Mildew smell from crawlspace
I believe the strong mildew smell in my crawlspace is comming from the 40 yr old insulation overhead.The stink seeps up into the living spaces of the home. The old insulation is dark & looks in very bad condition. The home is on the Missouri/Arkansas border on a lake. HIGH humidity. I suspect that is where the smell is comming from.
1) How do I know for sure if thats my problem
2) I am think of having a contractor tear it all down & spray on insulation above the crawlspace. Is this expensive. 1800 sq foot single floor home ( avg 4 foot high crawlspace)
Thanks for your inputs.
