Should I Cover My Crawl Space Vents?

Crawl space vents were initially installed into properties across North Carolina between the 1950s and 1990s because they were thought to reduce the risk of dampness and humidity by increasing airflow. Of course, they were found to increase airflow in the home, but this turned out to be a bad thing upon further investigation. Studies found that crawl space vents were actually likely to cause dampness and increase humidity levels. As such, it became common practice to cover them.

Of course, there is not much that simply covering your crawl space vents will do if they have been open for a long period of time. If you simply cover the vents, then you could potentially trap moisture or pests into your Charlotte home. However, with that said, it is definitely a good idea to invest in water and weather-proof crawl space vent covers as a part of more widespread waterproofing and encapsulation methods.

The benefits of crawl space vent covers are many, however. As well as making it more difficult for pests and water to enter your home, they also can play a part in managing the more subtle aspects of moisture management. By stopping the stack effect from impacting your home, crawl space vent covers will also prevent condensation and have an impact on levels of relative humidity in your crawl space and wider property.
