Mold
The Crawford County Health Department does not preform mold removal, however we play an important role in helping residents understand risks and take appropriate action. We may offer guidance on cleanup and prevention, and help connect residents with resources or services.
What causes mold?
Mold is caused by excess moisture. It can develop when there are water leaks, flooding, high humidity, condensation, or poor ventilation in a home or building. Common sources include leaking roofs or pipes, damp basements, improperly vented bathrooms, and areas where water has not been fully dried. When moisture is present for 24–48 hours, mold can begin to grow and spread on surfaces such as wood, drywall, carpet, and insulation.
Is mold dangerous?
Mold is a type of fungus that grows in damp environments and can affect indoor air quality. Exposure to mold can cause health effects, especially for people with allergies, asthma, or weakened immune systems. Common symptoms include coughing, sneezing, nasal congestion, eye irritation, and skin irritation. While not all mold is toxic, any visible mold growth should be addressed promptly.
What if my rental apartment has mold?
If you live in a rental unit and discover mold, notify your landlord or property manager as soon as possible in writing. Landlords are generally responsible for maintaining safe and habitable living conditions, which includes addressing moisture problems and mold caused by structural issues or leaks. Avoid attempting large-scale cleanup yourself, especially if the mold is widespread. Keep records of communication and take photos of the issue. If the problem is not addressed, you may contact the Crawford County health department for guidance on next steps.
Do I need to leave my home if there is mold?
In most cases, you do not need to leave your home for small areas of mold. However, if mold is widespread, caused by significant water damage, or if household members are experiencing health symptoms, temporary relocation may be recommended during cleanup. Children and individuals with asthma, allergies, or weakened immune systems may be more sensitive and should take extra precautions. Prolonged exposure may increase the risk of respiratory issues.
How can I prevent mold from coming back?
Preventing mold starts with controlling moisture. Fix leaks promptly, use exhaust fans in bathrooms and kitchens, and keep indoor humidity levels low (ideally below 50%). Use dehumidifiers in damp areas, ensure proper ventilation, and clean and dry any water-damaged areas within 24–48 hours. Regular maintenance helps reduce the risk of mold returning.
Does flooding increase the risk of mold?
Yes, flooding significantly increases the risk of mold growth. Mold can begin to grow within 24–48 hours after water exposure. After a flood, it is important to remove water quickly, dry out the home thoroughly, and clean and disinfect affected areas. Materials that cannot be fully dried should be removed to prevent mold growth.
Can I clean mold myself, or do I need a professional?
Small areas of mold (generally less than 10 square feet) can often be cleaned by homeowners using proper precautions. Clean hard surfaces using a mixture of 1 cup of bleach per 1 gallon of water. Never mix bleach with ammonia or any other cleaners, as this can create dangerous fumes. For larger areas, mold caused by contaminated water, or situations involving HVAC systems, it is recommended to hire a professional mold remediation specialist. Professionals have the equipment and training to safely remove mold and prevent further contamination.
