Hello, I need help! I have a small one story single family home. We removed the old/damp insulation and I need to know if I should close off the vents and put a dehumidifier in the crawl space? I do have a vapor barrier on the stone ground, but there still is moisture and some signs of mold! We did put a sump pump in there last summer. What should I do, this property is in Annapolis MD.
Thanks!
Lynn
