Recommended Customer Reviews

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!

New to our Sierra foothills community, we ask friends for service provider recommendations.
J. Hart came highly recommended and now have ours.

Called and Jay got back to me right away!! Took a few photos of the existing Hot Water heater that was at least 25 years old.
Got 3 price and Jay was in the middle. Next morning the 3 man team showed up. Relocated the heater and had it up and working in 3 hours.
Great Family Business!!!
They will always be my first call
