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.

HUGE thanks to O'Connor and especially Ethan and Clayton, who replaced our toilet, the water heater, and redid the shower all while fielding the questions of my two kids, worked around the curiosity of two cats AND the dog! They were fast and efficient, they were friendly, and now a couple weeks later everything continues to work perfectly!

If you want responsive, timely, professional plumbers, this is the company for you! Ethan and Clayton were professional, timely, and did a super clean install! They were able to solve an issue that I've been dealing with for over a year and had other companies unable to fix. I will 100% be using them for any future issues I have as well as recommending them to anyone I know who is having trouble or wants to upgrade. Best plumbers around!

We had Tyler and Calvin at our home recently to install a water heater. What I like about working with them is that they are not trying to upsell. I appreciated Tyler's honesty and thoroughness in explaining everything wrong with our old water heater. Grateful for him making a return trip to our home to make sure everything was working properly. Look forward to working with Tyler again in the future if a need arises. Thank you!

Scheduled a service to have my cracked sewer drains checked, took a day off and waited all day. Was initially told that someone will show up between 8am to 12pm and was assured that we would be the first call. 11:50 comes around, receive a call saying that the guys might be busy and that they will come between 12pm to 4pm and wait patiently. Comes 3:50pm and I call them and the lady states the guys are still busy and may need to reschedule. Can't handle the work load, please do not waste peoples time, it's just as valuable as yours! Will not recommend this place.
