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!"

"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 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."

"Boden Plumbing was able to send a team over immediately and they worked diligently to correct the problem....nowhere near as easy as they thought upon arrival."

"Had to completely repipe with PEX due to rotted pipes made in China. Ebert and his team did a great job and were very professional. Even the sub they brought in for the sheetrock work was great. Recommend!"

"We chose BeastBay Plumbing for a complete home repipe after meeting with several companies. Ron Buris and Jovon were professional and promised great service, which is why we hired them. I requested the work be permitted. The crew worked hard, but cleanup could have been better. Unfortunately, the day after the job was completed, a newly installed pipe behind our chimney leaked, soaking our brick fireplace. They repaired it, but it leaked again a couple of days later, causing more water damage. We had to shut off our water and went without water until Monday because no technician was available Sunday. I was told someone would bring fans to dry the area, but no one came, so I rented them myself. The city later failed the inspection, requiring additional corrections. We paid quite a bit for this project. After final payment, communication became very poor. I expected better follow-up and accountability for a job of this size."

"Marcell is a true professional. He is prompt, honest, accommodating and his work is top notch. Marcell bailed me out when I needed my hot water heater replaced. He was very helpful in answering my questions over the phone. He called back in a timely manner and made sure to confirm all appointments. I would recommend him in a heartbeat."

"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."

"Went above & beyond in service. Got the Furnace replaced, brought space heaters for the occupants, Got it done quickly & left no mess. Redid the duct work and worked well with the occupant. Thought this type of service did not exist anymore. Was pleased how quickly Furnace was replaced ."

"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?” !!"
