ONeill Plumbing offers comprehensive general plumbing services, including faucet repairs, toilet installations, water heater replacements, and drain cleaning. Our team addresses both minor leaks and major emergencies with precision and care. With over a century of experience, we ensure reliable solutions that meet modern standards while preserving property integrity.
Underground Utilities
Our underground utility services include sewer cleaning, hydro jetting, and trenchless pipe repairs. Using advanced equipment like electronic pipe locators and video inspections, we resolve issues with minimal disruption. This approach reduces excavation needs, saving time and costs while restoring functionality to sewer and water lines efficiently.

We handle clay, concrete, and PVC pipe issues, offering durable solutions that extend system lifespan. Our methods prioritize environmental sustainability and cost-effectiveness, ensuring minimal property disturbance during repairs or replacements.

We provide water heater repair and replacement services for residential and commercial clients.

I used O'Neil this summer to re-pipe, install new kitchen and bath fixtures, new drains under kitchen and bathroom sinks, new water heater, new outside faucets in home. Re-pipe was to be done in crawl space--which is very difficult since the work is performed in awkward positions. I had stressed to the service manager as the re-pipe was being done should the plumber come across anything else that should be repaired/replaced to notify myself for authorization to repair. After the entire job was completed, O'Neil had to come back twice once to repair leaking kitchen drain and repair

Professional, courteous, and efficient. Our basement bathroom/laundry room drains started back flowing sewage on a Sunday, after Christmas, in a snowstorm. They were honest that the earliest appointment was Tuesday (but no other plumbers could come earlier either), were punctual even though they were concerned about ice on the roads, treated my home with a respect that past plumbers have not (covered their shoes, did it scratch tiles), and got the problem fixed in an hour. There's nothing like living with sewage for two days to really appreciate a good plumber!

Last night during a midnight trip to the little boy's room I realized that my normally dry bathroom had turned into a walk-in tub. There was water all over the entire floor and it was almost at the point of seeping out of the bathroom. After sacrificing a roll of paper towels to clean it up I found out the culprit was a broken shut off valve under sink. I got online and chatted with O'Neill Plumbing's chatbot. Within ten minutes a real person wrote me back saying they would call in the morning. And they did! They called at 7:30 and there were two plumbers at my door by 8. The plumbers

From initial diagnosis, to talking through repairs, to actually fixing the issue - Jeff R. went above and beyond my expectations for a gas fireplace shutoff valve repair. ONeill's bid came in less than two other highly regarded plumbers, and they even found a way to replace the valve without cutting a hole in my drywall (other plumbers said no other way to replace w/o cutting). Will definitely call Jeff & O'Neill for any additional gas plumbing, and likely any traditional water line plumbing as well.

I also had an emergency request with a clogged sink in a condominium and wanted to prevent any further damage. They were prompt and so professional. John K explained everything thoroughly. He was quick and efficient. I had just had foot surgery and I was on a knee scooter, he even offered to go to 711 for me if I needed anything. Just very kind. He also mentioned that he really liked working for his boss and a great dispatch gal as well. I believe if you like the people you work for it shows. A huge thank you to John K and this company . I would highly recommend !

So impressed with this company! We needed a hose bib fixed. They came the next day and we're so incredibly efficient and kind, and made it happen for us surprisingly quick and for far less then we expected. I will be going to O'Neill's for all our plumbing needs from this point on.
