 Trustindex verifies that the original source of the review is Google. Elston Walker was the water heater technician that Castle Works dispatched after regular hours when our 25 year old water heater went out with a splash😩Elston has a brand new up to date technology water heater installed within 2 hours. We caught our flight and now I am posting this from Lisbon Portugal and our daughter has all the hot water she needs!🤣
