Egress Windows questions, answered by experts

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.

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.

The proper way to install a window well is to measure the window, dig a hole deeper and wider than the window, place a drainage tube and cap, anchor the well to the foundation, caulk the seam, and backfill the hole. The job requires tools such as a hammer drill and auger and some heavy digging. Proper placement and window well installation are critical to preventing water from leaking into the window.

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.
