There has been water problems under the house, new gutters have been installed a ditch dug to pipe water away from house. Now I am fixing to have insulation replaced under house. Most insulation has fallen down due to the excess water. It is dry now but there is a mold smell in my den. Under this room most of the insulation has fallen down, and what's left has mildew spores on it. Also the floor joyce has mildew. The floor is not rotted, just a few areas show water stain. Will it help with the odor if I have the area sprayed to rid the mildew before my insulation is installed. The odor has come through my floor and carpet. I need to get rid of this odor, please help.
