Get matched with top tankless water heater repair pros in Sunol, 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!"

"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"We noticed black particles/materials on top of our water heater. Our thinking was that the particles were coming out of the top of the water heater, where there is an opening that was just below the venting pipe that leads to the roof. I called Better Water Heaters and Frans (owner?) answered. I did not realize that he was in his truck on the way to another job. I described what we saw and did not think it was coming from the water heater. He suggested that I sent him the pictures that we taken and forwarded to him. Shortly thereafter, he called back and reconfirmed to me that he did not think the particles/black materials were coming from the water heater and that it is more likely, coming from the roof by way of the vent pipe. Frans responded fairly quickly and did not charge me for his professional assessment of the problem. As a result, I will call Better Heater Services in the future whenever servicing is required."

"Jamie is first class. Had my tankless water heater running and provided good advice."

"Same day leaky water heater replacement on a Saturday"

"The cost to replace three natural gas wall heater was slightly less than Gree mini-splits heater cooler. The installers were courteous and professional. Delayed several days as the equipment haven’t arrived yet. Job cost as agreed, but took half day longer due to the complexity of installation. Results are excellent. The mini-split units works as specified. Will use Albert Nahman heating plumbing again in the future."

"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."

"Replaced a filing water heater. The work was excellent. My water heater was basically blocked in by the incoming water and gas pipes, but the two-person team managed to remove the old heater, replace pipes as necessary, and get everything working again. Gave up-front pricing including permit inspection. Super professional crew."

"Very Well - the repair was done efficiently & the technician was able to repair a tub faucet leak under the time constraints I had set."

"Jess and his crew did a great job recently repiping my house, both the water supply and drain lines. Jess is easy to work with and very responsive. His price was very reasonable. He came back promptly to fix some very minor issues I found (tiny leaks from the kitchen sink drain and from one of the outside faucets). Everything is fine now. The sprinklers in my backyard work better now because they're getting more pressure than they got from the very old galvanized pipes that were replaced. I'm happy to recommend him."
