A Modern Builders Supply, Inc. Distribution Center


Modern Builders Supply, Inc., also known as MBS, was founded in 1944. We have been the leading distributor of building materials in the Midwest for over 75 years. These 75 years in business has afforded us the opportunity to be creative, to become informed, and to respond to the ever changing, ongoing, always exciting needs of our economic society.

Today, MBS has branches in Ohio, Indiana, Michigan, Pennsylvania, and West Virginia.  In all, there are 26 distribution centers across 5 states making MBS the premier distributor in the Midwest.


In addition to being the industry leader in distribution of roofing, siding, kitchens, and so much more, MBS manufactures and markets one of the finest window and door systems offered today. You will see our tractor and trailers going up and down the highways delivering new windows and doors across the country as we proudly display the name of Polaris Windows and Doors.

We offer so many styles and colors that the mind can run wild making selections that will offer personal beauty to individualize each and every home.  MBS has been manufacturing window and doors throughout our history and today we are so proud of the Polaris Window and Door System which creates some of the finest, most energy efficient windows and doors available.
