Get matched with top tankless water heater repair 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!"

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

"JPC team did an excellent, professional job on our storm water sump pumps related project. (Two sump pumps were working; they did not need repairs.) 1) Cut and replaced two broken pipes; installed new valves 2) New float sensors installed and set to auto-start the sump pumps 3) long outflow pine, connecting to city's water drainage system, was cleaned using long snake and high pressure water pump combination. 4) successful final test with water filled in water chamber and sump pumps working 5) JPC gave warranty for work done and signed up for once-a-year annual maintenance visit in October."

"Showed up on time and quickly repaired issue"

"Mr.Rooter was not available for a week. Staff was please. I just could not wait to fix a non functioning kitchen faucet"

"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."
