Do DIY Damp Proofing Solutions Work?

Dry rot is a serious form of fungal decay that can weaken the structural timber in your home. Caused by the fungus Serpula lacrymans, it thrives in damp, poorly ventilated conditions and spreads rapidly. Identifying dry rot early can save you time, money, and extensive repair work.

Common Signs of Dry Rot:

• Musty, Damp Odour
  A persistent, mouldy smell is often the first sign of dry rot. It’s especially noticeable in enclosed or unused spaces like basements and behind walls.
• Discoloured or Brittle Timber
  Affected wood may appear darker than normal and feel dry, crumbly, or soft to the touch. Cracking across the grain is a key visual indicator.
• White or Grey Fungal Growth
  You might see a cotton wool-like substance growing on surfaces. This is a clear sign of fungal activity, often a precursor to full-blown dry rot.
• Fruit Body Formation
  In advanced stages, dry rot forms a mushroom-like fruiting body with rust-coloured spores. This is a sign the fungus is well-established.
• Warped or Shrunken Wood
  Timber affected by dry rot may shrink, twist, or pull away from its fixtures as its internal structure breaks down.
• Flaking or Bubbling Paint
  Paint or wallpaper peeling without any obvious cause can indicate hidden moisture and rot beneath the surface.
• Fine Orange or Red Dust
  This spore dust, often found on nearby surfaces, signals the presence of an active fruiting body nearby.
