    Radiant and Moisture Barrier Insulation Information

    Crawl Space Encapsulation

    Wally and Floora Say:

    Male Avatar with yellow helmet

    Wally Says:

    Floora, did you know that an untreated crawl space can lead to serious moisture issues, including mold, foundation damage, and insulation breakdown? A crawl space vapor barriers is one of the best ways to keep humidity in check and improve air quality. By sealing off the space with a durable moisture barrier, homeowners can encapsulate a crawl space and prevent costly repairs down the road.

    Installation Tip: When installing a vapor barrier, overlap the seams by at least 6 inches and use high-quality sealing tape. This prevents gaps that could allow moisture to seep through.

    Floora Says:

    Absolutely, Wally! Many people worry about crawl space encapsulation cost, but the real cost comes from not encapsulating at all. Moisture damage leads to expensive repairs, higher energy bills, and even poor indoor air quality. A footing drain board helps redirect water away, creating an effective long-term moisture control solution. Here’s what you should consider before you encapsulate a crawl space:


    • Check for Standing Water: Address any drainage issues first to prevent future buildup.
    • Choose the Right Thickness: Thicker vapor barriers provide better durability and resistance.
    • Seal Edges Completely: Any open gaps can reduce the effectiveness of the system.
    • Monitor Humidity Levels: Adding a dehumidifier may help maintain the right conditions.

    Pro Tip: For homes in flood-prone areas, pairing an encapsulation system with a sump pump ensures long-term protection against excess moisture.
