- Brief explanation of Indoor Air Quality (IAQ).
- Overview: How the condition of a crawl space affects the air inside the home.
- Statement of problem: Moisture, mold, and contaminants rising into living spaces.
2. The Crawl Space–IAQ Connection
- How air naturally moves upward (stack effect) through HVAC returns, vents, and subfloor.
- Percentage of air in living spaces that originates from the crawl space.
- How poor crawl space conditions contribute to:
 - Allergens
- Mold spores
- Musty odors
- Pest contaminants (rodents/insects)
 
 
 
 
 
 
 
3. Common Health Risks Caused by Unsealed Crawl Spaces
- Mold growth and respiratory irritation
- Increased allergies / asthma triggers
- Humidity that worsens dust mites
- VOCs from soil gases or decaying organic matter
Optional: Include statistics or medical insights here.
4. How Crawl Space Encapsulation Improves IAQ
- Vapor barrier seals ground moisture
- Air sealing prevents contaminant infiltration
- Dehumidifiers keep humidity at healthy levels
- Cleaner air reduces mold and allergen levels
5. Benefits to Homeowners
- Health: Reduction in allergy and asthma symptoms
- Comfort: Less humidity and fewer musty odors in living areas
- Cleanliness: Less dust circulating through HVAC system
6. Supporting Technologies
- Smart humidity monitoring
- MERV and HEPA air filtration
- HVAC integration with encapsulated spaces
7. Case Example (Optional Section)
- Real-world example: Before encapsulation (mold, moisture), after encapsulation (reduced humidity, improved IAQ)
8. Conclusion
- Encapsulation is not just a structural upgrade — it is a health improvement.
- Encouragement to view crawl space work as part of an overall IAQ strategy.
