I called at 730 this morning about my water heater leaking and had a new one in by 1130 ..thank you so much ! The guys was great , it was a really tight squeeze to get it to fit but they got it done ! My grandpa and my mom had used O'Brien for decades and never disappointed!
Alyssa Burnett
O'Brien is the best plumber around and you can't change my mind. They have great communication when it comes to timing on services. They do the job WELL and timely, and are upfront on costs, labor, parts, etc. Always recommend them to anyone I can. Something I don't mess around with is cutting corners on plumbing and you can be sure that they don't mess around either.
Jonathan McClallen
Would give more than 5 stars if I could! Excellent company - prompt service and reasonable pricing. Nick B. was amazing and professional - the completed work looks clean and uniform. Ill be recommending him to friends and family! Thank you

Hired them to fix a small leak today. They didn't try to upsell or make things weird. They arrived fast, and were very friendly. I will absolutely go with them in the future.
Don Zapf
O'brien's is awesome. Called early in the morning for a water heater leak, and found our later in the day that the garbage disposal failed too. They came later in the day and worked overtime to get both fixed. Great Company, Great People, Great Service. Nick was our plumber, did a great job on this and other problems we had. Thanks
