"A crew from Groundworks installed eight floor supports and encapsulated our crawl space last week. Jorge, Isaac, Kenny, Zacch, and Anthony did a great job! They worked very long hours to complete our project in a timely fashion and were great to interact with. They identified several plumbing and air duct problems and brought them to my attention. Jorge, the team leader, was great about communicating with me and keeping me well informed. The after job clean-up was very thorough. Jorge has been available by phone for my questions even after they have moved on to another job. These guys are very deserving of five stars. Also, I want to give a shout out to Anthony who did our inspection/estimate. He was very thorough and patient and made everything understandable. Another five-star guy!"

Egress Windows questions, answered by experts

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.

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.

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.

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.

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.
