After the Storm: Damp, moldy homes

See the full report

The risks from heavy rains and flooding don’t pass with the storms. Buildings exposed to flooding are left wet, damaged, and potentially harmful to health. Dampness can support the growth of mold and other organisms—contributing to poor indoor air quality and a range of potential health problems. Remedying water damage to reduce health risks is an important part of storm recovery.

As flood risks increase due to climate change, more people are vulnerable to health problems from damp, moldy homes after the storm. Communities across the United States are increasingly vulnerable to damaging floods due to more intense storms and rising sea levels—all exacerbated by climate change.

This research brief provides background information and summarizes Climate Central’s analyses on weather and climate trends that influence flood risk. These resources can help explain and report on the health risks from poor indoor air quality after floods, and the connection to climate change.
