Searching for information about the cost of crawl space encapsulation? If so, don’t hit that back button because you’ve landed on the right page. This article will cover what crawl space encapsulation is precisely, how much it costs, the benefits of an encapsulated crawl space, and more.

What Is Crawl Space Encapsulation?

Crawl space encapsulation means sealing a crawl space to protect the area from moisture and other harmful elements. Encapsulation involves sealing the crawl space vents and applying a vapor-retarding barrier to the floor and walls of the crawl space. A dehumidifier is often added as well.

Learn the many benefits of crawl space encapsulation and how it can help you save on costly repairs, improve energy efficiency, and maintain your home's value.

How Is Crawl Space Encapsulation Done?

Encapsulation is a multi-step process that’s generally as follows:

  1. The crawl space is thoroughly cleaned. Any debris or contaminants are removed, and any moisture or water damage is addressed.
  2. Next, the vents are sealed, and the crawl space floor and walls are covered with a thick, vapor-retarding barrier. This barrier helps to prevent moisture from entering the space and can also help to regulate the temperature of the area.
  3. Crawl space encapsulation may also involve the installation of a dehumidifier to ensure the humidity level in the crawl space and the home’s living area remains low.

Does My Home Need An Encapsulated Crawl Space?

Unless you live in an extremely arid region, you could benefit from an encapsulated crawl space. Consult with a professional to determine whether or not an encapsulated crawl space is necessary for your home.

The Benefits Of Crawl Space Encapsulation

The benefits of encapsulating a crawl space are numerous and include the following:

  • Improved indoor air quality – One of the main benefits of crawl space encapsulation is improved indoor air quality. This is because some of the air in your crawl space enters your home’s living area via the stack effect. If your crawl space is full of mold, the air coming out of it will be as well. By preventing crawl space moisture, encapsulation helps reduce the growth of harmful mold and bacteria that can lead to respiratory problems and other health issues for anyone living in the house.
  • Prevent pest infestation – Encapsulation can also help prevent pests such as wood-eating insects, rodents, and snakes from entering the crawl space and potentially gaining access to the rest of the home. These unwanted critters can also wreak havoc on the wooden structures in the crawl space, the home’s wiring, insulation, etc.
  • Protect your home’s structural integrity – Moisture in a crawl space can lead to rotting wood, deteriorated insulation, and even structural damage. Therefore, encapsulating a crawl space is an effective solution that can help prevent expensive home repairs.
  • Possible increased energy efficiency – Although we can’t guarantee it, customers have reported that encapsulating their crawl space reduced their heating and cooling costs. This might be because the air flowing into the home from the crawl space is drier after encapsulation, and drier air is easier to heat and cool.
  • Home buyers like encapsulated crawl spaces – Since a properly encapsulated crawl space improves air quality, energy efficiency, and overall home integrity, it can be a deciding factor for potential buyers when it comes time to sell. Studies show homes with crawl space encapsulation can yield a higher sale price than those without.

Cost Of Crawl Space Encapsulation

The cost of crawl space encapsulation can vary based on various factors, including the crawl space size, your geographical region, the materials used, and the extent of the damage or mold present.

While crawl space encapsulation is a relatively expensive home improvement, keep in mind that the cost will be well worth it in the long run, as it can help prevent costly damage to your home’s foundation and ensure the air flowing into your home is dry and clean. Although we can’t guarantee it, encapsulation might also save you money on energy bills by providing a more efficient heating and cooling system.

To determine the exact cost of crawl space encapsulation for your home, consult a professional contractor who can assess your needs and provide a detailed estimate.

What’s The Difference Between Crawl Space Insulation And Encapsulation?

Crawl space insulation prevents heat loss or gain from your home's crawl space. This type of insulation is typically made from fiberglass, foam board, or spray foam and is installed between the floor joists. The insulation acts as a barrier against heat transfer, ensuring that your home remains warm in the winter and cool in the summer.

The insulation acts as a barrier against heat transfer, ensuring that your home remains warm in the winter and cool in the summer.

Encapsulation, however, is designed to prevent moisture from entering your crawl space and creating problems. Without the vapor-retarding barrier used in encapsulation, moisture can accumulate in your crawl space and lead to mold and mildew growth, as well as structural damage.

How Long Does Crawl Space Encapsulation Last?

The answer to this question largely depends on the quality of materials used and the ongoing maintenance of the encapsulated crawl space. Generally, a properly installed and maintained crawl space encapsulation could last a lifetime, as long as it’s taken care of. However, the lifespan will vary based on climate, humidity levels, overall wear and tear, etc. We recommended a professional inspection of the crawl space encapsulation system every few years to assess its condition and to perform any necessary repairs.

Do I Need To Add A Dehumidifier To An Encapsulated Crawl Space?

Generally speaking, encapsulated crawl spaces are designed to keep moisture out of the crawl space, reducing the need for a dehumidifier. However, a dehumidifier may still be necessary in areas with high humidity to ensure that the space remains dry.

When selecting a dehumidifier for your encapsulated crawl space, choosing one appropriately sized for your crawl space and capable of effectively extracting moisture from the area is essential.

Is Encapsulating A Crawl Space A Possible DIY Project?

We strongly advise against crawl space encapsulation as a DIY project. While attempting encapsulation as a do-it-yourself project to save money may be tempting, it’s rarely worth the risk. Encapsulation requires a substantial amount of knowledge, expertise, and specialized equipment. A lack of experience and knowledge may result in mistakes with severe long-term consequences, such as moisture buildup, mold growth, and wood rot.

Crawl space encapsulation is the process of sealing off the crawl space area under a home from the outside environment.

Moreover, crawling around in a crawl space can be hazardous. Crawl spaces often contain sharp objects, pests, and toxic substances. It’s also difficult for most homeowners to correctly diagnose the underlying issues that need correction in their crawl space.

Professionals with extensive experience with crawl space encapsulation can quickly diagnose any underlying issues with your crawl space and are equipped with the latest technology and equipment. They understand precisely what materials and techniques to use, ensuring that the encapsulation is done correctly and the homeowner can reap maximum benefits in the long run.

Overall, crawl space encapsulation is a highly effective way to protect your home and family from the harmful effects of moisture, pests, and other pollutants. If you’re considering encapsulating your crawl space, working with a qualified professional is important to ensure the job is done correctly. With the right approach, crawl space encapsulation can provide you with years of protection and peace of mind.
