The source of water leaks can be difficult to detect without intrusive (and expensive) methods and can cause long term damages to buildings as well as posing a health hazard to occupants through mould growth.
A thermal camera inspection is a non-contact, non-invasive and visual way to show water leaks and moisture ingress within the built environment and often the source of the leak is not where the water appears. The colder a wall, roof or floor is, the more moisture is present. A thermal camera can detect the heat difference between the temperatures of different materials. Water leaks cool walls and floors through evaporation, making them cooler than areas not affected by water. It is this temperature difference than can be seen by using a thermal camera.
Thermal cameras can detect water leakage without any moisture being directly visible on a wall or other surface and can be used to detect the source of the leak.
