Your Window & Door Repair Specialists!

We Repair ALL Window Brands

At KELLAN Window Repair, repairing windows and doors is our specialty! We service and repair nearly all brands of windows and doors. Every week we save Wisconsin homeowners thousands of dollars by repairing and restoring windows they thought needed replacement! We work with home owners and businesses throughout Northeast Wisconsin - Green Bay, Appleton, Oshkosh, Fond du Lac, and Door County.


In those cases where replacing your windows (and doors) is the better option we can provide homeowners with a vast variety of window brands and styles. We don’t just say “our window is best” simply because that’s the brand we happen to sell. Quite the opposite actually. We work with several window companies and dealers which allows us to offer the best solution to meet your specific needs. Our window technicians are expertly trained to perform window installation to only the highest standards in the industry.

"Jarrett did a wonderful job installing new windows in my house. The older windows were not standard and Jarrett immediately came up with a solution to make the new windows fit. He is efficient, personable, and his work is top notch." -Jay S. - Appleton, WI
