I was really impressed by this plumber and will use next time! When I called, they were very nice. They able to explain what might be the problem and they gave me an estimate over the phone. They were able to come out the next business day. The plumber was knowledgeable and honest. The price was reasonable . I would definitely recommend them!
Tom E.Just got my kitchen remodeled.
I needed my new garbage disposal installed.
Got a price over the phone. And they didn't charge me more once they got to my house.
They said they were going to be here between 2-4pm the next day.
They were not only early 11am, but (Ramon) was clean, neat, fast, and easy to work with..

Buyer beware. I was charged a $125 fee to come out and look at my water heater which would be applied to the repair if I use them. They ordered the warrantied part and I was to pay a total of $175 for installation. The water heater still did not work so they now told me I needed a new water heater which was under warranty. But I must pay for the repair they did that did not work. They charged me an additional $1057 to install. Never crediting me the $125 towards any repairs. In all I was charged $1182 for them to install a water heater. Not to mention I was without hot water for almost 2 weeks while they ordered parts before deciding I needed a new water heater.
Carla Y.I appreciated their patience and professionalism. Also they took the time to give me tips on how to maintain the work that was done. I would definitely recommend.
Thank you Big John's Plumbing of Riverside for your speedy attention, dedication to detail and honesty.
It happened during a 16 hour power outage, our water heater died. Not sure if it was the power outage or the fourteen years it's been doing a great job of heating our water. Our son is a contractor and recommended we call Big John's Plumbing in Riverside. It was Saturday so we called and left a message. Someone at Big John's Plumbing called on Sunday morning and we confirmed that the repair could wait until Monday morning. Mr. Ramon showed up Monday and worked for three hours+ to replace the water heater. He ran into several non-compliance methods used when the original water heater was installed. He revised and installed the correct connections and insured we were up to code. We had hot water an hour after Mr. Ramon's departure.
We would recommend Big John's Plumbing, for any of your plumbing needs, I'm sure, but especially if you are in need of a new water heater. They've got you covered.
Chris H.I would like give a big thanks to big John plumbing and my plumber Ramon who came out and fix and my bathroom. He was very professional, patience, and more importantly fix the problem. Thank you again.

A special thanks to my Technician, Adrian for his knowledge, professionalism and he was super courteous! I rarely trust people coming into my home but when he looked me directly in the eye, I knew he was trustworthy. Thank you Big John's Plumbing-Riverside.
Linda S.Big John's plumbing was quick to respond very efficient with what needed to be done. They were also extremely friendly from start to finish. Very professional and I would highly recommend them!! Thank you Big John's Plumbing!!
Sheila C.Many thanks to John Hernandez, owner of Big John's Plumbing. Ramon, from his company, came out yesterday and replaced our pressure regulator, which showed over 100 pounds of pressure. This was dangerously high. Now, it's at 60 pounds, which is in the safe range. Based on another quote we received, we got a very good price, too.
Another neighbor also had dangerously high pressure, which they did not notice until the water line behind their refrigerator burst and caused thousands of dollars of damage to their home.
They are the best.Havent been disappointed yet.Response time right on and pricing great. Will use again.
