5 Star Reviews JB PlumbingWhat can I say about the service and the finished job from JB Plumbing? We are so in love with our new kitchen!! What was once a drab and dark area is now the most inviting room in the whole house. They literally gave us the kitchen of our dreams. It began with a service call from a leak that turned into a reno and although that sounds like a nightmare Jesse and his team couldn’t of made the process smoother! Thank you again Jesse, Jerry, Anthony, and everyone else that worked so hard on this project. Jeffrey, you have an amazing group working for you. Your team’s expertise and professionalism is certainly appreciated.

Ryan was friendly and professional. He made sure I understood what he was doing, and why. I’d recommend JP Plumbing to anyone in the area. Thanks, Ryan!

5 Star Reviews JB PlumbingI was referred to JB Plumbing by a friend and found them as a local listing when I discovered a slab leak. They came out within an hour that morning I called to complete a leak detection and provide an estimate for repairs. They did great work right away and even my claims adjuster said it was a great price for the repairs. Thank you to Corey and his crew! They will be my go to for all my plumbing needs.

5 Star Reviews JB PlumbingPlumbing problems are always frustrating. I am somewhat handy around the house and yesterday my shower was completely blocked and wouldn’t drain. After work, I tried several different ways to unclog it with no luck. My attempts only resulted in both showers being clogged. I called JB Plumbing around 8:30 pm and within an hour a very nice young man, Cory, showed up. He was very polite and took a look at the problem and went to work. He struggled a little, it took him about 1 hour, but in the end he was successful in getting my problem solved. The charges for emergency service were reasonable. JB Plumbing is our go to company from now on.

5 Star Reviews JB PlumbingKyle came out to house, because of a slow draining main line to the street. I made the appointment for 2 hours after I called. He arrived on time after calling me prior to arrival.
He snaked the main line to the street, removing a clump of tree roots. After flushing the system, the drain works fine. The price was very fair and competitive for the job done, BELOW what was quoted over the phone.

He explained that the tree roots eventually would clog the line again. He recommended that the drain be viewed by camera and be hydro cleaned and gave me the price. He explained that if the drain was broken by the tree roots it would need to be dug up and repaired, which would be very expensive due to the depth of the sewer line under the front yard.

I feel he was up front and honest about the expenses and he did not try a hard sell, but just gave me the information.

5 Star Reviews JB PlumbingHad a stopped up kitchen sink. Jeff and Brett took care of the problem very quickly. Jeff gave me some suggestions so we could avoid future problems. He also noticed low water pressure so he adjusted the regulator on his way out. Will call them again but hopefully we won’t need to anytime soon.

Update: We had to call after business hours for an urgent plumbing issue. Cory came out within an hour and was able to determine and fix the problem right away. He made an unpleasant experience a lot easier to get through. Will definitely be using them again.

5 Star Reviews JB PlumbingWe are very happy they completed repipe our house. They are professional and job well done and done right. 20 years written contract warranty on the repipe job got my trust in this company. We can be worry free at least for another 20years. I am sure they will still be in business for the next 30 or even 50 years.

~Bob L., Sn Dimas, CA

5 Star Reviews JB PlumbingFast to respond. Price was fair for the quality of work done. I feel confident work was done correctly the first time. Ryan was courteous and helpful to help me understand the situation. Will call again if needed in the future.

5 Star Reviews JB PlumbingJeff and the crew at JB are professional, honest, and time efficient when it comes to any plumbing job. I’ve used their services several times and have yet to be disappointed by the quality of work or the price.

5 Star Reviews JB PlumbingI have used JB for my rental property more than once. They came and did the job with quick response and turn around time. They are very professional and friendly. I highly recommend them and will use them again and again for any property that I own.

5 Star Reviews JB PlumbingI needed a plumber fast to fix a leaky connection on wall behind my new refrigerator. I called JB plumbers and Jeff dispatched Ryan within a hour!! Quick and reliable repair. I will definitely call them again for next repair.

~Lisa M., San Dimas, CA

5 Star Reviews JB PlumbingThe (guys who arrived) worked their posteriors off in order to turn what could have been a very expensive job into something I could afford. I have complete confidence in them. They installed a new clean-out (digging through some of the nastiest, rocky and hard dirt to get to the pipe) and they repaired our vent pipe without having to dig into the slab.

~Shelley K., San Dimas, CA

5 Star Reviews JB PlumbingThis crew did a great job on re-piping our home. Patch all holes made during the installation. Fast, professional  and courteous.
Thanks JB Plumbing!!

5 Star Reviews JB PlumbingI have put off fixing my toilets for a while now but was so happy to meet Jeff. One of my toilets has been down for years and Jeff fixed it without a problem and it now works great! Very friendly and professional. He did a great job and I will be recommending him to everyone I know. Thanks Jeff!

5 Star Reviews JB PlumbingJB Plumbing has always done a great job on the rental unit that I own. Quick to respond – accurate analysis of the problem and professional repair accomplished. Kudos to Ryan & Kyle!

