Protect Your Crawl Space from Excessive Moisture
Vapor barriers are a must-have in many homes throughout Virginia and the Southeastern United States. With our humid climate comes condensation, and lots of it.

What Is a Vapor Barrier?
A vapor barrier is a heavy plastic liner that prevents moisture from moving through building materials, which safeguards buildings from mold, wood rot, insulation damage, and other issues.
Often, we install vapor barriers in crawl spaces, laying them directly over the soil and sealing them to walls and piers to block ground moisture. We can also install them in other locations, such as on the exterior side of foundation walls. Doing so provides the same kind of moisture protection.
We focus on installation practices that keep the plastic tight to the soil and neatly trimmed around supports. When the barrier lies flat, it reduces tripping hazards for anyone who needs to enter the space later and creates a cleaner surface for inspections and service visits. Over time, that neat installation can make it easier to spot changes in your crawl space and address them before they grow.
When Should You Install a Vapor Barrier?
Property owners often ask when it makes sense to install a vapor barrier. While every property is different, several common situations point to the need for better crawl space moisture control.
We may recommend a vapor barrier in situations such as these:
- Crawl space soil looks damp or muddy much of the year
- Floor joists or subfloor show signs of surface mold or fungal growth
- Insulation under the floor feels wet, heavy, or sagging
- You notice musty odors that seem to come from vents or floor registers
- Your property has a history of moisture issues or wood damage in the crawl space
- You plan to sell, refinance, or remodel and must address visible moisture concerns

The Benefits of Installing a Vapor Barrier
The primary benefit of installing a vapor barrier is protection. Once in place, your vapor barrier will limit the amount of ground moisture that can reach your subfloor, joists, and other structural components. This can prevent costly damage and give you peace of mind that your most important investment—your home—is protected.
Other benefits include:
- Help with mold & fungal growth – Lower moisture often means fewer conditions that support surface mold and fungal growth on wood and insulation.
- Improved crawl space conditions – A covered floor generally feels cleaner and brighter and is easier to access for future inspections or repairs.
- Support for pest control – Drier crawl spaces may be less attractive to certain pests that prefer damp areas, which works hand-in-hand with our pest and termite treatments.
- Added appeal for buyers – For property owners preparing to sell, a neat, lined crawl space can make a better impression during inspections and walk-throughs.
Our Vapor Barrier Installation Process
When you trust us to equip your home with a vapor barrier, we’ll follow this proven process:
- Moisture inspection – We check conditions in your crawl space or any other area of concern, looking for evidence of moisture problems. Our moisture inspections are free, so you can get answers without added pressure.
- Material recommendations – Based on what we see, we recommend either a 6mm or 12mm polyurethane vapor barrier and explain why that thickness makes sense for your property.
- Installation plan – We walk you through how we will place and secure the material, how long the work should take, and how it fits with any pest or termite services.
- Installation – We install the vapor barrier, working to deliver results that adhere to the highest standards of workmanship.
- Care tips after installation – We explain basic ways to keep your crawl space accessible for future inspections and services.
How Vapor Barriers Support Termite & Moisture Reports
In the Southeast, lenders and buyers are often attentive to moisture and termite problems, especially in crawl spaces. While each transaction is different, a clean, lined crawl space can make the process much more seamless.
We complete termite and moisture reports for home sales and refinancing. When we recommend or install a vapor barrier, we consider how the work may improve access, visibility, and general conditions for future inspections. This helps you prepare your property for appraisals and buyer walk-throughs, as well as assisting you with meeting lender requirements.
Vapor Barrier FAQs
Do All Homes Need a Crawl Space Vapor Barrier?
Not every home requires a vapor barrier, but many in humid regions benefit from one. Properties with damp soil, musty odors, visible mold, or sagging insulation under the floor often gain the most from added moisture control. During your inspection, we can review your crawl space and help you decide whether a vapor barrier makes sense for your specific situation.
How Long Does a Vapor Barrier Installation Usually Take?
Most residential vapor barrier installations take a short amount of time, though larger or more complex crawl spaces may require more. The condition of the crawl space, existing debris, and access points also affect timing. Before any work begins, we’ll explain how long we expect your project to take so you can plan around the visit.
What Thickness Vapor Barrier Do I Need?
Common options include 6mm and 12mm plastic, and the right choice depends on your crawl space conditions and goals. Lighter material may suit some properties, while heavier material offers more durability where traffic or service work occurs more often.
Will a Vapor Barrier Stop All Moisture Problems?
A vapor barrier is an important tool, but it does not address every type of moisture issue on its own. It controls ground moisture that reaches the air and framing in your crawl space. In some cases, you may also need grading improvements, drainage changes, or other moisture services, which we can discuss during your inspection.
Can You Install a Vapor Barrier Along with Pest or Termite Treatments?
Many customers choose to coordinate vapor barrier work with pest or termite services. Because we provide treatments for 170+ different pests and are Termidor®-certified for termite control, we can design a plan that considers both moisture and pest risks.

Since Termites live one to sixteen feet underneath the soil, we generally don't see them until it's too late. Termites live in colonies underneath the soil and travel to wood sources using a scent trail. It's recommended that you at least have an Annual Termite Inspection done on the home. Here at Landlock, we also can help you take the steps to preventing your home against Termites. Ask us today about our Termite Prevention Plans!

There's often many areas around the exterior parts of the home that act as a pest attractant or areas that are conducive to pests. These could include, but certainly aren't limited to vents, windows, gutters, eaves, or debris and landscaping around the home, etc. While applying the treatment around the home, our technicians will also thoroughly inspect the exterior of the home looking for any problematic areas that could be drawing in more pests, as well as keeping an eye out for anything that should be brought to your attention as the homeowner.
