What is a Sealed Crawl Space?

At Carolina Custom Homes of Burlington, we build all of our custom modular homes with a sealed crawl space to provide better protection and air quality. Unlike vented crawl spaces, a sealed crawl space offers a number of benefits to your house and your family. But what is a sealed crawl space and how can it benefit your home?

What is a Sealed Crawl Space?

Traditionally, crawl spaces beneath a house are vented to allow air to pass beneath the house freely. Unfortunately, if you live in a humid area your crawl space might not be able to keep moisture out, which can lead to problems. Common issues associated with a vented crawl space are mold, mildew, wood rot, and poor air quality. Even worse, open crawl spaces can provide a home to pests and local wildlife.

A closed or “sealed” crawl space has no wall vents, meaning air cannot pass into the crawl space from outside your home. The ground in a sealed crawl space is covered with a moisture barrier which is sealed against the foundation walls. All gaps are sealed to create an air- and watertight sealed space. A sloped exterior grading around the foundation pulls water away from the house.

If you live in an area with a lot of moisture in the air such as the Southeastern United States, your home is at greater risk of developing mold and mildew. Having a sealed crawl space will prevent the buildup of moisture which can lead to mold and provides a number of additional benefits to your home.

  • Saves you up to 18% on your heating and cooling costs each year.
  • The moisture-free crawl space reduces the chance of mold and mildew.

  • Keeps your floors warmer in the winter and cooler in the summer.
  • The dry air prevents frozen pipes in the winter.
