Structural drying is what happens after the standing water is gone. Framing, drywall, subfloor, cabinets and the top of the slab all hold water that a fan cannot reach. The drying team sets up a controlled drying system and measures it every day until the materials match a dry reference in the same building.
How the drying system is sized
- Class of loss: Class 1 is a small area of low-porosity material; Class 4 is dense material like hardwood, plaster or concrete that holds water deep
- Air movers: set to the room's evaporation load, aimed along wet walls and under cabinets
- Dehumidifiers: LGR units for most losses; desiccant units for Class 4 materials and cool spaces
- Specialty tools: wall cavity injection, hardwood drying mats and heat when needed
What the daily readings show
Each visit, the drying team records the moisture content of the wet materials at marked points, plus the temperature and humidity of the air inside and outside the drying area. Those psychrometric readings show whether the dehumidifiers are keeping up. When a material stops dropping, the setup gets adjusted: more airflow, a different dehumidifier, or opening a cavity that is trapping water.
Why not just run box fans? Fans move surface air. Without dehumidification, the moisture they lift ends up in the rest of the house, and water inside walls and under floors stays put.
North Texas humidity and drying
Lewisville summers are hot and humid, and spring storm weeks keep the air wet. Opening windows usually adds moisture rather than removing it. A closed drying area with LGR dehumidification controls the air so evaporation keeps going. The EPA moisture control page explains why materials need to dry quickly, and the U.S. Department of Energy covers how humidity and cooling interact in a home.
