  • Are my Gutters Causing Water to Enter my Crawl Space?

    If your gutter is not properly draining away from your house, this can lead to standing water around your house and soil erosion around your foundation. If you think about the square footage of your roof divided by the number of downspouts in your gutter systems, that’s a lot of water building up around your foundation. Depending on the house, properly draining gutter downspouts away from your home can help solve a lot of water issues in your crawl space or basement.

  • What is the Difference Between a Vapor Barrier and Encapsulation?

    A moisture or vapor barrier (also called crawl space plastic) is the plastic sheeting that is rolled out and sealed to your crawl space walls. It prevents moisture and humid air from entering your home via the crawl space that would have come from the ground beneath your home.


    Encapsulation is the full process of sealing the walls, floor, posts and piers of your crawl space which INCLUDES installing a vapor barrier. It is an important process that keeps moisture and mold out of your crawl space and prevents structural damage and health issues that may arise from problems underneath your home. It also includes cleaning out any debris in your crawl space, making sure your crawl space is properly insulated around the ceiling and walls, and installing a dehumidifier to regulate humidity levels in your newly-sealed crawl space.
