Windows of Wisconsin – Replacement Windows in Appleton and Green Bay, WI

Replacement Windows Are Color Matched to Match Existing Trim PRIOR to INSTALLATION!

Unlike other replacement window companies Windows of Wisconsin color matches our Infinity from Marvin replacement windows to match the existing trim in your home. After consulting with the homeowner our expert stain matching team formulates the perfect color at our facilities which will maintain the beauty and continuity of the woodwork in your house. A sample of the custom formulated stains are approved by the homeowner and applied to the windows prior to installation. This ensures a hassle free and no fuss process that eliminates follow up visits and third party painters. Once your windows are installed you can enjoy the appearance and superior performance of the engineered EverWood interior woodgrain finish.
