Walk out basement
House wrap behind vinyl siding over OSB
Unfinished basement walls
Trapped moisture behind vapor barrier on all but poured foundation portions.
Fiberglass batt insulation.
OSB not affected yet where checked
Minor organic growth. No odors.
I usually recommend removal of vapor barrier to let it breathe and dry out completely along with the use of AC and dehumidifier.
Any other views on this issue?
