Midwest Construction and Great Lakes Windows have been partners since 1985. When our family decided to get into the window business, the search was on. Our Father, the founder of Midwest Construction & Supply Inc. took myself, my twin brother and oldest brother to 5 different window factories in a two year period before he made the decision to partner up with Great Lakes Window. The reason he choose Great Lakes Window, they had the best research and development department than all of the other combined.

Midwest Construction needed a window partner who could provide a custom built window to fit into the existing opening. To be safe and easy to clean and maintain, offer exterior colors and interior wood grain, while other companies only had white or beige windows. The most important decision was energy efficiency with a great warranty! Great Lakes Window provided that back in 1985 and still provides us with the most updated energy efficient glass options available in our industry!
