"Had an excellent experience. He replaced my boiler and water heater and did a flawless job from start to finish. Super professional, showed up on time, explained everything clearly, and the work was clean and efficient. The new system runs perfectly, and the installation looks great. Pricing was fair and there were no surprises. It’s hard to find tradespeople this reliable—highly recommend and would 100% use him again."

"Billy and his are absolutely professional and great to work with. We reported issues with our hot water heater. Billy came over on Easter Sunday morning to investigate. The following day, him and his team came and changed the heating elements. He treated us as top priority customers. I recommend him and his team for your piping needs!"

"For years I have wanted to update my very old and inefficient American Standard cast iron boiler. I was very fortunate to find Mr Joe Burriesci the owner of Mayjac Plumbing who took the time to evaluate the best options, since the old boiler handled two apartments. We collectively decided to go with two Navien Combi Condensing Boilers, but the best part of the entire process was how meticulous the installation was done. From start to finish Mayjac Plumbing kept every promise and timeline made. I highly recommend Mayjac Plumbing..."
