What Does Wet Insulation Lead to? 

Wet insulation causes more problems than simply paying for repairs. It also leads to temperature control issues in your home. First, this can lead to high energy bills as your HVAC is forced to work harder since the insulation no longer offers proper protection. Secondly, water may leak from the insulation onto wooden structures in your crawl space. This can lead to wood rot, which causes your floors to sag and become uneven. As you can see, wet insulation can lead to a domino effect of other problem signs throughout your home and crawl space.
