From the TOH ****** EDITORS Inbox:
For some time now a spot in my carpet gets damp and stays damp for long periods of time. I have explored under the spot from the crawl space and find no sign of moisture, I have drilled through the floor and located the center of the spot, cut the vapor barrier and put my hand thru and the top of the insulation is dry. Have you ever had a similar problem? Any suggestions? I am getting ready to replace the carpet of perhaps put a wood or laminate floor in that area and more.
Thanks for your help.
