"Jeremy and Rochelle were so professional and friendly from the very beginning even when they just came out for a qoute. I am so IN LOVE with my new fence they built for my dogs. It came out better than I could have ever imagined. I could not thank them enough for their hard work. Will definitely be using them for future projects!"

Egress Windows questions, answered by experts

Yes, egress windows are grandfathered. However, this comes with some specifications. If you are remodeling a basement or adding a sleeping area, you’ll need to update the egress windows to be up to proper code. But, if you’re leaving your home as is, you do not have to adhere to these requirements.

Yes, you absolutely need a permit to add a window to your house. Your contractor can likely obtain this permit on your behalf. Ask about this when getting quotes from multiple window contractors.

Adding windows to a house is expensive. Budget roughly $5,800 to add a single window, and double or triple that to add two or three. In some cases, adding a single window can exceed $20,000, depending on the type of exterior wall, the size of the window, the type of window, local permit costs, and other factors.

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.

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.
