Post-Flood Mitigation in Crawlspace - Fiberglass Insulation #153155

Asked September 17, 2013, 5:36 PM EDT

We live in Boulder and our vented crawlspace was flooded in the recent disaster.  The flooding occurred when the water table rose.  We waited, and the flooding receded when the water table lowered.  We are using a commercial fan to exhaust air from the crawlspace in an attempt to dry it.  We are on a very long waiting lists for help from remediation companies.  In the meantime, should we remove the wet fiberglass insulation from the walls and ceiling of the crawlspace?  Where can we learn more about whether the crawlspace should be insulated (once it dries out) and what type of insulation is appropriate.  Thanks

Generally it is best to remove the insulation to aid drying. Continue to pull air through the crawl space. There is some information at Also check ndsu flood information.
