Consequently, should I seal my foundation vents?
Some homeowners seal off crawl space vents year-round in order to stop termites in the summer, heat loss in the winter, and moisture buildup that can lead to mold growth; others open and close the crawlspace vents with the season.
Beside above, should you close the vents under your house in the winter? To control the humidity, you open the crawl vents in the winter to allow the warm moist air to flow naturally to the cooler, drier outside environment. In the summer, you close the vents to keep the warm moist air outside and away from the much cooler, drier air in the crawl space.
