Thermal Imagery



Ridley & Partners, Inc. utilizes multiple tools and techniques when performing standard home inspections. Thermal Imagery which is commonly referred to as thermography in the home inspection market is a technique which utilizes a thermal imaging camera to produce a thermal image of a particular area of concern. Our inspectors are equipped with thermal imaging cameras and at their discretion they may utilize this tool in the course of a standard residential home inspection.


We do not presently offer thermal imagery or thermography inspections as a standalone service offering. It is our present believe that this technology is an additional tool, for our inspectors, to utilize if required during the course of standard residential home inspection; but, is not the only or most important tool. Additionally, the use of this technology is not presently required by the American Society of Home Inspectors (ASHI) Standard of Practice (SOP). In certain circumstances and if conditions warrant we may agree to perform a through thermal imagery investigation of a property.


If our inspectors elect to utilize this tool during the course of a residential home inspection and pertinent information is obtained from its utilization the findings will be documented in the standard inspection report. We generally utilize this tool to spot check the inside of live electrical panels, to spot check certain types of HVAC systems, as well as in some instances to spot check for potential moisture related problems.


It is our opinion that this technology has multiple real world applications particularly in the heavy commercial market sector, the utility market sector, as well as the industrial market sector. Additionally, the following uses of this technology have been well documented in the home inspection market sector:


  • Building Heat Loss - In home energy audit inspections this technology can help to indicate areas of heat loss such as air bypass leaks or missing insulation.
  • Building Moisture Traps and Leaks - In general inspections this technology can help in identifying evidence of recent leaks as well as wet insulation in building cavities.
  • Electrical Overheating - In general inspections this technology can help in identifying overheating electrical components at electrical panels, electrical switches or receptacles, or at wiring servicing heavy electrical loads.
  • Tracing Heating Elements - In general inspections this technology can help in identifying the location of radiant heat tubing in floors or ceilings and finding leaks in those systems.


In all instances where this technology has been well documented in either the home inspection market or other markets the results are generally subject to the following primary issues:


  • Training - The proper use of this technology depends on the training level of the user.
  • Experience - The proper use of this technology depends on the experience level of the user with both the technology, what the technology is indicating, and if the indication is valid or a false positive.
  • Technology - The quality level of thermal imaging equipment on the market varies greatly and this quality level has a direct bearing on how the data obtained can be interpreted. As an indication this technology currently ranges in price from approximately $250 to $20,000.
  • Verification - In order to reduce the occurrence of false positives it is generally required to utilize additional equipment to verify results (moisture meters, electrical instruments, etc.).
  • Environmental Conditions - This technology is based on the production of an image based on the measurement of temperatures of an area of concern. The resulting temperature data is then converted into a color shaded image in which variation in temperatures are easily discerned. As such for building heat loss investigations it is generally necessary to have a minimum twenty (20) degree temperature differential between interior and exterior temperatures. Additionally, for electrical overheating it is not generally common to inspect a residential property when heavy electrical loading is occurring such as cooking with electrical appliances or utilizing electrically operated laundry equipment.
