Crawl Space Repair - Water Damage on Wooden Beams

The water has also started to affect the beams in the crawl space, although not to the degree that we sometimes see. Note the discoloration on the insulation. In damp environments, as the insulation absorbs ambient moisture it starts acting essentially like a coffee filter. So any dirt or debris in the air is caught by it, adding to the weight and causing it to eventually fall.
