"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."
