i recently did an inspection on a home that had been added to, the crawl space under the 4 bedrooms are separated into 2 different crawl spaces including different access panels, there is no water lines or waste/drain lines in the area, all electric runs through attic. my problem is i noticed alot of condensation on the subfloor, i mean water drops. this house is a foreclosed house that has been empty about 9 months, all i can figure is there is no vapor barrier and the vents were all closed. any idea of anything else?
