This is a stellar plumbing service! The owner Shannon is extremely knowledgeable and takes pride in his work, something that is SO hard to find now-a-days. My hot water heater died abruptly in December and since it also pumps my heat, I needed to get it fixed ASAP. O'Neill plumbing was able to acquire the special type of water heater my condo requires and install it in the same day. The crew went above and beyond to make sure they left my place neat and the owner Shannon called me a few times afterward to make sure everything was working right. Plus he gave me a great price that was the lowest of the four quotes I had gotten and included a six year warranty. A month later my heat pump stopped working and O'Neill Plumbing came out within 4hrs to help. Shannon and his crew diagnosed the problem within 2min and had it fixed in 15min free of charge. I would recommend this service to everyone!

****Absolutely a must call if you have a plumbing emergency or issue!!!!!****

I had the expansion tank above my hot water heater begin leaking, on a Sunday no less. After calling my home warranty company and waiting for them to contact their preferred company and calling them back over and over to explain the issue (about 5 hours) I decided to turn to YELP. O'Neill's popped up and I couldn't have been happier with their emergency services.

Shannon immediately answered their emergency line and was quick to tell me he was happy to help and would be there in less than an hour.

As to the service, Shannon (the owner) personally walked me through everything he was doing and the different options available to me. I appreciated that he was completely honest and didn't force me into a decision so that he could make money. He had another plumber with him to assist, Zack, who was completely professional and allowed the job to be done within a reasonable timeframe.

Highly recommend this professional plumbing company!!!!

These guys rock.

I had a small tub plumbing issue come up that came as the result of a bad prior owner and/or condo manufacturer. It wasn't a huge problem, but definitely needed professional work, and it required thinking outside the box and a bit of welding. Most plumbers in the area wouldn't spend more than a second or two on the phone with me before virtually running off and/or demanding huge sums of cash - but that didn't happen with O'Neill.

I spoke almost immediately with Shannon, who spent no less than 30 minutes on the phone with me running through potential fixes for the problem. He then quoted an extremely reasonable price, which made me pull the trigger immediately. When he arrived (on time and with plenty of prior notice), he and his crew had my tub fixed in 10 minutes - and he even fixed some other nearby stuff gratis. It was remarkably clean, painless, and professional work.

The nice thing about this work was how ridiculously talented Shannon was. He was able to spot issues with lightning speed and fix them in about the same amount of time. I didn't have to sit around explaining the situation and waiting for him to process it - and that's pretty rare, especially in plumbing.

Needless to say, I can't recommend this place highly enough.

I never experienced such a rude and unprofessional company. My significant other called and scheduled an estimate apt with the O'Neill's. At first upon arrival Shannon was very polite he complimented our house and explained the quote and the work to be performed. He told us that he had to cut into the wall to find the problem and that it would cost $150. We agreed to the work and I left leaving my significant other at the house. I am the owner of the house so I told my significant other to call me and update me on what needed to be done and the additional cost once they found the leak. Shannon found the leak to be a pipe and informed us that we had wood that was rotting and possibly mold behind the wall, in addition he would need to cut the pipe and fit the pipe, and that this would cost an additional $275. My significant other was trying to explain this to me through the phone but I was not clear and wanted to speak directly to Shannon. I addressed him with respect and asked was it true that nothing else would be performed besides the cutting and fitting. He then explained that he cut us a deal on cutting through the wall and that yes he only does plumbing. I said wow I didn't know things like this cost so much and said thank you and asked to speak with my significant other so we could make a decision. As soon as my significant other got on the phone with me I heard Shannon in the background yelling and saying ""you people want work for nothing and that he didn't want to perform the work and that he was packing up and leaving"". He was very irate and cussing and unprofessional all because we asked some questions about pricing. This was all while my significant other and I were just trying to decide whether or not to move forward or to attain another quote.
So we told him to get his ""shit and get out"" you don't come to someone's house and start disrespecting them. Then the story gets even worse, I called the main office and explained the story to the lady that picked up the phone, at first she listened and apologized for my experience. I informed her that I would be writing this review on here and Angie's list, plus the better business Bureau. I then said that they should talk to Shannon about his professionalism. She then got upset and started yelling and told me that I was unprofessional because I left; I tried to explain to her that my significant other was there but yes he still had to get my approval. She just kept yelling so I hung up on her. I will never recommend this company and anyone who uses them beware that if they come out for a quote be prepared to use them for the work or they get really upset and disrespectful.
This was one of the worst experiences I have ever received and I never even want this business mentioned to me in conversation.

