Get matched with top tankless water heater installers in Pinole, CA

"I called and they were here working 48 hours to install and haul away a tankless water heater. They did finishing work and completed it to my high standards. They communicated very well as I was uneducated in this area. I highly recommend them."

"Water Heater Masters were top-notch! I called on a Saturday afternoon - they were available 9am Sunday morning to come and inspect and quote. They only had one guy working that day, but scheduled me for Monday morning between 8 and 9. At 8:15am I got a call with an ETA of 8:45, which was a really nice touch! Despite telling me it would take an entire day to install, they were done by 1pm. They also found some creative ways to do the install to avoid drilling through my stucco (for the exhaust vent and for the condensate run-off). Very professional and clean-looking install. These guys may not always be the cheapest around, and they recommended a top-of-the-line heater (which is what I really wanted anyway), but I'd much rather pay a little extra for that level of service and support. Thank you!"

"We are incredibly grateful to Pedro Galvan and his team for stepping in during a moment of urgent need. When our hot water system suddenly failed, leaving us without hot water for daily essentials, Pedro responded with a level of professionalism, clarity, and compassion that is truly rare. From the very first call, Pedro was attentive, transparent about pricing, and committed to solving the problem quickly. He provided us with the most cost-effective and honest quote out of several we obtained—and, even more importantly, was able to come almost immediately when others could not. His workmanship was precise, efficient, and tidy. It was clear we were in the hands of someone who genuinely takes pride in his craft. In a world where so many service professionals overpromise and underdeliver, Pedro Galvan delivers exactly what he promises—and does so with warmth, integrity, and a deep respect for his clients. We recommend him without hesitation to anyone needing plumbing services."

"Water heater went out and decided to go with tankless. Ron is great. Quick response. On site same day. Smart. Gave me proposed costs and answered any questions. Matt did the installation. Great work. I will use Beastbay again. No doubt about it."

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"Jose was professional, punctual and efficient. He came prepared to complete the job, explained exactly what would be done and his estimate for the services was 'on point'. I would highly recommend J Comparan Plumbing. In addition, when I went to Daly City to obtain the permit, he was kind enough to come to their offices to obtain the license to perform work in Daly City. Had he not taken this extra step I would have lost a day while I searched for someone who Daly City would allow to complete the work. His personality was engaging and made the entire experience enjoyable. Because the work involved safety, he was careful to explain how the safety features worked and how to handle the water heater in case of emergency. Because my daughter will be living in the home it is important that she is safe. After this work was done, I have every confidence she will be."

"I had a great experience with them. They did a tankless water heater for a fair price and helped install new water lines for my espresso machine in my cafe. Would recommend to anyone who needs the job done right!"
