At what humidity does mold grow in crawl space?
Increasing the relative humidity of the air in the crawl space approximately 26% (from 51% outside to 76% in the crawl space). At 60% RH, mold begins to grow. Coupled with warm temperatures and organic material, mold now has the perfect environment to thrive in the crawl space.
What is the best way to ventilate a crawl space?
The following are more options for venting the crawl space:
- Transfer a small supply of heated air from the HVAC system into the crawl space.
- Use an exhaust fan to move air from the crawl space to the outside.
- Install an air intake or dehumidifier system.
When to use dehumidifier in crawl space?
Crawl space encapsulation is most effective when you seal the space completely. As soon as you’ve encapsulated the space, you can use a dehumidifier to help regulate the moisture levels in the area. How Does Crawl Space Encapsulation Differ From Insulation? Many homeowners confuse between crawl space encapsulation and crawl space insulation.

Crawl space encapsulation is most effective when you seal the space completely.
Are there any problems with an encapsulation addition?
