Millwork is our specialty, Not a sideline

Welcome to Broad Building Supply! We are a locally owned wholesale millwork distributor located in Columbia, MO. We specialize in exterior and interior door units, as well as other millwork items. Deliveries are made on our own fleet of trucks to lumber yards & home centers throughout Missouri, Western Illinois & Eastern Kansas.

While other distributors use millwork as an "add-on" item, at Broad Building Supply, "Millwork is our Specialty, not a Sideline". Give us a call at 800.537.1999!
