What is a Crawl Space Vapor Barrier?

A crawl space vapor barrier is a robust plastic sheet covering crawl spaces’ walls and floors.

This barrier controls excessive moisture and defends against water vapor permeation in crawl spaces. Vapor barriers stop mold growth, wood rot, and pest infestations.

Matvey Foundation Repair uses the CrawlSeal™ system, a strong, multi-layered liner that protects your home structure from moisture damage. This barrier is an all-encompassing solution for preserving home health.

Signs You Need a Crawl Space Vapor Barrier Installation

Identifying a problem is the first step towards fixing it. Both inside and outside your crawl space, there are signs. Neglecting these problems will lead to expensive repairs down the line.

Watch out for these typical signs:

Is a Crawl Space Vapor Barrier Installation Necessary?

Moreover, working in crawl spaces involves safety hazards, so it’s best to leave it to trained professionals equipped with the proper safety gear.

Yes, a vapor barrier is vital for crawl spaces, especially if there are signs of dampness or humidity. Failure to install one can lead to moisture infiltration and structural damage.

What Are the Benefits of a Crawl Space Vapor Barrier?

Using a vapor barrier for moisture control brings these benefits:

  • Better Indoor Air Quality: The CrawlSeal™ barrier stops moisture from entering, reducing mold and improving your home’s air quality.
  • Stronger Structural Integrity: A dry crawl space provides a more stable foundation.
  • Increased Energy Efficiency: A well-insulated, sealed, and dry crawl space boosts energy savings.

Our CrawlSeal™ liner is strong, protects against microbes, and is resistant to punctures, keeping your crawl space clean, dry, and healthy.
