    "As part of a major kitchen renovation I hired Harry to do a complete re-pipe of the all the gas lines in the house. This included increasing the pipe sizes from 3/4" to 1" and 1/2" to 3/4" to provide proper gas pressure to the new and existing appliances. He also installed a seismic shutoff valve that was required by the building inspection department. Harry knows his stuff and was easy to work with. He did a good job and completed it on time. I'm very satisfied with the quality and the price of his work and I will gladly recommend him."
