When a Nashville homeowner contacted Claro, there were no obvious warning signs—no visible mold growth, no musty odors, nothing you could point to and say 'that's the problem.' But his wife, who had suffered from mold-related illness in the past, had begun experiencing familiar symptoms again.
For someone with previous mold sensitivity, even subtle exposure can trigger a response. The homeowner knew better than to wait for visible signs. He called Claro for testing.
Claro's team conducted comprehensive air quality testing in the home's living areas. The results revealed what the family couldn't see or smell: elevated mold levels were present indoors.
The Overall Mold Source Assessment showed a score of 221—significantly elevated. Penicillium/Aspergillus types dominated at 221, with total exposure levels reaching 3,400 spores per cubic meter indoors compared to just 821 outside. Additional species including Cladosporium (112), Basidiospores (100), and others were also detected.
The indoor mold burden was more than four times higher than outdoor levels. The wife's symptoms weren't coincidental—they were a response to genuine contamination that simply hadn't become visible yet.
Based on the testing results, the homeowner moved forward with professional remediation. Claro performed a comprehensive dry fog treatment to address the hidden contamination throughout the home.
Post-treatment testing confirmed the intervention's success. Culturable air fungi levels dropped to less than 13 CFU/m³—essentially undetectable. All tested mold species came back below detection limits. The indoor air quality had been restored to normal, healthy levels.
This case demonstrates an important principle: trust your body's signals, especially if you've experienced mold sensitivity before. Hidden contamination is still contamination—and catching it early, before it becomes a visible problem, can prevent months of illness and far more extensive remediation down the road.
