Egress Windows questions, answered by experts

Adding windows to a house is expensive. Budget roughly $5,800 to add a single window, and double or triple that to add two or three. In some cases, adding a single window can exceed $20,000, depending on the type of exterior wall, the size of the window, the type of window, local permit costs, and other factors.

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.

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

You install a window well 8 to 12 inches deeper than the base of the window sill. After filling the well with drainage rock, the well should sit 3 inches below the bottom of the window. The top of the window well should also be at least 3 inches higher than the surface-grade ground. The window well should be about 6 inches wider than the window opening.

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.
