Get matched with top tankless water heater repair pros in Benicia, CA

"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!"

"Everything went ok as far as I could tell, but yesterday a plumber told me the gas line was not large enough and that is why the water heater is not working properly."

"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."

"They fixed a major water leak and installed a new water heater all in one day. They were prompt and did a neat install. I can recommend them."

"Jared showed up and wasted no time in doing two things at once (draining the hot water heater and repairing a small fireplace gas leak). He educated me a little on what he was doing which is always helpful. He was also careful to keep his booties on, so as not to ruin the shiny wood floors. Highly recommend based on this experience."

"The technician was supposed to be doing a plumbing inspection and draining the water heater. My wife was home; the guy was at my place for a total of 20 minutes and did not say much, then left. I wanted to talk with him about what he saw and some possible things to work on, but he just gave my wife the invoice and left. I am not an expert in any way, but I would think it would take more than 10 minutes to drain and inspect the water heater alone. But I would not know since I was unable to speak with him. "

"They quickly provided one day service call, and fit our repair into their busy schedule."

"Everything was great, and did not let over 100 degrees in garage or a huge spider at the water shut off keep them from getting job done right. So pleased with job, I hired them to do another, that has been needing done for decades, and they were smart enough to let me know they could finally take care of it. Hire them, real nice, professional, very knowledgable and actually left the area cleaner than when they started."

"I didn't watch the technician closely., I didn't want to be in the way. .The technician was determining if the water heater was causing the particle deposits in my water pipes. It was determined the water heater was not the problem."

"Gray plumbing did a great job. Brandon, Andrew and Eric worked so hard to ensure that the work they did on our house is great and to our full satisfaction. They are all very professional and hardworking. I will recommend them and the company they represent to use for the plumbing needs anyone need done in their home. Thank you!"
