Closing Your Homes Crawl Space

Crawl Space Encapsulation

Crawl space encapsulation is when you seal your home to outside negative elements by closing your homes crawl space. These elements can include moisture, pests, or harsh temperatures.

Proper encapsulation often has a number of different elements based on the needs of your home.

Crawl Space Encapsulation

Insulation and Barriers

Protecting crawl space air starts with insulating the sides and the top of the crawl space. This helps regulate the temperature and the insulation is moisture resistant to help stop mold.

Putting a polyethylene barrier on the floor of the crawl space can also help add a layer of protection. The floor barrier helps keep any moisture from building up and affecting your air quality.

These also help regulate the temperature of your crawl space which helps your heating and cooling systems.


The danger of mold and mildew building up in a crawl space is one of the biggest problems homeowners have. Sealing the space and adding a dehumidifier help to protect the crawl space from too much moisture.

This is an important addition especially during the summer months when humidity and moisture can build up in the air. Your dehumidifier will work automatically keeping your crawl space dry and moving excess moisture out.

Protected Openings

Venting crawl spaces was once thought of as a solution but studies have shown that outside air can cause problems under the house. Sealing all air openings with weatherstripping helps maintain a good atmosphere under your house.

This means all doors and openings should also get set up for proper protection.

Crawl Space Encapsulation Benefits

Closing your home’s crawl space is a simple procedure that adds benefits many people don’t think about. These benefits can help protect your house, your health, and your budget.

Healthy Air

Your crawl space air does affect the atmosphere of your home. If you have issues with mold, that mold will cause problems with the air you breathe in your home.

This can also cause some serious health problems in your family. The CDC lists some of those problems:

  • Stuffy nose, coughing or wheezing
  • Burning eyes, skin rash
  • Immune-compromised people could get lung infections

You want to make sure your home air environment is safe. A crawl space encapsulation can help prevent any possible problems with mold.

Crawl Space - Healthy Air

Protects Your House

Water that has built up in your crawl space has the potential of seeping through the soil and hurting your home’s foundation. Too much moisture can also hurt your pipes and other equipment located in the crawl space.

Moisture is also the biggest attraction for termites. If you have a moist environment, it will encourage termites to come to live there. Termites will pass by houses with encapsulated environments because there is no moisture.

You don’t want to do anything to encourage termites to establish a colony under your house. Too often their damage isn’t seen until it is severe and expensive. This is another reason why closing your homes crawl space is a great idea!

Energy Efficient

Your floors will also feel the weather more without a protected crawl space. They will get hotter in the summer and cooler in the winter. This will cause your heating and cooling systems to work even harder to keep up.

You could see significant savings on your energy bill throughout the year with an encapsulated crawl space.
