About Us 

History: David Riley: “In the mid seventies I was working in quality building circles and people would regularly ask me to look at renovations they weren’t happy with, buildings they had bought that were full of surprises and problems to which they were getting conflicting responses. While trying to help various people I decided to formalize my commitment to working in these situations and incorporated IHD."
