Cedar Decking Mercer Island WA

Why Mercer Island Homeowners Choose Cedar Decking

Western red cedar is the original King County deck material — grown in the Cascades, milled locally, and suited to the PNW climate better than any imported wood. We build cedar decks for homeowners who want the natural grain, the smell of fresh-cut lumber, and are committed to the annual maintenance that keeps cedar looking its best.

Mercer Island Specifically

Cedar replacement is our most common Mercer Island project — not cedar installation. The Island's Lake Washington humidity creates conditions where cedar decks decay at ledger and post connections faster than visible surface wear suggests. If you have an existing cedar deck on Mercer Island, a free structural assessment is worth scheduling.

Cedar grows 30 miles east of Seattle. It's naturally rot-resistant, dimensionally stable in Pacific Northwest humidity, and carries a natural warmth that composite can't match. The honest conversation: cedar requires annual staining or sealing and realistically lasts 15–20 years in King County's wet climate before replacement. We build cedar for clients who understand that maintenance cycle.
