I am certified in mold remediation.
Everyone who did clean up was exposed to mold.
After Sandy, the weather warmed up enough to breed mold quite rapidly.
The 2/3 week wait most had before they could get back into their barrier island homes insured plenty of mold growth.
I have some mold pictures from my own house on LBI that would blow your mind.
In particular, I had a dresser get wet 12″ up, the whole back 4′ up was covered by the time we got in.
*My house is newer construction, very tight from an airflow standpoint. Allowing faster growth.
No one was told how to handle mold, or to protect themselves from “fragmenting” it.
