The two gentlemen who showed up were professional, knowledgeable, and helpful. They took the time to explain the situation to me. Unfortunately, I am still having a problem--not because of the work done, however. I believe that the main problem is in the washing machine, so I will have to take some more steps to solve the problem. I would recommend JL Hearn, though. I was happy with the service and will turn to them again for future plumbing problems.
