County Line Lumber Co. was founded in 1985 to fulfill the needs of area builders. In 1987, lumberman Bill Dowd purchased the fledgling business and turned it into one of the Front Range's premier lumberyards, known for providing contractors with access to an exclusive supply of high quality building materials. Today we have expanded our offerings beyond just the lumberyard. Professional builders and homeowners alike can now find everything they need to successfully complete projects of any scope.
