Great price in Oct 2025 I called Sullivan Plumbing & I received a prompt call back to set up an appointment. George was courteous & gave a fair price to install a kitchen faucet. It was done in an hour and the area cleaned up before he let. I would recommend Sullivan Plumbing to everyone! Joanne A Services Faucet installation

We recently moved into our new home and needed a plumber for several tasks, most importantly replacing our 26-year-old gas water heater. We wanted a company that was prompt, responsive, courteous, able to spot issues we hadn’t considered, and fair on price. After contacting a few vendors, we chose Sullivan Plumbing and Heating — and it was a fantastic choice. From start to finish, Sean Sullivan and his team, both on-site and in the office, exceeded our expectations. In addition to installing the new water heater, they performed a gas leak test, removed decommissioned pipes, installed a Moen Flo water monitoring device, added a backflow system for our irrigation, replaced bathroom faucets, installed a metal washing machine pan, and fixed the internal components in our toilets so the tanks filled properly. The work took about two and a half days. Sean and his team were courteous and diligent, addressing concerns promptly and offering practical advice that helped us make good decisions along the way. I highly recommend Sullivan Plumbing and Heating — they’re now our go-to team for all plumbing and heating needs.

I couldn't be happier with my experience with Sullivan Plumbing & Heating. From my very first phone call, Sean and Debbie were an absolute pleasure to work with-friendly, knowledgeable, responsive, and genuinely committed to providing outstanding customer service. The installation of my new water heater was flawless. The technicians arrived on time, were courteous, professional, and clearly took pride in their work. They treated my home with the utmost respect, kept the work area clean, and completed the installation efficiently while answering all of my questions. In today's world, it's refreshing to find a company that values professionalism, quality workmanship, and exceptional customer service from start to finish. Sullivan Plumbing & Heating exceeded every expectation. If you're looking for an honest, reliable, and highly skilled plumbing and heating company, look no further. Sullivan Plumbing & Heating is truly top-notch, and they've earned my highest recommendation.

Great price You know how you wish you just had a good Family Plumber - one you can rely on and trust implicitly. Well meet my new family plumber. Replaced my Gas Water heater for a fair price. Responded the same day to evaluate and quote the job - and was promptly out the next day with all equipment for the install. Seems like everyone from the owner Sean, the office staff, and tthe two youthful plumbers he sent - were just so pleasant to deal with. Installers donned little booty's to protect my floors and carpets - a real class act. So incredibly satisfied with the outcome of this project. Highty Recommended! Services Water heater installation

Great price Superb Professional Service! Had a big project with main sewage line replacement. The Sullivan Plumbing was recommended to us by our contractor who did prior work in our house. From the start to the end, they were professional, patient, super clean, and reasonably priced. First call was with a very friendly receptionist who scheduled an initial assessment. Steve has arrived on time as scheduled, was very professional, took his time and explained everything. He did camera inspection and didn’t rush. Put all back in place and cleaned afterwards and worked with the company to provide outlined work order and very reasonable price. Work started the next day, again right on the dot at 8am as scheduled. The team covered the areas for cleanliness and were very professional. We did hit couple of questionable areas of concern as with any large project (mostly due to us being anxious homeowners looking at major work happening). Sean, the owner, came literally 10 min later after we called the office with questions, and Steve who did initial inspection came right away as well to follow up with camera and plan of action. Steve and Sean assisted the other 2 workers (who were excellent in doing their work) to expedite things. However, most importantly, Sean and Steve elevated all our concerns and reassured us that all will be taken care of. Work completed on time and homeowners kept their sanity! Sean’s team cleaned all areas of construction material and dirt after replacing the pipe and redoing concreate. Super clean! The responsiveness and true care for the client, coupled with professional and reasonably priced service, really makes Sullivan Plumbing stand out. Would definitely recommend!

Great price Had a great experience with Sullivan Plumbing! Steve came by to help us out with a few small jobs that were accumulating over time. Between working with a Delta Shower Faucet that was half-falling off as well as low water pressure, to working on an non-name-brand shower system from Amazon and replacing the cartridges, check valves, and thermostatic valves, everything worked right the first time. Fixed two toilets which were running without being flushed, and also helped adjust a faucet with high pressure. He was polite, arrived a few minutes before schedule, and worked non-stop the entire time. He brought in drop cloths to keep the floor clean when he went into the crawlspace to turn off the master water valve, which had some dampness due to a lot of rain lately. He wore booties throughout the house without even being asked. He answered all my questions and showed me the worn items he was replacing. I filled out their form online and they called me back quickly to learn about my work and make an appointment. Their hours were flexible and was perfect for us to be home -- there was no "showing up between 8 and 5" timeframe, it was a specific two hour window. I was ready for someone to come and show up, and give a pie-in-the-sky number and I would reject. The estimate was fair, the work was spectacular, and would certainly hire them again!

I am so happy that I went with Sullivan Plumbing. Sean and Steven showed up on time, were extremely professional, and did an incredible job. I have lived in this house for 20 years, and never had very hot water. When the plumber left, I turned on the hot water, and it was steaming hot. I am beyond thrilled, and will recommend Sullivans plumbing to everyone. Services Water heater installation
