"They've done work for me twice now. Great work both times. They were very careful and thorough in their use of protective floor and wall covering. The tile work is very neat and clean, without any rough spots left in difficult corners."

"As you know finding companies to work on your private home, is very frustrating. I was impressed by Oliver the foreman from estimate to completion of the job. The honesty and integrity were the part of the job to make me confident that I had made a score in finding a professional company. Not only do I recommend them, but I am keeping their contact information!"

"We are completely delighted. Everything went perfectly. Danny, our sales representative, was great at explaining options, and was always available for questions. The expert installers, Andreas and Dmitri, were fun to work with, responsive to our requests, and even installed our new doorbell. I look forward to working with this excellent company again for new windows."

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.

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

The entire window replacement process, from the initial consultation to the final installation, typically takes between four and 15 weeks. This timeline accounts for measuring appointments, ordering, and manufacturing. On the day of the job, the physical installation takes about 30 minutes to two hours per window. A full-house replacement can take one to three days to complete. Factors that can extend this timeline include the total number of windows, custom sizes, complex window types, second-story installations, and any necessary repairs to existing window frames or openings.

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.

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.
