Where should you start?
Water on the ground after storms or soft wood points to the repair page first, since both get fixed before anything is sealed. Plastic that is ripped, bunched or absent sends you to the vapor barrier page. When the plastic looks fine but the house still smells damp, read the dehumidifier page. If you are not sure what any of it means, the warning signs guide matches what you see upstairs to what is probably happening below.
