"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."

"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!"

"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."

"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."
