"I hired this company to extend the natural gas in my house and would definitely recommend them. I felt that the plumber who did the installation really knew what he was doing and seemed like a great guy. The installation went well and the price was fair."

"Mayo plumbing is amazing! We called John for a leak from our main water line in our basement. He rearranged his schedule to fit us in & didn’t leave until the job was done. He was able to fix the leak with a less invasive method than what another plumbing company we had already contacted quoted us. Many thanks to John! If we ever need plumbing work again, he will be our only call!"

"Got back to me quickly, fixed the issue with my hot water heater rather than having to buy a new one, very thankful. He checked out my heater and air conditioner while he was there and I will have him back to service my AC. Great guy, very friendly, took the time to explain all he was doing. Highly recommend him."
