Unfinished Areas in Basement
During the first year, you may experience some minor dampness in the unfinished areas of your basement resulting from condensation. Condensation is caused by warm, moist air entering the space or by the drying out of the materials from which the house was constructed.
Generally speaking, this type of condensation dampness in the basement is only likely to occur during the first year of occupancy.
If you are using this part of your basement as a storage area, make sure your possessions are away from the walls and up off the floor.
