"Thank you Aaron and Bob for another excellent joy with another window project. We are equally thrilled with the workmanship of the installation and the quality of our new window as we were the last time you did a big window job for us. We appreciate your professionalism and dependability."

"Install crew was perfect. No dust, no mess. Complete cleanup, and a perfect airtight install. For years we have had winter management strategies. Closing off room on the north side... and running space heater in those rooms during use. After installation of the ProEdge windows these rooms are as warm as the rest of the house. AMAZING! Recent warm days prove the advantage of triple glazed low-E windows, too. Nice and cool inside. I searched for years for new windows that met MY specifications . As a career engineer I am happy to recommend ProEdge to anyone. Their attention to detail is superb."

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.

A garden window is about 16 inches to 24 inches deep. This extra space makes room for small potted plants, which is how the garden window, also called a greenhouse window, got its name. Because garden windows jut outward from the house, they need to be installed in a place where they won’t obstruct walkways.

Windows with muntins are slightly more expensive because you’re paying for more material, but the cost shouldn't be that much higher since most muntins are fake on modern windows. You’re looking at a cost between $25 and $100 more per window for muntins, depending on the type. The only exception is if you want custom muntins to match your home style or meet your personal preference. Most manufacturers will charge more for these as they can’t mass-produce them. Windows with true muntins are rare, and they’re much more expensive upfront and over time if you ever need individual glass replacement.

Most properly installed and maintained windows last between 15 and 20 years. Fiberglass windows last much longer than your average window. Since they don’t warp from temperature changes, rust, or rot, you might be able to hold onto fiberglass windows for up to 40 years. On the other hand, poorly maintained wood windows may only last for a few years.

Energy-efficient windows cost more than other window types, but they can help you save on your monthly energy bills, get you some breaks on your taxes, and even increase the value of your home. According to Michael S. Regan, Administrator of the U.S. Environmental Protection Agency, when people invest in green upgrades like energy-efficient windows, they save energy, money, and more.
