ABOUT US

At 406 Window Co. relationships drive our business. These relationships are developed from our owner, Brian Reay, and his own personal beliefs that have been in the industry for 35 years. Brian started his career as a young man taking home construction classes at the Career Center in high school.

He worked at Knox Lumber for 15 years starting at the bottom working up to management. In 1995, Brian saw an opportunity to start 406 Window Co. carrying on his experiences in building homes, management training, and customer service over to the new business adventure. Montana Window & Door has been family based since the beginning. His wife, Robyn, has supported him in management and marketing throughout the years and continues to be involved. The Reays have three grown children: Lynde, Aaron, and their youngest Austin. All the children have grown up helping in some way with 406 Window Co.
