Five generations later, we are committed to keeping our family promise.

Whether you are building, maintaining, or repairing your deck, we can help you find the right decking package for your home. Start your project by visiting one of our nine decking showrooms across the Puget Sound.

We believe in providing you with lifelong value not short term gain. We only stock and sell the highest quality materials, so your projects can withstand the test of time.

Providing you with expert advice and quality materials is only half the job. The other half is getting those materials home safely when promised. We offer a flat $60 delivery for all local orders.

We don't have a guarantee, we have a promise. In 1907, my great grandfather made a promise to the city of Seattle that'd we'd always give our customers and employees a square deal.

Dunn Lumber has been building better lives in the greater Seattle area since 1907. "Legacy of Trust"—the story of Dunn Lumber—is a story of trust and courage, demonstrating Dunn Lumber's steadfastness through a barrage of changes to their industry.

The number one reason to entrust Dunn Lumber with your project is our team. Between our nine locations, we have over 3500 years of experience. All these wonderful people are here to help you free of charge.
