    Relocated 10 sprinkler heads and fixed a cracked bubbler riser. Excellent work and post-job cleanup. Date of service 2/09/17.

    John is a very nice guy and repaired a valve for us on short notice. Great job. Will be using them again if the need arises.

    Do you extend existing piping and do you replace timing boxes in the garage?

    Yes, we do both of those things. Anything sprinkler related we take care of.

    Cali Rooter & Plumbing is my new go-to company for reliable plumbers. They answered my call and…read morewere out the next day to take care of a couple bathroom issues. The technician diagnosed the issue on the spot, gave me a price, and completed the work in 30 minutes. They showed up on time and performed with no incident or delay. I would suggest this company to anybody for any plumbing or drain needs, and I will call then first next time I have any issues!

    My sister recommended I do a sewer scope "just in case" since she encountered some costly issues on…read moreher property that could have been prevented with a sewer scope and preventative work. I reached out to a bunch of companies and went with the cheapest (not Cali Rooter and Plumbing) since I figured they'd all be doing the same thing and I didn't expect them to find anything. Well, to my unpleasant surprise, they told me that I needed a new sewer pipe from my property to the street. Despite the fact that the entire plumbing system had been overhauled five years earlier as part of an extensive renovation and all the new plumbing was okay, they had connected everything to the original pipe from the 1940's. They showed me some blockage that was already happening and said that if I didn't replace the pipe I could have an issue with water backing up into the house, causing damage. Given that this was no longer just a sewer scope, I did some more research and based on reviews, asked Cali Rooter for a second opinion. They came out first thing the following morning (like 10 hours later) and told me that I not only needed to repair the sewer pipe, but I also had to get a liner. They suggested that the other company was either negligent, or knew that I needed the liner and was going to wait until the trench was dug already and I was forced to say yes to the upsell. Cali Rooter said that they could come as soon as the rain stopped, about 4 days later, to do the entire repair. Communication was great throughout, they showed up around 9 am and were done by around 3 pm and it looks like they were never there (my biggest concern was the landscaping). They also serviced the two water heaters on my property as a courtesy. All around great service - great communication, fast responses and service. So far so good with the new pipe, although I guess if they did things right, I won't know until after things don't go wrong for decades.
