The Relationship Between Floodwater and Mold
The damage and loss from Hurricane Helene has been catastrophic and much worse than ever imagined in Florida, Georgia, Tennessee and the Carolina’s…. Many homes affected by flooding are not insured for flood damage, which is a huge contributor to mold growth. Because these losses often are not covered, homeowners will rely on other sources of assistance for repairing damage. One of the main sources is FEMA. However, FEMA assistance can take time, which is a major factor in mold growth. We’ve included some main points below about why mold is such a major concern after flooding.
Floodwater causes mold growth because it introduces moisture into environments where mold spores can thrive. Mold requires a damp, humid environment to grow, and floodwaters provide the ideal conditions. Here’s why:
- Excess Moisture: Flooding saturates walls, floors, carpets, and other surfaces with water. Mold spores, which are naturally present in the air, start growing on these wet surfaces if they aren’t dried out quickly.
- Organic Materials: Floodwater can bring in dirt, debris, and organic matter that mold feeds on. Mold can also grow on wood, drywall, insulation, and fabrics, all of which are commonly found in homes and buildings affected by flooding.
- Lack of Ventilation: After a flood, buildings often remain sealed to prevent further water damage, reducing air circulation. Poor ventilation traps moisture, making it harder to dry out wet areas, which further promotes mold growth.
- Temperature: Mold grows best in warm conditions. In many cases, flood-affected areas can become warm and humid, accelerating the mold growth process.
- Contaminants in Floodwater: Floodwaters often contain bacteria, sewage, and chemicals that can further degrade building materials, creating a more favorable environment for mold.
If floodwaters are not cleaned and dried properly within 24-48 hours, mold can quickly spread, causing structural damage and health issues.
