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.

I waited 2 1/2 weeks for this company to get me scheduled for an estimate. Today when I called to confirm they are coming between 12 and 2, they didn't see my name. Then he looked up my address and said the estimator was out of the office all week. They never bothered to call me to change the date. It took me calling them! My brother drove 150 miles round trip to meet with the estimator who is a no show. This company cannot be relied upon to keep a scheduled commitment. There is no way I could trust them to keep to a bathroom remodel time commitment that relies on cooperation with another vendor who will be doing tile work.

These guys are fantastic. KJ showed up right on time, went right to work and finished the job in record time. He tested everything to make sure it was in good working order before he left. I ended up paying a lot less than I had anticipated. I have used O'Neill before and never had a bad experience. They're my favorite company to recommend. I give them my highest recommendation. Thank you O'Neill and thank you KJ.

O'Neill Plumbing is our go to company. They recently helped us with a bathroom remodel and it turned out amazing. They are prompt, professional and experts at their job. If you ever need a plumber they are the ones to call. Trusted company.

After having another plumbing company attempt to resolve my clogged kitchen sink drain, I reached out to O'Neill. I was able to quickly schedule an appointment and John Keigley came to my home to diagnose and fix the issue I was having. John was able to fix my drain in under 30 minutes while the other plumbing company took over 2 hours and did not resolve my problem. John took the time to explain what the problem was, offer clear and friendly advice about the issue, and charged a very fair fee. I cannot recommend O'Neill Plumbing enough, and John is an excellent plumber and kind man. 5 stars!

Todd and Jordan were able to get here just over an hour after I called on Saturday afternoon with an emergency request - I can't imagine a better response time, and none of the other 4 companies I called could even come close.
They were thorough, explained everything they did like I deserved the info as the homeowner but not as though I were dumb or uninformed - other middle aged women who've dealt with less skilled communicators understand what I'm talking about!
Todd and Jordan were responsive to my requests, offering services with clear info on what things cost and how long they'd take.
I absolutely recommend O'Neill.

When I called, I was told about the company's time and materials policy. I just wanted to feng shui an ugly nonfunctioning little water heater by getting rid of it and making a cubby in the unused space for my laundry basket. An electrician had assured me that what I needed was a plumber since the water heater was not connected. I assumed the job would take half an hour and that would be an okay price for the job.

Two men came, took a few photos and and told me they couldn't do the job because it required an electrician to move wires. Their 15 minutes was charged at $185. What I hadn't realized was that all the wires hanging down were live and the electrical box would have to be moved permanently to do what I wanted. Not worth it.

I am 72. I recall when venders would give estimates free in order to try to win business. I try to do most things myself because when men come to do it, I get ripped off, but usually they do something. I just got through
shingling my shed roof for less that what it took for these two ""plumbers"" to do nothing, take my money, and not feel bad about it.

The time-and-materials company is now off my list.

I have used O'Neill plumbing on several occasions both at my primary home and my rental, and have always had amazing service. Most recently I had an issue with my sink at home and I had to have it looked at twice. The second time they sent someone who spent an hour there to make sure that it was all working properly, and the company did not even charge me for the follow up! Their service is impeccable, all of the people I have dealt with are courteous, knowledgeable and simply wonderful, which is rare these days. I highly highly recommend this company.

Jeff showed up early, looked at my 40-50 year old shower valve and made it work. Others had tried and failed. Gave me an honest appraisal and good advice. Outstanding.
