I bought a dehumidifier for basement after realizing RHT was at 83% down there. It is now at a comfortable 55%. I did noticed some mold on the joists but haven't had a water problem for years. My question is: Would this dehumifier prevent the mold from getting worse or growing new mold? Keep in mind its behind the baseboard molding. Does the dehumidifier actually dry the air behind the baseboard and walls?
