Dry rot, also “brown rot” or “wood rot” is one of the most damaging forces of household wood in the world.

Despite its name, dry rot wood needs moisture to produce spores. Wood rot problems show up in basements and crawl spaces where water and humidity are issues.  

crawl space - before and after encapsulationAn outbreak of dry rot commonly occurs several months after a water event, such as flooding, bursting washing machine hoses, a failed water heater, or leaking pipes.

An indication that your home has an issue with dry rot is the appearance of a "red brick dust," fungal spores that are waiting for the proper conditions to start to grow.

Architect's Journal reports that dry rot can grow through damp mortar, concrete, masonry and behind plaster. This makes dry rot damage repair complicated and expensive. And, it can lead to future problems if the wood rot treatment isn’t properly performed.

The best way to repair wood rot is to prevent it in the first place. This can be solved by controlling moisture by sealing and dehumidifying the space. Thrasher Foundation Repair uses a combination of vapor barrier or crawl space liner with a self-draining dehumidifier, to remove unwanted moisture and prevent future incursions.
