We needed A LOT of major work done with the water filtration and septic systems. The two plumbers, Johnny and Michael, aka, "Mo", were very professional, knowledgeable, good natured and extremely hard working. The work was dirty and involved removing and then installing large, heavy tanks, pipes, etc., using equally large and heavy tools. They worked CONSTANTLY and were very conscientious in their attention to detail. Yet, they graciously and courteously answered questions and explained what they were doing and why. They were very, very impressive and there's no doubt they did the work correctly. We feel confident that we won't have to call them back to re-do anything. It's obvious that plumbing is in their blood. They're great!
