Proudly Serving Greater Rockford and the surrounding Northern Illinois communities south to Mendota, west to Sterling, Mt. Carroll, and Stockton, and north to the Wisconsin border

Feldco was born in Chicago back in 1976 with a goal of providing homeowners the very best value and experience with their home improvement projects. Feldco has been installing custom replacement windows, siding and doors in the Rockford area since 1985. After a decade of delighting customers in Chicago and Northwest Indiana, Feldco began serving Rockford with the same goal of providing customers with the very best value and customer experience for their residential window, siding and door projects.

In 2007, we opened our Feldco Rockford office on Perryville Road to serve the Rockford community directly with local employees from Rockford, Loves Park, Belvidere and Machesney Park trained to provide the same superior quality, professionalism and craftsmanship with our Feldco window, siding and door installation. Feldco Rockford now has thousands of delighted customers in the Rockford area and surrounding Northern and Western Illinois communities from Stockton to Mendota.

Feldco is proud to be a member of the Rockford community, and strives to be a leader by creating opportunities for both employees and the company as a whole to give back to the Rockford and Illinois communities. Feldco Rockford has been an avid partner of the Rockford Ice Hogs, the Rockford River Hawks and the Rockford MetroCentre. Feldco has also lent support to the Rockford Girl Scouts, The Arc of Winnebago, Boone and Ogle Counties for People with Disabilities, and numerous area community, youth and charity organizations.

Our Rockford location 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.
