Dry Rot (Serpula Lacrymans)

Dry rot is a fungus that destroys timbers in buildings, and if left untreated, can lead to structural damage. It can travel through other materials including masonry, and therefore has the ability to spread quickly.

Dry rot will only start in damp timbers, therefore the cause of the dampness must be established. This could be a leaking roof, gutter, or even a leaking shower tray or washing machine. Condensation is a major contributor, as are rising or penetrating damp.

Signs to look for are:

  • Damp, musty odour.
  • Cracked or shrinking wood.
  • Soft orange coloured pancake fruiting bodies.
  • Rust coloured dust close to fruiting bodies (spores).
  • Growth of white cotton wool-like mycelium.

All affected timbers need to be replaced with pre-treated timber, and any nearby timbers at risk should be treated.

As dry rot has the potential to travel quickly and cause severe damage, it must be dealt with by a specialist.

If the source of the dampness is corrected, and the timber is allowed to dry out completely, dry rot can eventually be controlled, but this can take a long time and is often not practical.
