Open Crawl Space Vents

If you have a vented dirt crawl space below your home, you could be dealing with unhealthy conditions you may not know about.


Venting your crawl space lets moisture into your home. When moisture enters your crawl space it creates problems. Crawl space humidity creates the perfect breeding ground for mold, mildew, and other problems. And as the humidity rises, it damages your home resulting in wet crawl space insulation, wood rot, and high electric bills.

Frequently Asked Questions

There’s been a lot of debate about the value of venting your crawl space. The original idea behind crawl space venting was that the air flow would keep your home dry. However, we now know that this isn’t true.E

Open Crawl Space Vents & Moisture

Crawl space vents let moisture into your crawl space, and crawl space moisture creates problems throughout the rest of your home.E

Stack Effect

The crawl space moisture is carried through your home with the air cycle, which is also called the “Stack Effect”. The warm air in your home rises, creating suction that pulls the cool air in your crawl space up into the rest of your home. So, the humid air in your crawl space is being cycled through your home.

As the crawl space humidity rises it creates a variety of problems, including wet crawl space insulationwood rot, and is the perfect environment for mold and dust mites.

If the crawl space vents aren’t air tight then you’re not solving the problem. Closing the crawl space vents will not solve the humidity created by other sources. If the crawl space humidity is left alone, then it’ll create other problems like rotted floor joists, mold growth and a musty crawl space.
