Dry / Wet Rot Decay Nottingham & The East Midlands
There are two types of fungal decay that occurs in timber when the moisture content of timber rises above 20%. The most common form is the Wet Rot type decay, mainly comprising the Cellar fungus (Coniophora puteana) and the Mine fungus (Poria vaillantii).
The other type is the True Dry Rot fungus (Serpula lacrymans) of which there is only one.
Wet Rot decays are relatively simple to eliminate, by stopping the source of moisture and cutting out the affected timbers. All new replacement timbers should then be isolated from moisture by a physical damp proof membrane.
Dry rot is the most serious form of fungal decay in a building. The fungal strands (mycelium) can spread from affected timbers into the surrounding brickwork and plaster. Specialised strands develop within the mycelium and these supply water and nutrients to the growing Fruiting Bodies.
It is important that the type and cause of the fungal decay are correctly identified before any corrective action can be considered. It is for these reasons that it is important that a detailed diagnostic inspection is carried out by a qualified CSRT registered surveyor.
A detailed written report is issued outlining the extent of fungal decay found and a detailed schedule of works is issued on the proposed course of remedial action necessary.
