Can dry rot be invisible but still cause damage?

Dry rot can indeed be invisible while still causing significant damage. This phenomenon occurs because the fungus responsible for dry rot, known as Serpula lacrymans, often develops within the wood structure, thriving out of sight. The initial stages of dry rot may not present any visible signs, such as discoloration, cracking, or an unpleasant odor, making it challenging to detect without proper inspection techniques.

Despite its invisibility, dry rot compromises the structural integrity of wood by breaking down cellulose and lignin, which are essential components that give wood strength. As the dry rot progresses, it can lead to severe structural issues, posing risks to buildings and other wooden structures. Therefore, it's crucial for field representatives to be aware that dry rot can exist undetected and warrant thorough inspections to identify potential hidden infestations before they manifest more significant problems.
