In 2003 “The Window Shop” was established in Corsica, SD. As the business rapidly grew, we relocated to the Main St Historic district in Mitchell, SD, in 2007. We service all of eastern South Dakota, Northeastern Nebraska, and Southwest Minnesota. Ben, the owner of the “The Window Shop,” has over 35 years of experience in the Home Improvement industry. From the beginning, he envisioned a company where he could work side by side with family, friends, and community.
