Windsor Mill was founded in 1972 by Raymond A. Flynn. Originally referred to as Cal-Waii Moulding, Inc. for its West Coast Redwood and Douglas Fir molding sales, the company soon began selling coast-to-coast. Shortly thereafter, Windsor Mill began exporting in addition to purchasing its second plant and first international office.

Today, Windsor Mill has grown into one of the largest manufacturers of high quality specialty lumber, molding and millwork. We hope the Windsor Mill way is evident to you-we have adhered to high levels of quality and manufacturing standards during times when it would have been easy to lower our standards to sell at higher volumes and create normal wood product headaches for our customers. That's not us. We work everyday to eliminate downstream customer problems such as claims and call backs.
