Dry Rot

Dry rot is the most serious type of timber decay. It is a fungus that destroys the cellulose component of wood turning it brown, and eventually reducing timber to a dry and crumbly consistency.
How To Identify Dry Rot

Dry rot has a distinct mushroom smell and white fungal growth often with yellow and lilac tinges.

The reddy brown fruiting body produces spores, which are deposited as a layer of brick red dust throughout the building.

Unlike wet rot there is extensive fungal growth and distinct cuboidal cracking of the timber.

Wet Rot

Wet rot is a general term used to describe the majority of fungal species responsible for timber decay. This rot attacks wood in damp conditions and can cause significant damage over time, if left unidentified and untreated.

There are a number of signs to look for, which could indicate the presence of wet rot:
Distortion, discolouration, softness, cracking and the loss of strength to the timber
Smell - there may be a damp musty smell.
Visible fungal growth - this may sometimes occur.


Damp can affect any home or property for a number of reasons. Damp problems may be caused by:

Lack of maintenance
Poor build quality
Design defects
Deterioration of building fabric
If damp is left untreated it will only get worse and be expensive to rectify the longer the problem is ignored.

Untreated dampness may also cause other problems like dry rot or wet rot. The longer damp is left untreated, the more damage it may cause to internal decorations and disruption to homeowners.


If you suspect the presence of woodworm in your property, we recommend that you arrange with a qualified surveyor to inspect the problem and provide effective woodworm treatment.

The cost of woodworm treatment will vary depending on a number of factors.
