Wet rot is a term applied to a range of fungal attacks. Typically the timbers at risk have moisture content in excess of 50%. Each type of fungus has its own characteristics and may attack timber in different ways but they also have common features, the most important being they all limit their attack to damp timber. Unlike dry rot, there is little threat to masonry or dry timbers. Extensive chemical treatment is not generally necessary and remedial action is directed towards removing the moisture source, improving ventilation and replacing affected timbers. Dry rot and wet rot can be easily confused by inexperienced surveyors. It is therefore advisable to instruct a CSRT qualified surveyor to diagnose the type of decay and recommend appropriate remedial treatment.
