How Open Vents Damage Your Crawl Space

Open crawl space vents allow moisture to enter this part of your home, potentially causing mold, dampness, and pest infestations. If ignored, moisture might eventually harm your structural components, resulting in costly repairs.

Matvey Foundation Repair tackles these challenges with the latest crawl space encapsulation solutions. Our team can transform this area into a drier, safer, and more energy-efficient environment.

What Are Open Crawl Space Vents?

In the 1950s and 1960s, home builders added open vents to crawl spaces to meet construction codes. The goal of adding vents was to manage the flow of moisture in and out of the crawl space and to stop it from building up and damaging homes. However, these fixtures often cause more problems than they prevent.

If you have open crawl space vents, you might experience the following:

These issues can threaten your structural elements and your family’s health. We recommend contacting a crawl space encapsulation expert like Matvey Foundation Repair as soon as possible.

Why Your Home Has Open Crawl Space Vents

Incorporating vents into crawl spaces was standard practice until the end of the 1990s because builders believed they improved air quality and reduced moisture.

The use of crawl space vents has declined in recent decades, and building regulations have evolved to include vent sealing and crawl space encapsulation.

Sealing old vents can promote a healthier crawl space environment, especially when combined with artificial air circulation.
