Cascadia Deck & Fence of Seattle

Composite decks · wood decks · fences — Seattle & King County

Built for the long wet months, and the bright ones that make them worth it.

We design and build composite decks, wood decks and fences for Seattle homes — outdoor rooms that shrug off drizzle, moss and grey winters, then look their best when the long evenings of July finally arrive.

01 — Services

What we build, board by board.

Composite decking is the centre of our work. Around it sit the wood decks, repairs, railings, fences and gates that finish a yard.

  • 01

    Composite decks

    Capped boards over framing planned for a wet climate: the deck most Seattle homeowners ask us about, and the one we’d choose for a shaded, rainy lot.

    Wood decks

    Cedar and pressure-treated lumber still have their place, especially for smaller budgets or anyone who loves real grain and doesn’t mind a brush and a can of stain.

    Repair, resurfacing & railings

    Soft boards, wobbly stairs, a railing that no longer feels trustworthy. Often the bones are fine and only the skin needs replacing.

    Wood & cedar fences

    Privacy screens, horizontal slats, good-neighbor panels and pickets, with posts set for ground that stays damp from October to May.

    Metal fences & gates

    Chain link, ornamental steel, aluminum and wood-and-metal hybrids, plus gates hung to close cleanly for years.

02 — Why composite here

A material that suits the weather we actually have.

Western Washington is kind to moss and hard on untreated wood. Composite simply takes the damp less personally.

Rain

A protective cap keeps water on the surface instead of in the board, so there’s far less swelling, cupping or rot at the ends.

Moss & mildew

On composite, growth rinses off with soap and a soft brush; on bare wood it tends to work its way in.

Bright summers

Capped boards are made to resist fading and staining, so the colour you choose in spring still reads true after August.

Your weekends

No annual sealing or sanding. A gentle wash in spring and fall is usually the whole routine.

Looking after it

Even the most forgiving deck appreciates a little attention through a Seattle winter. Our deck care guide for the Seattle climate covers moss, algae, leaves and standing water, season by season.

04 — Where we work

Seattle, and the rest of King County.

We work from Interbay, between Queen Anne and Magnolia, and travel throughout the city and county.

Styles worth stealing.

06 — Before you get in touch

A few first questions.

Do you only build composite decks?

Composite is our focus, but we also build cedar and pressure-treated decks, repair older decks, and put up wood and metal fences and gates. We’ll recommend whatever fits your yard best.

How early should I get in touch for a summer deck?

Winter and early spring are ideal. That leaves time for design, any permit questions and scheduling before the dry months fill up.

Do I need to know exactly what I want?

Not at all. A rough idea of size and use is plenty. Working out the details is what the site visit is for.

Tell us about the space.

A few lines are enough to begin. We’ll reply to arrange a free visit and a written estimate.
