"Always Waterproofing did a fabulous job on installing an egress window in my basement. They ran into an unforeseen pipe and ended up moving it and doing additional drywall work. I would highly recommend them for any projects. Professional, fair pricing and communicative."

"We are very pleased with the work that was done. Hats off to Janilo Ugalde, a one man crew. Not only did he do the job himself, but even took time showing us and explaining what he did as he went along and cleaning up after the job . We hope he is commended and rewarded for a job well done. We also want to thank Lon Brankovich, Foundation Specialist for all his help in explaining everything that would be done. Really a great help."

Egress Windows FAQs, answered by experts

Most professionals can enlarge a window in five to 10 hours, depending on the window location, the exterior wall material, how easy it is to cut through it, and how much buildback you’ll need after the installation is complete. However, more complex projects can take two to three days from start to finish.

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.

DIY is possible for experienced individuals. Professional installation ensures compliance with building codes and proper sealing.

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.  

Basements are generally required to have windows for your safety. At a minimum, windows should provide an egress in the event of a fire. But basement windows do more than offer a way out; basement windows also offer natural light and ventilation in an area of your home that is otherwise dark and musty.
