Contractor Services

Service. Inventory. Pricing.

As a contractor, you need three things from your lumber, building materials and hardware supplier: dependable service, quality products and competitive prices. We deliver all three!

How do we do it? Our membership with Castle Building Centres ensures pricing that competes with the box stores. Being independently owned and operated, we can source the world for the brands you love and the products you need. No one surpasses our knowledge of the industry. Ask us, and we'll get it! That is our promise to you!
