Builders use WindsorONE because every stick of WindsorONE is smooth, straight and comes with an industry leading prime coat. Focusing on detail and craftsmanship is what has made WindsorONE a leader in the interior/exterior trim market since 1972. Manufactured in the USA, WindsorONE is a premier choice for lumber solutions.

Craftsmanship Pays

WindsorONE prides itself on its craftsmanship and precision. You can count on sharp crisp edges on all profiles with deep incisions and wide fillets on moldings – creating clean strong lines that make your projects stand out.

Built in America

With two mills manufacturing WindsorONE, one on the West coast in Willits, CA and one on the East coast in Surry, VA – WindsorONE proudly builds in America. This allows them to be vertically integrated from the forest to the lumberyard with W1 quality control. It also allows them to support local lumberyards rather than selling to big box stores.

Health Starts at Home

WindsorONE believes in clean technology that protects to the core. Durable for the exterior and healthy and safe for the interior. All WindsorONE products are safe for interior use, including their Protected boards with Tru-Core®.
