Thermal imaging in home inspections reveals potential problems in the house undetectable to the naked eye. Thermal or infrared imaging captures the heat signature of an area, and the colors show cool or warm spaces in a home that may signify issues with the property.

An inspector who uses thermal imaging during an inspection will detect otherwise hidden issues. The information in the inspection report will help you make a smart decision and avoid potentially expensive and dangerous problems.

Electrical Hazards can be Detected with Thermal Imaging in Home Inspections

A home inspector might use a thermal camera to check the electrical panel for overheating. Likewise, the walls can be scanned to look for hot wiring. When performing a thermal scan, potentially dangerous electrical hotspots show up as warmer areas on the image. Without a thermal scan, these issues would go undetected.

Thermal Imaging Finds Moisture in a Home

When an inspector uses infrared imaging to examine a water stain, the variation in color indicates if it’s an active moisture problem or an old stain. This technology detects the temperature difference between the water stain and the rest of the wall.

A lower or cooler temperature means there are current moisture issues. The heat signature reading may also reveal hidden water leaks in walls that would go unnoticed without thermal imaging technology.


Areas of a home that are not insulated or under-insulated will show as cooler areas on an infrared image. Thermal imaging can pinpoint missing or damaged insulation that needs to be replaced. An infrared camera can also reveal gaps around windows and doors that contribute to heat loss. Replacing the weatherstripping will make your home more comfortable and energy-efficient.

Pest Infestation

Thermal imaging cameras can identify pest infestations in the home. The camera will read the temperature of a rodents’ nest at a higher temperature than the surrounding area. This technology can also be used to find moisture problems that may lead to a termite infestation. Your home inspector will interpret the images to point out potential or existing pest problems in your home.
