"Responded immediately to the side effects of a water break in the house. Immediately restored electrical services to dry areas, came back a few days later to restore more services. Gave detailed proposal before work was initiated, had enough supplies on truck to immediately replace most of affected parts. and advised on purchase of replacement fixtures. The technician was cheerful and understood my goals in restoring service."

He has installed appliances such as dishwashers, washer and dryers, garbage disposals, faucets and sinks, a hot water heater, and a gas boiler. He is very trustworthy and knowledgeable about what he does and stands by his work. If there is an issue, he will get back to you and fix it in a timely manner. His pricing is reasonable and he does excellent work. I would recommend anyone to use him."

"They had to dig out and replace a section of the cast iron drain out through the fieldstone foundation of my house and added an exterior access clean-out. They came on time, were courteous, did a fine job, and cleaned up afterwards. They also charged me less than the estimate! I was very pleased... I couldn’t 't ask for better."

"Replied quickly, had lowest quoted price (significantly lower than my other quotes), did a really nice Roth tank installation in a tough spot, did NOT price gouge me for some extra piping that was needed, on time, cleaned up after work was completed. Solid A rating from me, I would recommend his services if your in need of an oil tank replacement or upgrade."

"All three jobs went great. For the water heater replacement Lewis came to my house at a convenient time for me, removed the heater changed out the rotted pipes and installed a new one with warranty. The price was great too. This job was time sensitive and he made me a priority to get it done. For the bathroom tub drain unclog he was very professional and did a great job. My garbage disposal was leaking and I came home to a pool of water in my cabinet and on the floor. Lewis came out quickly to resolve the issue for me. He replaced everything under the sink and showed me what he was doing each step of the way. I think that he is a great plumber if you want to get quality work and learn about each job too."
