Crawl Space Encapsulation

Good defense is the best offense when it comes to avoiding crawl space problems, and encapsulation provides the best protection against moisture in your crawl space.

Have you been dealing with musty smells in your home? Maybe you’ve noticed sagging floors or mold growth in certain areas of your home. All of these are crawl space problem signs that indicate there is too much moisture below your home. Thankfully, Basement Authority of West Virginia has the tools needed to minimize moisture damage with crawl space encapsulation – a barrier between your crawl space and water.

How Crawl Space Encapsulation Works

Encapsulation involves a combination of tools working together to mitigate the amount of moisture in your crawl space. Here’s what you can expect during the installation process. 

  1. First, our team will install internal drainage systems for your crawl space. These include a crawl space drain and a sump pump, both of which monitor moisture levels below your home and move water away from the crawl space. Without drainage, groundwater would still be able to pool under your home. 
  2. Next, our team will install a vapor barrier, which covers the entirety of your crawl space walls and floor. This 20-mil thick vapor barrier acts as a strong shield against both water vapor and water from rain or runoff. Along with the vapor barrier, our team will also install vent covers to make it even harder for humidity to enter your crawl space.
  3. Last, we’ll install a dehumidifier in your crawl space to ensure it stays dry year-round. While the vapor barrier can do most of the heavy lifting, West Virginia gets its share of muggy days during the summer, and it always helps to have a dehumidifier below your home. With all of these tools working together, your crawl space stays dry year-round, even during the wettest months.

How Our Crawl Space Encapsulation Stands Out

  • Energy Efficiency: Encapsulation helps lower your utility bills and create an energy-efficient home. Normally, moisture in your crawl space rises into your home and causes your HVAC system to work on overdrive. Encapsulation stops this process from happening and saves you money. 
  • Mold Can’t Grow: Wet crawl spaces are the perfect breeding ground for mold, but encapsulation takes away the moisture mold spores need to grow, flourish, and spread throughout your home. This creates a healthier crawl space and home overall. 
  • Discourages Pests: Without encapsulation, pests are drawn to your humid crawl space, as it offers them a place to rest. Unfortunately, animals and bugs can spread disease or leave waste below your home. Encapsulation makes this much less likely to happen. 

Signs Your Home Will Benefit from Encapsulation

Mold and Mildew

Mold growth is extremely prevalent in unprotected crawl spaces. Without encapsulation, mold can run rampant below your home. Eventually, it might even spread into your home. If you’ve noticed mold growing anywhere in your home, you may benefit from crawl space encapsulation.

Wood Rot

Another symptom of moisture below your home is wood rot. As water permeates the wooden supports below your home, they can break down over time. Wood rot can lead to other issues in your home like sagging floors or wall cracks, but encapsulation prevents this from happening.

Musty Odors

Musty odors might arise for any number of reasons below your home. These include pests leaving waste, mold growth, or decaying wood. If you’re noticing musty smells every time you walk into your home, encapsulation can definitely help.


No. Vapor barriers require specialized tools and training to install properly. While you can purchase vapor barriers at a hardware store, these products are often much less effective than professional vapor barriers. Plus, any misstep during a DIY installation can end up costing you more time and money, as water will still penetrate your crawl space.

Yes. Mold can exacerbate allergies and cause health problems, specifically to your respiratory system. When left unchecked, mold spores can spread all throughout your home and make the air unhealthy. Don’t let an unprotected crawl space cause health problems to get worse and force you to spend more money on medical bills.

Yes and no. Encapsulation can certainly discourage pests from entering your crawl space and make it more difficult for them to do so. Not only does the vapor barrier serve as a physical protection from critters, but it also lowers humidity levels which makes your crawl space less attractive to most pests. However, encapsulation doesn’t guarantee that pests will stop trying to get into your home. For serious pest problems, make sure to contact a professional pest control service.
