Very Expensive... They are fast, nice, and real plumbers but it will really cost you. I had a valve replaced in a hot water heater and it cost almost $500. The part was about $160 and the labor was over $300. He worked on it for less than an hour. I asked him about his rates and he said that he counted the drive time to get the part and return the old part. I then asked how much an hour and he said he gets paid per job. I feel like the price is probably higher depending on how desperate you are. I would shop around for prices if possible.
