- JBjoe bonaventuraOct 27, 20265.0Steven was my assigned plumber today. He quickly assessed the situation, letting me know that the main pipe needed to be snaked. He clearly explained the work that needed to be done and how much it would cost. Steven was efficient and worked neatly. He was polite and very courteous. I would highly recommend Sullivan Plumbing &Heating. Ask for Steven, if he’s available.
- TMTom MellisJul 9, 20265.0We 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.

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.
- MNMegan NashJun 19, 20265.0I could not ask for a better job that was completed by Steve. I was completely happy with the work that was done. I would recommend Sullivan Plumbing to anyone looking for a plumber.
- KVKevin VenturinoJun 19, 20265.0By far the best experience I’ve ever had with any plumber. Sean and Debby are amazing and go out of their way to make sure whatever you need is solved. They truly go above and beyond. I will only use their services from now on!
