about us

Our goal is not to be “just a supplier”, we want to work hand in hand with each customer to make every project successful and unique. 


In early 1994, Bob Haub and Mike Bruns decided that there was a need to change the face of millwork and windows in the Sioux Empire. On August 1, 1994, that idea became a reality when Builder’s Millwork & Window was established. Focusing on a service-first attitude, Builder’s Millwork & Window leaped head-first into the new construction market, providing customers with quality windows and millwork with an unmatched level of customer service. Today, Builder’s Millwork & Window has grown into a truly full-service company with over 30 employees. Their state-of-the-art Design Center on East 10th Street in Sioux Falls is second to none in the upper midwest.

When asked, Bob and Mike will tell you that always looking ahead and never being afraid to change are keys to success. However, Builder’s Millwork & Window still maintains their service-oriented attitude and wide variety of quality products. Their goal is not to be “just a supplier”, they want to work hand in hand with their customer to make every project successful and unique. Whether it’s custom wood windows, fine architectural millwork or creative kitchen design, Builder’s Millwork & Window is your one-source provider. Stop in to their beautiful Design Center Showroom today and let them help you make your new home or remodel project dreams come true.

Bob Haub

Bob has provided expertise in millwork and window design and service in a growing and expanding market for many years. He started working at a lumber yard in Sioux Falls, SD right after high school and started managing at the yard at the age of 19. He later joined a local glass company.  He was made part of the management team there and started a residential department which he helped grow into a sizable segment of the business. He and Mike Bruns started Builder’s Millwork & Window in 1994. He has been creating both interior and exterior beauty and superior function through doors, windows and millwork in new construction and remodels as well as developing a business where service is a main objective and clients are number one.

Mike Bruns

Mike Bruns has served contractors and their clients in construction for the majority of his career. Mike holds an Associates Degree in Building Construction Technology and a Bachelors in Industrial Technology.
