About the Home Inspector
Dan Joandrea

- I have been working in the home remodeling / construction industry for over 11 years. I have decided to open a home inspection company to help real estate home buyers to make an informed decision before making their biggest investment of their life. The home inspection is a very important step when purchasing a home.
