I decide to clean filter on window AC unit. Find water damage to wall and floor behind boxes. Two boxes of books are ruined with black mold. I toss them but am concerned I breathed in the spores. Took colloidal silver to hopefully prevent illness, but suspect I will be sick anyway. Hopeful homeowners insurance will cover my mom's neglect, leaving boxes in front of window, blocking water damage evidence for a long period of time. BTW the unit was full of black yuck and what I think was slime mold. Been in place a few years. Water damage is BAD. Drywall wet, poked a hole in it, flooring in front of window warped, cupping. I imagine water traveled from drywall to flooring. Still live with power. Black mold and his friends, good stuff for a Asthmatic to breathe in.
