Ever had your basement flood?

When I was in college, I briefly worked for ServePro cleaning up this exact stuff. It's been awhile but it seems like you've done just about everything you can. The key is to keep moisture out of the pad to prevent rot and smell.

If you can lift up the carpet and get to the pad, run the fans blowing directly on the pad. That's where a lot of the problems will end up - the carpet really isn't much of a problem.
