"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."

"Jaleen from Albert Nahmans is top notch , diagnosed the issue with an old furnace , fixed it and made recommendations for repairs and or replacement . A huge thank you!!"

"Good quick service. They did the install in one day notice and it came out to just under $4k for a tankless install. Professional clean work."

"Dan and the team did a great job on our Rheem heat pump water heater installation. They were quick, thorough, clean and the new water heater works great! I?d definitely use Cali again!"

"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 installers were timely & polite"

"Robert the installer, was very personable and thorough with the installation and explanation of how the unit works. I appreciate him and his work. Thank you Robert."

"We found these folks to be excellent. We had an emergency and they had someone here in a couple of hours and did a nice job on the repair--really rescued us from a pretty desperate situation. We then hired them for a new sink install. They were prompt, courteous and understood our needs. Jay provided responses and advice immediately by text. He and his crew are very knowledgeable and competent--clearly very experienced. The prices seemed high to me at first. Jay reduced some costs a bit and I ended up feeling we got full value for the work performed."

"Really great customer service before, during and after the service call. Instilled confidence. Provided simple solution to dramatically reduce the time it took to get hot water to the primary bathroom. Planning to work with them to install new high-efficiency water heater system in the near future. Compared to other plumbers I've worked with in the past, Big Blue is HIGHLY RECOMMENDED."

"Our service technician was very well versed in plumbing issues. We had a couple of quirky issues with our new home-- one was murky or cloudy water at various faucets throughout the house. Another was warm water coming from the cold faucet late in the afternoon at the main kitchen sink. We suspected air pockets in the pipes was causing the murkiness in the water and that the pipes were getting warm from the sun in the kitchen. This was confirmed, but we went through a number of tests to rule out other possibilities. Our technician thoroughly analyzed our entire house, the products we installed, and then went away and did some research on his own on our water heater and other products or solutions that we could consider. We were very pleased with his knowledge and attention. The charge was more than fair for the amount of work and time he put into researching our problems. We will definitely use Oak Plumbing in the going foward."
