Miguel was the technician that arrived within a few hours of my call to check on my water heater. He quickly assessed the situation and provided me options. I decided to go with a new water heater and he had it installed in just a couple hours. I was able to give my toddler a warm bath before bedtime!

On Sunday November 8 our water heater broke down and also had a bursted pipe. We called CastleWorks Water Heaters and they made sure we turned everything off properly and set up the water drain system correctly. Within 90 minutes a technician named Erik Vargas arrived, and let me tell You -- this Guy was fantastic! Erik went through all of our options and explained everything perfectly and then went to work installing our new Water Heater. After the technician Erik left our garage looking better than it ever has. CastleWorks gets a rating of💯👍🧑‍🔧 from us. W.P. Biagi
