Should You Get a Crawl Space Encapsulation for your Home?

how much value does an encapsulated crawl space add to your home

In the realm of home improvements, crawl space encapsulation has become a buzzworthy term, raising questions about its necessity and impact on property value. This article delves into the concept of encapsulated crawl spaces, exploring whether this investment is truly worthwhile. By examining the pros and cons, cost considerations, and their potential influence on real estate value, homeowners can make informed decisions about the relevance of crawl space encapsulation.

What is an encapsulated crawl space?

Crawl space encapsulation is a comprehensive process designed to shield the vulnerable crawl space beneath homes. This involves enveloping the crawl space in a robust vapor barrier, typically thick plastic sheeting. The primary objective is to establish a protective barrier, barring the entry of moisture and outside air. This strategic measure is essential to fortifying the structural integrity of the entire home by safeguarding it against potential threats.

Encapsulation goes beyond mere sealing; it is a meticulous undertaking aimed at creating an environment that is inhospitable to factors that could compromise the crawl space. This includes addressing issues related to poor air quality, increased energy costs, and the risk of mold growth. By encapsulating the crawl space, homeowners take a proactive step toward mitigating potential problems, ensuring a healthier and more resilient living space.

Does your house need it?

Determining the necessity of crawl space encapsulation involves a thorough assessment of various factors unique to each home. Homes equipped with crawl spaces are often susceptible to a range of issues, including poor air quality, escalated energy expenses, and the pervasive threat of mold growth. The decision to encapsulate should be based on a careful evaluation of the specific conditions and needs of the home’s crawl space.

Poor air quality can stem from the infiltration of outside air carrying allergens, pollutants, and moisture. Encapsulation acts as a shield against these elements, fostering a healthier indoor environment. Additionally, encapsulation contributes to energy efficiency by maintaining a consistent temperature in the crawl space, resulting in lower heating and cooling costs. Mold prevention is another crucial aspect, as encapsulation inhibits moisture accumulation, thus mitigating the risk of mold and mildew growth.

Pros and Cons of Encapsulated Crawl Space


  • Improved Air Quality: Encapsulation acts as a barrier, preventing the infiltration of outside air and moisture. This leads to enhanced indoor air quality by reducing allergens and pollutants.
  • Increased Energy Efficiency: Consistent temperature maintenance in encapsulated crawl spaces contributes to improved energy efficiency, translating into lower heating and cooling costs.
  • Mold Prevention: By keeping moisture at bay, encapsulation significantly reduces the risk of mold and mildew growth, safeguarding both the crawl space and the entire home.
  • Pest Control: Sealed crawl spaces serve as a deterrent to pests, preventing issues like termite infestations and rodent invasions.
  • Property Value Enhancement: A well-encapsulated crawl space can contribute to increased property value, making it an attractive feature for potential buyers.


  • Initial Cost Considerations: Crawl space encapsulation can incur significant upfront costs, ranging from $5,000 to $16,000, depending on various factors.
  • Access Challenges: The encapsulation process may make it more difficult to access the crawl space for repairs or maintenance due to the presence of insulation materials and vapor barriers.
  • Moisture Risks: Poorly executed encapsulation or inadequate ventilation can lead to moisture buildup, potentially causing mold growth and structural damage.
  • Regular Maintenance Requirements: To ensure the effectiveness of encapsulation, regular maintenance and inspections are essential. Neglecting this can diminish the long-term benefits.

How much would an encapsulated crawl space cost?

When considering crawl space encapsulation, understanding the cost is vital, and it varies depending on factors like size, condition, and the chosen approach.

DIY options

DIY encapsulation kits provide an option for homeowners looking to take on the project independently. These kits typically include vapor barriers and installation instructions. While DIY encapsulation can be cost-effective, it demands a high level of skill for proper sealing and insulation. The cost of DIY kits generally ranges from $1,500 to $5,000, making them an attractive choice for those with the necessary skills.

Professional options

Opting for professional services ensures a thorough and expertly executed encapsulation. Professionals conduct detailed inspections, address existing issues, and implement the encapsulation process effectively. The cost of professional encapsulation varies widely, ranging from $5,000 to $16,000. This higher cost reflects the quality of work and expertise involved, providing homeowners with peace of mind regarding the effectiveness of the encapsulation.

The decision between DIY and professional encapsulation ultimately depends on factors such as the homeowner’s skill level, the complexity of the crawl space, and their preference for a long-lasting and effective solution.

Is it better to DIY or hire professionals?

Choosing between a DIY approach and hiring professionals is a crucial decision that depends on several factors.

DIY approach

For homeowners with a high skill level, a penchant for DIY projects, and a desire to save on costs, the DIY approach can be enticing. DIY encapsulation kits offer a more budget-friendly option, but success depends on the individual’s ability to effectively seal and insulate the crawl space. This approach is suitable for smaller, less complex crawl spaces where the homeowner is confident in their skills.

Professional hiring

Opting for professional encapsulation provides a comprehensive and expertly executed solution. Professionals bring a wealth of experience, conduct thorough inspections, and ensure that the encapsulation process is carried out effectively. This option is more suitable for larger, more complex crawl spaces or situations where the homeowner lacks the necessary skills or time. While the cost is higher, the assurance of well-executed encapsulation and long-term benefits justifies the investment.

The decision to DIY or hire professionals depends on the homeowner’s skill level, the complexity of the crawl space, and the desired longevity and effectiveness of the solution. While DIY can be cost-effective for some, professional encapsulation offers expertise and peace of mind for a more significant investment.

Is it worth it to add an encapsulated crawl space to your home?

Assessing the worth of adding an encapsulated crawl space involves a comprehensive cost-value analysis, considering both short-term and long-term implications.

Cost vs. Value

Determining the return on investment requires evaluating how much value encapsulation adds to a home. Encapsulated crawl spaces are increasingly valued in the real estate market as they address common issues and contribute to a healthier living environment. A well-maintained, encapsulated crawl space can enhance the overall appeal of a property, potentially justifying the initial expense.

Adding crawl space encapsulation can be a good idea

The decision to add crawl space encapsulation to your home is multifaceted. By understanding the pros and cons, weighing the costs associated with DIY and professional options, and considering the potential increase in property value, homeowners can make informed choices. While the initial investment may be significant, the long-term benefits in terms of improved air quality, energy efficiency, and property value enhancement position crawl space encapsulation as a valuable investment in the overall well-being of your home.
