Services
We replace and install water heaters using both tank and tankless systems, with work performed according to code requirements. Our technicians help identify the most suitable approach for your hot water needs and explain the differences clearly. Tankless equipment can offer 2030% efficiency gains and greater longevity, while tank systems can provide simpler, less costly installation. 
We maintain sewage pumps of all sizes and styles with procedures focused on reliability, efficiency, and service longevity. Our technician begins by testing amperage and evaluating the float tree for proper wastewater cycling. Basin sealing is inspected, the high-level alarm is tested, and cutter blades are examined for damage or debris before buildup is removed. 
We are available day and night to assist with plumbing emergencies whenever they arise. Our service begins with a live person answering your call and arranging fast dispatch. Whether the issue involves a drain, toilet, water heater, pipe, gas leak, faucet, or sink, our trained plumbers are prepared to respond and restore service. 
Sewer line failures can result from tree root intrusion, shifting ground, aging cast iron or clay piping, and improper disposal of materials. We provide dependable repair and replacement services to address these conditions. By evaluating the plumbing system carefully, our team can determine whether a minimally invasive trenchless solution or traditional replacement is appropriate. 
We provide comprehensive main water line installation and repair services to help maintain a consistent, healthy water supply throughout your home. Our team addresses leaks, blockages, corrosion, breaks, and other main line concerns with reliable solutions. Whether installation, repair, or replacement is needed, we assess the situation and recommend an appropriate course of action. 
Our whole house repiping service addresses plumbing systems affected by corrosion, mineral buildup, brittle pipes, and repeated leaks. We begin by evaluating the condition of the existing piping and identifying problem areas. After selecting appropriate materials, we remove failing pipes, install secure new connections, test for leaks, and thoroughly clean the work area. 
Our comprehensive service combines precise leak detection with dependable plumbing repair. We investigate water intrusion using advanced methods capable of revealing leaks through sound, temperature changes, tracer gas, or interior pipe views. Whether the problem involves a slab, water main, or another plumbing component, our skilled team repairs it and verifies proper system performance. 
We handle gas line needs with careful attention to safety, compliance, and performance. From connecting new stoves, dryers, fireplaces, and outdoor grills to upgrading older lines, our technicians provide precise installation and repair work. We also use advanced leak detection, complete required permitting, pressure test new or repaired lines, and confirm safe function.

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!

My water heater was leaking. I called for emergency service. He offered to walk me through it or come over. I opted for coming over. He arrived promptly, shut off valves hooked up pump and hose and promptly drained tank. Also helped clean screen on my washer removing silt and connected everything back. He explained everything,was professional and courteous and cleaned up any messes. I would recommend Sullivan plumbing to everyone.

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!

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.

I could not be present for the work but trusted Nick who I had met before. He kept me apprised and corrected the problem we had. What is remarkable as well is that I had flagged him down a few months ago when I saw him leaving my neighbors house. I needed a plumber to assess a poorly draining sink. He assessed it and gave a couple of suggestions we could try before investing in an expensive repair. Honest, considerate, and capable.

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.

We have been using Sullivan Plumbing for 20 years on 2 separate homes. They have installed new shower and bath plumbing, toilets, water heaters, also kitchen sink plumbing along with a new garbage disposal (May 2025). They also set up the well pump, outdoor faucets etc. So we have used them extensively.
We have always found them to be professional, highly skilled and generally -- on the ball. In addition, we also found them to be honest in what could be repaired vs replaced. They are a smaller company, but we see that as a plus.

Kody and Johhny came out and installed our water heater and replaced some of the surrounding plumbing. They did a great job, listened to my requests and cleaned up the workspace and old items before they left.
I appreciate Sullivan Plumbing for their quick service, fair pricing and keeping it local!

Nick was a hero tonight. My wife dropped her wedding ring down the P-trap for the hot water tank in our apartment and we had no access to the actual pipes. Once we called he was here within 45 minutes and very good at communicating what the best options were to retrieve it. It took him 5 minutes to find it with the camera and we had it out of the pipe within 20 minutes. Amazing work and worth every penny. Thank you so much Nick! Would highly recommend anyone who is in a pinch or needs assistance with plumbing to call Sullivan Plumbing!
