Get matched with top tankless water heater repair pros in Corte Madera, CA

"Very professional -went great ! Did a retro install of tankless water heater and had us up and running in 4 hours."

"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."

"Excellent from start to finish. Arrived on time, replaced our old water heater with a new one, left everything very clean and, from what I can tell, provided excellent workmanship at a very reasonable price."

"He is really great, always responsive really happy with their work. great guy."

"These guys are the best. Did a partial home repipe of both the water and drain pipes. Other plumbers tried to upsell us by replacing newer pipes and the water heater. Ray and Alex just did the repiping that was necessary. Excellent communication, friendly and on time. Even worked in tough, rainy conditions. Ray owns his own business and takes pride in his work. Recommended him to all my neighbors."

"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 quote/price for the repairs was very reasonable, as will as quick service. One of the things that I really appreciate was that both the technician that can to give the quote, and the technician that can to do the repairs both respected COVID Protocol including fresh booties for their shoes. Oak Plumbing will be my go-to plumbers for all my plumbing needs."

"The installers were very sweet and professional. But I donâ t think I was made completely aware of how the exterior installation would look. The last 4 or 5 feet of the white pipeline are not covered and it looks unfinished and messy."

"Steve installed an earthquake gas shutoff valve. He carefully and thoughtfully considered the best way to make it fit in the limited space, and ultimately came up with a super-efficient solution that required a minimum of new piping. He explained and demonstrated how it worked, and how to turn it on and off. As he turned on the pilot light for the water heater after installation, he explained how to do it if I ever needed to do it myself. Quick to respond to my initial inquiry and further questions. Excellent service -- highly recommended!"
