"Great service! Very responsive, this guy should be the standard with how all sub-contractors work - giving his profession a good name! The price was a bit high BUT given the responsiveness and communication before and after the job, I think you pay for quality. There was ZERO stress working with this plumber. You should do some pluming work just so you can see how awesome it can be. But seriously, timely, respectful, and called/emailed what was going on, good service."
