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

"I have what turned out to be a 30 year old water heater replaced by this great company and they did it the same day of the quote. The installer had the water heater I wanted on the truck and did an excellent job of putting in the new unit, cleaning up and even replacing copper flex tubing and installing a new overflow pipe out of copper as well, no additional cost. This company specializes in water heaters and couldn't do any additional work on supply lines and they clearly state that on their website. I didn't need that type of additional work."

"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."

"It went very well and all the issues were resolved quickly. Adan was very professional and confident service person. We highly recommended Payless water heater and plumbing."

"Our water heater started leaking and needed to be replaced. Called in the morning and had someone out in the afternoon. This was actually our second quote. The first guy only gave the heater a cursory look before quoting a price. The Better Water Heaters technician actually examined the heater, plumbing and electrical connections before discussing options. We discussed replacing the original and switching to a tankless system. After we did some research and asked some friends who had a tankless system, we decided to go with the tankless. We scheduled an appointment for the next day and had it installed. Very smooth, very professional."

"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."

"Excellent Arrived on time. And excellent installation."

"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."

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."
