"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!"

"I am very pleased with the communication of this company. I reached out to them at a job site and met Leaha's their project manager. The properly got me setup for an estimate of services. I did decide to replace 4 front windows. Deposit was easy to make. Windows came in timely. Yesterday my project manager was also Leah who came first advised me what was going to happen, whom was coming and when. My window team came, two great guys that amazed me how quick they got my windows out. They were upmost polite and respectful of my home and myself. Very little dust and they cleaned up everything. My windows were put in 1982 and I had cracks and they were unsafe. This team worked wonders.....new easy to be clean tilt in windows ...even easy for a woman to move. The window guys the caulking is the best Ive ever seen....so sealed and straight. The went over how to remove screens, clean windows. Kudos to the entire team. Project Manager Leaha drove back...spoke with me, inspected"
