This dryer vent was exhausting into a crawl space of this home, making it very hot, humid, and prime conditions for mold growth.

This crawl space was not properly ventilated...

...and led to this fiberglass insulation falling due to heavy condensation and moisture collection. Not what you want to see!

This insulation was installed upside down. In cooling climates like our's, the vapor barrier on the insulation needs to be placed on the Inside close to the sub-floor (Paper to the People).
