Dry rot / Wet Rot

Dry rot / Wet rot

Dry rot (Serpula Lacrymans) is the most serious type of rot. It can cause major structural damage to a house of any age. Dry rot can go unnoticed until it is at an advanced stage.

This type of rot can spread over materials that provide no nutritional value like plaster and masonry. It only needs a moisture content of above 20% to grow.

The fruiting bodies of Dry rot fungi that evolve during an attack on the wood create microscopic spores. These are then circulated around a room by currents of air which enables the Dry rot to spread.

Dry rot likes dark, unventilated areas such as:

  • Flat Roofs
  • Suspended timber floors
  • Derelict buildings
  • Buildings which have been left vacant/closed up for long periods of time
  • Where Rising damp and/or a water leak is present

Signs of Dry Rot

  • Wood shrinks and cracks in a cuboidal manner
  • Growth of pancake-like fungus
  • Mycelium
  • Dry timber can crumble between fingers
  • Musty mushroom-like odour

Wet Rot

Wet rot is more common than Dry rot. Decay is typically confined to the area where timber has become and remains wet with moisture content more than 50%. Firstly, finding the source of dampness and eliminating the moisture is always necessary.

Although Wet rot is not as serious as Dry rot, it can also cause serious structural damage if not treated.
