"We just needed the pane in one window replaced. They came to look at it the same day I called. He measured and ordered the window in less than 10 mins. As he said, 10 days later the window pane arrived. They came and installed the window that day in less than half an hour. The service was great, timely and affordable. I will definitely remember them for any future window replacements."

"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

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

Storm windows provide several key benefits. They offer improved insulation and soundproofing, which adds comfort to your home by regulating internal temperatures and blocking external elements. Storm windows also help reduce energy costs by preventing cold or hot air from getting inside. Additionally, they can protect the primary glass in your windows against weather damage.

Most windows last between 15 and 30 years. The exact life span depends on a few things, including the frame material, the quality and type of glass, the weather in your area, whether or not the window is installed properly, and more. You can always speak with a window professional about whether or not it’s time to replace your windows or if repairs would be more affordable. You’ll need to consider the cost of replacing your windows, the cost of repair, and the longevity of each solution.

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.

Yes, you can replace the frame around a window by completing either a partial replacement or a full replacement. With a partial replacement, your window specialist will remove the trim around the window and replace or repair just the damaged portion. For a full replacement, your tech will need to remove the window, replace the frame, and then reinstall the window.
