Duane fixed a very persistent leak on the metal roof of our back porch. The source of the leak was very difficult to locate but Duane proved more persistent than the mystery leak. Duane is honest and trustworthy. He will honor his warrenties and not try to sell you anything to don't actually need. In fact he'll talk you out of spending money unnessiarily. I would recommend E.M. Blue and would use them again.
