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

"Water Heater Masters came the same day that I first contacted them and replaced my heater that day as well."

"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."

"Excellent from start to finish. Arrived on time, replaced our old water heater with a new one, left everything very clean and, from what I can tell, provided excellent workmanship at a very reasonable price."

"The plumber showed up within an hour of my request. He thoroughly inspected my tankless water heater and discovered the issue quickly. Problem solved. I would definitely hire the personable and efficient plumber again."

"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."

"Oak called 2nd but came next day/ UN-prepared to do either repair or water test (requested on phone) or even replace with ready new ADA toilet that the lying receptionist booker said they have “some in stock and if not he will show a catalog of choices”. Guy came punctually with Nzo tools or appliances Or knowledge of what I asked for as an “URGENT repair/replace”. See ABC review same call. Not quite as bad as them doing same since we also still have broken HVAC too, both said they would fix ( I bought gasket already, they could have put in) or replace if they brought new toilet. Problem is not in water pipes except they need testing for lead - both said they would do this too - when I asked oak re taking a sample, how long sitting in pipes? He wiped off his soda water bottle and asked “which pipes?” !!"

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

"My experience with Alex and Pedro was great. They were on time, fully prepared, and did the job very well. Thoroughly tested all endpoints to make sure there were no leaks. Communication throughout the entire process was superb, I was well informed on everything that was happening at all times throughout the project."

"It went very well; the thorough HVAC system checkup revealed some questionable component that were best suggested to be replace with new ones. I am not confident that my HVAC system is set for more that good performance going forward. I appreciated the non-pressured advice and suggestions in coming to my decisions. Thank you, Joaquin Ortiz."

"Michael Smith gave us a very excellent service. Weâ re so happy to have him fix our big problem with the water leak infront of our house. He has really a great knowledge and the best quick service performance.. We truly appreciate your help. More power to the company!"
