No vapor barrier on the ground, but what about the insulation below the sub floor?

If the insulation was installed with the vapor barrier to the crawl side insteas of to the conditioned side of the home, it can and will cause just what you are describing. After absorbing humidity and holding moisture for a while, the insulation usually falls to the crawl floor, but the wood will remain wet for a long time. The longer it remains wet, the more it will mold which retains even more moisture. Before you know it, you can berak chunks off of it with your bare hands.


Pictures would have been nice. I average around 100 pics/inspection. Not all of them go into my report, of course, but they are nice to have. If nothing else, to share with your friends here at InspectionNews.net

BTW, I keep all pictures in case they are needed in the future.
