Egress Windows questions, answered by experts

Most professionals can enlarge a window in five to 10 hours, depending on the window location, the exterior wall material, how easy it is to cut through it, and how much buildback you’ll need after the installation is complete. However, more complex projects can take two to three days from start to finish.

Because egress windows are meant for emergency exiting and entering, they need to be an accessible size. The smallest an egress window is allowed to be is 15 inches in width and height, with an opening of around 4 square feet.

The entire window replacement process, from the initial consultation to the final installation, typically takes between four and 15 weeks. This timeline accounts for measuring appointments, ordering, and manufacturing. On the day of the job, the physical installation takes about 30 minutes to two hours per window. A full-house replacement can take one to three days to complete. Factors that can extend this timeline include the total number of windows, custom sizes, complex window types, second-story installations, and any necessary repairs to existing window frames or openings.

Costs depend on window size, type, material, and labor. Custom shapes or sizes typically incur higher expenses; full installation includes removing old windows.

Yes, egress windows can significantly add value to a home. By making basement and attic areas safer and more livable, they allow you to market these spaces as finished living areas, which increases your property's value. Many homeowners can recover the full installation cost, with some sources citing a return on investment of around 70%. The exact value added depends on your specific home, location, and adherence to local building codes. Beyond financial value, egress windows enhance functionality by adding natural light and comfort. They are also a crucial safety feature, often mandated by building codes to serve as an emergency exit.
