Get matched with top water heater repair or service pros in Alameda, 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!"

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"Excellent customer service. I was impressed by their professionalism and attention to detail. They understood my needs and the urgency of my project -I placed a call to get an estimate, 5 hours later I had a brand new water heater installed."

"Excellent service! Pablo called immediately after I had submitted my HA inquiry, to see how he could assist with my project. He was able to come to my house same day; and even showed up to the appointment earlier than expected. He did the work efficiently and well, and was very courteous. Great service and for a reasonable price. Will definitely call Cost U Less Plumbing & Drain in the future when I need a professional plumber. Thanks Pablo!"

"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."

"I highly recommend the company (Costello's Plumbing) as well as the employee who helped us (Miguel). My wife spoke with Mr. Costello this morning, and booked an appointment for Miguel (one of his workers) to come over and look at the situation / prepare an estimate. He did so (arriving iwihin the appointment window), gave us a good quote, and indicated the two parts that needed replacement (the garbage disposal unit and the cold water dual shut-off valve. He indicated that we could purchase those parts through the company, or if I had the parts onhand, he could just install them (saving money). Fortunately, The Home Depot nearby was open, and I was able to get the two pieces fairly quickly. Miguel then: * installed the garbage disposal (and took care of getting rid of the old one), * connected the replacement shut-off valve, * replaced the faucet itself, and made sure that none of it leaked. A job well done!"

"Showed up on time and quickly repaired issue"

"Mr. Leo & Javier did a " Wonderful" Job on the Repair. Without them, I wouldn't know where to Began. I just Love the Thought and the Feeling of " Warm Water Again." I'm Very Appreciative to Leo & Javier. I will Allways Call Recommend them to my Friends& Neighbors."

"had them replace my water heater with a tankless. Price was fair . Even made sure everything was running great the next day"

"Called Trio Heating on a late Friday afternoon and they sent out two technicians (Jose & Dallin) the next morning to fix a gas heater that would not turn on. Their communication from beginning to end was great. They sent me a text 45 minutes before their arrival time and I was able to track their ETA which was extremely helpful. They explained to me what the issue was. I was able to run out and buy a new thermostat for them to install. They did a great job, cleaned everything up and put everything back together. They also typed up everything they worked on and took multiple detailed photos of the unit and emailed 10 minutes after they left. I think what they charged was extremely reasonable for the quality of work. I really appreciated not being charged a higher fee for coming out on a weekend. Will definitely use them again for my HVAC needs!"
