Proudly Serving Greater Madison and surrounding Wisconsin area from the southern Wisconsin state line north to Oshkosh and west to Tomah

Feldco has been installing custom replacement windows, siding and doors in the Madison area since 2006. After nearly 30 years of delighting customers in Illinois and Indiana, Feldco began serving Wisconsin with the same goal of providing customers with the very best value and customer experience for their residential window, siding and door projects.

In 2009, Feldco opened our office on Stoughton Road to serve the Madison community directly with local Monona, Sun Prairie, Middleton and other Madison area employees trained to provide the same superior quality, professionalism and craftsmanship with our Feldco window, siding and door installation. Feldco now has thousands of delighted customers in the Madison area and surrounding all the way from Oshkosh to Beloit.

Feldco is proud to be a member of the Madison community, and strives to be a leader by creating opportunities for both employees and the company as a whole to give back to the Madison and Wisconsin communities. Through partnerships with the University of Wisconsin, the Packers, the Mallards and other organizations like the Down Syndrome Association of Wisconsin, and The Great Country Pumpkin Patch, Feldco works to serve those in need, as well as donations and employee work with numerous local charities, churches, youth groups and teams.

Our Madison location on Stoughton Road serves as a customer showroom, where you are welcome to view our exclusive line of replacement windows, siding and doors. Whether you are looking for a standard double-hung window, an elegant bay or bow window, or any variation of patio sliding door, fiberglass entry door or steel security door, we are confident we have the solution to make your home more beautiful, comfortable, secure and energy-efficient.
