How to identify wet rot

Identifying wet rot is not an exact science.  For a start, there many different forms of wet rot that can affect timber in different ways. Also, without proper training, it can be difficult to identify the difference between wet rot and the more serious dry rot. That said, the guide below should be able to help with the initial identification of wet rot. 

We have compiled a series of pictures of wet rot to help you identify it in addition to the guide below.

Tell tale signs to identify wet rot

  • Look out for localised fungus growing on timber. 
  • Timber affected by wet rot will feel soft and spongy (even through a coat of paint) and look darker than surrounding timber.
  • When dry, the timber will easily crack and crumble into fine particles.   It can also be susceptible to shrinkage.
  • Some types of wet rot cause the wood to bleach.  This is common in doors and window frames.
  • Look for damaged or flaky paint.  If the paint finish is damaged, this can increase the risk of wet rot. If you suspect wet rot and the paint is not damaged, push a thin bladed knife into the painted timber.  The blade should stop after a short distance.  If it goes in up to the handle, it is almost certainly a sign of rot behind the paint.
  • Often wet rot is associated with a damp musty smell.

When no obvious fungus is present, wet rot can generally be identified and differentiated from dry rot by the differing colour of the decayed timber as well as the size and type of cracking by the timber as the wet rot progresses.

If you have any of the described conditions above, specialist wet rot treatment will be required to inhibit this.
