"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!"

"Sam replaced a water heater that was under an enclosed counter area after removing the old water heater, and replaced a damaged circuit breaker for what seemed to be a very reasonable price. Many difficulties arose that were not anticipated and he handled them all in an extremely professional manner. Definitely someone to keep on my contact list."
