Egress Windows FAQs, answered by experts

Installing a window well costs anywhere from $500 to $1,500 or more. Adding an egress window and well runs about $3,900 on average. Adding a window well cover to the project can add $200 to $700. A well cover helps protect your egress windows from weather damage and keeps them clear of dirt, debris, and wildlife.

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.

There are a range of egress window types available, including:

  • Single-hung: $100–$400

  • Double-hung: $250–$500

  • Horizontal/sliding: $150–$800

  • Casement: $200–$500

  • In-swing: $350–$700

When choosing a type of egress window, consider how you’d like to open it. For example, double-hung egress windows open from top to bottom and let plenty of fresh air in, whereas sliding windows slide open for easy access.  

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.

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.
