Deck Builder in Seattle & King County
Custom outdoor living spaces built to last
Complete Consulting and Construction builds custom decks for homeowners throughout Seattle and King County, from Tukwila to Renton, Burien, and Kent. Our regional climate means we design and build with drainage, moisture resistance, and year-round durability in mind — not just how a deck looks the day it's finished. Every deck starts with a free on-site consultation covering material options, footing requirements, and permitting.
The Deck Building Process
From design to final walkthrough, here's what to expect.
Site Visit
We assess grade, drainage, sun exposure, and how the deck should connect to your home.
Design
Material selection, layout, and any permit drawings needed for your jurisdiction.
Permitting
We file for and manage permit approval with your city before construction starts.
Construction
Footings, framing, decking, and railings, with a final walkthrough when it's done.
Custom Wood Decks
Experience the timeless beauty of natural wood decking. We work with premium materials including cedar, redwood, and pressure-treated lumber to create stunning outdoor spaces. Each deck is custom-designed to complement your home's architecture and maximize your outdoor living potential, with proper flashing and drainage details to handle our wet Pacific Northwest winters.
Composite Decking
For homeowners who want beauty without the upkeep, our composite decking solutions deliver. Using top brands like Trex and TimberTech, we build decks that resist fading, staining, and scratching while requiring no sealing, staining, or painting — a real advantage during our long rainy season when maintenance windows are short.
Multi-Level & Custom Features
From multi-level designs and built-in seating to pergolas and outdoor kitchens, we create complete outdoor living experiences. Our design team works with you to incorporate features like lighting, railings, and privacy screens that make your deck truly unique, and we regularly design multi-level layouts for the sloped lots common throughout Seattle and King County.

Deck Building FAQ
Do I need a permit to build a deck in Seattle or King County?
Most decks attached to a house, or any deck built above a certain height off grade, require a building permit in Seattle, Tukwila, Renton, and the surrounding jurisdictions. We handle the permit application and inspections as part of your project so you don't have to navigate city requirements yourself.
Wood or composite — which is better for a Seattle deck?
Both hold up well here, but they trade off differently. Cedar and pressure-treated wood cost less upfront but need periodic staining or sealing to handle our wet winters. Composite from brands like Trex and TimberTech costs more initially but resists moisture, fading, and rot without annual maintenance — a common tradeoff for Pacific Northwest homeowners deciding between the two.
How long does a deck build take?
A straightforward single-level deck typically takes 1-2 weeks from groundbreaking to completion. Multi-level decks, built-in seating, pergolas, or outdoor kitchens add time for framing and finish work — we give you a project-specific schedule after the design walkthrough.
Can you build a deck on a sloped yard?
Yes. Sloped lots are common throughout Seattle and King County, and they're usually a good fit for multi-level or elevated deck designs. We assess grade, drainage, and footing requirements during the initial site visit and design around the terrain rather than fighting it.
