Abstract
The invented method can be applied to a house, building or other structure to detect the presence of a water problem, even in areas that are not visible to the naked eye. The method includes a step of changing the temperature of the structure relative to its temperature existing immediately before the start of the method. The method also includes a step of infrared scanning the structure. Because moist structure areas are slow to move to the changed temperature compared to dry areas due to the relatively high thermal capacity of water, the changed temperature enables the infrared scanning step to readily contrast moisture-suspect areas of the structure from dry areas thereof. The method can also include steps of determining whether a moisture-suspect area does in fact contain moisture, or is due to other causes unrelated to moisture. If moisture is determined to be present in the moisture-suspect area, the method can also include a step of determining the source of the moisture by sampling and analyzing the moisture.
