"It went very well. While I got their estimate and signed the contract in July, they we not able to do the work until the end of September because they were so busy. The person who came to make the estimate was knowledgeable and understood exactly what I needed and proposed solutions to my problems. The crew that came to do the work did a great job."

Egress Windows FAQs, answered by experts

New window installation costs range from $300 to $1,500 per window, depending on size, material, and energy efficiency features.

An egress window is similar to a regular window. However, this type of window opens fully to allow people to escape the home or rescue personnel to enter the home if an emergency occurs. Egress windows are required in all finished basements before they can be considered a living space.

The primary benefits of an egress window include providing a safe emergency exit, increasing natural light in a space like a basement, and improving ventilation. Additionally, installing an egress window can often increase your property's value.

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

If improperly installed, an egress window can compromise your foundation’s structural integrity, so it’s important to work with a pro to ensure your foundation remains in good shape. Any money you may save on a DIY egress window installation may cost you in the long run if your foundation is damaged in the process.
