"Plumber charged a lot to hack up my house to fix a leaking pipe behind the dishwasher. He didn't hook up the dishwasher drain line correctly and it leaked. Had to fix myself. They used a scrap pipe instead of the proper $2 part. They wanted to charge me a service fee to come out and fix their problem. I would give zero stars if I could. Over $2200 for bad work. Avoid these guys!"
