Wet Rot FAQs

Can rot return after treatment?

Both wet and dry rot can return after successful treatment. Contractors can sterilise, treat and replace affected areas to eradicate any decay present, however, if the necessary conditions reoccur, the rot will start again. Spores are always present in the air and the only way to prevent wet rot and dry rot is to control the conditions.

Wet rot is caused principally by Coniophora puteana. Poria vaillantii is another important wet rot fungus and a number of less common fungi also occur. While each fungus has its own unique features, the general appearance of wet rot is similar – as is the treatment. Wet rot is typically confined to the area of dampness because the mycelium does not spread into walls.
