Identifying wet rot is not always easy because some of the symptoms of wet rot are similar to those of dry rot. Wet rot should be identified by a professional who can tell it apart from other forms of rot by the differing colour of the decayed timber as well as the size and type of cracking it exhibits as the wet rot progresses.

The common signs of wet rot include:

• Darkened timber – darker than surrounding timber

• Soft and spongy timber

• Cracked appearance that may crumble to touch when dry

• Localised fungus growth

• Shrinkage 

• A damp, musty smell
