    Quick response and a reasonable price. No extra charges as it was an easy repair as it was just snaking a drain.

    After PG&E shut off the leak, we called Tiberio who dropped everything and was out to help us within an hour.

    I couldn't recommend Dan's Plumbing more highly! We had a surprisingly high water bill and couldn't…read morefigure out why our water usage had suddenly increased, so we called Dan's to help us troubleshoot the problem. The technician they sent was incredibly nice, professional, knowledgeable, and genuinely helpful. He took the time to explain what he was finding, answer all of our questions, and share helpful information about our home's plumbing. He was excellent at troubleshooting and methodically tracked down the source of the leak. He not only found the problem, but was able to repair it for us on the spot. If you suspect you have a leak, I would definitely recommend calling Dan's Plumbing before going straight to a specialized leak-detection company. The front office was also fantastic. They were responsive, helpful, and kept us updated with text messages throughout the process, which made everything so easy. It's rare to find a company that combines great service, expertise, responsiveness, and genuinely good people. We had such a great experience with Dan's Plumbing and wouldn't hesitate to call them again. Highly recommend!

It was a blessing Tonya helped me arrange an appointment on Tuesday but called back later when there was an opening for the day of on Monday! I then met Rick Martin who was a very patient and thorough technician, who explained what the plan was, and depending what the problem how he was going to combat the issue. I'm a complete plumbing nincompoop so I appreciated how Rick answered all my concerns. He was swift with his work and did a very clean job. Thank you so much team at Dan's plumbing!

    Our chrome p-trap failed and I attempted to replace it myself. There were further signs of…read morecorrosion in some other pipes and still a small drip, so I wanted to have a professional take the next steps. I was given an accurate 2 hour arrival window and got a text when Noah was dispatched, about 15 minutes before he arrived, which was helpful. Noah was great! He gave me a quote up front and there were no surprises. He showed me the additional issues that were not fixed by my simple replacement, and when I asked questions he offered to teach me how to do the larger replacement myself. He was patient and walked me through all of the steps including a thorough check. He showed me where there was still moisture after his initial install, walked me through his troubleshooting, made an adjustement, and ran another thorough check. The whole thing took about 30 minutes, and I am now confident I would be able to do more if not all of the replacement on my own. I did not expect the whole thing to be fixed so quickly, and have never been invited to learn what to do! I am so appreciative of Noah's friendly patience and efficient work. I will definitely use this company again.

    I scheduled an appointment through Yelp and no one showed up. It turns out they use an automated AI…read moreto schedule appointments. I took the morning off from work to meet the technician only to learn that the appointment has not actually been scheduled because I did not answer the question, "are you the home owner." I took the morning off and wasted my time because of this automation. I'm sure they're a great plumbing service if you can actually get hold of a real person, but I'm so angry that my time was wasted. ***UPDATED SAME DAY*** This company reached out to me to let me know they just started using Yelp's AI messaging service. My issue is with this service and not with the company necessarily, so I updated my review and increased my rating from 1 star to 3 stars. I appreciate that a real person found me and reached out by phone and text. I am waiting until our actual appointment in 2 days to speak to a real person before I add any further stars to this review. ***UPDATED AFTER ESTIMATE VISIT*** I ultimately did not go with these guys because of their pricing, but the fellow who came to my house was incredibly nice and had been sent with a message from the main office to apologize profusely and provide the best service possible. This company really cares about their customers and their reputation. If I were just a little bit richer, I would be able to choose my service provider based on kindness and not just price alone. But for now, my budget dictated that I go with someone else. From this last experience with them, I highly recommend! (But still hate that AI, Dave, that answers their Yelp messages)

    Tried to make an appt after hours via the app but it was a big hassle so I decided to wait and call…read morein the AM. I was then contacted by text by a robot masquerading as a human offering to help me make an appt. I stupidly made the appointment. What followed was tons of phone calls purporting to be from the business (the robot told me to ignore if I wanted to keep my appt., so I did). Finally they got through to me, explained that they are using AI (and not training it for the job) and so the appointment it made me, the price it quoted me, and all the info I gave it were not in their system. In addition, the appt was scheduled for a time that is not available and the price was incorrectly quoted. I had changed my schedule to accommodate the original appointment time and now this human wants me to change it all back cause they gave the call to a robot who gave me an appointment at a time not available? I spent over an hour trying to set up this appointment between the calls and texts and ended up cancelling. I just need a filter cleaned on a mini-split. Shouldn't be this hard. I don't do business with companies who are too lazy or too cheap to answer the phone but rather let robots incorrectly give out information to customers. Life is too short. There are plenty of plumbers around.
