Get matched with top tankless water heater installers in Walnut Creek, 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."

"This was the first time I had used Angie's list to find a contractor. I was nervous not knowing whether I would get good service. I cannot say enough about Water Heater Masters. They were so professional and did an excellent job. They showed up on time, explained my options but didn't try to influence my decision. The workman was very neat, taking care to clean up some water spillage after draining my old water tank. I cannot say enough about how impressed I was at the service I got. And the price was very reasonable. A local contractor I called had quoted me twice the price for a new water heater installation. I have no hesitation in recommending this company."

"Tyrone was amazing. Tespo fed right away to our posting of the job and showed up on a Sunday to take out the old gas tank and replace with the Hybrid Rheem. Spotless installation and live the heater!!!! Highly recommend this company and what a great group to work with"

"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."

"Cali Water Heater Solutions gave a reasonable quote for my new tankless water heater, then did the job quickly and thoroughly. I highly recommend using their services. The team is professional, responsive, and deliver on quality service."

"Dan responded quickly and was able to take care of the problem . . . but then he discovered a hidden problem to which he moved quickly and ended up replacing the 20-year-old tankless water heater with a new unit. Absolutely outstanding service."

"Great service. The technician came early and replaced the water heater in a few hours. Was very professional and knowledgeable"

"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."

"Ms.Dee is amazing and Brandon is a great plumber! They were able to take care of my leaking water heater same day! Saved my items in the garage and a headache! On a Friday!!!!! I will recommend them to everyone"
