Crawl Space Vapor Barrier

At Indiana Foundation Service, we understand that dealing with crawl space moisture is more than just an inconvenience. It poses a significant threat to your home’s structure and your family’s health. 

That’s why we’re here to help as trusted experts in crawl space solutions. Our AquaStop™ CrawlSeal™ vapor barrier offers a definitive solution to these issues through our specialized crawl space encapsulation process. 

As the local authority in crawl space encapsulation, we provide a protective shield against moisture, ensuring the health and longevity of your home. 

What is a Crawl Space Vapor Barrier? 

A crawl space vapor barrier is a thick plastic liner that covers walls and exposed dirt floors in crawl spaces. Its purpose is to prevent water vapor from rising into the crawl space, addressing excessive moisture issues. You can protect against dampness, mold growth, wood rot, and pest infestation by installing a vapor barrier. 

At Indiana Foundation Service, we use CrawlSeal™, a robust and multi-layered liner, as part of our comprehensive approach. This barrier is highly effective in protecting your home’s structure from the damaging effects of moisture. By safeguarding your crawl space it contributes to the overall health of your home, offering a complete whole-home solution. 

Signs You Need a Crawl Space Vapor Barrier 

Signs it’s time for a crawl space vapor barrier: 

These issues indicate excessive moisture, drainage problems, and damage. Stay vigilant for a safe and healthy home. Consult with crawl space professionals when you notice a problem. 

Is a Crawl Space Vapor Barrier Necessary? 

Yes, it is necessary to add a vapor barrier if your crawl space shows signs of dampness or humidity. Without a vapor barrier, moisture can freely enter your crawl space, causing damage and increasing repair costs. 

DIY installations using thin liners from big-box stores are not recommended as they do not provide sufficient protection for the crawl space and can result in future damage and costly repairs. At Indiana Foundation Service, we offer encapsulation solutions that protect your home and are crucial for overall home health.
