How Can I Keep Moisture Out of a Crawlspace?

Crawl spaces have their advantages — just make sure you keep moisture out of them.

Danny and Joe welcome callers’ questions each week on the Today’s Homeowner Radio Show.

Here’s a question from our Oct. 5 broadcast:

Robert in Virginia says, “What is your opinion of crawl space foundations? Avoid them? Encapsulate? Other? They are popular in Virginia Beach, but I am skeptical.

I have lived in 46 places in 26 cities in 15 states (Maine to Florida to New Orleans to Denver) and have never lived with one. They seem to be an invitation to bugs, wood rot, mold and worse. [FYI, I am looking for a new home … and am concerned about buying a house with a crawl space and why would someone build it?]”

We tell Robert weighted-down plastic on the ground will keep moisture from rising up. For ventilation, Robert needs at least one square foot by every 150 square feet of living area to allow the air to flow through.
