What causes wood rot in the crawl space?

Section diagram

That musty smell in your home is a warning sign. High humidity and trapped moisture create the perfect breeding ground for wood rot. Unlike regular surface mold, wood rot actually devours the structural fibers of your wood beams, quietly destroying their strength and compromising your home's foundation.

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.

Find answers about our services and process

Poor indoor air quality in your crawl space is due to excess moisture, mold growth, and other contaminants. Air pollutants from your crawl space are transported to the rest of your home. To improve air quality in your crawl space and therefore your entire home, we recommend installing a complete crawl space encapsulation system. A proper encapsulation system will help maintain a stable humidity level in your crawl space and ensure that it stays clean.

Absolutely. Beyond impacting your indoor air quality and health, mold leads to wood rot, which results in severe and costly structural damage to your home.

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.
