Egress Windows questions, answered by experts

Depending on size, material, and labor, two windows can cost between $600 and $1,600.

Most professionals can install a window well in two to three days, depending on the size of the well and the window you want inside it. If you’re just replacing an existing window well, the work is much less intensive, and most experts can get the job done in just one day. Connecting the window well to a drainage system or installing a custom concrete window well will naturally take longer, but even the most complicated installations shouldn’t take more than three days.

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.

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

Egress windows are typically required for basements with habitable space or living quarters. Not all basements or lower levels require egress windows. However, egress windows are required in homes with living spaces such as bedrooms and living rooms in a basement. The International Residential Code and International Building Code require sleeping rooms to have a specific size egress window. Check your local building codes to confirm the requirements in your area.
