I placed a call to O'Connor Plumbing for a job in mid-September for a residential job.
They stopped doing residential business three weeks ago. (They did not alert me to that)
They called me up today (October 11th) to confirm a time and date for them to come out.
I confirmed the date still worked.
They called me back to say, they haven't done residential work for three weeks and would not be coming out.
They at no point apologized for not reaching out to me sooner, for cancelling my appointment and stated they did the best job they could do for me (whatever that means).
So, if anyone does business with them, please heed my warning that they will not be taking any accountability for any mistakes on their end.

This was just brought to light by another plumber. They left our yard a mess. It is not graded like it should be. The dirt is just a mound and you sink in when you stand on it. They didn't level it or compact it like it should be.. Another plumber told us that the water can collect right against our house. They rushed to get the project done at the end. This new plumber said that they did that kind of work for 6 years and they never would have left the yard like that.

When I called O'connor back to come fix it, the owner, Jason, kept saying he would stop by. He even agreed through text message based on the pictures I sent him that it was slanted towards the house. Then I get an email from Jason, the owner, saying that as per the contract they don't do anything with settlement after the work is completed. They never graded it as per the contract. They were dishonest. Also, supposedly they hydrojetted our pipe. The new plumber said it did not look like it! I would look elsewhere for a plumber.

Now our basement has flooded twice. It floods everytime it rains, our floors are ruined and we have to get the window well repaired. We are going to have to put out a lot of money to fix it.

New toilet installation was seamless and the craftsmanship was top notch.

Start to finish was about an hour. We purchased the toilet ourselves based on their recommendation and are glad that we did.

Another wonderful experience with O'Connor Plumbing. Problem was diagnosed and repaired quickly and efficiently. They made helpful suggestions for parts but never pressured me to make a specific decision.

Thank you all for another great experience!

I called O'Conner plumbing since I had a leak in the toilet I was very familiar with as I had fixed it myself before in the downstairs bathroom. However, this time I was recovering from surgery and was on bed rest. I had paid less than $5 at Home Depot for the replacement parts and told my wife they will probably charge us up to $100.

Day of the repair a ""Trevor"" came by and he said the issue was with the water tank screw and it matched the exact same scenario I had encountered before and fixed. On the brightside, I would say Trevor was very courteous and respectful and efficient in his repair fixed in it in half the time it took me and the repair was done to my liking. However, prior to the fix, as I was prepared to be overcharged, I was overcharged more than I had predicted. I was expecting up to $100 but Trever from O'Conner Plumbing charged me $135 for a job that would cost less than $5 if I had done it myself.

So, if you want something done quick, efficiently, with a friendly customer service who will also charge you up the A$$ use O'Connor Plumbing. They get it done right and expensively.

Horrible. Gave an estimate of $1,500 to replace a drop-in kitchen sink; we already had the sink and faucet. They came up with all sorts of reasons to replace and upgrade every possible thing related to the plumbing we've never had an issue with. Never got the estimate to replace the septic pump after two visits (service charges of course) because they wanted to charge a minimum of $450 to run a camera through the line first, etc. or they couldn't warranty the pump.

We've used O'Connor plumbing three times now. They replaced all the drip lines to our toilets, installed three toilets, and repaired the drip line to our refrigerator. They've done a very good job each time! Will definitely be calling O'Connor again for any plumbing work in the future.

I LOVE using O'Connor Plumbing! Whenever I call them they are also polite and informative on my situation. This is the second time I've had them do work in my home and they never disappoint. My technician this time Tyler, I was very informative and gave me all my options to help me make the best choice for my home. If you are looking for an excellent plumber call and ask for Tyler!

O'Connor plumbing has extremely poor schedulers. I called and asked to set up service for my home. The appointment was scheduled. At the time the appointment was supposed to occur I received a call saying they would not be able to come and the appointment would need to be re-scheduled. I adjusted my work schedule a second time to accommodate the change. They then asked me if I new where the water shut off to my building was. I said I didn't and could look into it and I could get back to them. That was all they said. The morning of the appointment I called to confirm and let them know that the shut off was not in my condo unit. They told me they would have to again cancel the appointment. I would need to have my management company make the appointment and all charges would go to the management company which could be forwarded to me. They did not tell me any of this in either of the two conversations before and the women on the phone was not empathic and often spoke over me not allowing me to speak. I don't know how they are once you get them to provide service; however, actually getting them to provide service was not a good indicator.

Multiple very poor interactions with O'Connor. Cody replaced our hot water heater and was professional and punctual. Following that, we called them back to fix a pipe leaking under a bathroom sink and two shower faucets. The pipe leak was seemingly quickly fixed, as was shower #1. We were told they would have to order parts for shower #2, which would take a couple of weeks. A month after the initial ""fixes,"" there was a lot of water in the sink cabinet due to continued leaking and the wood had cracked and warped, and shower #1 was leaking again. We had not heard back about the parts on shower #2. A different plumber came back to fix the sink issue, was there 10 minutes and ""fixed"" it again. Within hours it was leaking. A third plumber diagnosed incorrect work previously done, repaired it and took photos for an insurance claim. He also took photos of the shower faucets so he could order the correct parts (weeks after we raised the issue). I followed up twice with the office on the insurance claim and never heard back. Four weeks after the shower parts were supposed to be ordered, the plumber called to say that he had finally connected with the distributor and the parts would be in after two weeks, and they would then call to schedule the repair. That was six weeks ago, and we never heard from them again. Absolutely abominable customer service and workmanship - I am surprised they have any repeat customers.
