On a home inspection we found this completely clogged dryer vent exhausting into the crawl space.  Later, on the inside of the home, I turned on the dryer and smelled a burning odor.  This is an extremely dangerous situation.  I left a note for the renter and told them not to use the dryer again or until this exhaust is cleaned out by a professional.  What a fire hazard.  We feel like Sunshine Home Inspection saved a life.
