 Trustindex verifies that the original source of the review is Google.  James and John did a shower install for my master bathroom. They did an excellent job!! They worked consistently and were highly professional. Very kind men. Also, they made sure to clean everything up before leaving. As a single mother,  I was very comfortable with them in my home based on their professionalism. Overall,  I am very happy with this company. I will continue to use them for any future plumbing issues I may have.

 Trustindex verifies that the original source of the review is Google.  I don’t normally write reviews, but I couldn’t not in this case. I can’t believe any of this even just happened today. So my water heater was acting up, couldn’t keep the water hot more than a minute or two. I had another company come out this morning and they told me I would need an entirely new unit, they quoted me $5400. I was super bummed because who has $5400 laying around. A friend of mine recommended James at JHS. I spoke to him on the phone for a bit, he said that it was possible that the part that sounded like it was broken may be under warranty. He came out same day, was here about 2 hours, and was able to completely fix the problem without even needing to replace any parts. Cost me $400 out the door. $5400 to $400. For one thing, I’m very upset that the other company was either trying to con me or else is completely incompetent, but regardless I am so very thankful to James for not taking advantage just because I don’t know anything about water heaters. I can’t believe he saved me $5000 today!!!!! Thank you so so so much. Could not recommend more!!!!

 Trustindex verifies that the original source of the review is Google.  James came to my house for a service call and quickly fixed the leak I had in my bathroom. He also fixed a problem I was having with my dishwasher. He was super respectful and professional! I will definitely use JSH Mechanical again in the future.
