Services
Water Heater Services We offer water heater replacement services for tank and tankless systems, backed by manufacturer-trained expertise. Our technicians first assess your hot water needs and then explain the available choices and considerations. Depending on your priorities, a tank system may provide faster comparable replacement, whereas a tankless unit can save space, energy, and offer continuous hot water.
Sewage Pump Service Our sewage pump maintenance program addresses the components that contribute to dependable wastewater system performance. We test the pump amperage for signs of wear or partial blockage and confirm proper cycling through the float tree. Basin sealing is reviewed, the alarm system is tested, cutter blades are checked, and accumulated soap or grease is removed.
Emergency Plumbing Service When a plumbing emergency occurs, our team is ready to respond day or night, including weekends and holidays. We answer calls with a live person and send an emergency plumber into action quickly. Our fully stocked trucks carry extensive supplies, allowing us to address many urgent plumbing problems without unnecessary supply runs.
Sewer Line Services Our team delivers dependable sewer line repair and replacement for plumbing systems affected by deterioration, blockage, leaks, or structural problems. We consider the condition and location of the damaged piping when selecting a service method. Trenchless techniques may provide a cleaner, faster alternative, while traditional excavation is performed carefully when it is necessary.
Main Water Lines Reliable main water line performance supports a consistent supply of fresh water throughout your home. We provide installation, repair, and replacement services for main lines, including solutions for leaks and breaks. Traditional excavation is available when necessary, while trenchless techniques can reduce disruption to landscaping. Our recommendations are based on the specific condition of the existing line.
House Repiping Service We deliver whole house repiping services focused on replacing aging plumbing with a dependable new system. Our work starts with a thorough inspection to determine pipe condition and identify areas requiring attention. Homeowners can choose between PEX and copper based on their needs and budget, while our plumbers manage installation, testing, inspection, and cleanup from start to finish.
Water Leak Detection We provide a professional process for identifying and resolving plumbing leaks. First, our team determines the leak location and evaluates the damage. We then explain the recommended repairs and provide a detailed estimate before work begins. Quality materials and proven methods are used for the repair, followed by system testing, workspace cleanup, and preventative guidance.
Gas Line Service Our technicians provide reliable gas line solutions for homeowners who need installation, repair, or system improvements. New appliance connections are carefully planned, properly sized, and pressure tested for secure operation. For suspected leaks, we use advanced detection equipment to locate the source and complete prompt repairs while maintaining required safety standards and regulations.

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 leak we could hear but couldn't see, and Sullivan Plumbing came to the rescue. Megan booked us for a service call the very next day, and Chris and Casey were outstanding. They were professional, friendly, and quickly identified and repaired the broken pipeall within an hour.

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!

My sewer line had a root ball causing a back up into the house. Sullivan responded the same day I called and tried all they could to get the problem cleared from removing my toilet. Unfortunately it could not done. They put in a sewer line clean out and got the root ball cleared out and my line flowing again. They did it all in a timely manner. I can't complain about the price as everything is expensive now days. If I have to call a plumber again SULLIVAN is my first call.

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!

They showed up on time and diagnosed my issue quickly. The problem was resolved so quickly that I was only charged their show up fee.

Kody and Casey fixed my leaking tub faucet. They were knowledgeable, communicative, friendly, clean, and efficient. This is the second time I've hired Sullivan Plumbing and have been pleased both times with the staff and the work. Both times I have felt comfortable with them in my home, which is important to me as a single mom. I don't know how much plumbing jobs typically cost, but the price seemed very reasonable and pricing was upfront.

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

Pete and team are the best plumbers in Bellingham. I live in the county and have a weird storm drain that was flooding late at night. Pete showed up fast, unplugged the drain and prevented my ADA ramp from flooding worse. On a separate occasion, Sulivans did an expert and very fairly priced heat pump water heater install. I appreciate their fair and transparent pricing.

Nick from Sullivan plumbing helped us fix our leaking toilet. Next day service, friendly, and professional. Well worth the investment to install a flange, fix the piping, and properly install the new toilet. The bathroom was left cleaner than when he arrived and the attention to detail with the added caulking was unexpected. I will be using their service again.

Nick and Johnie did a great job of installing our dishwasher and range. The range was converted to propane from Natural gas. They took the time to ensure that everything was working as per specs and kept me informed along the way. Thanks

We had a pretty good experience using Sullivan. Our water heater went out on a Friday and Kody installed a new one on Saturday. He was extremely patient and friendly - even measuring the dimensions of his truck for a curious neighbor. Not the first time utilizing Sullivan's services and won't be the last.

Full disclosure: I didnt winterize my outdoor spigot. Is that what I told my wife? No. Did I try to fix it myself and further damage my house and marriage? No. I called a professional, Kody, at Sullivan Plumbing.

Not only did he crawl through my crawl space, but he was fast, professional, and did a great job. He also didnt tattle on me to my wife. It was a old spigot. When I inevitably mess up my house again, Kody will be the first call.

Had a great experience with Sullivan Plumbing! Keep up the great work.

Nick of Sullivan Plumbing quickly found the blockage in our sewer line and cleared it. We're sold on Sullivan Plumbing since 2 months ago a competitor scoped our sewer line and told us that everything was clear. Nick showed us where the roots were in our line and proposed a permanent solution which we are currently evaluating.

Kody Prosser was our lifesaver! Our dishwasher we bought was never installed properly and developed a leak. Kody came over and fixed it for us. He was incredibly nice, efficient and absolutely knows what he is doing! Thank you again!

Scott and the assistant quickly saved the day and fixed our toilet . Both men were very friendly. They did a great job and left the bathroom clean and tidy. We were glad Sullivan was as quick as they were.

We needed a sewer inspection done on a potential home we wanted to buy, Kody came out and walked us through the entire inspection so we knew exactly what we were getting into with buying and remodeling such an old home. He gave us lots of good advice and offered services for the future! He was so easy to work with and very knowledgeable!

Highly, Highly recommend Sullivan Plumbing! Nick got our vacation back on track! Visiting WA on holiday, we experienced a leaking pipe that caused the water to be shut off until a fix could happen. Sullivan came to the rescue, arriving asap. Nick drove out to our location, quickly diagnosed the issue, and got to work! He completely fixed our problem, flushed the system, and turned the water back on. NO MORE FLOODING!!! Couldn't have gone more smoothly. Thank you Sullivan Plumbing.

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.
