wood decay

Wood decay is the process where wood deteriorates due to fungi or other organisms breaking down its cellulose and lignin, which are the materials that give wood strength and structure. This biological activity can weaken the wood, causing it to become soft, discolored, or crumbly. Decay typically occurs in areas with high moisture or poor ventilation, creating an environment for fungi to thrive. It’s common in structures exposed to the elements or in contact with soil. Proper maintenance, moisture control, and timely repairs help prevent or limit wood decay.
