What is Dry and Wet Timber Rot?

Timber damage is mainly caused by fungal decay. Dry and wet rot are rarely seen in isolation. They are usually a result from another defect, such as, poor flashings, leaking pipes, leaking shower recess or broken roof tiles. Timber rot can be caused by a combination of tree elements.

  1. Warm moderate temperatures (over 40 deg C, will kill fungus)
  2. Large amounts of nutrient rich sapwood in the affected timbers
  3. Damp source, moisture is needed to allow fungus spours to germinate and spread.

Dry Rot

  • Dry rot only requires 20% moisture content to be present
  • Can spread/infect more timber than wet rot.
  • Dry rot is a term given to brown rot decay caused by certain fungus that deteriorates the timbers in buildings.
  • Dry rot can also affect masonry of the dwelling if left untreated.

Wet Rot

  • Wet rot affects timber which is wet, with moisture content of around 50%.
  • Wet rot, also known as Cellar fungus whilst generally not considered to be as intrusive as Dry rot, can still cause considerable damage over time if untreated.
  • Wet rot thrives in moist, damp environments especially where poor ventilation or a continuous moisture source is present.
  • Wet rot will not travel through masonry, and as such, stays localised at the source of the moisture and timber.
