What Are Open Crawl Space Vents? 

Originally thought to help with circulation, open crawl space vents actually cause a number of issues for your home and crawl space. Here’s what you’re likely to run into: 

These issues can seriously compromise the structural integrity of your home and your health. If you notice these signs or discover open vents in your home, it’s vital to get in touch with crawl space experts like Alpha Foundations immediately. 

Why Your Home Has Open Crawl Space Vents 

Until the mid-20th century, the prevailing thought was that vents in crawl spaces would aid in air circulation and moisture reduction.  However, research in the 1990s revealed that these vents actually cause more harm than good by allowing humid air to get into the crawl space.  

This impacts a home’s energy efficiency and makes it difficult to maintain a consistent indoor temperature. Consequently, the use of crawl space vents has significantly declined in recent years.  

Building regulations now recommend sealing crawl space vents and installing crawl space encapsulation.  As a result, sealing these vents is a common practice following a detailed crawl space inspection.  

Can You Fix Open Crawl Space Vents? 

Yes, open crawl space vents can be successfully addressed. However, makeshift DIY solutions are insufficient; a comprehensive approach is necessary for lasting results. 

Tackling this issue requires a comprehensive strategy, taking into account every aspect of your crawl space. Sealing crawl space vents as part of an overall encapsulation process can transform your damp, unhealthy crawl space into a clean, dry, and well-conditioned space.
