"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!"

"It went well under the circumstances. I found out that day, that my water had been turned off without my knowledge by America Water, which made it impossible to hose down and clean the outdoors unit. They did their part so I was satisfied. It would have been outstanding if they were willing to come back out to complete the cleaning when water was turned back on, for a perhaps half the price ($49.99). They would only come back out for $89.99."
