Frequently Asked Questions
Do you keep lumber in stock?
Common sizes stay on the yard. Special lengths and specialty treatments we order in. Call or text (509) 479-9975 and we will tell you what is here today.
What is the difference between treated and regular lumber?
Regular framing is kiln-dried fir and larch for walls, roofs, and interiors. Treated lumber is for weather, concrete, or dirt — decks, sill plate, fence posts, and outdoor framing. For barns and posts that stay in the ground, we carry Wolmanized Heavy Duty Wood.
What is Elite Decking?
Factory-finished cedar-brown wood decking. We carry the boards plus matching posts and rail stock, and we can add Regal Ideas railing if you want a finished system.
How do I get a lumber price?
Send a list or call (509) 479-9975. Quotes are free for contractors and homeowners. 7/16" 4x8 OSB is posted on the panels page; other lumber is priced to the sizes and lengths you need.
