"They were responsive to every call, did the work professionally and cleaned up nicely.  We would not hesitate to recommend them to friends and family.  We had two leaning columns in the back yard that are now straight and piered so they will never shift again.  They then removed a large area of cracked cement and relayed.  It looks fantastic!

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.

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.

They meet local code demands for escape routes, lighten basements, and aid in reducing overall humidity.

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

The cost of window installation depends on several factors, including the window type, size, and frame material. Labor rates, the need for custom sizing, and any required structural modifications will also influence the final price.
