DECKS
Decks and patios, built for the PNW
Cedar, composite and hardwood decks, patios, stairs and railings. Built on framing that holds up to a Pacific Northwest winter.
Licensed, bonded, and insured.
Building since 2020
Free written estimates
A deck or patio turns the yard into a place you actually use. We build custom outdoor spaces across Seattle, Bellevue, Mercer Island, and Kirkland, planned for Puget Sound living: covered where you need shelter, open where you want the light, and built for long wet seasons.
Decks are our specialty, but the space does not have to stop there. Decks, patios, stairs, and railings can be built on their own or planned together as one complete project. Looking for a catio, fire pit, pergola, or another custom build? Visit Other Projects.
What We Build
Every gate we build starts with the same priorities. The design may change, but the gate still needs to stay square, swing freely, close easily, and hold up to regular use.
Custom decks
Our specialty. Designed for your yard, your grade change and your budget, in materials chosen for the Pacific Northwest rather than a catalogue.
Patios
Extended outdoor living space for entertaining, or just somewhere to sit that is not the lawn. Often paired with a deck to work a grade change.
Stairs and railings.
Safe, code-compliant access between levels, seamlessly integrated with the deck’s design and detailing.
Catios, fire pits, pergolas and more can be found on the Other Projects page. We build them regularly, often at the same time as a deck.
Choose the Deck That Fits Your Life
MATERIALS WE OFFER
A well-built deck gives your home another place to live. The material determines its look, feel, and personality. Cedar brings warmth, composite makes ownership easy, pressure-treated wood stretches the possibilities, and Ipe delivers lasting natural beauty.
Cedar
The Northwest classic. Cedar feels warm underfoot, shows beautiful natural grain, and looks right at home beside almost any house. Keep its original color with a finish or let it age naturally to a soft silver.
Care:
Clean yearly. Refinish every two to four years to preserve the color.
Typical service life:
20 to 30 years with proper care.
Composite/PVC
Made for spending weekends on your deck instead of working on it. Composite offers consistent color, a wide range of finishes, and no need for staining or sealing.
Care:
Pressure wash once or twice a year.
Typical service life:
25 to 30 years or longer, depending on the product.
Pressure Treated
A practical way to build a spacious deck with real wood. It is strong, easy to stain, and leaves more room in the budget for stairs, railings, or a larger footprint.
Care:
Clean yearly. Apply a water-repellent finish every one to two years.
Typical service life:
10 to 20 years with proper care.
Hardwood/LPE
A premium hardwood for a deck you expect to keep. It has deep natural color, exceptional density, and excellent resistance to moisture, decay, and insects.
Care:
Clean yearly. Oil about once a year only if you want to preserve the brown color.
Typical service life:
40 years or longer when properly installed.
Built For the Weather.
Puget Sound decks spend much of the year wet.
Moisture, moss, and repeated freezing and thawing all take a toll. The surface boards matter, but the framing underneath carries the load and has far more to do with how long the deck lasts.
We give the structure you cannot see the same attention as the finish you can.
A solid deck starts with the structure underneath it. The decking rests on joists, the joists on beams, and the beams on posts and footings set below the local frost depth. Each part is sized and connected to support the one above it.
Where the deck attaches to the house, we secure the ledger to the structure and flash it carefully so rain drains away instead of finding its way into the wall.
Most of this work disappears once the decking goes down. It is also what keeps the deck strong, level, and solid underfoot.
WHAT IT COSTS
$8,000 to $14,000
For a typical 200-square-foot cedar or composite deck.
Add stairs, railings, or more complex site work, and most projects fall between $10,000 and $20,000.
Every quote is written and itemized before work begins, so you know exactly what is included.
Pricing last reviewed July 2026. Contact us for a current estimate.
Material. The biggest factor. Moving from pressure-treated lumber to Ipe can more than double the material cost.
Railings. Typically $40 to $100 per linear foot, depending on the material.
Stairs. Starting around $500 and increasing with the number of steps and the design.
The site. Slopes, limited access, and existing structures can add time and labor.
What Affects the Price
Permits
Most decks in Seattle require a permit. A permit is required when the deck is more than 18 inches above the ground, built on a roof, or located in an environmentally critical area.
Requirements vary across the Puget Sound. We check the rules for your address, prepare the application, and handle the paperwork before construction begins.
How Long It Takes
Before work begins, we give you a schedule based on the deck, the site, and any permit requirements.
A straightforward deck usually takes one to four weeks to build. Stairs, railings, difficult access, and more complex designs can extend construction to three to twelve weeks.
Permitting happens before construction and follows the reviewing agency’s schedule. We separate permit time from build time so you know what to expect from each.
