My clients had already purchased the home, (without an inspection prior to purchase....don't ask me why) They wanted an inspection for their homeowners insurance so I was contacted. Kind of backwards if you ask me. Yeah I noted that all the junk down there should be removed including the carpet, home owner fixed the duct work on the spot, minus taping the connection. I mentioned that a vapor barrier should be put down, and it seemed that the crawlspace vents were too small. So I mentioned that they should look into adding more ventilation. I hope this doesn't come back to bite them in the butt. (no pre-purchase inspection)
