Common causes
Homeowners often compare vapor barriers and encapsulation when they see exposed soil, damaged plastic, musty odors, humidity, or damp crawl-space materials.
What homeowners can safely observe
Look for exposed soil, torn or missing ground cover, damp areas, standing water, condensation, and whether odors seem to move into the home.
When to request help
Request help when you are unsure whether a simple ground vapor barrier is enough or whether drainage, sealing, or humidity control should be considered.
How they differ
A vapor barrier is usually focused on the ground surface. Encapsulation can include heavier liners, wall treatment, sealing details, drainage, and humidity control.
