Get matched with top tankless water heater repair pros in Castro Valley, CA

"I have what turned out to be a 30 year old water heater replaced by this great company and they did it the same day of the quote. The installer had the water heater I wanted on the truck and did an excellent job of putting in the new unit, cleaning up and even replacing copper flex tubing and installing a new overflow pipe out of copper as well, no additional cost. This company specializes in water heaters and couldn't do any additional work on supply lines and they clearly state that on their website. I didn't need that type of additional work."

"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"Pedro installed a tankless water heater for me. Very professional and reasonable. Would hire him again."

"They installed a Moen water shut off and a gas earthquake shut off. They were on time, efficient and professional."

"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."

"I posted a review earlier and I need to revise it . The work done was for a standard water heater , not a tankless water heater"

"They did a number of things. Braced and restrapped water heater and ran copper line for pressure relief to outside. Unclogged master toilet and reseated. Bolted down second toilet. Reconnected clothes dryer vent. Repaired air gap/garbage disposal and drain line under kitchen sink, crawled under house and remove galvanized pipe straps and replaced with nylon pipe clamps. I was a contractor and used to do this work, o an very critical. They did an outstanding job. Went the extra mile several times. I was expecting a bill for a higher amount but they stuck with their estimate. I recommend them highly and would use them again!!"

"Robert was an amazing plumber to work with. Extremely professional, knowledgeable, responsive and honest. All traits that are hard to come by in this profession. Ever since I found his business, Iâ ve never even bothered to look elsewhere. He never tries to upsell you, gives you options and always cleans up meticulously. Iâ ve recommended him to all my friends and family and they were all happy with his services. So far heâ s fixed my clogged sink, installed and repaired my garbage disposal, came immediately when my storm drain busted, and gave me quotes and advice on a tankless water heater. Hopefully I wonâ t need his services any time soon though!"

"Really great customer service before, during and after the service call. Instilled confidence. Provided simple solution to dramatically reduce the time it took to get hot water to the primary bathroom. Planning to work with them to install new high-efficiency water heater system in the near future. Compared to other plumbers I've worked with in the past, Big Blue is HIGHLY RECOMMENDED."

" Marvin is a very skillful and professional man. He is a very detailed and neat person and not rushing to finish the jobs. When he completed the repaired job, he repeatedly ask you to review and check over what he’ s done until I satisfied. "
