    Why Natural Wood Decking Remains a Top Choice

    Composite decking has grown in popularity — and we install it too — but natural wood remains the material of choice for a significant segment of King County homeowners. Here’s why:

    Authentic Natural Beauty — Real wood offers warmth and character composite can’t match.

    Strong & Dependable — Pressure-treated lumber delivers proven structural performance.

    Customizable Style — Stain or paint wood in any color you choose.

    Cost-Effective Option — Lower upfront cost than composite or hardwood decking.

    Perfect Northwest Look — Cedar and redwood fit the Pacific Northwest aesthetic naturally.

    Frequently Asked Questions — Wood Deck Installation in King County

    How long does wood deck installation take?

    Most residential wood deck projects take 5–10 business days from start to final inspection, depending on deck size, complexity, and permit review timeline. Simple ground-level platforms may be completed in 3–5 days. Multi-level or complex builds with pergolas and built-in features may take 2–3 weeks.

    Do I need a permit for a wood deck in King County?

    In most cases, yes. Any deck attached to a home, any deck over 30 inches above grade, and any deck over 200 sq ft typically requires a building permit in King County. We handle the entire permit process for every project that requires it.

    How long does a wood deck last in the Pacific Northwest?

    With professional installation and regular maintenance: pressure-treated lumber lasts 15–25 years; cedar and redwood last 20–30 years; tropical hardwoods can last 25–50 years. Maintenance frequency and quality are the biggest factors in actual lifespan.

    Should I choose wood or composite decking?

    Wood offers lower upfront cost, a natural aesthetic that no composite fully replicates, and full paintability/stainability. Composite offers lower lifetime maintenance cost and better resistance to the wet King County climate without periodic sealing. We install both and can help you evaluate which fits your priorities, budget, and long-term plan for the deck.

    Can you repair or replace boards on my existing wood deck?

    Yes. We provide targeted deck repair and full re-decking services — replacing individual damaged boards, full deck surfaces over sound existing framing, and structural component repair. We can also upgrade a re-decking project to composite while we have the frame exposed.
