Crawl Space Venting (Question)

Hey Al,

I have a question about the winter checklist article. One of the suggestions was to close the vents to the crawl space (especially near plumbing).

I have heard you should close these vents unless it is going to be below freezing for a long period of time. I was under the assumption that venting under a foundation and an attic was just as important in the winter as it is in the summer.
Am I wrong?

Please let me know your thoughts on this.

Thanks J.T.


I will post the answer tomorrow.
