Understanding the problem
Moisture in a crawl space may affect framing, insulation, indoor air, pests, and comfort. Repair begins with controlling bulk water and drainage. Vapor barriers, sealing, dehumidification, insulation, or structural supports may then be considered based on the conditions found.
Common professional options
The appropriate approach must be based on an inspection. A professional may discuss:
- Drainage and water control
- Vapor barrier or encapsulation
- Dehumidification
- Support and framing evaluation
