Leak Detection
Our expert plumbers use advanced electronic leak detection and video inspection technology to precisely locate slab leaks, gas leaks, and hidden water leaks. With over 37 years of experience, we guarantee accurate diagnosis and repair of all plumbing leaks without unnecessary wall or floor damage. Our state-of-the-art equipment ensures minimal disruption to your property while providing permanent solutions for residential and commercial properties.
Hydro Jetting
We employ high-pressure hydro jetting systems (up to 3,000 PSI) to sewer lines and drains of roots, grease, and debris buildup. This eco-friendly solution effectively clears clogs and restores optimal flow in residential and commercial plumbing systems. Our technicians use specialized nozzles and 600-foot hose reels to handle even the most stubborn blockages in pipes up to 8 inches in diameter, providing long-lasting results.

We specialize in complete copper repiping and PEX installation for homes with aging galvanized pipes. Our expert team handles both slab foundation and raised floor systems, using American-made materials that resist corrosion and improve water pressure. We offer trenchless options and minimize drywall damage during installation, with professional patching included. Upgrades include tankless water heaters and earthquake-strapped systems for enhanced safety and efficiency.

I was doing my own do it yourself water heater repair and found out it was beyond my scope of repair. Called up JOHNNY immediately came out and All they had to do was look at the problem, assess it, and he immediately knew what to do. The price was very fair. Both of the gentlemen were very courteous and kind. I would highly recommend them

Aaron did a great job removing and replacing our toilet in the master bathroom. He was able to work through some wrenches that were thrown at us in the process. He ensured we were happy before he left. He was also very good with my kids throughout the whole process with all of their interruptions. I wanted to make sure someone gave him a pat on the back for his persistence and hard work. Also the top three price quotes we received for the scope
Of work. Highly recommend them thank you again!

Our toilet was clogged on a Sunday morning. 8 people in the house. I called and they don't do weekend visits. We have been a repeat customer and a wonderful guy showed up. Couldn't fix on Sunday but Aaron showed up on Monday and fixed the issue. The employees are always nice. In and out. Easy and great business

We had a pinhole leak in our copper pipes. Tried calling another company but they wanted $125 just to show up in a week. I called JB plumbing and they could come the same day without a show-up fee. (They actually fixed our leak that same day.) Johnny and his team showed up with masks and booties, fixed our problem and they were very respectful/ professional. This is my third pinhole leak in 15 years and Johnny and I discussed a Pex repipe. Work was started and completed in three day. I recommend them 100%. Also they found a small gas leak in my attic and fixed it with no charge. Going the extra
