Quality Plumbing, LLC says on its website that it does plumbing repair across the Seacoast region and Southern NH. Its New Hampshire plumber license, number MBE2401625, is active on the state registry under the company's name. Google shows a 4.9-star rating from 45 ratings. A recent customer said Ken completed a total repipe on their manufactured home in just a few days, and that the inspection he scheduled passed. A recent customer referred by a friend to Ken Hilton had a shower/tub combination converted to a walk-in shower, with his carpenter Rich assisting. A recent customer said Ken assessed their plumbing issue, presented several options and completed the work at a reasonable price. A 2026 customer said Ken came out for a second opinion after another plumbing company tried to convince them to do work that wasn't needed, and that he caught a leak the other company missed. A 2025 customer wrote that Ken replaced old corroded copper with new PEX pipe and valves for all the incoming water, and also did the outside faucets and a fix to a main drain line. A 2024 customer with a rental property said Ken installed a 75-gallon water heater, a whole-house sediment filter and an auto shutoff valve, and replaced a broken sewage ejector pump.
Making an appointment with Quality Plumbing was easy, and the response was prompt. Good communications. The needed work was done professionally and thoroughly.
Ken is great. Very communicative, clearly knows his stuff. I would definitely recommend Quality Plumbing!
Ken showed up early and did a great job. He goes out of his way to keep your house clean!
Ken at Quality Plumbing was professional from start to end. He assessed our plumbing issue, described the concern so we could understand, and presented several options. He then completed the work we needed in a timely manner and at a reasonable price.
Ken was professional and extremely knowledgeable. He suggested a solution to my problem and gave me a reasonable solution at a fair price. The condensation drain line from our forced Hot air heater and AC had originally been installed in a very flimsy manner, by hanging the end of the drain hose from the condensation unit in an open PVC pipe under the kitchen sink. It occasionally popped out and soaked the inside of the cabinet and floor. He placed shoe protectors on when entering the house, and brought drop cloths to prevent making a mess. He had the necessary parts with him, and performed the work. When he was finished he tested the system, and gave a detailed explanation of the solution, as well as telling me to feel free to contact him with any questions or issues. Finally, he cleaned up thoroughly before leaving, including taking all the old PVC he had removed. I would highly recommend him based upon him responding to my request the same, and addressing the issue the next day, in addition to his outstanding work.
