Westside Building Supply, founded in 1959, is one of the largest independent, family-owned building material retailers in the Pacific Northwest, and serves contractors and do-it yourselfers through its large lumberyard facility as well as a modern, vibrant retail store building. Westside specializes in complete house packages, installed sales programs such as kitchen and bath cabinets, garage doors, prompt delivery, and expert service.
There are certain things you expect to find at a Lumber Yard and Home Center like lumber, plywood, hardware, roofing, and paint, but at Westside there is much more.
