An infrared camera or thermal imaging camera allows infrared radiation to be seen and displays this information as gradient colors on the display screen. Being certified in Infrared technology, we use this information to look for anomalies or deficiencies in the images presented. When using an Iron contrast setting (as seen on the images on this page), cooler temperatures are represented in darker colors (blues and purples), while warmer temperatures are represented in brighter colors (yellows and oranges). The differences in these temperatures is called the Delta-T.
Thermal imaging is invaluable for detecting potential moisture issues. When moisture is present in a material or surface, it is constantly evaporating. This process of cooling during evaporation (when liquid is converted to gas), is called evaporative cooling. An infrared camera is so sensitive that it can pick up the Delta-T or temperature differential from this process taking place, alerting to the potential presence of moisture. The presence is then verified with a moisture meter to get an exact reading of the moisture content.
On the other end of the spectrum, an infrared camera is great for finding electrical deficiencies that cannot be seen with the naked eye. Improperly tightened electrical lugs and terminals in electrical panels can allow conductors to overheat and create a fire hazard. Without an infrared camera, this would go undetected.
During a home inspection, a selective scan of the home is conducted, focusing on potential defects and moisture intrusion, as well as an electrical panel scan for possible overheated components. Infrared photos of these areas are included in the inspection report, if deficiencies are found. A full thermal imaging inspection of the home is available for an additional fee, if requested. A full thermal imaging inspection can detect missing insulation in walls, energy loss around doors and windows, overheated branch wiring, etc.
Thermal Imaging Inspection
Home Inspection Deficiency Examples
The images below show moisture on a garage wall that was picked up during a Home Inspection in New Tampa, Fl. and a cold air duct missing the diffuser during new home pre-walk through inspection in Lutz, Fl. The moisture or cold air is represented in purple (cooler temperature). Without the Infrared camera, the moisture or blocked duct would most likely have not been detected until visible damage was present.
