"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!"

"Im am so happy with the work that was done on my house. Tyler came and gave a very fair estimate on lifting my concrete side entrance stairs to my basement. He explained every step of the process and did exactly what we wanted with no issues. Everything was done to perfection. No damage was done and you cant even tell the stairs ever needed a repair in the first place. I would highly recommend this company and would hire again for any future jobs."

"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

The average cost to install an egress window is approximately $3,900, with a typical range between $2,500 and $5,300, though costs can be higher. The final price is influenced by several factors, including the window's size, type, material, and glass quality. Other variables include labor costs, location, excavation needs, and whether permits or a structural engineer consultation are required. The price of the window itself often depends on the number of panes:

  • Single-pane: $100–$400

  • Double-pane: $200–$500

  • Triple-pane: $300–$800

Additional features like window wells or covers will also increase the total project cost. It is advisable to obtain multiple quotes from professionals to get a comprehensive understanding of the expenses for your specific project.

Yes, egress windows are grandfathered. However, this comes with some specifications. If you are remodeling a basement or adding a sleeping area, you’ll need to update the egress windows to be up to proper code. But, if you’re leaving your home as is, you do not have to adhere to these requirements.

Because egress windows are meant for emergency exiting and entering, they need to be an accessible size. The smallest an egress window is allowed to be is 15 inches in width and height, with an opening of around 4 square feet.

Basements are generally required to have windows for your safety. At a minimum, windows should provide an egress in the event of a fire. But basement windows do more than offer a way out; basement windows also offer natural light and ventilation in an area of your home that is otherwise dark and musty.

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.
