Get matched with top tankless water heater installers in Hayward, CA

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

"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!"

"Tony and his crew were skilled, professional and did a wonderful job. When I listed the job on Angi, Tony responded within 20 minutes. He asked about the job, asked for some pictures and I had a solid quote within an hour. Our installation had some challenges and, instead of making these issues more complicated and jacking up the price like other contractors did, he quickly came up with sensible solutions at a fair price. The job was done in one day and our new tankless water heater is superb! I highly recommend Tony and Tankless Plumbing Solutions."

"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."

"The entire project from start to finish was fantastic. Within minutes of requesting a quote I received a text with a time they could be at the house. Rodney called to ask some questions, gave me an estimated price and time. Rodney was great to talk to and was very knowledgeable and helpful. Rolando arrived a little early which was great. He figured out what needed to be done and gave me an estimate which was within the range mentioned and started working. It took an hour to complete. Rolando went over what was done and why. I was extremely impressed with Rolando, he was courteous, informative and did a great job installing the water heater and bringing everything up to code. I wouldn’t hesitate to call Better Water Heaters again."

"Beni did a great job. Installed water heater in under 2 hours. Handled install with old galvanized piping. Had the lowest estimate and charge was the estimate. Very satisfied."

"They installed a Moen water shut off and a gas earthquake shut off. They were on time, efficient and professional."

"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."

"Robert and his team saved us from an emergency with groundwater flooding under our house. I called them at 8pm and they were out within a couple of hours that night and worked until midnight to install a sump pump. They did excellent work and were very communicative about the work they were doing. I highly recommend Facilities Plumbing."

"I posted a review earlier and I need to revise it . The work done was for a standard water heater , not a tankless water heater"
