"Great customer service they arrived on SAID time ON time. They didn't leave until the job was completed. I spotted one small flaw but nothing to complain about other than that they did a great job. They cleaned up behind themselves. I had to disposed of all the trash myself but they did put all the trash in bags and sat them outside nice and neat and it was also in the contract that the customer is responsible for disposal of trash. It was not a surprise. This properly why the cost was reasonably priced. I will use them again."

Egress Windows FAQs, answered by experts

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 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.

The entire window replacement process, from the initial consultation to the final installation, typically takes between four and 15 weeks. This timeline accounts for measuring appointments, ordering, and manufacturing. On the day of the job, the physical installation takes about 30 minutes to two hours per window. A full-house replacement can take one to three days to complete. Factors that can extend this timeline include the total number of windows, custom sizes, complex window types, second-story installations, and any necessary repairs to existing window frames or openings.

Egress windows are typically required for basements with habitable space or living quarters. Not all basements or lower levels require egress windows. However, egress windows are required in homes with living spaces such as bedrooms and living rooms in a basement. The International Residential Code and International Building Code require sleeping rooms to have a specific size egress window. Check your local building codes to confirm the requirements in your area.

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.
