Over the last 10 months we’ve remodeled the entire house, including two bathrooms and a kitchen. All of the plumbing work was done by Shaun at JB plumbing and I wouldn’t hesitate to use them again and recommend them to anyone needing plumbing work done. They are experienced, do excellent, high quality work and all for a reasonable price.

I've been in my home for over 50 years and have had a number of plumbers, JB Plumbing is my far the best I have ever used. Fair prices and excellent work from a nice religious group. Thank You and God Bless.

We have used JB Plumbing for smaller jobs and have been very very happy with the work, they were the only company we considered calling when we found ourselves in major plumbing situation. We, unfortunately have had other plumbing issues and used different well known plumbing companies for which the work was good.…

Very professional, helpful, friendly, and honest with great reasonable prices. They did a great job converting a 3 handle shower valve to a single handle, and added free services as a courtesy.
