In 1961 Don M. Copeland, owner of a large St. Paul lumber yard, bought a defunct lumber yard in the community of Gladstone (part of Maplewood) and named it Gladstone Lumber Mart. The retail operation sold lumber and building materials for many years until a decision was made to focus on windows, doors and related millwork. The business was then renamed Gladstone’s Window & Door Store and has since specialized in window and door sales and installation.

We have proudly retained our family owned and operated roots since our business was founded almost 50 years ago. Interwoven with a history of steadfast commitment to customer service, Gladstone’s today is a highly regarded dominant force in the Twin Cities replacement window and door market. A reputation built on personalized customer service based on family values. A business that customers can trust.
