I had a leak in my 4plex building. The upstairs was leaking into the downstairs. They came and replaced a wax ring before, but this time it was a different issue. Billy came out to assess the situation and discovered that the angle stop on the toilet needed to be replaced. Upon further inspection of all the angle stops throughout the bldg, Billy recommended that they should all be replaced eventually. I decided to do them all this wknd. Billy came out and replaced them all. Some were so bad that he had to cut them off (its an old bldg). Billy was professional and really knew what he was doing. I'm definitely going to continue using this company.
