How Much Does it Cost to Encapsulate a Crawl Space in 2023? Pros, Cons, and Everything You Need to Know

If you own an older home, chances are you have a crawl space. While older homes are charming and full of character, they come with a specific set of maintenance tasks. Caring for a crawl space should certainly be on the list.

Decades ago, builders believed that crawl spaces served as a buffer between your home and the wet earth below. Now we know that this narrow and often unventilated area beneath our homes is prone to moisture buildup, pest infestations, mold, and rot.  One of the best ways to address the potential risks of an untreated crawl space is encapsulation. Crawl space encapsulation will improve the air quality of your home, reduce the risk of foundation damage, and increase your energy efficiency. 

Is Crawl Space Encapsulation Worth the Cost?

Is crawl space encapsulation worth the cost? The short answer is yes! Crawl space encapsulation is a one-time solution that will keep your crawl space clean, dry, and pest-free for years. You’ll love the benefits including:

  • Improved air quality: Encapsulating a crawl space prevents moisture from entering the space and reduces the risk of mold growth improving your air quality.
  • Reduced energy costs: A sealed crawl space regulates the temperature of a home, reducing the need for heating and cooling and ultimately lowering energy costs.
  • Protection against foundation damage: Moisture in a crawl space can lead to wood rot, invite termites, and cause foundation damage. Encapsulation helps protect you against these potentially expensive problems.

On average, encapsulation can last anywhere from 10 to 25 years! Crawl space encapsulation is a solid return on investment for homeowners. While the cost of encapsulation can vary based on the size of the crawl space and other factors, the improved energy efficiency and reduced risk of foundation damage can ultimately save you lots of money in the long run.

How Much Does It Cost to Encapsulate a Crawl Space?

It’s hard to pinpoint the exact cost of crawl space encapsulation because it varies based on several factors but the general range is between $3,000–$10,000. Here are some factors professionals will consider when creating an estimate for your crawl space encapsulation.

  • Size of the crawl space: A larger crawl space will require more materials and labor.
  • Accessibility: A crawl space that is difficult to access may require additional labor and equipment.
  • Condition of the crawl space: A crawl space requires any repairs or pre-treatment will cost more than a crawl space that is in relatively good condition.

Because there are so many different considerations that affect the cost of crawl space encapsulation, it’s important to get a personalized estimate from a professional encapsulation company. Many companies even offer free estimates before they begin work.

Cons of Encapsulating a Crawl Space

Crawl space encapsulation is truly an investment in the quality and longevity of your home. When done properly, the drawbacks of crawl space encapsulation are little to none. However, there are some risks associated with improper or hasty installation.

  • Cost: The one-time cost of an encapsulation can be significant, which may not be feasible for all homeowners.
  • Risk of improper installation: If the crawl space encapsulation is not installed properly, it can actually create new problems or exacerbate existing issues.
  • Limited ventilation: Sealing a crawl space can limit ventilation, leading to excess humidity and moisture control issues.

Before deciding to encapsulate a crawl space, be sure to get a solid estimate from a reputable company or, if you choose a DIY approach, to thoroughly educate yourself.

Do I Need a Dehumidifier If I Encapsulate My Crawl Space?

In most cases, effective crawl space encapsulations incorporate powerful dehumidifiers to keep the environment sealed and regulated. Sealing a crawl space without a mechanism to remove future moisture can create new problems—including mold and mildew growth. Proper ventilation in the form of a dehumidifier is critical to ensure that your crawl space encapsulation works year after year. This is especially true in high-humidity areas like the American Southeast.

It’s important to note that not all crawl spaces will require a dehumidifier. We recommend consulting a professional to determine if a dehumidifier is necessary for your specific situation.

Can I Seal My Crawl Space Myself?

You may be tempted to tackle crawl space encapsulation yourself and we understand! DIY encapsulation may be more affordable, but it also carries a higher risk of mistakes that can lead to expensive problems down the road.

In contrast, professional encapsulation services typically provide a higher quality of work and give you confidence that the encapsulation is installed correctly. Talk with a professional in your area to determine which option is best for you.
