Great experience repairing an outside faucet at our home.
The staff at JB Plumbing are great! We had a plumbing issue arise late on a Friday and they were quick to answer their phone and sent a team out the very next morning.

Amazing Company - reliable, efficient, trustworthy.
Prompt and Fast Service
Very impressive professionalism by JB Plumbing, Cory was punctual & did a great job. Even got the “Dad” inspection & seal of approval during the install by my father in law. Would highly recommend.
Showed up on time. Very friendly and helpful. They went above and beyond by taking care of an extra plumbing problem that was not part of my original request for service. BIG THUMBS UP to JB Plumbing!
We had an issue with our primary bath at 11pm and called JB Plumbing. A dispatcher answered and although they could not come that evening they came the next day between 8-11am. Cory arrived and was great. He was very professional, explained the issue and was able to replace and fix the part, Re-seal the part and…
Good guys honest. Friendly
Flume detected a leak, so we called another plumber to come out and help us find it. $200 later and two holes in my laundry room later, they found nothing and kept trying to upsell me on a pressure valve regulator and repiping my whole house. Called JB plumbing that afternoon and Johnny came out the next day. Took…
I can't speak about value bc after talking to Johnny who was very professional and responded instantly, I didn't get another quote.
We had a great experience using JB Plumbing, responded quickly to getting us hydrojeted for our grease pit. Thanks Cory for your help
Excellent service and response time in fixing our irrigation system. We had a leak and Johnny was able to identify and recommend repairs needed. Very satisfied with the work done.
I had a gas leak in the main line from the gas meter on the curb to my house. The gas company threatened to shut off my gas service immediately, but after some discussion gave me 72 hours to have the problem fixed. I called JB, and they came to my home within 30 minutes, and gave me me a reasonable estimate. I gave…
I suspected a slab leak which was confirmed by JB Plumbing. They immediately put together and explained the recommended proposal of re-piping the house. Since this was the third slab leak in the house over the years, decided this was the way to go. Johnny and his team were professional and very capable during all…
I don't like to leave bad reviews but this company definitely deserves it i paid them 3500.00 to fix a leak and they made it worse cutting into my spinker lines and added to the problem i would definitely not recommend them and trust me when I say this to anyone looking to hire a plumber stay away from this company they are terrible and dishonest
