Is it OK to seal off crawl space vents for the winter?
Just wondering if it's OK to seal off crawl space vents for the winter? Or will this lead to dryrot and moisture problems? I'm just trying to find ways to seal my house up a little better and conserve energy.
There used to be all kinds of moisture problems in my crawl space but I installed the vents and put down plastic on the ground and made sure the down spouts were running away from the house. Now it's nice and dry down there but in winter the vents let in a lot of cold air. (The vents are self closing, but the flaps are just thin aluminum.)
