"The service and care we received from Real Seal was outstanding. Our foundation was sinking and Real Seal came to the rescue. After reviewing and getting several quotes. Real Seal was the one company that took their time and explained every process to us and made us feel safe and secure in our decision. They explained everything throughly and in detail. I knew every step that was done and they even went above what was expected. Austin was always available if we had any questions and if he didn't have the answer he knew who to refer us to for extra assistance. I would Highly recommend Real Seal if you want the job done honestly and throughly. It was well worth the money to have the sense of security that they gave me as a home owner."

Egress Windows questions, answered by experts

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, egress windows can significantly add value to a home. By making basement and attic areas safer and more livable, they allow you to market these spaces as finished living areas, which increases your property's value. Many homeowners can recover the full installation cost, with some sources citing a return on investment of around 70%. The exact value added depends on your specific home, location, and adherence to local building codes. Beyond financial value, egress windows enhance functionality by adding natural light and comfort. They are also a crucial safety feature, often mandated by building codes to serve as an emergency exit.

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.

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

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.
