He clearly explained what he was doing and offered suggestions for how to mitigate drainage issues that were contributing factors to the water intrusion.

"Efficient, courteous and professional. Needed attic pull down stairs removed to facilitate HVAC work. Harry came out (was the only one who did out of five prospective vendors) reviewed what needed to be done and provided a comprehensive estimate of all work to be done. Work was done as and when promised and area was clean and tidy when the job was finished. Will definitely recommend Harry to anyone who needs handyman help."

"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!"
