How to Fix a Moldy, Dirty Crawl Space

Tony Hafford of TC Hafford Basement Systems explains how to fix a dirty, moldy crawl space. Since 1991, his company has helped homeowners in Maine and Southeast New Hampshire solve crawl space and basement moisture problems.

Crawl space moisture usually comes from two sources: ground water and outside air. Ground water can pool in the crawl space or evaporate from the ground. Outside air enters through the vents, and its moisture can condense on cold surfaces.

Tony outlines a five-step repair:

• Correct the drainage to stop water from pooling under the house.
• Seal the vents to keep outside air out.
• Encapsulate the crawl space with a durable vapor barrier.
• Air seal the sill plates to reduce air leaks.
• Control moisture and condensation with a crawl space dehumidifier.
