On a Roll Plumbing was the company sent to my home as a part of my AHS home warranty. JJ, the owner/operator is incredibly friendly, knowledgeable, and professional! He took care of several plumbing issues for us in the same day and did an absolutely fantastic job!!! This is the plumber you want coming to take care of you if you are having issues in your home!
Response from the owner:Thank you for your five star review, Paul! The On A Roll Plumbing team is incredibly pleased to hear about the wonderful experience that you had with our team. Always here if you need us!
My experience with JJ was hands down the best i've ever had with a plumber. We had an issue caused by Atmos that resulted in a small gas leak in our attic. He showed up on time and promptly corrected the pipe. I believe the best part of this experience was the customer service and follow through. He spent a great deal of time ensuring that the City made it out same day, within hours, to inspect his work, which passed with flying colors of course. Once the city inspector approved, he was diligent in ensuring Atmos had been back out to restore service. I had paid him for his services, but he did not stop the work or follow up, which I absolutely appreciate. We have some future work we want to do with home renovations, and he is absolutely going to be my first call when it comes to anything plumbing related. Customer for life right here!

Google asks the price I paid for services, I would like to note this included City inspection fees which are not light, so it is not indicative of the cost to repair a leak.
Response from the owner:Justin thank you so much for taking the time to leave an outstanding review for JJ. The On A Roll Plumbing team is grateful for your business and support. We look forward to taking care of your future plumbing needs.

When water starts leaking under your baseboards, it’s not a “small issue”… it’s a full-blown nightmare!

That’s exactly what we were dealing with until JJ Jacobs from On Roll Plumbing showed up.

From the second he walked in, this guy was on a mission. No guesswork. No wasted time. He literally smelled the problem, opened a precise hole in the wall, and locked onto the source like a heat-seeking missile.

This wasn’t luck. This was experience.
The kind of experience you can’t fake… the kind that only comes from years of being in the trenches solving real problems.

And here’s the part that separates JJ from everyone else:

He didn’t just find the leak (which, honestly, 99% of people would’ve missed)…He fixed it immediately, efficiently, and with total confidence.

Problem identified. Problem solved. No drama.

On top of that, he gave us solid, no-BS advice so we actually understood what happened and how to prevent it moving forward.

Bottom line:

If you want someone who’s going to show up, think fast, act decisively, and get it DONE the right way the first time… JJ Jacobs is that guy.

Easily one of the best experiences we’ve had with a plumber in years.
Response from the owner:Chris, thank you so much for taking the time to leave an outstanding review for JJ. The On A Roll Plumbing team is grateful for your business and support. We look forward to taking care of your future plumbing needs.
JJ Jacob’s was absolutely fabulous. Took care of our issues and in the most efficient way to save us as much as we could. They were extremely friendly, helpful, and professional. We will definitely be calling and recommending them again for any plumbing needs.
Response from the owner:Jacqueline, thank you so much for taking the time to leave an outstanding review for JJ. The On A Roll Plumbing team is grateful for your business and support. We look forward to taking care of your future plumbing needs.
