Recommended Customer Reviews
I do want to start off by saying I cannot comment on the quality of their work but only on the communication and estimate process. I called in after reading pretty stellar reviews on Yelp. We had a few plumbing issues to address so I called in and Megan answered, she was very nice on the phone and asked me to forward some pictures of the faucets. I sent those in and called a few hours later. She said she was still checking into it. I called in the next day around noon and they were still trying to get prices together for an estimate. I finally got a call back around 3pm the next day to say they were going to refer us to someone else. By that time I already had found another plumber and already had the issues repaired.
So all in all they were always very courteous on the phone to me but very slow in communicating an estimate, which in the end they were not even able to provide. I cannot speak bad about the quality of work they provide since I did not end up using the company for the repairs. I would give 3 stars but according to the yelp rating that is ""a-ok"" and this experience was more like the two star rating of ""Meh. I've experienced
Walked up this morning to 21 degrees and clogged kitchen sink. This was Saturday so most of the places weren't willing to help but O'Neill. I called at 8:30am and Shannon was here at 9:30! They took care of the problem, which turned out to be a frozen pipe. They were courteous and just overall professional. Problem is fixed and I'm happy with the result. I was surprised/shocked to receive a call from Shannon earlier same day to see if everything was fine with their repairs. Service wasn't cheap but you get what you paid for. It was well worth it IMHO. Overall I'm pleased and impressed. I'll be using them from here on.
We decided to replace our 19-year old hot water heater. Even though it performed like a champ, who knows when it would give up. So, I got three bids. O'Neill's bid was right in the middle of the pack and they had a great attitude, so I picked them. I am convinced I made the best choice possible.
Things I liked:
1. The owner and guy who lead the job, Shannon, is friendly and has a great attitude. His admin, Megan, is also extremely nice. His helpers were great.
2. They called me 30 minutes before they arrived, and they were EARLY!
3. They finished the job in less than 3 hours, faster than they estimated.
4. Shannon took time to answer all my questions and then some.
5. They kept everything clean and made sure my house looked the same as when they arrived.
6. They back up their labor with a warranty to match that of the water heater.
Things I did not like: I can't even think of one.
Folks, this is truly one of the best contractor experiences I've ever had. If you need plumbing work, I STRONGLY RECOMMEND you consider O'Neill.
I have to echo everything that's been said by the other 5-star reviews here. Shannon goes out of his way to deliver exceptional customer service -- he's always available, very prompt, reasonably priced and does great work.
He went above and beyond to repair issues caused by the condo builder and was extremely proactive in dealing with me (as the renter), the homeowner and the condo association.
I selected O'Neill Plumbing after a search on Yelp and the large number of positive responses. I had a leaky hose to the sink in my bathroom but didn't have the correct tools to fix the issue on my own. Megan set up the appointment over the phone and I was impressed that there was a one hour arrival window instead of a larger one. Shannon called in advance and let me know when I could expect him to arrive. Once on-site, he outlined what the issue was with the hose and how it could be fixed. I was impressed with his communication and clear explanation of what was wrong. He also made to sure to note that I should call back if any other questions came up later regarding the work that was done. Overall, a very positive experience. I will definitely contact O'Neill Plumbing again when I am in need of plumbing services.
I had scheduled an appointment to have O'Neill plumbing come out to fix our toilet after all of the rave reviews on Yelp. My husband took off work for their arrival but they just never showed up. I tried calling several times to see if there had been an emergency requiring a rescheduling but no one picked up the line. It's now been over a week and no one from O'Neill plumbing has even bothered to return my messages. Needless to say, I'm really angry at this unprofessionalism and complete disregard for our time.
Talk about top notch plumbers. Shannon is a really good dude. I needed him to dewinterize a home and then winterize it. I called him at 6am to schedule an emergency same day visit and he fit me in to what was probably an already busy day. Shannon called me at 12pm to tell me that he had some time extra time, so he could fit me in earlier than our scheduled time. He was waiting for me, early, when I got to the house. First, he did the work and explained what he was doing and then gave me an estimate before doing any work. Took about an hour to do the work and then he checked a few other small things in the home for me.
I needed him to come back to winterize the home about 3 hours later which he agreed to do.
I was late to our return meeting, but Shannon took it in stride and still met me as agreed and did the job which took another hour. Yeah, he wasn't fully happy about me being late and having to do a job later than planned, but we worked it out and Shannon did a great job. I fully recommend O'Neill plumbing. Shannon is a good, honest guy who does great work. Highly recommended.
Wow.....I woke up New Years morning to a water heater that smelled like it was on fire, and water spewing out of the bottom into my basement. I called O'Neill after calling another place who couldn't make it out until Monday. Megan took all of my information and immediately transferred me to Shannon so I could talk to him about what the issue might be. He came out to the house telling me he didn't have a tank big enough but he would still come out and see what the issue might be. He got here right on time, and even called 30 mins ahead of time to verify he was on the way.
He took one look at the water heater and noticed that the wires were singed and that, as I thought, the water heater needed to be replaced. (We found out the water heater was from 1986!) He understood that we were desperate for hot water, and called around to find us a water heater that was big enough. He then left to go pick up the bigger water heater, brought it back and installed it with no issues, until it was time to turn back on the breaker. We then discovered that the breaker had shorted and it needed to be replaced in order for the water heater to work. He called Home Depot and figured out which breaker we needed, and left again to run to home depot before they closed. On his way back from Home Depot he called again to make sure we knew he was on his way back.
When he came back, he replaced the breaker and Voila we have hot water!!!
Throughout the day he was always professional, timely, explained everything to my fiance and I, and was very friendly. I will recommend O'Neill Plumbing to everyone I know, and will be a customer for life.
Alison G.Okay, Shannon is awesome. Called me to see if he could arrive a little early, which I love, and then was super nice and funny while he was here. Offered to show me exactly how he was fixing my garbage disposal, walked me through the whole thing, and kept me highly entertained the whole time. Plus he gave me a tip for making better shepherd's pie. I want to just hang out and have a beer with this guy.
Huge fan, and I'll be a permanent customer.
I waited a few months to write this review, but after being ignored and hung up on... I decided it was time. I found ONeill through Yelp and I want others to know my experience.
O'Neill plumbing came to my condo to replace a hot water heater. Shannon left his ""best plumber"" to finish the job. Well his best plumber installed it incorrectly, resulting in water damage to my downstairs neighbor's condo AND a gas leak into our condo. Shannon came later that evening and corrected the installation.
During this time, he agreed to pay for the damage to my neighbor's place (under $500)... he even provided his insurance information. I sent him the invoices and a letter requesting payment. This was ignored. I called Megan at the office multiple times and she always had an excuse (new baby, trucks broken into, etc). I finally called Shannon directly and he said that he didn't believe that he should pay and then hung up on me.
I was all prepared to write a positive review, because mistakes happen, Shannon corrected the problem that day and was agreed to reimburse us.... however because we have not received payment and I was mistreated by Shannon, I feel that this review is necessary.
