"Our heater stopped working around 7 pm during the night, last Feb 2026. We had no heat for the whole night so it was really cold inside the house the next day. To our relief, Mark was able to come out the very next day in the morning. Mark checked and tested numerous devices on the furnace. He explained everything that he was doing while repairing the furnace. He was here for only an hour and got our heat going again. He's friendly and trustworthy. He is our Plumber and we call him for any problem. His rates are reasonable. We highly recommend him. We live in Brockton 02301."

"The technician arrived later than expected but he explained that there was an emergency that morning and was courteous once he arrived. The tankless water heater was making intermittent noises and a descaling was done. I haven’t heard noises since so hopefully the water heater will last for many more years. The technician said typically lifespan is only 7-10 years which is shorter than the 20 year I have in mind."

"The plumber arrived in the allotted time frame which was terrific as we had a significant storm with trees down & power outage.He assessed the situation developed a plan and secured a water heater & replaced my old one. Very kindly alerted me to another issue that was going on in the basement. I would recommend Matt with out hesitation. Thank you for your seedy response.Katherine Kelliher"
