exclaimation-pointWhat Causes High Indoor Humidity?

High indoor humidity is caused by crawl space humidity. Crawl space humidity is caused by a vented crawl space, dirt crawl space and wet weather.


Open Crawl Space Vents

Open crawl space let in outside moisture. When you vent your crawl space on a humid day, it pulls in moisture. And when you vent your crawl space on a hot day, humidity forms. Crawl space humidity forms when the warm outside air combines with the cool crawl space air.

Dirt Crawl Space

Dirt likes to hold onto moisture. As the dirt floor in your crawl space dries, the moisture is released into the air, creating crawl space humidity.

Wet Weather

Rain is great for your garden but not for your crawl space. Moisture seeps into an unsealed crawl space through loose access doors, vents and foundation cracks.
Why Should I Fix My Crawl Space?

Why Should I Fix My High Indoor Humidity?

While high indoor humidity can seem like nothing more than a discomfort, it creates problems for your home, wallet and health.

All of the air in your home is circulated through your crawl space. Your crawl space is, on average, much cooler than the outside air and the air in your home. As you know, warm air rises – this is why your attic and second story are always warmer than the rest of your home.

As the warm air rises it creates a vacuum, pulling up the cooler air from your crawl space. This is also known as the Stack Effect. So, that wet air in your crawl space is being cycled through the living areas in your home. As the crawl space humidity rises, it creates high indoor humidity and other problems like wood rot, mold, bug infestations and high electric bills.
