I am Mike St John, owner and Inspector of Checker Home Inspection LLC, a professional local home inspection Co. located in Greenfield WI. 

I have been inspecting homes for 5 years. What is just as important is my previous experience in Electrical , Maintenance, HVAC and Boilers. All of this experience blended together to develop a better inspector for you.
