Dampness in your crawlspace is a common problem and can cause significant problems for you, not only with the structure of your home but also to have an effect on our health as well.
Without a proper barrier, your crawlspace carries humid air that condenses and settles on the pipes, walls, and even the subflooring. This moisture provides the ideal environment for fungus, mildew, and pests.
A moisture barrier prevents water from seeping into the air beneath your home. This helps prevent fungus and mildew growth in these moist, dark spaces that can cause respiratory problems.
Moisture barriers are composed of either foil or plastic material which stops this moisture from penetrating through any cracks.
