Mold blossoms in a flooded house. It poisons the building and the only way to get rid of it is to gut everything and start over.
Some days, I would go out with crews armed with crowbars and sledgehammers. We would destroy someone's ravaged kitchen, tear apart their bedroom closets and disintegrate their living room until only the studs and load bearing skeleton of their home remained.
Other days, I would go back to those houses with bleach and white latex paint and do what we can to eradicate the colonies, all the while wondering if we were helping or prolonging the inevitable.
I'd like to go back one day and see what's become of these places.
