Hello my name is Jason William Hornung. Buying a home is a big investment. I want to help you make a well informed decision. I have been in the residential construction field for 17 years, and have an intimate knowledge of the homes in our area having done so much work in them myself. I stay continuously trained studying current information to give the best reports out there. I've seen many things that other inspectors have missed both as a home inspector and a contractor. My inspections meet or exceed the ASHI standards of practice. WWW.Homeinspector.org/standards WWW.JWHInspections.com

Lance was very helpful in explaining the process when he booked my appointment and the two techs who installed the radon remediation system were professional and courteous.
