"In late June of 2023, Neo and his apprentice replaced our water heater. Neo did charge slightly more than Google reported as the average price in our geographic area. However, "you get what you pay for." Neo was diligent, friendly, efficient, and knowledgeable. Neo responded promptly to all telephone calls and text messages. There was no drama with Neo. Neo was a consummate professional. We would definitely recommend S&S Piping and Heat. When we experienced a runaway faucet and a broken shut-off valve in the spring of 2024, Neo was quick to respond. Our over-engineered faucet required more than the replacement of a simple washer. In a professional manner, Neo repaired the faucet, replaced the valve, and corrected a related water-pressure problem. As usual, Neo offered good, solid communications. Yet again, we would definitely recommend S&S Piping and Heat."

"This is my sixth time using the service from Andrew at Local Plumbing and Heating. He is quickly available, efficient and thoughtful. He is trustworthy: I know he will take care of everything I asked for and thinking ahead for great ideas. I used his service for major home projects and I strongly recommend him for everything: from water heater tank replacement to gas lines installations."

"Hello Everyone! I'd like to give Milltown a shout out for installing our new HTP Combo unit. I'd like to especially thank Garret, Brandon, and Kat for pulling the whole thing together and making the installation as seamless as possible. Also, shout out to HTP for replacing a defective unit. They stood up and did the right thing when they didn't have to. Milltown went above and beyond what a plumbing company would typically do. When our combo unit failed, we lost heat and hot water. Milltown was able to hook up a temporary hot water tank so my family had access to heated water for showering, dishes, etc. Everyone I spoke to were genuinely concerned and could not have been more professional in their workmanship, cleanliness, and finished product. I am very pleased with everything from start to finish."

"Justin and Cam, the technicians, did a great job. We have an old farmhouse with a very strange configuration of partial crawlspace and partial full basement, and water was leaking through the fieldstone foundation wall from the crawlspace. They quickly diagnosed that the problem was coming from 1 or 2 zones of the hot water radiator heating system, and they were able to shut off those zones to stop the leak, while allowing the house to still use water for sinks, toilets, and showers. We'll have to do more work later to replace pipes to the radiator but, because they are hard to access, we need to plan ahead for some construction work. I'm fully satisfied that these guys were able to find the problem and give us even a temporary solution that allows us to have our working plumbing again without the basement getting wet. Would definitely work with them again."
