I recently noticed some condensation around a basement window, was concerned about moisture considering I'm in a low lying area. I felt behind the finished wall and found insulation lying right next to the poured concrete wall. I think the insulation is causing a minimal amount of black mold starting. Should there be no insulation in there if my walls are pored concrete. Should I tear out all the drywall and and start new with sealing the wall and then put up new drywall with no insulation? Right now I don't think there's any kind of an air gap?
