"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

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.

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.  

The cost to install a bow window can range from $1,500 to $15,000, with a national average of $3,900. The total price includes materials, which can cost between $1,200 and over $14,000, and labor, which typically adds $300 to $1,900. Several factors influence the final cost, including the window's size and frame material. For example, vinyl frames are the most budget-friendly option, while wood frames are more expensive. Custom features or energy-efficient upgrades will also increase the price. For comparison, a bay window installation typically costs between $1,000 and $7,000.

If improperly installed, an egress window can compromise your foundation’s structural integrity, so it’s important to work with a pro to ensure your foundation remains in good shape. Any money you may save on a DIY egress window installation may cost you in the long run if your foundation is damaged in the process.

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.
