Infrared thermal imaging is an advanced technology used to detect and image thermal infrared energy not visible to the "naked eye". Every material has a unique thermal signature which can change when moisture, heat or cold is introduced. Thermographic imaging cameras detect and capture these temperature changes in the thermal images. By examining and analysing the thermal variations in these images we can assess what's potentially going on behind the surface.
What makes thermal imaging so useful is that defects that would normally go undetected during a visual home inspection can be now be detected before they cause extensive damage. Early detection of water leakage in a wall, for example, can prevent a much larger problem involving substantial wood rot, structural weakening and mold growth.
Infrared thermal imaging can help detect a variety of hidden problems that visual inspection can't determine, such as:
