They replaced our water heater and installed some new venting and water piping. Also, new valves. Julian was great at what he did as well as being a very nice person. The... company was somewhat pricey though, as I was charged $4,287.00 for the new equipment and installation. Also, I wasn’t given an itemized receipt, although I was told I could call the company and ask for one.read more
