They were able to come in and fix my plumbing issue quickly and reasonably

Edmond Shenassa

It was a pleasure to work with Trevor Lamm. He is knowledgeable and super helpful. We would definitely call on him in the future.

Vicki Naas

Austin was extremely knowledgeable and professional. He explained the problems and provided options and solutions while keeping the cost of the repairs in mind and permitting me to choose. The work product was excellent. He is a very trustworthy plumber. I would recommend him to friends and neighbors.

Margaret Kelley

Calvin arrived at the agreed upon time, explained what would be involved in order to unclog a basement toilet obstruction and presented an estimate. He was friendly, patient and efficient as he completed the work. We greatly appreciated his professionalism. The problem is fixed and the clean up was meticulous. I highly recommend O’Connor plumbing and Calvin.

Carol Williamson

Cole was very thorough in checking why I had a brown spot on my living room ceiling, upon removing the toilet upstairs, he was able to suggest it could be a very slow water leak from the previous wax ring. He fixed the problem, cleaned up and explained what he was doing and why. I greatly appreciated his willingness allowing me to ask questions as I need to know what is going on in my home. Thanks Cole.

Shanique Wright

I am so grateful for O’Connor plumbing. Our well pump broke and we were without running water for a month (with three small children it was a very long month!!). We went through at least four plumbing agencies, but the other ones were afraid to tackle the task of restoring water to our home (not going to lie, it was a pretty big task). However, Stephen from O’Connor in Frederick showed up and kept showing up until our water was restored and we are forever grateful!!! Thank you so much!!

Lauren Lang

Calvin collins and Clayton marker replaced our water treatment system. Very friendly, timely, and professional. Absolutely would recommend their services!
