Live in a 1950's house in Kansas. The basement walls are made of poured concrete with half of the wall above ground level in the back of the house. The interior side of this wall has condensation only on the part of the wall that is above ground. The basement is finished and heated. There was mold growing where the condensation is. I killed the mold but I want to stop the condensation so that the mold issue does not come back. This has been a particularly cold winter which I think has contributed to this problem. Any ideas as to the solution to this problem?
