Experience The Lomax Difference

Lomax is a local Colorado window and door company with its main office in Fort Collins.

Donovan and Dawn Isaacs are the proud owners of Lomax Window & Door Co. They started building windows in the early '90s in Saint Cloud, MN. Being from the Midwest has given Donovan a strong work ethic and the ability to build like none other. His motto is that it's too cold to do it a second time, so get it done right the first time around! He moved to Colorado in 1999. He has moved up the window ladder through the years, and his knowledge of the industry is incredible! For this reason alone, the opportunity to own and operate Lomax was too good to pass up.

Lomax Window & Door Co

Donovan and Dawn are local Fort Collins residents. They live near Horsetooth Reservoir with their three sons and many, many, fuzzy and feathered friends. The Lomax Window and Door Company team is comprised of family members and employees known and trusted to get the job done.

The Issacs continue to grow and build the Lomax brand with excellent business practices and satisfied customers. Their vision for the Lomax brand is to maintain professional, quality business standards and offer the best replacement window and door products. Lomax strives to keep customer prices reasonable and maintain the highest level of customer satisfaction.
