Mold Detection and Assessment

Thermography is a valuable tool for mold detection in buildings. As a screening tool it is used in conjunction with other methods such as visual inspection, moisture meters, and mold sampling for accurate assessment and confirmation of mold presence. A mold specialist certified in both mold detection and thermography has the ability to correctly interpret inspection results.


  • Mold growth is often associated with moisture-related issues. Thermography can help detect areas of excessive moisture by identifying temperature anomalies. Moisture intrusion, such as water leaks, condensation, or damp areas, can lead to cooler surface temperatures compared to surrounding dry areas. By using thermal imaging, areas of potential moisture problems can be identified, which can be further investigated for mold growth.
  • Mold can often grow in concealed or hard-to-reach areas, such as behind walls, under flooring, or inside ceilings. These hidden mold sources may not be visually apparent. Thermography can help identify hidden mold by detecting temperature variations on the surface that may indicate the presence of mold growth beneath the surface.
  • The building envelope, including walls, windows, and roofs, can be vulnerable to moisture intrusion, which can lead to mold growth. Thermographic imaging can assess the integrity of the building envelope by detecting thermal anomalies that may indicate areas of moisture infiltration or compromised insulation. These anomalies can be indicative of potential mold-prone areas.
  • Thermography allows for quick and non-destructive scanning of large areas. By using a thermal camera, a building or room can be scanned relatively swiftly, providing an initial assessment of potential mold issues. This can help prioritize areas for further investigation and sampling.
  • The key to successful mold remediation is solving the moisture problem. Post-remediation thermography scans can be used to detect moisture or potential mold growth that might be missed via visual inspection. Regular monitoring with thermal imaging can also help detect early signs of moisture intrusion or mold reoccurrence.
