What does thermal imaging detect during a home inspection?

Thermal imaging is an advanced technology used during home inspections to detect variations in surface temperatures. It works by using infrared cameras to visualize and measure heat emitted from objects, allowing inspectors to identify areas that may require further evaluation.

The primary benefit of thermal imaging lies in its ability to reveal temperature differences that are often synonymous with insulation deficiencies, air leaks, and moisture intrusion. For instance, cooler areas on a thermal image may indicate that insulation is inadequate, resulting in heat loss, while warmer areas can suggest hidden moisture or dampness, potentially leading to mold growth.

While cracks in walls, electrical issues, and pest infestations may all be of concern during a home inspection, these conditions do not directly correlate with the capabilities of thermal imaging technology. The focus of thermal imaging is fundamentally on thermal signatures and variations in surface temperatures, which are critical in assessing the thermal integrity and overall condition of a home.
