Get matched with top tankless water heater installers 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."

"The Water Heater Boys are true professionals! They were able to help me the same day as advertised! I highly recommend them!"

"Tony and his crew were skilled, professional and did a wonderful job. When I listed the job on Angi, Tony responded within 20 minutes. He asked about the job, asked for some pictures and I had a solid quote within an hour. Our installation had some challenges and, instead of making these issues more complicated and jacking up the price like other contractors did, he quickly came up with sensible solutions at a fair price. The job was done in one day and our new tankless water heater is superb! I highly recommend Tony and Tankless Plumbing Solutions."

"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."

"Beni did a great job. Installed water heater in under 2 hours. Handled install with old galvanized piping. Had the lowest estimate and charge was the estimate. Very satisfied."

"I don't know enough to compare (dollarwise) the tankless water heater I purchased to others in the market. I can say it's an impressive piece of equipment and is providing my desired level of service. I now have hot water throughout my home in seconds! AND, Dave impressed me immediately as a sound, honest, energetic business man and technician. In no time he and Carl were at my house doing the work I desperately needed. It was dark when they finished but they lived up to their word in fixing my hot water problem "today"!"

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

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

"The cost to replace three natural gas wall heater was slightly less than Gree mini-splits heater cooler. The installers were courteous and professional. Delayed several days as the equipment haven’t arrived yet. Job cost as agreed, but took half day longer due to the complexity of installation. Results are excellent. The mini-split units works as specified. Will use Albert Nahman heating plumbing again in the future."

"I did a bit of research even though we had been without hot water for about a week. Mainly because we had roofers working and no roof where the water heater would be going in the garage. I received a call from Robert before we were ready for the project to begin and wrote down his info including the quote. I wanted a long warranty and not many companies were offering the 12 yr warranty. That was a plus, and when I finally made the decision to go with Facilities Plumbing and Drain I called Robert and he said Frankie could come right away...within the hour...it was about 550PM!! He indeed showed up and went straight to work with a smile. What a great attitude he has, especially considering he had been working since 7am. Hot water heater installed and he cleaned up everything too. Very professional, very nice and efficient."
