Wood Rot

Wood rot occurs when excess moisture enters the building structure, which simulates the natural forest recycling process. The rate of decay depends on the timber used and moisture content of the timber.

The main wood rot fungi in buildings are the brown rots, which are split into Dry rot and Wet rot.

  1. Dry Rot (Serpula lacrymans) 28-30% wood moisture content.
  2. Wet Rot Cellar fungus (Coniophora puteana) prefers 50-60% wmc.
  3. Wet Rot Mine Fungus (Fibroporia vaillantii) Prefers 40-50%wmc.

It is essential that you have the infection inspected by a suitably qualified person as misdiagnosing the type of wood rot will have an effect on the cost and extent of remedial works.
