"I had a leak in a pipe in the radiant heating pipes in the slab under my house. James was able to isolate the leak and re plumb my system without cutting a hole in the slab. He and his crew did some great creative plumbing that took care of the leak and separated the unused radiant system from my household plumbing and they even installed a new tankless heater in a single days work.. I recommend James and Bowen Plumbing without reservation. They are the Best!"

"They are family owned and operated. Jorge was very friendly and professional, and did everything to help. They even moved the tops of the tanks that must have been over a hundred pounds to a different location and installed Risers. We had to find where the septic tanks were, and what type of tanks, and what was needed to bring the tanks up to code. So we can sell the property. We would recommend them to anyone."
