Friendly Windows, Corp. is a general contractor specializing in window installations and repairs, as well as roofing, siding, and gutters for residential and commercial customers. Located in Des Plaines, IL, this company serves the northwest suburbs of Chicago, including Mt Prospect, Elk Grove Village, Park Ridge, Prospect Heights, Schiller Park, Morton Grove, Glenview, Bensenville, Northbrook, Arlington Heights, Niles, Norwood Park, Wood Dale, Wheeling, Edison Park, Rosemont, Rolling Meadows, and Palatine.

The company installs a variety of windows, including casement windows, double hung windows, patio windows, slider windows, bay and bow windows, and fiberglass windows. Their casement windows include hardware that is made with steel and then sealed with a corrosion-resistant coating to ensure that the hardware lasts as long as the window. All of the company's units are supplied by Advanced Window Corporation, which guarantees airtight function due to be wet glazed during production, an important feature because of Chicago's harsh winters and strong windstorms. The company also provides roofing, siding, and gutter installation, which work together to provide the exterior aesthetic of a home or business.
