Our oldest son David (picture below!) owns a window cleaning business called Russel Williams. The website for his company is http://www.russelwilliams.com. I also added a link to the website in the Links box on the left. They provide full service interior and exterior window cleaning, as well as holiday lighting, chandelier cleaning, gutter cleaning, and other services.
If you have any window clean needs, give him a call! They really do outstanding work.