Had a stubbornly stuck drain. Contacted two other plumbing companies that made appointments with me but then they didn't show up or couldn't be on time. Called O'Neils and from the moment he showed up (early) to my home until the moment he and his crew rolled up the protective tarps they thoughtfully placed from the front door to the problem area he and the company were considerate competent and their attitudes were great! Will definitely recommend the crew and the company and if ever I need a plumbing company again they will be the only company working in my home.

We had a rather poor customer experience with Shannon. We talked by phone about installing a hose bib which he indicated over the phone would be about $1,000. When he shows up he says its was much more complicated than he envisioned and that he would need $1,600. I just wanted the job done so agreed. The job was to take the copper piping inside the drywall. However, he encountered an obstacle and instead ran the pipe outside the drywall which of course was less labor. Anyway, when he was done there was a 2X2 hole in my drywall. When I asked him about putting the drywall back in place he tells me that the piece he removed was broken and that he doesn't have any drywall to replace it with. Then he goes on to tell me that he told my wife that he does not repair drywall. I wasn't looking for a repair, such as patch, sand and paint but rather just that he not leave a gaping hole in my ceiling. Anyway he refused and got quite cantankerous and legaleze with me. Basically he refused to replace what he had taken out said he doesn't do drywall and that if I wanted it done he could get a man out the next day for an additional $200 dollars. Realy!!!

Then the conversation moved on to payment and he indicated that in addition to the charge that he was entitled to a 3% add on for use of a credit card for payment. This was never mentioned in his original quote and he tried to tell me that he is allowed the amount pursuant to law. He then tried to tell me that it is clearly posted on his web site which I never visited. Anyway as you can imagine the conversation did not go well. At one point in the conversation he threatened to remove the plumbing he installed. That was when I called my son and asked him to pay him by check and escort him off the property.

Basically, Shannon comes across as a bit of a shyster having only his interests in mind. I would never ever consider using this service again as the guy wants to draw legal lines and argue with his customer until he is blue in the face. Additionally, think about it, he was on site for four hours. The parts were about $150 so for the labor he thinks he is worth @360 and hour. Pretty much a big rip off.

Shannon was exceptional. O'Neill is now our go-to plumbing service because of Shannon's quality customer service, responsiveness, willingness to go above and beyond the task, and knowledgeability of a wide range of issues. We had called a few other plumbers to re-route a pipe so that we could install a new washer/dryer, and no one had returned our call. We called O'Neill's at 1000 and were told by the office staff that it didn't look like they would be able to take on our job. Shannon demonstrated the personal touch he puts into the business and his customers and called us back a few hours later to say he had reviewed the pictures we sent him and could take care of our problem after dinner that same night. He and Carlos came by, quickly assessed our problem, got to work, and were done in about an hour and half. Shannon explained what he had done and gave us some advice on how to integrate the new pipes with our new washer/dryer. We couldn't ask for a better or more trusted plumber.

Shannon and his team were very helpful both before and during the repair. He is very professional and I would recommend O'Neill Plumbing to anyone in the D.C. area.

I contacted O'Neill Plumbing related to a plumbing issue with a leak in my condo after seeing the great reviews on Yelp. I didn't end up needing their services because it turned out to be an issue that the condo took care of. I wanted to highlight a few things however- professional and courteous communication by Megan who handled scheduling and setting up an appointment for the following day. I haven't needed their plumbing services, but if I ever do, I will know whom to call. Thanks Megan!
