I have hanging or fallen insulation, does it need to be replaced?

/ Triangle Crawl Space Solutions/

This depends on whether the insulation has become wet or moldy. If the insulation is dry it can often be rehung or a damaged portion can be replaced. If your insulation is wet, moldy or a low R-value, it should be replaced.  Current NC code specifies R19 insulation. If your home is older it may have R11 between floor joists and we recommend upgrading to R19 for maximum efficiency.
