Moisture Barriers

When compared to property-damaging pests, such as carpenter ants and termites, a damp crawlspace may not seem like a major issue for your home. However, there’s a wide range of fungi just waiting to feed on your crawlspace’s moisture and infest your home. In fact, fungi can cause more damage to your home than pests.

In addition to damaging your home, fungi fed by your humid crawlspace can cause serious health issues to you and your family, such as asthma and pneumonia. Thankfully, there’s a way you can protect your home and family: a moisture barrier from U.S. Pest Protection.Termite Protection Employee from U.S. Pest holding a clipboard - US Pest Protection Nashville TN

What is a moisture barrier?

A moisture barrier is a material that prevents typically damp areas in your home, such as your crawlspace or basement, from forming moisture that may draw pests or produce fungi. With U.S. Pest Protection and U.S. Crawlspace’s moisture barrier services, we’ll shield your crawlspace from moisture and fungi with the following steps:

  • 100% ground coverage
  • Reinforced 10-millimeter polyethylene vapor barrier
  • Liquid wood treatment
  • Overlapping barriers to ensure full coverage

If you have questions or concerns about installing a moisture barrier in your home’s crawlspace, contact U.S. Pest. Our experts will be happy to provide you with the answers and resources that you need.

Our Moisture Treatment Services

Ventilation Systems

To ventilate your crawlspace properly, we’ll install powered foundation vents on one side of the house and non-powered vents on the other. This will create a steady flow of air through your crawlspace, which will protect your home from mold, rot, and insect problems.


Half the air in your home rises from your crawlspace, which makes it critical to ensure these drafts don’t produce mold and mildew. We perform thorough encapsulation services to ensure the internal integrity of your crawlspace. We’ll clean your crawlspace, seal any cracks, and cover your walls and floor with a six-millimeter thick sheeting.

Once your crawlspace is completely sealed, we’ll install a dehumidifier to remove moisture completely and keep it free of fungi and pests.

Termite and Fungus Treatment

Keeping moisture out of your crawlspace is only half the battle. If moisture seeps into your home’s wood, it can create a wide range of issues, such as wood-destroying fungi and termites. During our moisture inspection, we’ll check for signs of termites and provide effective pest solutions for prevention and control.

In addition to damaging more homes than fires and termites combined, wood-decaying fungi can cause serious health problems. If we find wood-decaying fungi during our free inspection, we can help you form an effective pest solution. We use Moldcare and Boracare to preserve the wood in your home.
