Signs You Need a Crawl Space Vapor Barrier 

Knowing when to invest in a crawl space vapor barrier is crucial. Here are signs that it’s time: 

These issues indicate the presence of excessive moisture, drainage problems, and other damage. Vigilance is key to maintaining a safe and healthy home, and it’s crucial to consult with crawl space professionals as soon as you notice a problem. 

Is a Crawl Space Vapor Barrier Necessary? 

Yes, adding a vapor barrier is necessary if your crawl space has signs of dampness or humidity. Without a vapor barrier, you allow moisture to freely enter your crawl space, which inevitably causes damage and increases repair costs over time.  

Acting promptly with Ohio Basement Authority’s encapsulation solutions protects your home and forms a crucial part of our whole-home health approach. 

We do not recommend DIY installations, as big-box store liners are thin and fail to adequately protect the crawl space. This leads to additional damage and expensive future repairs. Your crawl space may also contain health and safety hazards, so it’s best to entrust inspections and repairs to experienced professionals with the right tools, training, and safety gear. 

What Are the Benefits of a Crawl Space Vapor Barrier? 

Stopping moisture at its source with the help of a vapor barrier provides many benefits, including: 

  • Improved Air Quality: Our CrawlSeal™ barrier blocks moisture, reducing mold and mildew and enhancing your home’s air quality. 
  • Enhanced Structural Integrity: By keeping the crawl space dry, we protect the structural integrity of your home from the ground up. 
  • Energy Efficiency: A dry crawl space is an insulated crawl space, meaning better energy efficiency and lower bills. 
  • Helps Deter Pests: Pests like termites are drawn to damp crawl spaces. A vapor barrier and other moisture management solutions create a less attractive environment for pests and make it difficult for them to get inside. 

Our proprietary CrawlSeal™ liner was expertly designed to be puncture-resistant and antimicrobial. Paired with our encapsulation process, it keeps your crawl space clean, dry, and breathable year after year.
