"I needed two boilers and a hot water heater replaced. Billy and his crew did a beautiful job, everything done perfectly, neatly and quickly. I was very impressed. His fees are reasonable, no ripoff. This is a definite five plus stars. Highly recommended ."

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"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..."

"This was the second time using South Shore Plumbing & Heating they installed a tankless water heater for me in March. 2020 and today Nick located and fixed a pin hole pipe leak under my house cement slab. From the time Nick started to make his first cut in my Sheetrock he used a level to make sure he was cutting a straight line ( thatâ s a professional who take pride in his work) when he drilled to open up my slab he made a small hole that was right where the pipe leak was. Cut out the bad pipe and installed new section of pipe no leaks and Nick re- cemented the hole closed and clean up all the debris. Anyone who needs excellent plumbing or heating call South Shore Plumbing and Heating ."
