In 1946, two brothers Herb & Ervin Kolbe started a business repairing and building windows and door frames out of their small wash house located on the 80-acre family dairy farm in Marathon, Wisconsin. Since then, Kolbe & Kolbe has grown into a nationally recognized leader in the luxury window & door industry selling its products all throughout the United States, Canada and beyond. 

Kolbe is proud to build windows and doors that are found in some of the most visionary residences and commercial projects in North America.  Architects and discerning individuals who take building to new levels turn to Kolbe for professional-grade windows and doors that are built to high standards. Imagine the endless possibilities of your vision, and look to Kolbe for innovation, distinctive options and custom solutions and bring them to life.
