Get matched with top tankless water heater installers in San Mateo, CA

"I called and they were here working 48 hours to install and haul away a tankless water heater. They did finishing work and completed it to my high standards. They communicated very well as I was uneducated in this area. I highly recommend them."

"Steven Tinetti at Maverick Water Heaters & Plumbing is an expert in tankless water heaters. He looked at my particular situation with my water heater to find the best solution and gave me estimates for multiple solutions with a pro and con list for each. I felt I could really trust what he was telling me."

"My tankless water heater went out on a Friday night, and the Water Heater Boys were able to replace it on Saturday the next day! Excellent customer service and professionalism. Will definitely call if in this situation again, and will tell my friends!"

"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."

"Since my current water heater was 17 years old I decided to replace it before it gave out on me. I emailed Better Water Heaters in the evening with the details and got a phone call from Frans who scheduled Daniel to come and give me a free estimate the next afternoon. In the meantime I got another quote from another installer after texting photos of the current installation. Daniel’s estimate was similar for a standard water heater replacement but although I had not considered a tankless install I asked for a quote on that as well after discussing pros and cons with Daniel. Daniel then waited while I discussed this with my wife and since he could do the install the next day I decided on the tankless install and Daniel arrived the next morning and completed the install in three hours. I am very happy with the quickness and quality of the work as well as the quality of the Rinnai water heater that was installed."

"Steve Tinetti, owner of Maverick Water Heaters, is terrific! During the big storm the first week of January this year, our power went out and our tank water heater blew. Painful. We had been thinking about the tankless option for some time so we called Steve about 5:00pm and explained the situation. We talked it through and he came to our home the following morning at 9:00am to assess the situation. Despite being a more complicated installation than most, he said he could do it right away (I think he actually took personal pride in taking on the challenge). Steve bought the tankless water heater we wanted (higher end) and got to work. By 6:00pm that day we had instant hot water (within 24 hours of our initial call). He came back the next morning for a couple hours to finish up the complete installation and we were good to go. I can't say enough about Steve and his high quality, efficient, and professional service. He is a long time Coastside local, independent business owner/operator, and one man show. He explained everything clearly and in detail. He did a superb job and I know this wasn't easy. The heater is in the garage up high on a loft and on the side opposite where the air vent needed to be routed. Yet he made it work and did so very quickly. And, he's just a good guy. A couple months later, we are thrilled with our tankless water heater. We are very glad we made the switch and feel very fortunate that we found Steve. I highly recommend him without reservation ."

"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."

"This plumber arrived very soon to check the issue and he repaired our water heater at his first visit. Thanks for his good service. "

"Albert Nahman Plumbing was helpful and extremely professional. The work done by Nicholas was resourceful (involving hooking up a new heater with different requirements into a gas supply and vent system installed thirty years earlier) and carefully executed. He's a knowledgeable, courteous, and highly skilled professional."

"My water heater was leaking and I needed it fixed asap because we had no hot water and I have small kids at home. Robert came, he saw the problem and fixed it fast and efficiently. He was professional and polite and the price was right. I will definitely call him again in the future. And have recommended him to family and friends. Thank you Drain Right Plumbing!!"
