"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 FAQs, 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.

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 primary benefits of an egress window include providing a safe emergency exit, increasing natural light in a space like a basement, and improving ventilation. Additionally, installing an egress window can often increase your property's value.

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