The IICRC WRT body of knowledge recommends usinginfrared (IR) cameras and moisture sensorsto help determine the perimeter of wet carpet and cushion during the initial inspection. These tools allow restorers to quickly and non-destructively identify moisture patterns across large areas.

IR cameras can highlight temperature anomalies caused by evaporative cooling, while moisture sensors provide confirmation of moisture presence beneath carpet surfaces. The WRT manual stresses that IR imaging must always be verified with moisture detection instruments to avoid false positives.

Disengaging carpet or relying on touch is invasive, time-consuming, and unreliable. Borescopes and anemometers are not designed for carpet moisture detection.

Using appropriate detection tools supports accurate scoping, efficient drying design, and defensible documentation—core principles of professional restoration practice under the IICRC WRT standard.
