The Delaware Division of Public Health (DPH) reminds Delawareans of the importance of completely cleaning and drying any home or business hit by excessive rain or flood waters to prevent mold.
Here is the list of tips to fight mold following flooding:
- Remove standing water through water pumps and fans.
- Remove damaged or moldy materials (as a general rule, wallboard, carpet, furniture, etc. that has been wet for more than 48 hours should be considered for removal and replacement.)
- Use dehumidifiers to remove moisture that has soaked into building materials and furnishings that are otherwise intact.
- Do not depend only on sight or smell to determine if all mold is gone. A hygrometer (which measures moisture in the air) is an important tool to determine when drying is complete. Hygrometers can be purchased at hardware stores or on-line, and can be found for a little as $5.00 - $10.00.
- After the recovery from an event is complete, routine maintenance such as sealing foundation cracks and other water intrusion points is vital, plus monitoring/maintaining humidity between 35-55 percent as measured by the hygrometer. Even the regular cleaning and maintenance of the HVAC system can help prevent future mold problems.
