We have maintained our business through customer referrals and repeat service, and we value the relationships that have allowed us to serve the community for so many years. Residential plumbing remains an important part of our work, and we provide solutions for water heaters, bathrooms, drains, garbage disposals, water filtration, hydrojetting, and French drain systems. Our goal is to handle plumbing jobs of every size with reliable service.

For water heater replacement, we handle tank and tankless systems and provide code-compliant installation supported by manufacturer-trained credentials. A comparable tank replacement can be completed quickly, with less annual maintenance and a lower installation cost. Tankless alternatives use less space, deliver endless hot water, and can provide energy savings through improved efficiency.
Sullivan Plumbing provides sewage pump maintenance intended to keep pumps operating reliably and efficiently over time. For each maintenance service, we test amperage, assess the float tree, and inspect the basin seal. We then test the high-level alarm, examine the cutter blades for damage or foreign material, and remove soap or grease buildup as needed.
Plumbing emergencies can occur at any hour, so we maintain 24/7 emergency response for our customers. When you call, a live person is available to coordinate dispatch of a plumber as quickly as possible. Our team is equipped for numerous urgent repairs, and fully stocked trucks help us avoid delays from additional supply trips.
We provide sewer line solutions for properties experiencing recurring drainage problems, sewage odors, water backups, unusual yard growth, or gurgling drains and toilets. These conditions can indicate an underlying blockage or damaged pipe. After assessing the system, we determine whether repair or replacement is needed and use methods intended to minimize disruption to the property.
We specialize in main water line installation and repair, providing solutions for new homes, aging systems, and unexpected line breaks. Depending on the circumstances, our team may use traditional excavation or trenchless repair methods, including pipe bursting and pipe lining. We consider the extent of damage, pipe material, soil conditions, and budget before recommending the appropriate approach.
We specialize in upgrading aging residential plumbing through complete whole house repiping. Older pipes may corrode, collect mineral deposits, become brittle, or develop recurring leaks over time. Our process includes a detailed assessment, material selection, professional installation, post-installation inspection, and cleanup, helping establish consistent water flow while addressing problems associated with failing plumbing.
Our professional leak detection and repair service focuses on protecting the functionality and safety of your plumbing system. We use accurate, non-invasive techniques to find hidden leaks and determine their source. From minor pipe patching to extensive re-piping, our plumbers provide appropriate repairs, confirm successful results through testing, clean the work area, and offer preventative advice.
Our professional gas line service combines installation, repair, leak detection, and system assessment for residential needs. We connect new gas appliances, address worn or inadequate lines, and respond to suspected leaks using advanced detection equipment. Throughout the project, we follow local regulations, manage required permits, provide clear estimates, and test the finished work carefully. 2025: Sullivan Plumbing saved the day again. They were able to come out quickly when a hot water heater started leaking and not only fixed the issue, but made it better! Kody and Dwayne were very friendly and helpful - and the dog loved them too. Customers for life!
The pricing was fair and reasonable, and the entire experience exceeded our expectations. I highly recommend the incredible team at Sullivan Plumbing without hesitation. Five stars!

Nice, energetic and capable young men, great at explaining and the whole nightmare was taken care of within 5 hours.
It was a helluva way to wake up but a great day overall.
We'd never had to use an emergency plumber and hope we don't have to call again but IF WE DO, Sullivan Plumbing is our go-to.
(When we mentioned it to a neighbor they said that Sullivan recently went through an owner change and that many of the older crew took retirement at that juncture). THANKS GUYS!!
We had a complex plumbing problem arise in a home that houses a young family with 3 kids under the age of 10 - and only one bathroom. Don took us under his wing and saw us through every aspect, coming up with solutions that were rock solid (and creative!) that we feel very confident in.
He was very easy to communicate with, calm, knowledgable, and presented us with options all along the way that took many factors into consideration. He and his team were there when they said they'd be there and worked efficiently. They were mindful of noise, disruption to daily lives and schedules, cost, and came up with designs that were both cost effective and result in easier and more effective maintenance moving forward.
He made sure every step of the way that we were given opportunity to ask questions and be part of the decision making process. He also was welcoming of our desire to inspect the work in progress and made sure we were satisfied with every aspect. Who does that anymore?? It kind of blew us away. If we had questions, he took time to explain.
We had a lot of opportunity to interact with the office staff - and they were fantastic as well! We found each person to be friendly; their communication and responsiveness were first rate.
I cannot say that we look forward to any more plumbing problems, but I can say with all honesty, that we feel very confident in knowing who to call when the next time comes. Cant say enough good about Don and his team. They were lifesavers.
