I have used Guardian Plumbers before, but it has been about a year, and I was quite surprised that the prices I was charged this year for a similar job were so much more than the prices I was charged last year. Last year, I had a faucet installed in my bathroom, and it cost about $150. This year, I had a kitchen faucet installed, and it cost $250. Overall, the entire job cost about $450 this, and I just thought that was a little expensive. Also, the person at the office said one guy was coming, but that wasn't the person who actually showed up. There were two guys that showed up, and one of them seemed to be in training. He installed the toilet seat, and the other guy did all of the actual plumbing work. He installed the kitchen faucet, and he also installed the handle in the interior part of the toilet. They did do a good job and everything is working properly, and I would recommend Guardian Plumbers, but I would also say that they can be a little pricey!
