In certain climates, a sealed crawl space is recommended for many reasons. If you live in an area that gets a lot of rain or near a water source, you have water evaporating from the dirt under your house. If your crawl space is unventilated, this moisture is trapped under the house and has nowhere to go other than settling on the foundation wall, joists and subfloor of your home. This can create mold that can be harmful to your family, or it can cause wood rot in your floor joists or subfloor. Excessive moisture in the crawl space can also infiltrate your insulation.
Sealing your crawl space can help with energy efficiency as well. Because heat rises, warm air will rise to the upper levels or attic space in your home, drawing the cooler air from the crawl space up through the lower level floors. Sealing your crawl space can help prevent heat loss in the winter.
A sealed crawl space can also help prevent invasion by insects and other unwanted animals. Even if the 
animals cannot get into the living areas of your home, they can still create an unhealthy living environment in the home.
The quality of the air you breathe every day in your home is directly affected by the quality of the air in your crawl space.
If you choose to seal your crawl space, it is important to make sure there is proper ventilation for your home based on the area where you live and the type of home you have.
