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 called the business at 7 o’clock in the morning and I got a return call by 7:45 AM. Johnny was very professional and courteous and I received my estimate to set a new bathtub within a few hours. The tub was installed with a new P-trap and faucet within the timeframe quoted. I will be using JB plumbing again I’m very happy with the work performed!
Excellent service, quick and informative plus the guys were very pleasant to speak with.
