What is Dry Rot?

Dry rot (Serpula lacrymans) is a fungus that consumes the cellulose in timber. Cellulose is a main component in timber which gives it strength and integrity, therefore the presence of dry rot can have a devastating effect within a property. Although the term ‘dry’ rot is used a moisture content of around 20% is required for it to grow, dry rot will not grow in well ventilated and dry conditions. Areas of high moisture in a property can be caused by a number of reasons e.g., a lack or absence of good ventilation. This type of dampness often goes unnoticed due to being behind walls or under floors. These are ideal conditions for dry rot to grow and spread which can cause severe damage to properties.

Evidence of Dry Rot

An invisible sign of dry rot can be a distinctive odour that accompanies it. If you sense a damp or musty smell which is progressively getting more noticeable this may be a sign of dry rot. There are a number of visible signs which are noticeable at various stages of growth.

1. Cubical cracking or checking on the surface.

2. Hyphae. Which can resemble grey cobwebs.

3. White Mycelium. Produced when dry rot spreads. It can resemble cotton wool.

4. A Fruiting body is produced to allow the dry rot to expel spores to create the same destructive cycle again.
