Classic Looks. Real Wood. Built Right.

Wood Deck Building in Washington

Traditional Decks with Timeless Appeal

We Build Custom Cedar and Pressure-Treated Decks

Natural wood never goes out of style. Cedar brings warmth, grain, and beauty. Pressure-treated lumber delivers rugged strength at an affordable price. At Alliance Deck Builders, we help Washington homeowners get the look and feel they love — with expert framing, safe footings, and durable finishes that protect against rot, insects, and wet weather.

Choose the Right Wood for Your Deck

Cedar for Looks. Pressure-Treated for Strength.

Not sure which type of wood fits your needs? Cedar is lightweight, rich in color, and naturally rot-resistant. It’s perfect for clean, upscale decks that feel great underfoot. Pressure-treated wood is more budget-friendly and made to resist decay and insects through chemical treatment. We’ll guide you through your options — both look great when built right.

From Backyard Patios to Wraparound Porches

Wood Decks That Match Your Home and Layout

Whether you’re adding a small patio-style deck or a full wraparound porch, we frame, build, and finish each project to fit your property. That means custom sizing, proper slope handling, and matched finishes that complement your siding, trim, or railings. We work with both modern and historic homes throughout Washington.

Our Build Quality Sets Us Apart

We Don’t Cut Corners — Just Boards

Every board is measured, cut, and fastened by skilled local carpenters — not subcontracted out. We pre-treat cut ends, seal joints, and use galvanized screws to protect against moisture. Our railings meet code. Our stairs are safe. And we never leave behind warped boards or rough edges. It’s the kind of build your neighbors notice.

Washington Weather? We Build for It.

Framing, Drainage, and Sealing That Last

Wood decks in Washington need more than good looks. They need smart framing and finishing to survive rain, snow, and sun. We use pressure-treated framing, moisture barriers, and optional under-deck drainage to protect your investment. Every board is sealed and spaced for airflow — because it’s not just about how your deck looks today, it’s how it lasts tomorrow.
