"All I have say is EGRESS PROS is the best of the best. If you need an egress window, look no further..Egress Pros are the champions! Their Sales Team is top notch, patient, and knowledgeable. Ryan and Ron came to the house on multiple occasions to answer all my questions, give me Ideas and recommendations for the project and put my mind at ease with the concerns I had, all with no pressure to sign with them. When I finally pulled the trigger on the project, Egress Pros sent, what I consider their best... Carlos! CARLOS IS THE MAN! Carlos arrived exactly on time with the crew. He walked around and explained what he was planning on doing to knock out the job. Carlos literally built a self-enclosed workspace for himself inside the house. When he told me the job was done i couldn't believe my eyes. The installation quality was unbelievable, and Carlos didn't leave a spec of dirt inside and out. One of the big concerns I had was how the finish on the inside would look, but Carlos is a real pro and built such a nice pocket and framed out the window perfectly. It looks like the house came with that window. He is that good. I hope the bosses at Egress Pros take care of him in the same way he took care of me. i wish i could give more than 5 Stars!"

"My entire experience with AM was excellent. Office personnel were very helpful and professional. Service person was also very professional and courteous. Did his job very well and obviously took pride in his work. The service involved cleaning out both of my 2 year old egress windows. AM had installed those windows, which was also done very well. I give them the highest rating."

Egress Windows FAQs, answered by experts

Most professionals can enlarge a window in five to 10 hours, depending on the window location, the exterior wall material, how easy it is to cut through it, and how much buildback you’ll need after the installation is complete. However, more complex projects can take two to three days from start to finish.

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.

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.

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.

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