Dry rot, also referred to as brown rot, is wood decay that originates from fungi, which can damage any type of wooden structure. When it occurs, fungi cause the disintegration of cellulose and hemicellulose, two carbohydrate molecules that make wood strong and resilient. The effect is weakening of the wood and a stumpy look. Dry rot will only damage timber that is damp, with north of 20% moisture content. Therefore, the goal of any dry rod elimination project must be to remove the source of moisture.
