"Water Heater Masters came the same day that I first contacted them and replaced my heater that day as well."

"Carl and David were phenomenal. They were competitive with pricing, installed and hauled away my old water heater, and were extremely friendly. 10/10 would recommend"

"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."

"Problem is fixed. Also I learned how my house's plumbing is configured and how to help maintain clean, free-running pipes with this configuration."

"Ms.Dee is amazing and Brandon is a great plumber! They were able to take care of my leaking water heater same day! Saved my items in the garage and a headache! On a Friday!!!!! I will recommend them to everyone"

"Excellent from start to finish. Arrived on time, replaced our old water heater with a new one, left everything very clean and, from what I can tell, provided excellent workmanship at a very reasonable price."

"The day the service was scheduled did not go well. We were scheduled between 8 and 12, but they called in the morning to move it back to 10 to 2. I called them after 2 because we had not heard anything. The technician finally came around 3:45. I think it is very poor customer service to expect someone to wait all day for a service call. Once the technician arrived the service was done very professionally. He did find that they should have enlarged our vent with the install two years ago, and they will have to come back and do that. It makes me think they did not have proper attention to detail during the install. There also was an up-sale so that a $79 service call ended up costing us over $450."

"Tom came when he said he would and got the job done quickly, too. My shower works very well now. Thank you, Tom!"

"Jared showed up and wasted no time in doing two things at once (draining the hot water heater and repairing a small fireplace gas leak). He educated me a little on what he was doing which is always helpful. He was also careful to keep his booties on, so as not to ruin the shiny wood floors. Highly recommend based on this experience."

"Very prompt in responding to my initial inquiry (Sunday no less) and salesman was terrific. Installation took 2 full days by a team that seemed professional and knowledgeable. I was shocked however by the fact that 2 men on the installation team smoked all day long. My property is rural with no fire hydrants - the prospect of fire is terrifying to me. At the end of the 2 days the system was installed but it took an additional technician coming out after the crew had left to get the system functional."
