Causes of Rot

Finding the source of your rot problem is key to making sure it is dealt with effectively.

The main cause of rot is moisture in timbers. Wood destroying fungus feed off this moisture and as a result visible signs of dry rot or wet rot damage appear on the affected timber. Wet and Dry rot spores will only develop and take hold of timbers if the environmental conditions are correct.

In order to prevent rot it is essential that you fix ventilation issues and damp problems, such as rising damp, penetrating damp and condensation as they are the main causes of excessive moisture within a property.

How Rot Develops

Dry rot spores are always present in the atmosphere. Once they land on timber, they will germinate and produce hyphae (fine strands of fungal growth), if in the correct environmental conditions. These hyphae strands join together to form a mass called Mycelium which can vary in colour from grey to pure white, and these strands grow into and across the damp wood. It can also grow into materials such as plaster, mortars, bricks etc... in it's search more timber.

When the growth is advanced a fruiting body (Sporophore) may develop. This fruiting body takes the form of a “fleshy pancake”, the surface of which is orange/ochre coloured. A large numbers of spores generate from the centre of the fruiting body, under still conditions, and form the red “dust” often visible where there is a significant attack of dry rot.
