Infrared Imaging and Cavity Access
Thermal imaging reads surface temperature differentials across walls, ceilings and floors. Because evaporating moisture cools a surface, water that has migrated inside an assembly shows up as a distinct thermal pattern long before it becomes a visible stain. Borescope inspection complements this by putting a camera directly inside a wall cavity, soffit, chase or subfloor void through a small access port, giving us a live view of framing, insulation and the back side of finishes without opening the assembly.
