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

"Water Heater Masters were top-notch! I called on a Saturday afternoon - they were available 9am Sunday morning to come and inspect and quote. They only had one guy working that day, but scheduled me for Monday morning between 8 and 9. At 8:15am I got a call with an ETA of 8:45, which was a really nice touch! Despite telling me it would take an entire day to install, they were done by 1pm. They also found some creative ways to do the install to avoid drilling through my stucco (for the exhaust vent and for the condensate run-off). Very professional and clean-looking install. These guys may not always be the cheapest around, and they recommended a top-of-the-line heater (which is what I really wanted anyway), but I'd much rather pay a little extra for that level of service and support. Thank you!"

"Alberto did an incredible job installing our Navien NPE-180A2 tankless water heater. He made the pricing fair and transparent which really helped. It’s so hard to navigate all the outrageous and confusing pricing options offered by nearly all the other plumbing companies, so I’m really grateful that he came in with a fair price from the start. Also, the install was done with such care using commercial quality materials that I know will last for years to come. Highly recommend Premier Plumbing! Thank you Alberto!"

"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."

"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."

"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."

"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."

"Confirmed the status of the heater and gave me peace of mind with the knowledge."

"Mike was professional and fixed both showers, noting that the shower pipe valve for our new shower/tub had been installed incorrectly. He was very pleasant and professional. In fact, we had a toilet overflow and ceiling water leak hours after he left -- he was responsive over the phone and we were able to diagnose the problem. He even texted me afterwards to see if there was still a problem (there wasn't). Would use Mike again in a heartbeat. He is our plumber of choice moving forward."
