What causes wood rot in the crawl space?

Section diagram

Persistent high humidity and moisture are the perfect breeding ground for wood rot. Unlike surface mold that stays on the exterior, wood rot devours the actual structural polymers inside the wood fibers, quietly destroying your home’s support beams from the inside out.

Root causes 3 most common

Unsealed crawl spaces allow moisture to constantly feed the fungus that causes wood rot.

Once rot starts, the wood loses its load-bearing capacity, leading to sagging floors and cracked drywall above.

Wood rot actually creates its own moisture via the digestion of wood, meaning it will continue to spread even if the original leak is fixed, unless properly treated.

Yes. Without proper moisture control, wood rot will continue to spread because it creates its own moisture as it digests wood. You must eliminate the humidity source and encapsulate the space.

Unfortunately, yes. Wood rot is the direct result of specific types of mold/fungal growth that consume the organic compounds in your home's structural wood.

Surface mold consumes starches on the outside of the wood and can be cleaned without damaging the structure. Wood rot eats the structural polymers inside the wood fibers, weakening the wood's strength and requiring serious repairs.
