Case Study: Complete crawlspace replacement resolved family allergy symptoms

A Sandy Springs mother and her daughters had been experiencing allergy symptoms for months. The family's poorly encapsulated crawlspace required replacement, and humidity management was an ongoing issue throughout the home.

For families with allergy-sensitive members—particularly children—crawlspace moisture problems create conditions for contamination that affect air quality throughout the entire home. When symptoms persist for months, professional intervention is needed to identify and correct underlying moisture issues.

Claro's inspection revealed the poorly encapsulated crawlspace was the primary source of humidity and contamination affecting the family. The hallway/laundry room testing showed 1,400 total spores with multiple concerning species. Chaetomium registered 27 spores—a water-damage indicator confirming moisture problems. Stachybotrys showed 13 spores—a toxic species associated with water damage. Basidiospores reached 1,100, Penicillium/Aspergillus 160, and Cladosporium 110.

The inspection also uncovered multiple water damage areas throughout the home: hidden window leaks creating moisture intrusion, and a garbage disposal leak causing cabinet damage. These moisture sources combined with the failed crawlspace encapsulation to create conditions for mold growth affecting the entire home.

With a mother and daughters experiencing months of allergy symptoms, the presence of both Chaetomium and Stachybotrys indicated serious water-damage contamination. The humidity management issues stemming from the crawlspace were creating indoor conditions that triggered constant allergic reactions in sensitive family members.

Understanding that crawlspace moisture was affecting the entire home and that allergy-sensitive family members required comprehensive intervention, Claro provided guidance and assistance with complete crawlspace encapsulation replacement. The team addressed multiple water damage areas including hidden window leaks and garbage disposal leak with cabinet repairs.

Post-treatment testing confirmed complete elimination of contamination. The hallway/laundry room dropped to 800 total spores with all toxic species eliminated—no Chaetomium, no Stachybotrys, no Penicillium/Aspergillus, no Cladosporium. Only Basidiospores remained at 800, which are common environmental spores not associated with water damage.

The mother and daughters could breathe clean air free from the water-damage species that had been triggering their allergy symptoms for months. The humidity management issues were resolved through proper crawlspace encapsulation, and the hidden water leaks were addressed to prevent recurrence.

The results were so successful that the family's parents are now having Claro perform full crawlspace encapsulation at their own home—a testament to the comprehensive solution that protected their daughter and granddaughters. This case demonstrates why persistent allergy symptoms in families require professional investigation of crawlspace moisture and hidden water damage sources.
