John installed two Rheem tankless water heaters for me. He was on time, professional and very knowledgeable. I would definitely use again. On a side note he gave me a great price.

Very rare to find a person like Chris Castro. I was amazed the response he gave me to help restart my gas line on my tankless water heater early in the morning. He immediately gave me a code to restart without a service call. Matter of seconds it restarts. Wow. No financial gain. Would no doubt only call John Castro Plumbing for my plumbing needs.

My tankless water heater broke down during some stormy weather and one of the technicians (Chris C.) had reached out to help me troubleshoot. It turned out that there was a power/electricity issue, which helped me save time and money in fixing this issue. They responded very quickly and helped guide me through the troubleshooting process free of charge. It was much appreciated especially during the winter where every day without hot water counts!

I called Chris because our very old water heater had kicked the bucket. He helped me find the kind I needed, even though he was booked for the day and couldn't do the actual job. It's rare to find someone helpful and kind unless they are getting paid. I will 100% call him again when I have another plumbing issue.

Fantastic service. Was happy to diagnose issue over text free of charge to try and fix it over the phone before he even got here! Very friendly guy and happy to explain everything he's doing and why he stands behind the brands he chooses to install. You won't find anyone more knowledgeable about tankless water heaters, and I doubt you'd find a better price!

Chris at John Castro plumbing has been the best plumber I have ever used. He was able to help me troubleshoot my hot water heater problems and help me apply for the manufactures warranty.

Five star service, thanks Chris.

Chris Castro thank you so very much for answering my call immediately and carefully listening to the problem I was having with my water heater and trouble shooting with me over the phone. I did the things you asked me to and the problem was resolved! Best service I've received and you have my trust! Thank you so very much!

Chris had been communicating with me for the past year about getting a tankless water heater. We moved out of the country for 6 months, so it had to be delayed, but when we got back, I was ready to get this baby going.
Chris was responsive as usual, gave me updated quotes, and eventually we scheduled a date and he came and installed.
The outdoor tankless opened up so much space in our laundry room that formerly was cramped with a huge tank. He rolled it out front- picked up in less then 30 minutes.
He expertly worked on the piping and install, and let me pick his brain while he was at it (I'm a DIY queen and very curious how all the things work).
I have had it with tradespeople overcharging and doing shoddy work. Chris was NOT that tradesperson. He did great work, and his rate was below what I expected. He informed me what to do to get the rebate, and we received our check in a few weeks.
All in all, great experience with Chris and very glad we went with him. Now when do you get to say that about a tradesperson?
Thanks!

We needed to replace the dying tank water heater in a hurry. I had done a weeks worth of internet research on all the tankless options and was feeling overwhelmed. I had a general contractor who was happy to put in a Home Depot basic unit for cheap. But the more research I did, the less answers he had in response to my questions. My regular plumber, on the other hand, tried to quote me 8k. Totally insane for a small 2 bedroom one bath house.

Finally had Chris come over to give me a quote. He's the one you want. He's knowledgable and takes the time to explain everything. He knows all the brands and stands by the ones he uses. Then he also made it super easy by doing the paperwork for me to submit to get the rebate that essentially pays for the unit. So you're basically paying him for expert service. You can tell he takes real pride in his work. He was here at 9am, and done by 1pm. Hot water ready to go on demand. No more giant tank heater in my kitchen. Save some time and worry. Hire Chris if you're ready to go tankless.

Chris Castro, John's son, is terrific! After my water heater broke, Chris came to my house the following day and provided me with a loaner at no charge. Then he was able to get a discount on my new water heater thanks to his great connections and knowledge. He installed a beautiful new water heater perfectly and also included extras like a hard water softener. I highly recommend Chris and will be using him again for future plumbing issues.
