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.

Yes, you absolutely need a permit to add a window to your house. Your contractor can likely obtain this permit on your behalf. Ask about this when getting quotes from multiple window contractors.

Most modern egress windows installed in basements open outward into a window well, although some older homes have in-swing windows. Egress windows, like casement windows used in other parts of the home, such as bedrooms and bathrooms, may open inward, and these windows are often larger than outward-opening windows.

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

DIY is possible for experienced individuals. Professional installation ensures compliance with building codes and proper sealing.
