An experienced home inspector can almost predict which defects will be present in any particular home based on age and/or location. Several factors allow us to do this. Homeowners are more likely to have performed electrical, plumbing, and other miscellaneous work personally in older homes. If this is the case, it becomes more likely the work was performed incorrectly. In some areas there are no inspections performed by the county or municipality and the workmanship lacks professionalism. Topography also plays a role in some defects. There are certain areas that have a higher percentage of homes with elevated radon levels. So what do home inspectors look for?
