It's reassuring to know that your home is in good hands with professional experts. I was referred by a plumbing supply store. When I asked who could help with my problem, James & James Plumbing was the first business that came to mind.

I reached out to Cody, who is very personable, professional and responsive. He answered many of my questions before coming out and fixed my problem to perfection. As part of their service they do a full inspection so he fixed other issues that I wouldn't have spotted and took care of everything in the same visit.

They are timely, communicative and have a genuine willingness to help. I will definitely call on them again.

O'Grady is by far the best plumber we've worked with.

Great customer service. Very knowledgeable Plumbers. Highly recommend.

Fireplace would not light upDavif had a remote control that did the trick
Costly though

I’ve used this company a few times, always a pleasure!

Daniel showed up on time 9 a.m. Thursday, cleared out the tree roots that seem to be the cause of the clogged garage to street drain, and tested it afterward. The entire job was done in under an hour. Very professional. The job was done with 60 day service warranty (one service recall). My wife was very happy with the job performance.
The cost is high in my opinion at $365/hour. Daniel did tell my wife about the cost/hour upfront and the wife did agree to it. I am open to any correction on my perception on cost since I do not know current typical average rate. My prior data points were that these kind of jobs should be in the $100-150 range, and I am willing to pay up to $200.

This is a great company to work with.