~Smitty P., Diamond Bar, CA

5 Star Reviews JB PlumbingCustomer Satisfaction Guaranteed. We worked with Jeff on our plumbing and he, and his expert team of plumbers, was great. The plumbing work necessitated remodeling due to having to cut into our concrete slab. Once plumbing work was largely done, Jeff turned us over to Jesse who project managed the renovation. Jesse brought in a team of experts to do tile work, flooring and Jerry who is a handyman of many talents who did a lot of work on our home, including some really great wood work and drywall work.

I was very worried about the extent of the work and Jesse assured me that they don’t leave until I’m happy. The team held true to their word and made this nervous homeowner quite happy with the result. Jesse came back personally to supervise efforts and ensure timely completion and quality result! Jeff and Jesse were always available for a consult and quickly responsive to ensure all our home’s needs were addressed. I highly recommend this team of professionals to handle your plumbing and renovation needs!

5 Star Reviews JB PlumbingPin hole Leak Was detected on a late Sunday night. After finding J B Plumbing on line and filing a request for appointment, the phone rang in 5 minutes. (Their guy) was here on Monday morning, found the spot and repaired it quickly and professionally. Asbestos issues, insurance coordination and follow up work was all done expeditiously and professionally. All staff was young, enthusiastic, courteous and competent.
We are very pleased with their services.

5 Star Reviews JB PlumbingWoke up to find a block in our main line. I called on a Sunday around 10:00 and Isaac was at my house knocking on the door in less than 2 hours. He cleared the line quickly and was extremely professional.  Emergency Service without an appointment on a Sunday…I know who I’m gonna call next time I have a plumbing issue!

~Tomas B., Rancho Cucamonga, CA

5 Star Reviews JB PlumbingI work with Jeff and Julie weekly and I find them to be very friendly, useful and hard working. J.B. Plumbing is a true American success story / small business.  Don’t assume they’re small though bc they can handle small, medium and large size jobs. Congrats to Jeff and Julie for running a solid business and for growing in a time when most businesses are shrinking! Their growth is a tribute to their dedication! 🙂

5 Star Reviews JB PlumbingBooking was no problem over the phone for the next morning after determining that my main floor toilets would not drain despite using my trusty plumbers helper.  Yikes!

Isaac was on time, polite and professional.  He diagnosed my drain stoppage and cleared it with a roto-rooter and high pressure jetted water.  We were able to see the blockage on camera.  I would use them again with any future plumbing problems around the house.

~Nathan C., Etiwanda, CA

5 Star Reviews JB PlumbingI called JB Plumbing for a second opinion. Another plumbing company had told me I needed $1,550 worth of work. A neighbor had used this company and recommended it. When I called them they came to my house immediately, which was good because it was an emergency (we couldn’t use showers or toilets).

They confirmed that the work needed to be done, but they charged $250 less than the other company. They explained everything they were going to do, and why, and always let me know when they were starting work, how long it was going to take, and when they were finished.  They were very prompt and the work was done quickly. It’s always painful to have to spend a lot of money. But because they were recommended and because I got a second opinion, I was comfortable that they were only doing what was necessary, and they were charging a fair price.

5 Star Reviews JB PlumbingFinally an honest plumber

JB Plumbing came out to my house at 12:30 AM for an emergency. We had a horrible mess with a toilet that overflowed and flooded the bathroom and bedroom. He was at our house in less than an hour. He was very fair and professional. He even took care of the insurance and emergency clean up, what a blessing this company is

~John M., Claremont, CA

5 Star Reviews JB PlumbingThe best compliment I can give is that they are honest!!!

Great company to do business with. Issac did a great job for us cleaning a sewer line, he showed us where the problem area’s were and what may be causing the problem and he provided multiple options for resolving the issue. I will keep them at the top of my list for my plumbing needs. After dealing with the crooks (my opinion) at another place I was very pleased with the honesty, integrity, and service that was provided to my wife and I. Working in the service industry for over a decade, I know that honesty is the best way to show a customer you care and to develop return business.

5 Star Reviews JB PlumbingThey are terrific, responsive, have effective prices, and are kind.

I have been using J.B. Plumbing for about 8 years, and I really like them. They are professional, timely, get the job done, and are kind. What more reason do you need to use their service?

They have done mostly maintenance and small jobs for us. We got a quote for a larger job, but ended up not going through with it. The work is always great with no problems. You can definitely trust them. They are a great company. They are easy to work with, do what they say, and are professional.


~Kathleen P., Glendora, CA


5 Star Reviews JB PlumbingHonest, dependable, and friendly service.

JB Plumbing is always very quick to come out. Other plumbing companies we have used schedule us out 2 or 3 days, but J. B. is always very prompt. They always arrive on time. They do great work, and are very honest.

We have been using them for 10 years. They have done anything from small work, like unclogging drains, to large jobs, like remodeling several of our bathrooms. They have also done the copper re-piping in several of our homes.

I have recommended them regularly to friends and family. They do excellent work overall. I highly recommend them. You can’t lose with them. They are honest, trustworthy, and it is great service for a great price.
