"Trying to execute a major outdoor renovation project during a time of global supply chain disruptions poses many challenges. Happy to report that Mal and PHI navigated that rocky path very well. Mal kept us informed of the many changes coming from the supplier as far as colors and delivery. It was a long process...8 months between signing the contract and having the work completed. In the end we are very happy with the product and the quality of the work. A major windstorm hit the area the day after the work was completed and put the installation to the test. Everything held up perfectly...no loose bits flapping on the house or flying around the yard. In researching this project ahead of time, we had spoken with many friends who've had their siding replaced and none of them were especially happy with their contractor. We had the best experience with Mal and PHI. Highly recommended."

Egress Windows questions, answered by experts

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.

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

There are a range of egress window types available, including:

  • Single-hung: $100–$400

  • Double-hung: $250–$500

  • Horizontal/sliding: $150–$800

  • Casement: $200–$500

  • In-swing: $350–$700

When choosing a type of egress window, consider how you’d like to open it. For example, double-hung egress windows open from top to bottom and let plenty of fresh air in, whereas sliding windows slide open for easy access.  

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