Services
Water Heater Services Professional water heater replacement is available for homes using either tank or tankless systems. Our technicians provide code-compliant installation and take the time to explain the benefits and considerations associated with each choice. A tank heater can be replaced quickly when using a comparable unit, while a tankless heater can provide endless hot water and improved efficiency.
Sewage Pump Service Sullivan Plumbing performs maintenance programs on every size and style of sewage pump, helping maintain longevity, reliability, and efficiency. Our technician checks amperage to identify wear or partial blockage, tests pump cycling through the float tree, and examines basin sealing. The service also includes alarm testing, cutter blade inspection, and removal of buildup.
Emergency Plumbing Service We provide emergency plumbing assistance around the clock, including nights, weekends, and holidays. When you contact us, a live person answers and quickly dispatches an emergency plumber. Our trained team takes every plumbing issue seriously and works to resolve urgent problems as soon as possible, helping restore your plumbing with minimal delay.
Sewer Line Services We offer comprehensive solutions for damaged or failing sewer lines, with the goal of restoring proper wastewater flow and protecting the property. Multiple slow drains, recurring toilet backups, sewage odors, wet lawn areas, and gurgling fixtures may indicate a sewer problem. Our experienced team uses suitable repair or replacement methods based on the condition.
Main Water Lines A properly functioning main water line is essential to maintaining dependable water service throughout your household. We offer professional installation, repair, and replacement for main water lines affected by leaks, blockages, corrosion, or breaks. Our team can evaluate warning signs such as reduced pressure, rising water bills, discolored water, wet areas, unusual sounds, and foundation concerns.
House Repiping Service Our team provides complete whole house repiping for residential plumbing systems showing signs of age or failure. Problems such as brown or reddish water, reduced pressure, repeated leaks, outdated galvanized steel, lead, or polybutylene piping may indicate the need for replacement. We assess the system, help select appropriate materials, install the new piping, test connections, and restore the work area.
Water Leak Detection Our leak detection and repair services address both subtle and significant plumbing leaks with careful attention to accuracy and lasting results. Specialized equipment helps us locate concealed water intrusion without unnecessary damage. Once the source is established, our plumbers select the appropriate repair, complete the work efficiently, test the plumbing system, and share prevention recommendations.
Gas Line Service We approach every gas line project with safety and precision as priorities. Whether an existing line needs repair, an appliance requires a new connection, or an older system may need an upgrade, we first inspect the current setup and discuss your needs. We then provide an upfront estimate, secure required permits, complete the work, and test the lines.

Our family (of moderate income) has called on Sullivan Plumbing for many years to help us with various jobs. We love working with Sullivan and have never been sorry. It is very comforting to know that they have always been right there for us in an emergency.Amy in the office is caring and sets up help for us right away. Kody Prosser is usually the one to help us. He has worked with us on big jobs and small ones. He is conscientious about researching to find us the best value and product and he is an expert plumber. We have never had any problems after he has finished a job. Kody usually brings Johnny to assist. They both are a pleasure to know - and our cats like them, too!

2022: Everyone we worked with was incredibly professional and kind. Don took the time to educate us on plumbing and fully explain our system. He gave us options with estimates at every step. Ended the day with a quick fix and a clear long term plan. HIGHLY recommend this wonderful company.

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!

we had a great experience. Chris at Sullivan diagnosed the problem with my mom's tankless water heater but just to confirm he faced timed with the factory rep while on site and they confirmed his diagnosis. Once the part arrived, Chris got the unit up and running and the total cost was less than the estimate if you can believe that. Knowledgeable, efficient and honest describes our experience with Sullivan.

Chris and John came out, identified a leak and told me how they were going to fix it, how long it would take and quoted me the price, two hours later, leak fixed, no mess left behind and the cost came in u der the original quote. HONEST company, great service and honorable employees.

Hope I never need them again but, if I do I know who I'm calling.

Great company and Service!

