"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.

We recommend him without hesitation to anyone needing plumbing services."

An independently operated plumbing company dedicated to providing expert service, lasting solutions, and exceptional care

"We did not have a go-to plumber, nor did our neighbors, so we asked Angi. They recommended Steven Bailey, and it was the right choice. The job was a simple replacement of a traditional bathroom sink drain plug with a pop-up that will catch hair and, we hope, prevent future clogs. Steven was responsive, knowledgeable, and friendly, and he explained the options clearly and simply. He is an honest and skilled tradesman, and charged the minimum for the job, which was less than other quotes. Now we have a go-to plumber, and you can too!"

"Isaac and team were incredible in getting a bunch of updating old and out-of-code plumbing work done on our tricky 100-year-old house. They took time to really dig in and assess the right game plan to make sure not only that all the plumbing and vents were done properly, but that they looked great given some would still be exposed / visible under our porch. The team was communicative and courteous. Our new plumbing is working like a charm. The tankless heater and smart shutoff are cranking. And everything passed on first inspection. The inspector even commented how clean and detailed it all looked. Would recommend SplashFix for any project, big or small."
