"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."

"Was selling my apartment and wanted to service heater prior to listing. Moore provided great technicians who tried everything they could to reset and fix some mechanical issues. Provided lots of info and updates while they worked, showed me everything they were doing, where problems were, etc. In the end, the heater was too far gone and a whole replacement was recommended. Moore was able to schedule the replacement within a week. Whole project was completed in 4.5 hours and came in under their initial estimate. 10/10 would recommend them to all friends and family."

"I would highly recommend Ray’s Rescue Plumbing. He was very clean, prompt, courteous and knowledgeable. We had several issues ranging from leaks, repairs and installing a tankless water heater. Ray’s prices were competitive and he actually saved us a few thousand dollars from a previous bid from a ‘not so honest’ plumber."
