Reviews

What customers say

Customers praise careful, professional work and tidy finishes. After a main sewer-line replacement, one customer said the garden looked better than before; another described an appointment moved later the same day after a plumber called in sick, then praised the communication and said the crew arrived early for the revised time.

Van Nelson

We had our main sewer line replaced. The O’Neill team was the most professional and conscientious group I have ever had the pleasure of hiring, and also a great group of people. They were like surgeons operating in my small yard. When they finished, the garden looked better than before they started! I highly recommend Oneill Plumbing.

Ikuto

The office-home unit I currently use had not been updated for many years and required major repairs. This included work on two toilets, the sink, shower, and hot water system—and on top of that, the water heater was located in a very inefficient spot, which made the job even more challenging. Despite all of this, everything was handled quickly, carefully, and professionally. Ricky Gillespie and Hunter were not only highly skilled but also extremely friendly and pleasant to work with. Both of them were wonderful, and I will definitely request Ricky and Hunter again for any future repairs. Thank you very much for your excellent service.

Kenneth Poston

My first time using O'Neill Plumbing service and was very much impressed with the quality of customer service; to wit: had an early appointment confirmed, however, plumber called in sick and dispatch advised would be later. The new time (same day) was amenable, and they arrived 15 minutes early. Ricky and Hunter were very professional, as they proceeded to clear my drains. The cost was reasonable and communication was great. At this juncture, I would not hesitate to recommend them to others for plumbing needs.

Linda Grimes

We recently discovered we had a leak in our water service line into the house as evidenced by a water bill 200% higher than normal. Having used O'Neill Plumbing previously with good results, I gave them a call. They came out quickly, gave us a price and started on the repair quickly. The crew (Mike M, Mike and Jesus) were great to work with. They knew what they were doing, worked efficiently, protected the landscaping and cleaned up after the job was completed. We would not hesitate in recommending O'Neill Plumbing.

Gus Catalano

I've hired o'neill for a bunch of smaller projects over the years with great success. Most recently I hired them for a big project of a gas line upgrade, hooking up a generator, hooking up a tankless water heater and a whole house water shut off. I had the pleasure of working with Tyler, Ricky, Hunter, Colin and Bill throughout the project. It went really smoothly, they left the place clean, the pipes were run well organized and neatly across the space and they took the time to address the minor concerns I had. I love working with them and I'd hire them again anytime. It's clear why they've been around for so long they're amazing at what they do.
