic cleaning keeps mildew off the surface.
- PVC: Excellent moisture resistance for shaded, rainy yards.
What changes the price
Factors affecting deck cost
- Size and shape
- Square footage drives framing, decking and labor. Angles and multiple levels add cutting and time.
- Height
- Elevated decks need taller posts, more bracing, railing and stairs.
- Material
- Pressure-treated wood, cedar, composite and PVC differ in up-front cost and upkeep.
- Railings and stairs
- Railing style and the number of steps can be a large share of the total.
- Site and removal
- Slope, access and tearing out an old deck all change the scope.
- Permits
- Requirements vary by municipality — confirm with your local building department or contractor.
