A little background about the company and myself, my name is Zac Knoblauch. I am a Certified Inspector through AHIT (American Home Inspectors Training Institute), licensed home inspector in the state of Illinois (license #450.011629) an ASHI Inspector (American Society of Home Inspectors, Member #260507) and certified inspector with InterNACHI (International Association of Certified Home Inspectors).


I follow the Illinois Standards of Practice during my home inspections. I encourage my clients to read over these standards before receiving an inspection, it will help you understand what I inspect and the inspection process. It’s always great to know these and come with any questions if you have them.

In my spare time I am a volunteer firefighter and emergency medical responder for Cottage Hills Fire Department. I enjoy being outside, riding my motorcycle, grilling, swimming on the lake, playing golf and shooting at the range. I am very much so an outdoors type person.
