Crawl Space
Moisture & Humidity
What’s happening beneath your home often works against it.
In Chattanooga’s humid climate, crawl spaces stay damp for much of the year. Warm air carries moisture through open vents, moving water upward from exposed soil. Over time, this constant humidity takes a toll on wood framing, insulation, and the air you breathe inside your home.
An Unsealed Crawl Space Stays Vulnerable
Cleaning up the damage is only half the battle.
If you’ve had crawl space remediation done, the mold, rotting wood, and deteriorated materials have been removed and the space is clean again. But the conditions that led to those problems in the first place are still there. Open vents still let humid air in. Exposed soil still releases moisture. Without sealing the space, the same issues can return over time. Encapsulation is what changes those conditions for good.

Space Encapsulation
Sealing the space is what keeps moisture from coming back.
Crawl space encapsulation creates a controlled, dry environment beneath your home. We install a heavy-duty vapor barrier across the floor and up the foundation walls, seal all exterior vents, and add a dehumidifier to maintain consistent humidity levels. Together, these components block the primary ways moisture enters: through the soil, through the air, and through the walls. The result is a stable crawl space that stays dry year-round.
Encapsulation vs. Remediation
Fixing the damage and then preventing it from returning.
If your crawl space already has mold, rotting wood, or deteriorated insulation, those issues need to be addressed first. That’s crawl space remediation: removing existing damage and restoring the space to a clean condition. Encapsulation is what comes next. It seals the space so that moisture cannot return and cause the same problems again. If you aren’t yet at the encapsulation stage, can learn more about our remediation work here.
