Here’s How to Protect Your Home with a Sealed Crawl Space

Warmer weather is right around the corner in Southeastern North Carolina, which means so are longer days and weekends spent at the beach. But you don’t have to live here long to know that also means the humidity will be in full force. But did you know humidity does more than just make you feel sticky and uncomfortable? In fact, high humidity levels can have damaging effects on your home’s foundation and air quality. That’s why it’s important to make sure your crawl space is properly sealed.

In the past, foundation vents were used to control humidity. The vents would open in warm months and close in colder months. However, this method has been found to be ineffective and can lead to the very issue you’re trying to avoid – moisture accumulation.


The Dangers of High Humidity Levels

The first question you may be asking is “what is considered a high humidity level?”. For the answer to this question, we look at the relative humidity level, which is the amount of water the air can hold. For example, if the humidity level is 100% then the air is saturated, and you’ll see condensation. However, the relative humidity level only needs to reach about 70% for mold to thrive. With a quick test, we can measure the humidity level in your crawl space to determine what protective steps to need to be taken.

You see high humidity levels in your crawl space go beyond feeling damp and uncomfortable inside your home. It can cause detrimental problems like wood rot, mold, and unwanted pests. These issues are not only inconvenient but also lead to costly future repairs and can impact the air quality inside your home.
