Possible Hidden Stachybotrys + Philadelphia Mold Testing Investigation
"Sage" called for a mold inspection at her apartment because she was experiencing respiratory symptoms. She knew there had been a roof leak affecting the ceiling near her bed and had the ceiling drywall replaced. As a precaution, she had me check the area several months later. Here are my findings and recommendations, which may be applicable to a concern in your home:
- No mold was visible, but my moisture meter revealed that the leak was still active. Ceiling drywall tested positive for elevated moisture.
- The roofer needed to be called to have another go at repair.
- Sage couldn't afford to hire a professional mold remediator, so I explained the steps the maintenance staff should take for safe clean up.
- These steps include use of personal protection (with an N95 respirator and goggles), plus advice on how not to spread stray mold spores around.
- Follow the path of the water. Not only is the ceiling an issue but also down behind built-in wood cabinets.
- Chronic leakage at drywall (with its paper backing) is a favorite spot for Stachybotrys mold, and the risk was high for mold on the back of the drywall.
- Even though this is a common mold, Stachybotrys has been linked with neurological damage, such as memory loss and decreased ability to multi-task, so take reasonable precautions to avoid exposure.
- I suggested that Sage sleep in the guest bedroom until the area is remediated.
- Finally, just in case the new roof repair still doesn't hold, I suggested that either paperless drywall or cement backer board be used, so that if it gets wet, the risk of mold growing will be much less.
