The short answer
What Is Aspergillosis?
Aspergillosis is an infection or allergic reaction caused by inhaling spores of the Aspergillus mold. This fungus is common in the environment, often found in decaying leaves and compost piles. For most people with healthy immune systems, exposure does not cause illness. However, it can lead to serious respiratory issues for those with lung conditions or weakened immune defenses.
The primary concern in a home is when a large, hidden colony of Aspergillus grows, often due to chronic moisture. Disturbing such a colony during a DIY cleanup can aerosolize a high concentration of spores. This creates a significant inhalation hazard. If you suspect a major mold problem, especially with visible black growth, consider consulting a qualified mold professional for assessment.
Safe Mold Remediation Practices
Proper mold removal focuses on containment and source elimination. The pros seal off the work area with plastic sheeting and use negative air pressure machines to prevent spores from escaping into other parts of your home. They wear protective gear like respirators and disposable coveralls to avoid carrying spores out of the containment zone.
The actual removal involves carefully discarding porous, heavily contaminated materials like drywall or insulation. Non-porous surfaces are cleaned with specialized antimicrobial agents. The area is then dried thoroughly to prevent regrowth. This methodical approach minimizes airborne spore counts, protecting you and your family from unnecessary exposure during and after the cleanup process.
- Sealing the affected area with containment barriers.
- Using negative air pressure and HEPA air scrubbers.
- Wearing full personal protective equipment (PPE).
- Safely removing and bagging contaminated porous materials.
- Cleaning and disinfecting remaining structural surfaces.
- Completing the job with thorough drying and verification.
Risks of Do-It-Yourself Cleanup
Attempting to remove mold yourself without proper precautions is a key way to cause a spike in airborne spores. Common actions like scrubbing, sanding, or demolition can send a cloud of spores into your living space. Without containment, these spores can settle in new areas, potentially starting new colonies if moisture is present there.
You also risk personal exposure. Inhaling a large dose of Aspergillus spores can trigger allergic reactions or, in rare cases, lead to infection. Symptoms might include coughing, wheezing, or shortness of breath. If you feel unwell during or after a DIY cleanup, it is important to see a doctor and inform them about your mold exposure.
When to Involve a Professional
You should consider professional mold remediation if the affected area is larger than about ten square feet, or if the mold is in your HVAC system. If anyone in your household has asthma, allergies, or a compromised immune system, professional help is strongly advised to ensure safety. A professional assessment can determine the extent and type of mold present.
A professional assessment can determine the extent and type of mold present. Mold professionals use tools like moisture meters and borescopes to find hidden moisture and growth that can occur in crawl spaces, behind walls, or under sinks from slow leaks. They can then develop a safe, effective removal plan tailored to your specific situation.
Preventing Mold After Water Damage
The best way to prevent aspergillosis risk is to prevent the mold that causes it. After any water leak or flood, rapid drying is critical. Start water extraction immediately and use fans and dehumidifiers. Remove wet carpets, padding, and furniture that cannot be dried completely within 24 to 48 hours to deny mold a food source.
Address the source of the moisture permanently. Repair leaking pipes, seal foundation cracks, or improve ventilation in damp areas like bathrooms. Regularly check under sinks, around windows, and in basements for signs of moisture. Keeping indoor humidity below 60% helps create an environment where mold struggles to establish itself in the first place.
- Extract standing water and remove saturated materials promptly.
- Use industrial air movers and dehumidifiers for structural drying.
- Discard porous items like carpet or drywall that stayed wet over 48 hours.
- Fix the leak or intrusion that caused the water damage.
- Improve ventilation in bathrooms, kitchens, and laundry rooms.
- Monitor indoor humidity levels with a hygrometer.

What are the symptoms of aspergillosis I should watch for?
Symptoms range from allergic reactions like wheezing and coughing to more serious fever and chest pain in invasive cases. People with existing lung problems are at higher risk. If you have been exposed to disturbed mold and develop respiratory issues, see a doctor and mention the possible mold exposure.
Will my homeowner's insurance cover mold removal?
Coverage depends on the source of the water that caused the mold. Sudden, accidental events like a burst pipe are more likely to be covered than long-term neglect. Policies vary, and your insurer decides what is covered. You should review your policy and document the damage thoroughly.
Can I clean a small mold patch myself safely?
For a patch smaller than a standard sheet of paper, you can clean it with detergent and water while wearing an N95 mask and gloves. Ensure the area is well-ventilated. However, if the mold returns quickly or you have health concerns, stop and consult a mold professional for a proper assessment.
