“Ivan did an outstanding job in installing a pressure regulator valve. This was a new install, not a replacement. So Ivan had to come up with a new design to fit within some space restraints. Excellent job. Very professional. We now have our go-to plumber for any future work!”

Effective and Efficient Plumbing and Drain Cleaning Services

“My kitchen sink decided to clog up on the weekend. Ivan was able to provide a quote and come out within two hours. Not only did he clear the drain in a jiffy, but he also found a tiny leak in my p-trap. It turns out the pipe wall was badly corroded, and I never noticed. Thank goodness he had spare parts and was able to replace the pipes. He was very courteous and knowledgeable. The price seems pretty reasonable. Not the cheapest, but I would rather pay more, so I don’t have to wash dishes in my bathroom for another day. Knock on wood, I won’t need a plumber for a while, but I’ll be sure to contact him again if the need arises.”
