Recommended Customer Reviews

Finally got to the kitchen remodel after years of waiting. With the remodel came the need to move the sink supply lines and waste, as well as the gas line. I have had J Hart plumbing come out for a couple service calls and was always impressed with the employees, work ethic and cleanliness. I called and Jay came out in short order, assessed the job and gave me a bid. With an obviously fair bid and their reputation I decided I did not need to contact anyone else. There was a little prep work I needed to do so Jay said call when it was completed.
I contacted the business and within a week Sal and Adam came out on a Friday. These guys did great work! It looked clean, solid and professional. These guys worked through lunch so the job could be done the same day! Thanks. They even put up with my three dogs pretending to be safety observers. If I ever need plumbing work or service again J Hart will be the first call I make.

We had a small problem with our kitchen faucet, they were very professional and were very polite... they corrected the problem and were very efficient! I would recommend using this company for all my plumbing needs!

Excellent service. They were able to come out and fix our toilet within hours of calling them. Thank you

Having observed many contractors in the past I can tell Jay Hart does very high quality work, they are honest and offer fast response.
Our water heater died. JHart came to evaluate the situation and install a new one on the same day I called. It was a tricky install like in many old cabins around here. Our heater is in a tight crawl space, but they got it all done in a couple of hours including bringing the piping up to code.

We called J. Hart Plumbing yesterday afternoon and spoke with Robert, who was professional, kind, and sympathetic to my 89 year old mother. We had just had a new generator installed and when the electrician went to start the gas back up the starter wouldn't work, so no hot water. Robert sent a plumber out who was literally here within 10 minutes! Instead of trying to sell us a new water heater (even though ours was 13 years old), they tried to repair it, then tried to find us the parts needed (for an old WH), but could not. So ultimately we purchased a new one. Johnny Hart and Dad came out this morning and replaced it for us. SO efficient, SO timely, SO nice! What a wonderful company to work with! If I could give them more than 5 stars, I would! I would not hesitate to recommend this company!
Thank you J. Hart for coming to our rescue!

Loved that they showed up wearing a mask. The technicians Bobby and Octavian were professional and promptly figured out what exactly needed to be fixed. They walked me through everything that was being fixed step by step and even went above and beyond. They noticed that the caulking needed to be filled in and just took it upon themselves to fill it in. I've struggled with finding reliable service in the Arnold area and this company exceeded my expectations. I'm extremely satisfied and glad I found them. I highly recommend this company!

J Hart is simply an outstanding company to work with. I used them a couple of months ago and the entire experience was great. From calling to initiate the service call to the guys showing up for the work, I found them to be nice, sincere, and very professional.
An absolute gem of a company here in Sonora.

Our Tech Brian is the best of the BEST! Great customer service. Trustworthy!

I had JHart come out and do the under slab plumbing on the house I am building. Talk about a good company! Buddy came out on a Saturday with 4 guys and got everything plumbed in one day! This company is at the top of their game! I had some concerns about the tub traps and communicated that to Buddy, and he sent a guy out the day the foundation was being poured to make sure nothing got misaligned before the concrete was poured. I have been in the building trades for a really long time, there are not many companies out there that are performing like JHart is. If you need a plumber that is highly efficient and follows through on his word, CALL these guys! Very helpful, and very knowledgeable. They communicate clearly and they really hustle. I can't say enough good things about my experience with this company!
