We are renting a mobile home in anchorage alaska. and obviously it has water damage. It was like this when we moved in about 7 months ago, but we didn't see what I suspected is mold at that time until taking a closer look. Anyone have any insight on what im looking at here? I've just never seen anything like this before and ive been pretty sick since moving, so am feeling a bit anxious.
