Once praised for their ventilation benefits, open crawl space vents are now considered outdated and can be replaced with more effective, safer alternatives.

Understanding Open Crawl Space Vents 

Initially intended for moisture control, open crawl space vents, rooted in outdated building practices, are now considered problematic. They can cause: 

These issues threaten your home’s structural integrity and health. If you observe these signs or have open crawl space vents on your property, Ohio Basement Systems can help. 

The History of Open Crawl Space Vents 

Until the mid-20th century, the prevailing wisdom was that installing vents in crawl spaces was beneficial, as it was thought to improve air circulation and reduce dampness and moisture. 

However, this assumption has been proven incorrect. Current understanding indicates that crawl space vents often worsen these problems instead of solving them. 

Studies from the 1990s have shown that these vents allow dampness and moisture to enter, negatively impacting a home’s energy efficiency and making it difficult to keep indoor temperatures consistent. 

As a result, the installation of crawl space vents has greatly decreased in recent decades, with building codes and regulations adapting to favor vent sealing and crawl space encapsulation. 

Today, it’s standard practice in crawl space enhancement to cover these vents. Sealing them is now recognized as a superior method, fostering a healthier crawl space environment, especially when accompanied by artificial air circulation methods.  

Can You Fix Open Crawl Space Vents?  

Yes, open crawl space vents can be effectively managed, but merely covering them is not enough. A holistic approach to your home is required for enduring outcomes. 

Incorporating the sealing of crawl space vents into a complete encapsulation strategy can convert a moist, unhealthy crawl space into a clean, dry, and well-conditioned area. 

With more than 20 years of experience, the professionals at Ohio Basement Systems are adept at resolving crawl space moisture issues and providing lasting solutions. We have the expertise to identify the fundamental causes of problems in your home and implement customized repairs tailored to your needs.
