Built Strong.
Built to Last.

Vikings Exterior builds every style of custom deck Seattle homeowners want — from simple ground-level platforms to complex multi-level structures with built-in seating, pergolas and hot tub surrounds. Our most popular deck types include: • Ground-level attached decks (most affordable entry point) • Raised decks with under-deck storage • Multi-level decks for sloped Seattle lots • Rooftop decks and ADU decks • Freestanding decks and pool surrounds • Wraparound decks for panoramic views Every deck is designed in-house, permitted with your local jurisdiction, and built by our own crew — no subcontractors.

Choosing the right decking material is the most important decision in your project. Here's how the main options compare for Seattle's wet climate: Cedar: Natural look, affordable upfront cost ($10–$18/sq ft installed), requires annual sealing or staining. Great for traditional Pacific Northwest aesthetics. Composite (generic brands): Mid-range cost ($15–$25/sq ft), low maintenance, fades less than cedar. Quality varies by brand — we only use Grade A composite. Trex (and premium composites like TimberTech, Fiberon): Highest upfront cost ($20–$35/sq ft), 25–30 year fade and stain warranty, virtually maintenance-free. The best long-term investment for Seattle's rain. We carry samples of all materials at our jobsites. Ask your estimator to bring them to your consultation.

In Seattle, a new deck typically costs between $8,000 and $40,000+. The main cost drivers are size (square footage), material choice, height off grade, and design complexity. A standard 300 sq ft cedar deck runs $10,000–$18,000 installed. The same deck in Trex composite runs $15,000–$25,000. Multi-level or rooftop decks with pergolas and built-ins can exceed $40,000.

Any deck over 30 inches above grade, or attached to the home, requires a building permit in Seattle and most King County cities. Vikings Exterior handles all permitting for every project — it's included in our price. Permit processing times in Seattle typically run 2–4 weeks for straightforward residential decks. Bellevue and Redmond are often faster at 1–2 weeks. We've pulled hundreds of permits across Seattle, Bellevue, Kirkland, Redmond, Bothell and Sammamish. We know the local requirements and design our projects to pass inspection the first time.
