Best water heater pros near 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!"

"I got home from work and discovered that my water heater had a major leak that required shutting off the water to the house. Carl at Cali Water Heater responded immediately and less than 24 hours later I had a new water heater installed, water restored, and all at a fair price. Highly recommend!"

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

"Sal contacted me promptly and set up an appointment the same day. His estimate was nearly $1500 less than the estimate I got from Greiner Heating & Air. Showed up the following day on time, was very personable and well organized. I used to work in the building trade and I can attest that he did an absolutely professional job of replacing our water heater."

"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"

"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."

"Marcell and True Blue Plumbing were a pleasure to work with. He was friendly and took pride in his work and client satisfaction. Marcell installed a gas line for me in Napa within the same week of providing the estimate, and he even helped me flush out my water heater free of charge. I will definitely use him for any future plumbing needs. My profession is a property manager and itâ s hard to find quality vendors like True Blueâ ¦Thanks again."

"Oak called 2nd but came next day/ UN-prepared to do either repair or water test (requested on phone) or even replace with ready new ADA toilet that the lying receptionist booker said they have “some in stock and if not he will show a catalog of choices”. Guy came punctually with Nzo tools or appliances Or knowledge of what I asked for as an “URGENT repair/replace”. See ABC review same call. Not quite as bad as them doing same since we also still have broken HVAC too, both said they would fix ( I bought gasket already, they could have put in) or replace if they brought new toilet. Problem is not in water pipes except they need testing for lead - both said they would do this too - when I asked oak re taking a sample, how long sitting in pipes? He wiped off his soda water bottle and asked “which pipes?” !!"

"Everything went ok as far as I could tell, but yesterday a plumber told me the gas line was not large enough and that is why the water heater is not working properly."

"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."
