Get matched with top tankless water heater installers in Vacaville, CA

"Water Heater Masters were top-notch! I called on a Saturday afternoon - they were available 9am Sunday morning to come and inspect and quote. They only had one guy working that day, but scheduled me for Monday morning between 8 and 9. At 8:15am I got a call with an ETA of 8:45, which was a really nice touch! Despite telling me it would take an entire day to install, they were done by 1pm. They also found some creative ways to do the install to avoid drilling through my stucco (for the exhaust vent and for the condensate run-off). Very professional and clean-looking install. These guys may not always be the cheapest around, and they recommended a top-of-the-line heater (which is what I really wanted anyway), but I'd much rather pay a little extra for that level of service and support. Thank you!"

"Great education from the tech. Professional and prompt. Unfortunately the water heater still isn’t working as well as it should"

"Very friendly and responsive. Quick work done in a professional manner. The Water Heater Guyz were the only pros who included permitting as part of their service, which was the initial selling point for me."

"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."

"They did a great job replacing my water heater."

"We chose BeastBay Plumbing for a complete home repipe after meeting with several companies. Ron Buris and Jovon were professional and promised great service, which is why we hired them. I requested the work be permitted. The crew worked hard, but cleanup could have been better. Unfortunately, the day after the job was completed, a newly installed pipe behind our chimney leaked, soaking our brick fireplace. They repaired it, but it leaked again a couple of days later, causing more water damage. We had to shut off our water and went without water until Monday because no technician was available Sunday. I was told someone would bring fans to dry the area, but no one came, so I rented them myself. The city later failed the inspection, requiring additional corrections. We paid quite a bit for this project. After final payment, communication became very poor. I expected better follow-up and accountability for a job of this size."

"Winters plumbing service came out and installed a water heater for us. It was a difficult job and they executed it to perfection. The technician was polite and courteous, and also cleaned up after the job."

"Jason was very polite and the completed job was great. They disposed of the old tank water heater cleaned up the area and the install was completed in about 4 hrs. Very satisfied with the unit and the installation."

"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."
