How Crawl Space Encapsulation Can Improve Your Home

The crawl space is not the most glamorous area in a home. It’s a mostly forgotten space that many homeowners take for granted — until issues arise. Unfortunately, animals, water, mold, and other problems can invade a crawl space, causing issues in the home. That’s why crawl space encapsulation is important.
Crawl space encapsulation provides many benefits. Not only does it improve structural integrity, but it also enhances the resale value of your property. If you’re looking to make your home an investment, discover how crawl space encapsulation can enhance your crawl space.
6 Benefits of Crawl Space Encapsulation
Crawl space encapsulation keeps your home healthy and protects your crawl space from damage. Here are the major benefits of installing encapsulation.
1. Reduces Pest & Animal Nuisances
Rainwater and groundwater accumulate in crawl spaces and attract all types of insects. An infestation in the crawl space ruins the integrity of the home and costs homeowners a lot of money in exterminator fees.
A heavy vapor barrier seals a crawl space by lining the floor and foundation walls, making it much harder for pests to get in. Also, less moisture in the crawl space means pests will be less attracted to the area.
2. Prevents Mold Growth

HVAC systems used in an encapsulated crawl space help control temperatures and prevent mold from growing. Damp, dark spaces are a breeding ground for mold spores.
Mold in a home can cause a variety of health problems, which is another reason why crawl spaces should receive the same attention as other rooms. We also have a guide where you can learn more about protecting your home from mold.
3. Reduces Allergies
Respiratory issues caused by mold spores, pet dander, and dust significantly decrease when a crawl space is encapsulated. If you or a family member experiences asthma or allergies, it’s time for crawl space encapsulation.
4. Improves Energy Efficiency

Encapsulating your crawl space can also improve the energy efficiency of your home. By sealing off the crawl space and installing proper insulation, you prevent cold air from entering in the winter and warm air from entering in the summer. This makes it easier to regulate the temperature in your home, reducing your energy bills and lessening your environmental impact.
5. Protects Structural Integrity
A well-maintained crawl space supports the overall structure of your home. Encapsulation helps prevent moisture damage to the wooden beams and other materials that hold up your house. This can extend the life of your home and reduce the need for costly repairs.
6. May Increase Home Value
Potential buyers are likely to see an encapsulated crawl space as a major advantage. It shows that you have taken steps to protect the home from common issues like mold and pests, making your property more appealing and potentially increasing its market value.
💡 Fun Fact:
Around 50% of all the air in your home comes from the crawl space. Encapsulation makes the air you breathe healthier!
How Crawl Space Encapsulation Works
Crawl space encapsulation involves sealing the entire crawl space with a heavy-duty polyethylene barrier and installing other moisture management solutions. Here are the steps:


- Inspection and Cleaning: Inspect the crawl space for existing issues like mold, pests, or structural damage. Remove any debris, mold, or pests.
- Sealing Vents and Openings: Seal all vents and openings to the outside to prevent moisture and pests from entering.
- Installing a Vapor Barrier: Install a thick vapor barrier along the walls and floor of the crawl space, carefully sealing the barrier at all seams and edges.
- Insulating the Space: Add insulation to the walls of the crawl space to improve energy efficiency.
- Installing Drainage and Sump Pump: Install a drainage system and a sump pump to remove any water that accumulates in the crawl space, preventing flooding and moisture buildup.
- Dehumidification: Install a dehumidifier to keep humidity levels in the crawl space low, preventing mold growth and improving air quality.
Signs You Need Crawl Space Encapsulation
- Mold or Mildew: Visible mold growth in your home or crawl space is a clear sign that you need encapsulation.
- Pest Infestations: If you have a problem with pests in your crawl space, sealing it off can help keep them out.
- Musty Odors: Musty odors coming from your crawl space can indicate moisture and mold issues.
- High Energy Bills: If your energy bills are suddenly higher than usual, it may be due to poor insulation and water leaks in your crawl space.
