Egress Windows questions, answered by experts

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.

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 few ways to save money on egress window installation. First, choosing pre-fabricated windows instead of custom windows can help dramatically reduce the overall cost. In addition, skipping window extras, like customized frames or window film, can help save money on the price tag without sacrificing the window itself. You should also shop around to multiple window installers to find the best installation deal without sacrificing the quality of the window.

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.
