FAQ:

Q: Should vents on crawl space be open in winter?

A: To prevent this, make sure there is plenty of ventilation in the crawl space. Ideally, the vents in the crawl space should be open year round because condensation problems can occur in the winter as well as the summer. In the winter, some people are reluctant to leave the vents open because of possible heat loss through the floor.

Q: Should you vent your crawl space?

A: No, you do not need vents if you encapsulate your crawl space. The bottom line is if you install the high-performance vapor retarders correctly, you can forget about your vents. I don’t care if you keep them open or closed, it will make little difference.

Q: Should I Close my crawl space vents during winter?

A: You should always close the crawl space vents in your home before winter sets in. You want to keep out the cold winter air from reaching your pipes. The other advantage to closing your crawl space vents throughout the winter is it helps keep the wet air out during rainy weather.

Q: Does your crawl space need vents?

A: If, however, you cover the bare ground in your crawl space with an approved vapor barrier material, you only need 1 square foot of vent for every 1,500 square feet of space. The code also requires that there be one ventilated opening near each corner of the building. This is necessary to ensure a good cross-flow of air.
