I have had two separate business dealings with this company and both occasions were great. They are honest and always available. I can attest to the other reviewers here who claim they work nights and/or weekends at no extra expense.
The first time I hired them I needed both water heaters replaced in our house. Not only did they come out and actually do the work the day I called for an estimate, they upgraded my heaters at no charge to me. When he told me they would come out and replace them at 5 pm on a Tuesday it was because he knew I have three small children at home and he didn't want us to go without hot water for several days.
The second time, I called someone else hoping that they could deal with both irrigation and plumbing as I was not sure if was a leak at a spigot or a water heater. The other company I called never showed up. I decided to call JR's since they did the work on the water heaters. Within one hour of my call on a Friday afternoon (4 pm) Jason arrived and discovered it was actually a pipe running from one of our AC units which went under the water heaters. He charged me a standard "come and see" fee and fixed it for me.
I would recommend JR's plumbing without hesitation. Yes, there are bigger companies and maybe even cheaper (doubtful) companies around, but I have not found many companies in this area that provide such great service. Accessible, reasonable, pleasurable, and swift.
Great company even better service, I wish you all the success you deserve JR's Plumbing! :-)
