"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.

"David and Eli at First Class were knowledgeable and personable. David responded in five minutes on a Sunday and came out the next morning. They would have charged $1300 less than the other bid for a 50 gallon heater but we chose a Navien point of source to save money on PGE gas bills. That cost $3900 July 2025-beware tariff price increases - which was half and less than competitors. "

"Spent too much time discussing a replacement faucet. Did schedule very quickly which was appreciated, did do the work requested quickly after “discussion “ stopped. I do feel that the “come on” $49 work estimate fee gets you involved with them when you have no idea that the cost would be so much! This I find is the norm with plumbers on Angi. Total cost for a simple procedure( yes I could not do myself) was at least 50% more than I thought."
