Why is it recommended to dry structures from the bottom up?

Drying structures from the bottom up is recommended primarily to effectively remove moisture that has migrated to lower areas. In water damage restoration, moisture often collects in lower sections of buildings, such as basements or ground floors. By starting the drying process from these areas and working upwards, restorers can ensure that they adequately address the source of the moisture and prevent further damage.

If the drying process were to begin from the top and work downwards, the moisture in the lower areas could remain trapped, leading to prolonged conditions that facilitate mold growth and structural integrity issues. Therefore, focusing on the lower areas first allows for the most efficient removal of moisture and helps to mitigate the overall effects of water damage.
