 Trustindex verifies that the original source of the review is Google. Jacob Estrada installed our tankless water heater and was a complete professional from start to finish. Courteous, punctual, and genuinely knowledgeable — he explained every step, answered all of our questions patiently, and walked us through the new system before he left. The work is neat and the site was left spotless. If you can request a technician, ask for Jacob by name.

 Trustindex verifies that the original source of the review is Google. The technician Miguel was up front professional and worked very well by himself. He went through every step of the process and how long it will take. He completed on time and no mess. Recommend Castleworks if you need a water heater replaced.
