Best Encapsulation Material for Crawl Spaces

Like every homeowner who’s conscious about their crawl space, you may be thinking about sealing this area under your house.

This space is prone to moisture problems, so you might be wondering how you’ll keep it moisture-free and clean for years. 

Whether or not yours is vented, it really pays to encapsulate your crawl space.

Using a plastic crawl space system can help you stop some of the problems before they start affecting your home.

Is Plastic Encapsulation Effective?

Yes. Depending on your situation, you can choose to install a plastic vapor barrier only or add additional products to better protect your home.

Dehumidification can help bring down moisture to 50%, which is where it should be to avoid issues with condensation and mold.

During encapsulation, your contractor will:

  • Cover the entire floor and walls of the crawl space with a 20-mil plastic barrier.
  • Seal edges to the wall liner using tape.
  • Insulate walls, beams, and joists.

By the end of the process, the crawl space will be:

  • Separated from the dirt and outside air.
  • Kept dry.
  • More difficult for pests to infiltrate.

Where Can I Find Encapsulation Material?

While you can find encapsulation materials at big-box stores, these products often aren’t thick enough and can actually cause more harm than good by promoting mold growth.

To ensure effectiveness, use high-quality materials specifically designed for crawl space encapsulation.

For the best results, consult with professionals like Foundation Recovery Systems. Our 20-mil thick barrier is designed to withstand medium to heavy traffic without tearing or ripping.

With over 30 years of experience, we have developed this product to meet the diverse needs of homeowners across the region, ensuring complete sealing and lasting protection for your crawl space.

How Long Does Encapsulation Take?

The installation of crawl space encapsulation typically takes about a day to complete. However, the exact duration can vary based on the size of the crawl space and the severity of any existing damage. If additional structural work is needed, such as the installation of crawl space jacks, the job could take longer. Factors influencing the timeline include:

  • Crawl Space Size: Larger spaces may require more time.
  • Damage Severity: More extensive repairs can extend the installation period.
  • Structural Needs: Installing support jacks or other reinforcements adds to the project duration.

Foundation Recovery Systems ensures a thorough and efficient encapsulation process tailored to your home’s specific needs.

How Much Will I Spend on Encapsulation?

Cost is a significant factor when considering crawl space encapsulation. Generally, you can expect to spend between $5,000 and $15,000.

The final price depends on several factors:

  • Condition of the Crawl Space: More extensive damage requires more materials and labor.
  • Size of the Crawl Space: Larger spaces require more materials and time.
  • Additional Repairs: Costs can increase if other repairs, such as sealing and unclogging drains, are necessary.
  • Extra Installations: Adding sump pumps or a dehumidifier will increase the total cost.

Labor costs can also vary, with local contractors charging around $100 per hour for labor, plus additional fees for specific services. For an accurate estimate, it’s best to consult with a professional contractor who can assess your specific situation and provide a detailed quote.

Should I Install a Vapor Barrier Myself?

It’s understandable to consider encapsulating your crawl space yourself, as it may seem like a straightforward task.

However, DIY encapsulation involves long hours of labor, dealing with moldy and unpleasant insulation, and working in a confined space. Without the proper experience, you might not completely seal the space, allowing outside air and humidity to enter, which could negate all your hard work. Professional encapsulation ensures a thorough and effective seal, providing reliable protection for your home.
