Dry air is simply air that is significantly lacking moisture. Equally important, air with low relative humidity is generally under 40%. That means dry air falls below the ideal 40% to 60% indoor humidity range. Generally speaking, when humidity levels are below this range, the air is noticeably dry. 

Advanced Structural Drying (ASD) is the effective and efficient drying of water-damaged buildings and homes, using comprehensive knowledge and tools. The process includes the collection of data appropriate to the use and application of scientific and technical principles.

Mold in your home is almost always bad news. Mold is a fungus designed to digest dead trees into forest soil, but it can’t tell the difference between a house and a tree. It likes to grow in any material that is saturated with moisture, and it only has to be soaked once for the mold to start a colony. From there, it will try to live off the moisture in the air and any nutrients it can eat from the new home. Mold likes to grow in drywall after a leak, furniture after a flood, and can take hold in the carpet with just a spill that dries slowly. It can eat away at structural beams and cause roofs to sag.
