Dry rot, also called brown rot, is wood decay stemming from fungal growth, which can destroy all kinds of wooden structures. When it occurs, fungi cause the disintegration of cellulose and hemicellulose, two carbohydrate molecules that make wood strong and resilient. What is left is brittle wood that often appears blocky. Dry rot will only destroy wood that is damp, generally with a moisture content not lower than 20 %. Hence, to solve dry rot, the source of moisture must be totally removed.
How Dry Rot Spreads
The dry rot fungus creates spores that air spreads around. If they get to moist wood, they will germinate, and if measures are not taken to arrest the process, the wood will disintegrate in time.
How to Detect Dry Rot
> Examine the wood. At first, fungus is going to look like cotton wool with water droplets on the surface if humidity is high.
> Check if the wood has cracks; darkened, sunken or shrunken parts; or growths that look like the outer part of a mushroom.
