Since I have put down (on the dirt) 6 mil vapor barrier taped up the side of the cinder block walls (almost to the sill), and plugged and foamed all the vents, my moisture readings dropped from 90+ percent to 35-45 depending on the weather. It is currently winter time and the avg temp is in the 50's down there all the time (10-20 degrees outside). What if any pitfalls do I face when the warmer/wetter weather comes if I leave it sealed up? We will have central air but the avg temp in the house will remain around mid 70's. This is a manufactured home on a cinderblock foundation. Any advice would be greatly appreciated. Thanks so much.
