Why should windows and doors be kept closed during the drying process?

Keeping windows and doors closed during the drying process is crucial for maintaining controlled environmental conditions. When drying materials after water damage, it's important to regulate factors such as humidity and temperature. Keeping the environment controlled prevents the introduction of outside air, which may have higher humidity levels or different temperatures, thereby potentially hindering the drying process.

When windows and doors are closed, it allows the drying equipment, such as dehumidifiers and air movers, to operate more efficiently by concentrating their dehumidifying and air circulation efforts in a contained space. This not only speeds up the drying process but also helps in managing the air quality within the affected area. By ensuring that the drying environment is well-regulated, you significantly improve the chances of successfully mitigating water damage and preventing further complications like mold growth.
