We have had a slow but persistent leak in the ceiling of our second floor bathroom that several handymen and plumbers could not detect the source. We got referred to Attila to look at a damaged section on our evestrough (he cleans eves). He doesn't do this type of work but when we found out that he is a licensed plumber we had him look at the leak. With the aid of a tiny camera on a snake attached to a small monitor he determined the origin of the problem and fixed it. We thought that we might have to take apart our third floor bathroom but instead had to open a small hole for the repair. I would definitely use his services again if needed.
