One of the biggest benefits of a vapor barrier is moisture control. Even when the soil underneath a home doesn’t appear wet, moisture can continuously evaporate from the ground and enter the crawlspace. Over time, elevated moisture levels can contribute to fungal growth and deterioration of wooden structural components such as floor joists, beams, posts, and subflooring. A properly installed vapor barrier helps separate the home from this source of moisture.

A drier crawlspace can also make conditions less favorable for termites and other pests. Subterranean termites, wood-destroying organisms, and many other pests thrive in areas where moisture is present. While a vapor barrier is not a substitute for termite or pest treatment, reducing excess moisture is an important part of creating a healthier environment underneath the home and addressing conditions that may contribute to pest problems.

Vapor barriers can also help create a cleaner, more accessible crawlspace. Covering exposed soil reduces mud, dust, and direct contact with the ground, making future inspections and repairs easier. It can also help reduce musty crawlspace odors and protect insulation, plumbing, ductwork, and other components located beneath the home. For homeowners looking for even greater moisture protection, heavier vapor barriers and full crawlspace encapsulation systems may also be available. Or simply using a thicker barrier like a 20ML will be a great option.
