What is Wet Rot?

Wet rot is the common name which is used to describe a number of wood destroying fungi species. The most common wet rot wood destroying species is “Coniophora Puteana” which is otherwise known as cellar fungus.

Wet rot fungi can affect timber that becomes damp and the fungi grows by breaking down the cell walls of the wood and feeding on the nutrients. This process can be extremely damaging to the structure of your home and it may result in the loss of structural strength of the timber.

How Big A Problem Is Wet Rot?

Firstly, wet rot should not be confused with the similarly named timber condition, dry rot. Although wet rot does not spread like dry rot, if it is left untreated, it could still cause structural damage to your home.

Wet rot targets unprotected timber that is affected by damp. Due to the often-poor weather conditions in the UK, wet rot is extremely common. Wet rot can cause structural defects within buildings, especially if they are unchecked with no wet rot treatment programme implemented.

In short, any unprotected timber in your home that becomes damp is at risk of a rot attack.

How Wet Rot occurs?

This may seem obvious, but in order to grow, the timber requires to be affected by a source of moisture. There are several things you can look out for that can cause damp that allows the growth of wet rot on timbers. Rising damp, Plumbing leaks and Penetrating damp from gutters, downpipes, defective masonry pointing and poor external render can all cause water penetration to affect built in timbers and result in an outbreak of wet rot.

Wet rot spores germinate and grow as damp raises the moisture content of the timber above 20% putting the timber at risk. Once the timber becomes infected, it will eventually lead to the timber losing its strength.

Where is Wet Rot commonly found?

When unprotected timber in your property becomes damp then the timber could be at risk of an attack of wet rot. Every home is different, and the rot can occur anywhere, however, wet rot is commonly found in ground floors and roofs with timbers built into the external walls of your property at risk if they are affected by damp.

The most common causes of damp affecting timber in your home are due to building defects such as penetrating damp caused by defective external render or pointing, rainwater goods, and roof defects. Also, internal plumbing leaks, rising damp or damp areas below floors can cause the wet rot to germinate and affect the timber.
