Preventing Crawlspace Dampness and Structural Wood Rot After a Flood

The Crawlspace Moisture Trap

When a water heater or plumbing fixture ruptures, water rapidly seeks the lowest point of gravity, often pooling in unconditioned dirt or concrete crawlspaces. Trapped humidity in these confined spaces fosters wood decay fungi (such as Serpula lacrymans) that compromise the structural load-bearing capacity of floor joists. Explore our specialized basement and crawlspace extraction solutions.
