"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."

"My grandson flushed his little yellow bus down the toilet Friday afternoon. I called several plumbers in the area. By late Saturday afternoon I had only 1 returned call saying they could come out Monday morning. A friend suggested I call Gentille Plumbing and Heating. I called them and they said they could come early Sunday morning. Ryan arrived promptly as promise and quickly determine how to approach the issue and retrieved the little yellow bus. Cleanup was quick and pricing fair. Ryan was professional , friendly and was on his way within 45 minutes of arrival. Thank You Gentille Plumbing and Heating"

"Boston Plumbing and Heating Solutions responded immediately and was able to come to my house within an hour and fixed the leak. They were courteous and cleaned up after they were done. I would hire again."

"Our gas water heater failed on a Friday night. Waking up Saturday a.m. to water in our basement wasn't a pleasant experience. We placed several calls and Quarry Hills was the only company to return our call. Michelle was very helpful with locating the same water heater within a short time frame as the gas heater that failed was still under warranty, to our surprise. She promptly scheduled a tech to our house by 1 p.m. the same day with the new water heater in tow. Seth was very knowledgeable and worked efficiently to get us back up and running. They were straight up with the cost and didn't exceed it when finished with the job. Rebecca followed up with a call to check in on our experience with Quarry and confirmed that they'd forward any warranty information upon receipt. Very professional from start to finish! We won't hesitate using them again for any future issues we may have."

"Can't say enough good things about Whalen Plumbing and Heating. Our tankless water heater was giving us inconsistent temperatures and error codes, and they made the fix painless. They showed up on time, asked what we'd noticed before touching anything, and clearly know these units inside and out. They flushed and descaled the heat exchanger, cleaned the inlet filter, and checked the venting and connections, explaining everything in plain English with no pressure to upsell. They were respectful of our home and left the area cleaner than they found it. Pricing was fair and matched the quote exactly. Since the visit, our hot water has been steady and the unit runs quieter than it has in a long time."
