Open Crawl Space Vents

Initially thought to keep air flowing in your crawl space, open vents are now known to actually cause moisture issues below your home. They can be substituted with more efficient, safer alternatives. 

With our extensive experience and dedication to long-term solutions, AFS tackles the issues caused by open vents effectively. Our team converts your crawl space into a secure, moisture-free, and energy-efficient area. 

This page will walk you through the history of crawl space vents, the difficulties they present, and the advantages of professional, tailored repairs for your home. 

What Are Open Crawl Space Vents? 

Originally intended to meet building regulations and combat moisture, open crawl space vents are based on outdated construction norms. Yet, these vents often lead to more issues than they resolve, including: 

These problems can significantly jeopardize your home’s structural soundness and your health. If you observe these symptoms or spot open vents on your house, it’s crucial to contact crawl space professionals like AFS immediately. 

Why Your Home Has Open Crawl Space Vents 

Until the mid-20th century, it was a common belief that installing vents in crawl spaces would improve air flow and reduce moisture and dampness. More recently, this has been proven incorrect.  

Studies in the 1990s showed that these vents allow moisture and dampness to enter and negatively affect a home’s energy efficiency, making consistent indoor temperatures hard to maintain. 

As a result, the use of crawl space vents has decreased significantly in recent decades. Building codes have evolved to include vent sealing and crawl space encapsulation. 

Today, sealing these vents is a standard practice after a thorough crawl space inspection. Closed vents are recognized as a more effective way to create a dry environment in the crawl space. 

Can You Fix Open Crawl Space Vents? 

Indeed, open crawl space vents can be effectively remedied. However, trying to simply cover them with DIY methods won’t cut it; a comprehensive home solution is essential for enduring results. 

Addressing this issue requires a holistic approach, considering every aspect of your crawl space. Sealing crawl space vents as part of a complete encapsulation system can turn your damp, unhealthy crawl space into a clean, dry, conditioned area.
