"Hired him to install 2 rather large windows. He was very focused and certainly knew what he was doing. His cost estimate was pretty much what it did cost. Very accommodating and not looking to find ways to overcharge. Will be using him again for other work needed around my house"

"The installers of the wallboard were quick and efficient. Did a great job hanging in our new 16 x 32 family room. Even with some of the patch work in other areas of the house they ensured the surrounding wallboard had screws to adequately cover the area before the taper came in. The man that taped and mudded was a true professional. His corners and seams are clean and overall the expertise of the entire crew was exceptional. I would certainly hire this company again."

Egress Windows FAQs, answered by experts

Most professionals can install a window well in two to three days, depending on the size of the well and the window you want inside it. If you’re just replacing an existing window well, the work is much less intensive, and most experts can get the job done in just one day. Connecting the window well to a drainage system or installing a custom concrete window well will naturally take longer, but even the most complicated installations shouldn’t take more than three days.

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.

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.

Egress windows are typically required for basements with habitable space or living quarters. Not all basements or lower levels require egress windows. However, egress windows are required in homes with living spaces such as bedrooms and living rooms in a basement. The International Residential Code and International Building Code require sleeping rooms to have a specific size egress window. Check your local building codes to confirm the requirements in your area.
