Chris came by and assessed our water heater at 430pm. He tried trouble shooting, but recommended to replace the unit due to the age. He was able to come back with all parts and new unit as promised the next morning. He didn't waste anytime andand had the new unit running within a couple hours. Chris is very knowledgeable and personable, I would recommend. He has attention to detail and cares about the end solution and product.

I never write reviews, but Chris was beyond amazing. He guided me over the phone for a few days when my tankless water heater was getting near end of life. Would do business again in a heart beat and highly recommend.

Chris from John Castro Plumbing is exemplary as a plumber and as an ethical businessperson. I called John Castro Plumbing on Sunday of Memorial Day Weekend thinking that we needed to replace our 15-year-old tankless water heater that had been malfunctioning. Chris picked up right away. Rather than try to sell me on a new tankless water heater, he spent an hour on the phone with me walking me through steps to try to get our existing system back up and running. Sure enough with his patient and complimentary assistance over the phone, our system was back online. I wholeheartedly recommend Chris and John Castro Plumbing.

I was in the final stages of a home remodel and my new tankless system put in by another plumber wasn't working as expected. Before my final inspection was scheduled, I wanted a second opinion to make sure everything plumbing related was done properly and called John Castro Plumbing.

I spoke to Chris on the phone and he was in the area and stopped by on a Sunday evening to take a look. Who does that these days!! Chris looked at my plumbing, listed all the issues that needed to be corrected, and helped properly program my tankless system. I was so grateful to Chris. He gave me the reassurance that I needed. Thanks for everything, Chris!! I will definitely be using John Castro Plumbing for my plumbing needs in the future.

Chris Castro installed a tankless water heater at our house and did a terrific job. The price was more than fair, especially in light of the meticulous work he did. His knowledge of various tankless heaters and their characteristics was equally impressive.

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!
