"A wonderful experience all around! We had 15 windows and a sliding glass door replaced. Our Salesperson, Harlan, was very professional and explained the benefits of the new windows and all about Power as a company. The installers arrived on time and completed the entire job in a day! Everything was installed perfectly and the crew was courteous and cleaned up after themselves. Erin came to visit the next day to make sure everything was up to their standards and addressed any questions we had. Most certainly the best experience we've ever had with a home contractor. Highly Recommend!"
