I live in the southeast.My house has a crawlspace with foundation vents. The insulation under the floor is damp from condensation and it was recommended that I remove it. I was told that I did not need to replace it and needed more ventilation. But I keep reading conflicting info. Do not vent, add more vent, add fans, add dehumidifiers, close vents in summer, close vents in winter only. There should be one right answer. Help!
