Get matched with top tankless water heater installers in Napa, 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!"

"Perfectly. They cleaned everything up, explained how the system worked and how often it needs attention, and hauled away the old hot water heater. They arrived on time, worked steadily, and finished before dinner time."

"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."

"Had an excellent experience. My water heater went out on sat , he came that same day and it was replaced first thing Sunday. Couldnâ t of been easier, very polite and professional. They also made sure to clean up and made sure my carpets didnâ t get any water as they removed the broken tank. ð ¯would hire again and recommend."

"My water heater went out so we decided to call True Blue Plumbing Co. I’m so glad we called this company. Very professional company. The repairman was here in less than three hours. He replaced the pilot light assembly and now no more cold showers. I would recommend True Blue Plumbing. The cost of the repair was reasonable considering a new Hot Water Heater. Prompt and friendly service."

"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."
