A dry crawl space is essential for preserving the structural integrity of your Canadian home. If you notice water or humidity in this part of your house, you should take action immediately. Otherwise, you could risk your property’s foundation, resulting in complicated and expensive repairs.

Other problems associated with wet and humid crawl spaces include mold and mildew, which can impact your family’s health.

A reliable vapor barrier is at the heart of any good crawl space repair solution. Our AquaStop™ CrawlSeal™ system controls excessive moisture, creating a drier and safer environment. 

What Is a Vapor Barrier for Your Crawl Space?

A vapor barrier is a heavy-duty plastic sheet that attaches to the walls and floor in your crawl space. It shields against excessive moisture and water vapor, circulating high-quality air throughout this area.

By keeping moisture at bay, vapor barriers also prevent mold, fungi, and pests from infiltrating your crawl space. Without water, these organisms can’t survive. That means you can protect your family’s health and home’s foundation. 

Not all vapor barriers are created equal, and you need one with a sturdy and layered design that provides long-lasting protection. CrawlSeal™ offers just that, making it great for maintaining a moisture-free property. This barrier is also antimicrobial and puncture-resistant! 

For more comprehensive crawl space repair, we recommend combining a vapor barrier with other solutions, such as dehumidifiers and crawl space jacks.

Is a Crawl Space Vapor Barrier Essential? 

We believe a vapor barrier is necessary if your crawl space has dampness or humidity. Delaying action could lead to more moisture entering this area, resulting in additional damage and costly repairs.

Sure, you could install a vapor barrier yourself, perhaps one from a local hardware store. However, off-the-shelf products might not fit properly or provide the right amount of protection.

Plus, your crawl space might already contain mold spores and other pathogens that cause allergies or illness. Trained professionals with the right gear can safely install a vapor barrier for you!
