My water heater was leaking and I called another plumbing company first. They came and gave me an estimate and they wanted $1,500 to replace my 50 gallon water heater. I called CSI Plumbing and they asked me some questions over the phone and gave me a quote that was seven hundred dollars less. I had them come out and the price didn't change. They did a wonderful job. I will only use CSI Plumbing from now on.
