Services
We provide water heater replacement for both tank and tankless systems, including code-compliant installation. Our technicians have manufacturer-trained credentials and can help determine the right water heating solution for your needs. We explain the differences between available systems, review important considerations, and ensure you are satisfied with the completed project before we leave. 
We perform comprehensive maintenance on sewage pumps regardless of their size or style, with the goal of preserving longevity, reliability, and efficiency. Our technician assesses amperage, checks the float tree, and examines basin sealing. High-level alarm testing is included, as are physical cutter blade checks for damage or debris and removal of soap or grease buildup. 
Our emergency plumbers are trained to respond when plumbing problems demand immediate attention. Service remains available around the clock, including nights, weekends, and holidays, with a live person ready to receive your call. We handle common emergencies such as clogged drains, toilet repairs, water heater issues, pipe repairs, gas leaks, and faucet or sink problems. 
Our sewer line replacement and repair services combine experienced workmanship with advanced technology. We address damage associated with roots, ground movement, aging pipe materials, and clogs caused by improper disposal. When feasible, trenchless pipe lining or pipe bursting can reduce excavation, whereas traditional replacement allows us to remove and replace severely compromised sections directly. 
Main water line problems can interfere with the water supply and may result in property damage when left unresolved. We provide professional installation and repair services for these critical plumbing lines, as well as replacement when necessary. Our team can diagnose leaks, blockages, corrosion, and breaks while selecting between traditional excavation and trenchless methods according to the circumstances. 
Our comprehensive repiping service replaces failing plumbing throughout the home rather than addressing recurring problems individually. We evaluate pipe condition, recognize signs such as rust, low pressure, leaks, and unusual noises, and develop a suitable replacement plan. Whether PEX or copper is selected, our experienced plumbers install the new system, verify its performance, and complete the necessary cleanup. 
Our team provides dependable leak detection and repair services using specialized knowledge and advanced equipment. Acoustic devices, thermal imaging cameras, tracer gas detection, and video inspections allow us to investigate challenging plumbing issues precisely. We then deliver effective repairs, test the completed work, and provide preventative advice to help maintain your plumbing system. 
Our gas line installation and repair service is designed to keep residential systems secure and functioning properly. We install and modify lines for household gas appliances, investigate suspected leaks, and repair compromised connections. Each project includes careful planning, compliance with local requirements, appropriate testing, and professional cleanup to support a safe and dependable result.

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 chose Sullivan because of our years with you. I'd disassembled our washer/dryer and a laundry sink for a new floor installation and felt professionals should do the reinstall of everything so it was done properly and that's what happened. Nick and Johnny came this afternoon and got everything back and running smoothly. I was very impressed at how thorough they were in evaluating what needed to be done and doing it. Thanks to them and your company.

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!

Sullivan Plumbing has saved us so many times. Last week they installed a sump pump in our crawl space and routed it to the existing storm water drain pipe at our property line. They worked very hard digging a trench and a hole for the sump pump. Very professional, courteous and made sure they didnt leave without asking if we had any questions. They even coordinated with an electrical contractor who was unable to dig around the hard, impacted soil outside to place grounding rods. Such great service and attention to detail Kody noticed a leaky pipe in the crawl space and came back today to fix it. My water karma is restored with Sullivan Plumbing!

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.

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.

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.

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.

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.

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 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!

We recently (last week) had really a water line bust. We got a bid from Gary's Plumbing 1st, because they are closer... but the bid was a shocker- rooskie. My daughter makes a bit more delivering babies! We had Sullivan come out and take a look... .. The Tech/Plumber was Nick. Okay, my husband was in Construction, he still is the hardest worker that I know. Even at retirement, most people's work ethic DOES NOT impress him. Nick's did. And when we got the final bill, it was literally THOUSANDS under what we expected. Nick and his Co-worker had the entire job done HOURS under the anticipated time frame! They even personally dropped off a few tools that we left at the job site.

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!!
