"We had broken underground pipes that flooded ours and attached neighbors houses. We have a shared meter, with neighbors having their own shutoff, we did not. After 3 quotes, we felt most confident in Harry. He installed a shutoff valve for us, and now neighbors and us are not dependent on each other’s water. He then isolated and replaced the damaged pipes. He was able to do this without further damage to the house. He came in less than verbal quote and never tried to upsell, which was an issue with one of the other companies. We are very happy with Harry’s work, would highly recommend him."
