As a owner of Merrie Senior Services, LLC working with seniors, I have had the opportunity to refer Jack to a few clients to get their windows cleaned. He does a very thorough and detailed job. Not only the paying attention to a great job of cleaning the windows and the details of cleaning rails, screens: He arranged to clean the blinds for them. Jack is very professional, considerate, honest, and trustworthy. He exhibits genuine kindness, understanding and compassion to all people.
