An infrared image can identify the signature of moisture present within building materials due to the cooling effect on a surface resulting from the evaporation process. When standing water or droplets are on surfaces the camera easily identifies it since IR energy can not transmit through water. These two principles coupled together effectively assist in locating moisture within the dwelling. The visual depiction of moisture from IR images can greatly assist in locating the root cause or source of water ingress. Often the infrared images result in avoiding costly destructive investigation of an assumed problem. It is nearly as more important for builders to know that a building envelope element is not the problem as knowing what is the root cause.  This is an essential non-invasive diagnostic tool for those involved in additions to older homes.  The value of the findings generally greatly outweighs the investment price of our services.
