The questions we hear most about toxigenic mold.

Stachybotrys chartarum specifically has been linked to respiratory symptoms in some occupants, especially with prolonged exposure.
For extensive contamination, we may recommend temporary relocation, especially for anyone with respiratory sensitivity.
The underlying goal is the same — get rid of it — but the health stakes change how carefully the process is run.
Visual color alone isn't reliable — several mold species and even some dirt or mildew look similarly dark.
Coverage depends on your policy and the underlying cause of the moisture, so it's worth a call to your insurer.
