What is a Crawl Space Vapor Barrier?

A crawl space vapor barrier is a plastic sheet that seals crawl space walls and exposed earth floors.

Vapor barriers seal your crawl space against moisture which puts a hard stop to mold, wood rot, and pest invasions.

By choosing AFS, you’ll get our CrawlSeal™—our custom, multi-layered barrier—to protect your home from moisture’s harmful impact.

Is Crawl Space Vapor Barrier Installation Necessary?

Yes, installing a vapor barrier is necessary if your crawl space has moisture or humidity. Without this barrier, moisture freely enters the area, leading to damage and escalating repair costs over time.

We advise against DIY installations, as vapor barriers from general retailers are often too thin and don’t adequately protect crawl spaces.

This can result in further damage and costly repairs down the line. Additionally, crawl spaces present health and safety risks without proper equipment. It’s safer to rely on professionals equipped with the necessary tools, training, and safety gear.

What Are the Benefits of Installing a Crawl Space Vapor Barrier?

Installing a vapor barrier to prevent moisture at its source provides several advantages:

Enhanced Air Quality: Our CrawlSeal™ barrier prevents moisture, reduces musty odors, and improves indoor air quality.
Stronger Structural Integrity: A dry crawl space maintains the structural strength of your home.
Energy Savings: A moisture-free crawl space means better insulation, increased energy efficiency, and reduced utility bills.
Pest Prevention: Damp crawl spaces attract pests like termites. A vapor barrier and other moisture control methods create an environment that’s less appealing to pests and hinders their entry.

Our specially designed CrawlSeal™ liner is puncture-resistant and includes antimicrobial features. Combined with our encapsulation process, it ensures that your crawl space remains clean, dry, and well-ventilated long term.
