"Perfect! I called Western Rooter the AM my disposal went out. They were at the house the same day, at the time they stated they would arrive. The work was done efficiently and professionally and completed within an hour. I have called on Western Rooter for many years for various plumbing needs (clogged drains, replace water-heater, replace main water line, etc.) and have always had great, timely service at reasonable $$$."

"Unfortunately there was a defective fitting that caused a pipe to burst. The house was vacant so we didn't learn about it until the next day. Alvin bent over backwards to repaire the damage, replace the ruined water heater, and make us whole. He even changed the water heater to a tankless model because the location of the ruined water heater didn't meet code and tankless was our only option."

"Chad was very helpful. He found there was a simple repair needed for our leaky faucet. My husband was glad we didn’t need to replace the faucet. Price was fair and job was completed in a timely manner. He offered to do a free plumbing inspection and found our water pressure was high and recommend to replace our failed pressure regulator. I’ll be calling them back for the refulator in the near future!"

"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."

"My family recently moved Fresno. When we lived in LA we hired Johns Plumbing to install a new water heater. It was 40 gallon Bradford White water heater. John gave a free estimate first. Then his team installed water heater. Victor and his helper worked fast and accurate. We highly recomend Johns plumbing"

"RCâ s Plumbing is absolutely the best! Robert, the owner of RCâ s Plumbing, replaced a leaking 75-gallon water heater (with recirculating pump) just yesterday and his quality of work from start to finish was truly superb! His attention to detail and thoughtfulness throughout every step of the project, including the mitigation of mold and reinforcing the raised platform that the heavy (approx. 620-lbs, filled) water heater sits on, is honestly second to none. Something that I also appreciated and valued about RCâ s Plumbing and Robert is how he takes his time to answer any and all questions about the project, both during and after the project. After completion of the project, Robert summarized everything that was done, showed us how to operate the various components (e.g., new valves, gas sediment trap, pressure release valve, etc.) and also shared information about maintenance of our new 75-gallon water heater and registration for warranty. Robert and his technician assistant (his son) also cleaned up the entire work area before leaving. My wife and I could not be more happy! One final but very important noteâ there are many other plumbers out there competing for your project. When it comes to a water heater replacement project, whether it be a common gas water heater with tank storage or a tankless gas or all-electric water heater, many plumbers only offer a specific brand of water heater they like to install. You donâ t really get a choice. With Robert and RCâ s Plumbing, I received an entirely different and genuinely appreciated and valued experience that many other plumbers would not provideâ being able to choose/select the make and model of the water heater you want for your house without paying an inflated price for the project! After doing some research regarding the make and model of water heater I wanted for my home, l shared the information with Robert. He was completely respectful and open to my choice/selection of water heater and without hesitation, agreed to call the plumbing supply houses he normally use to track down the water heater I wanted. When he learned the local supply houses did not carry the specific model I sought, Robert did not hesitate to special order the specific model for me. When the water heater was delivered to RCâ s Plumbing, Robert called to schedule the installation appointment. As stated earlier, my wife and I could not be more happy with the completed project. We highly recommend RCâ s Plumbing without hesitation for all your plumbing needs! Thank you again, Robert, for the super job and you will have us as customers for life! Tom"

"My water main went out on Christmas Eve leaving me without water, Wes offered to come out on Christmas day to make the repairs. I told him we could wait until the next day, he arrived on time, dug up my very rocky soil to get to the water main and made the repairs. The customer service was great and he explained everything to me every step of the way. The cost was also reasonable. I have asked that he return to make an additional repair later this week. He definitely has a repeat customer."

"As expected, I got bombarded with several texts/calls/Angi messages as soon as I requested a Water Heater replacement. I waited for a human to leave a message instead of automated systems, which was Paul at Complete Plumbing located in Claremont. Same day replacement, haul away, and install of a 40 Gal. Bradford White was $1595 (2 year labor water, 6 year manufacturer warranty). Michael did the installation and had a delay from the first job, but Paul kept updating status and the install time wasn't much later than the original estimate. Michael answered all my questions and concerns."
