Sullivan Plumbing
For over 60 years, Sullivan Plumbing has provided professional plumbing services to Bellingham and surrounding communities in Whatcom County. We began serving the area in 1966 and have continued to grow through the recommendations and continued support of our customers. Our residential plumbing work covers essential home services, including water heater installation and service, bathroom plumbing, drain repair, hydrojetting, water filter installation, and French drain solutions. We are also available for problems involving clogged, slow, or leaking drains and garbage disposals. When plumbing trouble cannot wait, our emergency service remains accessible around the clock, with live phone support available day or night, including weekends and holidays.

We employ licensed plumbers who are trained in the newest technologies and equipped with mobile, fully stocked service vehicles. These vehicles carry tools and equipment for diagnosis, repairs, and installations, allowing us to handle most work without unnecessary trips to a supply house. Our approach emphasizes timely service, careful workmanship, and complete cleanup once the plumbing work is finished. We stand behind technician-performed work with a 12-month warranty and repair the same part at no cost if it fails during that time. Our Protection Plan includes no service-call charge, a 10% repair discount up to $100, 24 months of warranty coverage, priority service, an annual water heater flush, and a whole-house plumbing inspection.

Services
Water Heater Services We specialize in replacing water heaters and installing both tank and tankless systems according to applicable codes. Our technicians diagnose your hot water needs, present suitable options, and walk you through the information needed to make an informed decision. With proper maintenance, tankless units can provide two to three times the life expectancy of tank systems.
Sewage Pump Service We provide sewage pump maintenance programs for all sizes and styles of pumps to support longevity, reliability, and efficiency. Our maintenance technician performs an amperage test, evaluates the float tree, and inspects basin sealing. We also test the high-level alarm, check cutter blades for damage or debris, and remove soap or grease buildup.
Emergency Plumbing Service Our team provides 24/7 emergency plumbing support because urgent problems cannot always wait until regular business hours. Calls are answered by a live person who can promptly send a plumber. We address a wide range of emergencies, and our fully stocked trucks help us repair problems without unnecessary delays caused by supply runs.
Sewer Line Services When sewer line problems arise, we provide professional assessment and repair options tailored to the condition of the piping. Warning signs may include repeated backups, slow drainage throughout the home, persistent sewage odors, gurgling sounds, or unexplained wet areas outdoors. Our team then applies trenchless or traditional replacement techniques as the circumstances require.
Main Water Lines Our main water line services are designed to keep fresh water flowing reliably from the municipal supply to your home. We handle new installations, repairs, and replacements for damaged or aging lines. By evaluating the pipe material, damage, soil conditions, and other relevant factors, we determine a suitable solution using high-quality materials built for durability.
House Repiping Service When outdated plumbing causes reduced pressure, rusty water, unusual pipe noises, or frequent leaks, we offer whole house repiping as a lasting solution. Our experienced plumbers inspect the current system and discuss specific needs before developing a tailored approach. We then replace deteriorated piping, verify every connection, check for leaks, and leave the area clean.
Water Leak Detection We help protect your property by locating and repairing hidden plumbing leaks before they become more serious problems. Our approach combines accurate detection methods with professional repair techniques, covering issues from minor pipe patching to extensive re-piping. Before beginning work, we explain the necessary repairs and estimate, then complete testing and cleanup.
Gas Line Service We deliver gas line services covering the full process from initial evaluation through final testing. After reviewing your system and requirements, we prepare a transparent estimate and address necessary permitting. Our certified technicians perform installations, repairs, or upgrades according to applicable codes, then rigorously test the lines for leaks and proper function before completing the service.

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!

I just took advantage of Sullivan's "protection plan", which includes an annual water heater tank flush and while-home plumbing inspection along with other perks like waived call-out fees and priority service when they're busy -it's affordable peace of mind. This is the second time I've done business with Sullivan, and the two plumbers and one office staff that I've met have all been great. Nick's inspection was thorough and diligent, and identified a major problem - excessive water pressure - that would otherwise have gone unnoticed until it caused an unpredictable failure. I'm happy with Sullivan and plan to stick with them.

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.

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.

Can't heap enough praise on Sullivan! Very highly recommended. Great service, wonderful people. From our first call to the office, to the same day service to remedy our issue, they were terrific. Amy was very nice, and got us scheduled quickly. Kody showed up after what would have been his last call for the day, and we were only expecting a diagnosis and estimate. But even though it was getting late, Kody diagnosed the problem and solved our issue! He was very kind and cheerful. No need to go anywhere else.

Sullivan replaced a few leaky hose bibbs and some water supply lines for my faucets. The same person that provided the estimate also did the work, which was awesome. They finished the work in a timely manner and worksite was cleaned up really well. I will recommend them to my friends and neighbors.

Fantastic service from Kody Prosser at Sullivan Plumbing! Our 50 year old, main waterline was leaking and was located under our driveway. Kody brainstormed the perfect solution and in a little over a day we had a brand new line installed and the job site is clean and tidy! Very professional. Very fair pricing and we got a senior discount. If we could give 10 stars we would! A+++ for Kody and Sullivan Plumbing. The customer care and service are outstanding. Dont hesitate to call this company.

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.

I had water coming out of the front of my new house yesterday. My usual plumber was fully booked and recommended Sullivan.

I called and they were out within an hour. They found my issue (which was luckily minor) and got it fixed quickly.

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.
