Here’s something you don’t see every day – a water damage company using infrared cameras. Some water extraction companies use infrared because they help detect surface temperature differences in your property. How do they work exactly? Well, an infrared camera produces a thermal image that shows temperature variations on surfaces, this makes spotting the moist areas all the more easier. Although they do not technically indicate moist areas, they do signal warmer and cooler areas, which can indicate the presence of moisture.
Infrared cameras can be especially useful when scanning large properties, it just helps the company be extra careful. Materials that appear cooler to the IR camera are usually due to an evaporative cooling effect on the surface, cooler temperatures inside walls being conducted to the surface, thermal bridging where heat or cold are transferred from one area to another via an object or material, or reflected heat or cold from another source.
You should also keep in mind that cooler readings do not necessarily mean that moisture is present. The most innocent of things can explain the change in temperature, like the air conditioning hitting a specific area more often. Non-porous materials that do not allow evaporation and reflective materials that do not allow accurate temperature information to be transmitted to the camera can result in an inaccurate reading of the temperatures. If an area is suspected of having moisture because of the reading, a check-up is followed using a moisture meter.
