Dunn Lumber

What Dunn Lumber does

Dunn Lumber Company, Inc. is a privately held building materials retailer incorporated in Washington State and headquartered at 3801 Latona Ave NE in Seattle. Founded in 1907, the company operates nine retail showroom locations across the Seattle metropolitan area (Bellevue, Everett, Green Lake, Lynnwood, Renton, Kirkland, Shoreline, Lake Union, and Normandy Park) and serves two primary customer segments: do-it-yourself homeowners undertaking home improvement and deck-building projects, and professional contractors requiring reliable supply of construction-grade materials. The product portfolio spans fourteen organized departments including Deck HQ (a specialty deck-building category with 480+ decking SKUs from TimberTech, Trex, Fiberon and others), Lumber & Plywood, Building Supplies, Tools & Equipment, Hardware, Plumbing & Drainage, Electrical & Lighting, Paint & Stain, Heating & Cooling, Home & Garden, Clothing & Protective Gear, and Weatherproofing.

The business operates a sales-led, multi-channel go-to-market model. In-store showrooms specializing in Deck, Moulding, Windows, Doors, Cabinets, and Outdoor Living serve as both retail and consultation environments. An owned Magento-based e-commerce storefront extends the catalog online with a 'Ships Via Dunn Lumber' delivery option, while a dedicated contractor sales program and commercial/industrial sales service provide account management, volume pricing, and project support to professional buyers. Marketing is anchored by two segmented content platforms, Dunn DIY for consumers and Dunn Solutions for trade professionals, which serve as top-of-funnel acquisition channels.

Revenue is generated through three primary streams: retail point-of-sale transactions on lumber, building materials, hardware, and tools; contractor and commercial sales accounts with volume-based pricing; and the Dunn Delivers delivery service. Pricing is not publicly disclosed; product listings show starting prices that vary by selection. The company maintains the 'blue-end studs' quality guarantee and a stated competitive position built on 115+ years of regional operating history, deep category depth in decking, and a local showroom footprint that competing direct-to-consumer brands cannot easily replicate.
