Sometimes called the cellar fungus, Wet Rot is a common cause of structural defects. It requires a moisture content of 50 to 60% but it does not spread through masonry and growth ceases when the moisture is removed.
To initiate growth from a spore the wood must be physically wet; in other words it must be subject to a source of water ingress, e.g., leaking gutters, wood in contact with damp masonry, etc. In practical terms the wood must have a moisture content in excess of 28-30%. Spores will not germinate on dry surfaces or surfaces which are not suitably wet. In other words, unless the wood is wet dry rot cannot become initiated.
If untreated wood is put in contact with damp infected masonry there is always the potential for the new wood to become infected.
