We hired this company to remove moisture in about 11 of our windows. This process of drilling holes in windows to remove moisture simply does not work. We contacted the company a few months after the work was completed to tell them our windows still had moisture in them. The owner gave us the run around and told us that his warranty had a series of disclaimers in it and that he would not be giving us a refund. After complaining to the BBB we have now just let the matter go. Don't go with this company they do not stand by their guarantee and you will be just throwing your money away.
