Make sure that when you hire a home inspector, who also does thermal imaging, that you hire one who has also been properly trained in how to use the imager. Many inspectors buy an infrared camera, but never take the training courses or become properly certified. All our inspectors are Infared Certified and properly trained on infrared equipment and building science.
First, let’s clear away some common myths about thermal imaging:
- Thermal imaging DOES NOT see through walls. The camera is very sensitive and can distinguish very minor differences in surface temperatures, it can not look through solid material. Forget about the things you have seen in spy movies.
- Thermal imaging sees differences in temperature. If an area appears to be cold, that DOES NOT automatically mean that the area has water. It can mean excessive moisture, but it can also just be cold. That is why it is so important for the thermographer to be fully trained and to check out suspicious areas with other tools, such as a deep probing moisture meter.
- Training is very important. Anyone with $250 can purchase a cheap clip on thermal imager for their cell phone. While these toys are cool, they are not professional grade equipment and are not being used by a trained and experienced thermographer. False positives are just as damaging as missing a real problem.
