What Should the Humidity Be in a Crawl Space?

Crawl space waterproofing

Crawl space humidity should range between 45% to 55%. A crawl space with high humidity creates an ideal environment for mold, pests, and viruses. It can also cause issues with your home’s foundation, such as wood rot or condensation leading to standing water.

You can measure crawl space humidity levels using a hygrometer (aka. humidity tool), which you can buy online or at a local hardware store.

The solution to reducing humidity in a crawl space can include:

A) Encapsulating the space

B) Adding a dehumidifier
