"I returned home from a trip and found water all over my downstairs bathroom and adjoining shed. It was late afternoon and I called Western Rooter who agreed to come out first thing the next day, I had a pretty sleepless night. Rene showed up the next day and assessed the situation and started clean up. Tony soon joined him and the two worked all day until after dark and helped me with cleanup and putting things right. They explained to me what they were doing and why along the way. I felt they charged a fair price. I am so grateful for their service and highly recommend Western Rooter."

Backing up? Got roots? Blast those roots out with a Hydro Jetter! We use a wart hog nozzle that combines controlled rotation with a unique 8 jet cutting configuration optimized for removing roots. It’s better with a jetter! Call us! We got this! ??

"The plumber spent a lot of time just trying to figure out the source of the hidden leak. He had a lot of patience. The quality of work was good as was the price. I would definitely hire them again."

"David sold this water heater replacement job to me with his knowledge, professionalism, kindness, and accuracy of what to expect. Jose is a fantastic installer. After he finished, he took the time to explain to me what I needed to know to operate the water heater. I did get cheaper bids but for the money I spent this group was the right call for me. They went above the call of duty to make sure everything was handled correctly. This includes the verification phone call. Thank you young lady."

"Mr. Joe was not only professional, but personable as well. He identified my issue with my hot water heater, and fixed it expertly. Dr. Rooter treated me with respect and was overall a tremendous value. I saved the number, as Dr. Rooter is now my first choice for my plumbing needs. 10/10"
