Knebel Windows was founded in 1980 when Patrick Knebel and his wife Margo purchased Miller Rusco Window Company. During the 1980's the company expanded to include repair service, either on-site or in-shop and became known for its selection of hard to find window parts.

As the consumer became more aware of energy conservation and the energy crisis became real, residential replacement windows gained in popularity. Knebel Windows expanded their lines to include a larger selection of storm windows, storm doors and added replacement windows. In conjunction, the service department was beginning to see the demand for more selection. Patterned glass began to take on many different uses - from utilitarian to decorative. Mirror installations were made available, also.

Many changes were prevalent during the decade of the 90's. Knebel Windows introduced a line of entry doors and sidelights, wood and vinyl replacement or new construction windows, porch enclosures, shower doors and commercial storefronts. They have seen many advances in the use of glass and incorporated them into business. Insulated glass has become fairly standard in residential windows with some utilizing Low-E argon gas glass units for increased insulating and UV protection.

Knebel Windows has evolved into a unique business as a full line of window and door dealership with a complete glass and mirror shop. By offering a diverse product line, as well as repair and installation service, Knebel Windows, Inc. has established themselves as the premier window company in the area.

Knebel Windows serves the residential homeowner, the remodeling contractor, the building contractor and area architects.
