"I came home on New Year's Day to discover a puddle under my water heater! Well, it wasn't a total shock; the thing was 25 years old. I called Water Heater Masters that night; they were closed, but I left a message requesting an estimate and continued making calls. The next day, Matt called me back at 7am (I might not have been entirely awake...) and quoted me a price of $1050 for a 40 gallon Bradford White professional-grade heater. That was $300 cheaper than the next closest estimate by a licensed plumber, so I jumped on it. Will was here by 8am and done by 9:20. He was punctual, professional and friendly, and the work looks great so far!

"I feel that I was very lucky have chosen Corsa Plumbing to do diagnose and replace 2 sewers for me. One in Lafayette and one in Pleasant Hill. Ray, was easy to work with and he did a great job of advising me on the existing problems and explaining what they would do to fix them. The camera inspection of the sewer line and the estimate were free. I was present when he did them. Both of the bids were fair, but do not include the cost of County permits. I will highly recommend you get a bid from Corsa Plumbing. You won’t regret it. You can hardly tell that the sewer was replaced Steve Walsh, retired Realtor and property manager for residential homes."

"BeastBay plumbing came the next day and did a good job!"

"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."

"You would be very glad you called them instead of these other major plumbing companies. They took so much worrying off me and my family mind. They did not try to take advantage of the situations due to its emergency status like some company does. They come highly recommended by us."
