What is Thermal Imaging and What Does It Do

Updated: Sep 29

There are many things a home inspector cannot see with a naked eye so hiring a company that uses thermal imaging as part of their process is a plus. Don’t assume that your home inspector offers this service or doesn’t charge more for it. Take your time, ask questions, and find the right home inspector for you.

What is Thermal Imaging?

Thermal imaging using a Forward Looking Infrared (FLIR) camera, Infrared Camera, IR, or video to look at the inside and/or outside of a structure. It looks for everything from moisture, infestations, to rook leaks, and energy loss.


Colors on the Infrared Camera

The most common colors you will see are red, white, yellow, and light colors for warmer to hot areas. When you see blue to black colors, it means the area is cooler.


Common Areas to Inspect

  • Exterior Walls

Thermal Imaging can be used to check for any penetrations on the outdoor walls, doors, and windows. It can also check where the chimney meets the wall and roofline.

  • Plumbing Fixtures

Checking around all the fixtures and appliances, this imaging reveals moisture where it shouldn’t be. Make sure the home inspector is looking around sinks and their base, toilets, ice makers, bathtubs, and refrigerators. A good rule of thumb; if it uses water, you need to check it.

  • Structural Defects

Using Infrared Imaging is a good way to check for structural issues without invasive testing. Everything from water leaks, damaged framing, or missing insulation can show up on the camera.




Buying a home is no small investment. You want to make sure you are providing a safe and relatable place for you and your family. Whether it’s new construction, 2 years old, or 60 years old, do not skimp on inspections.
