Egress Window Installation in Waukesha County, WI

A below-grade egress window, with the opening cut into the foundation, the window, the well and the drainage, typically runs $2,500–$5,500 per window. Poured concrete or block, how deep the well goes, the window style and finishing the inside move the price, and your written quote after the inspection (if qualified) is the real number.

For homes covered by Wisconsin's Uniform Dwelling Code, an exit window needs a net clear opening of at least 20 by 24 inches, and the bottom of the opening can be no more than 46 inches above the floor, or up to 60 inches with a permanent platform below it (SPS 321.03). A window below grade needs a well at least as wide as the window and 36 inches out from the wall, with a ladder or steps once it is more than 46 inches deep. The code covers homes built since June 1, 1980; for older homes, your municipality decides which rules apply.
