I give PipeTechs high marks. We had an underground water leak.(This is one of their specialties.) Their tech quy came out, we surveyed the problem, made a determination of where the leak was. He then proposed the least-expensive way treating the problem, which was to lay a new line coming into the house at a different spot. They insulated the line, contacted the city inspector, and returned very soon after the inspection was complete. They were prompt and easy to deal with. They replanted grass when they were finished and even hauled away some tree roots they had to dig up. All this for what we thought was a very reasonable price. I would certainly deal with them again.