I recently had a great experience with the team at Sullivan Plumbing. I was in need of a professional water heater installation and they exceeded my expectations. From the initial call to the final inspection, their communication was top-notch.
It is hard to find fair pricing and honest service these days, but they provided a clear, upfront quote with no hidden fees. The technician was punctual, respectful of my home, and clearly highly skilled. If you are looking for a reliable plumber in Bellingham who does quality work at a reasonable rate, I cannot recommend them enough!

I am a manager at a complex here in Bellingham. We met Kody Through Sullivan plumbing years ago when we had an emergency in the middle of the night and out of many phone calls to other companies Kody with Sullivan plumbing was the one that came through for us. His knowledge, efficiency, and wonderful demeanor Combined with fair pricing has made us comfortable calling Sullivan to have Kody come out to do a wide range of projects for us over the years including our regular check, ups of scoping and auguring out our main lines, along with multiple shower, replacements drainage, plumbing repairs around the property like angle stops and water heater shut off the list goes on! We are so glad to have Kody and Sullivan Plumbing on our side when it comes to our plumbing needs 5 s 100 times over

Duane saved our Christmas! Major clog in the sink occurred Christmas morning and he was there that afternoon to do the repair. He was very sweet, did the repair quickly and left the area under the sink super clean. We were able to make Christmas dinner and clean up all the dishes in the sink like nothing ever happened. We have used Sullivan in the past and will continue to do so for all of our plumbing needs!

We now feel like we have a reliable plumber. What a relief! We had our kitchen plumbed for a high-end steam oven we were installing. It required a cold water feed and a waste water drain for steam condensate. Our technician Nick was not familiar with the appliance (few people are!) but familiarized himself with it online ahead of time, and was certainly knowledgeable and competent in the tasks required, and practical in his approach to adapting the installation to our kitchen. They were able to schedule us quickly, and took excellent care of our floors, cabinetry, and clean-up. The system is now working flawlessly. He quoted me a reasonable hourly rate plus parts, and the total came in within the range he had guesstimated at the outset. We are very happy with Nick and with Sullivan Plumbing.

Nick from Sullivans Plumbing was super great to work with. His gentle demeanor was so pleasant while I was frantically in need of someone to run a sewer scope on a home I was trying to buy, so I had little time and needed it done asap. I had called several plumbers and no one who was certified was able to get to the home in the quick timeline I needed. He tried to do it in a way that would save me a little bit of money, but he was up front about the costs as we moved along. By end of day, I had a recording of the scope and a full write up. The gal that set up the appointment was super helpful and kind as well. I know who I will be calling next time I need a plumber! Thanks Sullivans!

Had to replace a faucet in our laundry room. We bought a new Delta pull out faucet rather than repair the existing hose and Sullivan did the install. Appointments were scheduled promptly and the plumber (Scott) was very professional. Wouldn't hesitate to call on then again.

Their staff are responsive, friendly, professional, knowledgeable and all their work has been the best. We've called Sullivan Plumbing several times since buying our vintage house. From finding the source of a smell, to fixing the problem, new installations, recommendations for products and solutions, correcting non- plumbers attempts at installs and repairs - we have been completely happy with their work. They respect our home and our cats, and we will definitely continue to call them with all our plumbing needs. We still have a kitchen remodel to go!

Nick and Chris to save the day! I woke up to a dead hot water tank that was now leaking everywhere. I called at 10:00 am. They were at my house with a new tank by 11:30, and finished and gone by 3:15pm. Clean, curtious, worked super hard, and honestly left zero trace of them even being there. Great guys and I fully recommend this company to help you out in a crisis.

We woke up to a strange noise in one part of our house. Husband found that our crawl space was Niagara Falls. We tried to shut the water off at the street, couldn't find it. Called several places but Sullivan came first and FAST. First guy came, dug A LOT MORE THAN USUAL to find our key shut off and shut it off. He left, next guy came and took care of the problem. We were doomsdaying the cost of the whole operation including a section of rotted pipe replacement, new shutoff valve and the emergency service. It wasn't even near the amount I was fearing.
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!!

Plumbing issues are NEVER fun, but we feel very fortunate to have met Don Dawson in the midst of a doozy. He is a good and decent human and that goes a LONG ways in our book. And he has assembled a great team as well.

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.
