Water leaks or spills are very common. Immediate inspection of floor coverings, structural materials, and crawl spaces, as well as prompt removal of all standing water, is critical to reduce or eliminate structural damage and/or the possibility of mold.
Homeowners sometimes remove standing water themselves, then neglect to have the area professionally dried because the surfaces look dry or feel dry to the touch.
However, without the proper equipment, it is impossible to determine how much moisture is still within the structure or to draw that moisture out before it cultivates mold or causes other structural damage. Increased moisture in the air after an indoor flood can also cause damage to decorative wood, books, artwork, and other items, so thorough drying and de-humidification is critical.
