Thermal Imaging Technology

In January of 2014 Northwest Home Inspector adopted the use of infrared thermography and radio frequency moisture detection tools.  Since then we have invested in several more advanced, industrial-grade FLIR thermal cameras and moisture meters. These devices are absolutely essential for performing a deep-scan in order to detect potential hidden issues on your home inspection.


Both Gregory and Jesse are Certified Residential Thermographers by Monroe Infrared Technology as well as Certified Infrared Technicians by InterNACHI.  We have committed to countless hours of training and real-world experience using this technology.  Mastering the use of these has allowed us to discover previously hidden clues and characteristics about every home we inspect.  In the right conditions we can detect plumbing leaks, roof leaks, missing insulation, energy loss, electrical dangers, rodents, and even clues for termites.  This technology is an absolute game-changer when applied correctly to a home inspection.


Thermography does not put out any kind of radiation and cannot see "through" walls. Instead, it displays the light spectrum beyond what the naked eye can see on surfaces. This light shows up brighter where there is more heat and darker where there is less heat. When moisture is present a phenomenon called "evaporative cooling" takes place which makes that area much cooler than its surroundings.  With a sensitive enough thermal camera and a good moisture meter we are able to pinpoint hidden moisture issues with precise accuracy.


You should know that a home inspector can buy a hobbyist grade thermal camera for a few hundred dollars and advertise "We have thermal".  But, that is light years away from a company like Northwest Home Inspector who invests thousands of dollars into commercial equipment and rigorous training specialized for our industry.  Not all inspectors who offer thermal services are the same.


* When scheduling your thermal inspection please turn the heat up on a cold day or try to cool the home (turn on AC) on a hot day before your appointment time.  The more contrast between outside and inside temps will allow the camera to operate at its peak performance.
