CRAWL SPACE VENTS
recently had a presentation by a crawl space contractor---he stated that when they are called in to restore a wet crawl space and put a vapor barrier in they seal all crawl space vents--he said they all should be sealed and HI should recommend that
now i was always told that the juror was still out on this---open vents in summer--close in winter--what does everyone think--and what if crawl has heat/ac vent
