Our Story

Knebel Windows was founded in 1980, when Patrick Knebel purchased the Miller Rusco Window Company with his wife Margo.

During the 1980s the company expanded to include repair service and became known for its selection of hard-to-find window parts. Over the years the company broadened its product offerings to answer emerging consumer needs such as energy conservation.

The ‘90s brought about several additions including entry doors and sidelights, porch enclosures, commercial storefronts, as well as advances in glass used for insulation and UV protection. Patrick and Margo’s son, Dan, now owns Knebel Windows. He and his brother Andy are involved in all aspects of day-to-day business.

Knebel Windows has evolved into the area’s premiere window company offering a diverse line up of windows and doors along with a complete glass and mirror shop. Our factory-trained service team operates three installation crews with a seven-vehicle fleet. Stop by our showroom at 700 South Capitol Street in Iowa City today.
