"Chad and Scott did a fantastic job, from concept to completion of our project. We needed an interior wall, framing, door, drywall, texture, & painting, & all the details to enclose our kitchen from our entry. They understood our concept, and had the work done from start to finish in 2 weeks. Meticulous, detail-oriented, polite, & fun to have them here in our home are how we would describe our relationship with Chad & Scott. They even let us keep adding other small projects along with the wall construction, always being cheerful & accommodating. We would definitely recommend them to our friends & neighbors for any projects! Susan & Larry"

Egress Windows questions, answered by experts

You install a window well 8 to 12 inches deeper than the base of the window sill. After filling the well with drainage rock, the well should sit 3 inches below the bottom of the window. The top of the window well should also be at least 3 inches higher than the surface-grade ground. The window well should be about 6 inches wider than the window opening.

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.

Expect excavation below grade, creating a well for access, weatherproofing, and thorough inspections during setup.

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.

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.
