Manufactures originally designed EIFS products with an intent for them to remain fully sealed. Unfortunately, when water manages to seep in an exterior wall, there is nowhere for the water to escape. There are still hundreds of thousands of homes with older EIFS installations. These installations can eventually cause potential problems that lead to structural rotting and mold and mildew conditions.
An EIFS inspection method may consist of several methods. One method is the use of a meter that allows for moisture testing through electrical impedance technology. This method can also work in tandem with a pin-type or electrode meter probe. Your inspector will have the right tools and use proper methods of inspection.
