Get matched with top tankless water heater repair pros in Fairfield, 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!"

"Jamie is first class. Had my tankless water heater running and provided good advice."

"True Blue Plumbing installed a tankless water heater, including complicated piping for both ventilation and overflow. I found Marcell and his son to be trustworthy, kind and fair, and to do what they said they would do. All of that without ever being told they would get ice cream bars upon their job completion!"

"August 25, 2026 Rated 5/5, I am writing to express my appreciation for the excellent customer service provided by Horacio Parker, a plumber with Beutler Air Conditioning and Plumbing. On August 25, 2026, water was leaking from my water heater onto the garage floor. Mr. Parker responded promptly, listened attentively, and showed patience, empathy, and understanding of my concerns. He was courteous, polite, friendly, and maintained a professional, positive attitude throughout the service call. Mr. Parker shut off the power and water, drained the old 75-gallon Bradford White water heater, and installed a new 75-gallon Bradford White Energy Saver water heater. He communicated clearly and showed me how to shut off the water to the house and turn off the water heater to help prevent future flooding. Mr. Parker is an asset to Beutler Air Conditioning and Plumbing, and any company he provides service to Lovevasia Bey"

"The plumber showed up within an hour of my request. He thoroughly inspected my tankless water heater and discovered the issue quickly. Problem solved. I would definitely hire the personable and efficient plumber again."

"The plumber came almost at the end of the appointed time. When he arrived, he was fairly arrogant, and refused to negotiate despite coming from Angie's list. Lastly, he repaired the leaky line in about an hour, charging $530, and also did not provide the water plastic box for water line. We had to purchase one from another store. When I paid for the invoice, they didn't tell me that they are charging additional 3% with credit card. All in all, they did the work, but at a high price, and so so customer service."

"They fixed a major water leak and installed a new water heater all in one day. They were prompt and did a neat install. I can recommend them."

"Of the five businesses I contacted for estimates, I thought the Bonney installer gave me the most honest up-front estimate (although it was also the highest estimate). Some of the businesses would only give me over-the-phone low-ball estimates that were obviously just for the water heater itself, neglecting to mention the extra components that would be needed such as valves, strappings, expansion tank, and an electrical disconnect box, all required for the City permit. And only a couple of businesses, even one who came to the house, bothered to mention the required City permit. The Bonney installer showed up on time with all the required equipment. He removed the old tank and components, prepped the area for the new components, and completed the installation in about five hours. He also cleaned the area thoroughly when he was finished. Overall, I'm very satisfied with the results. It passed the City inspection. And I also think I got a better quality water heater brand which isn't available online or at discount big-box stores."

"explained the work before hand. Experienced technician who was quite knowledgable and finished the work efficiently and cleaned up when finished. Explained ways to keep the water heater functioning well."

"They quickly provided one day service call, and fit our repair into their busy schedule."
