Know what you’re dealing with

Timber decay worries many homeowners, but most timber issues have a clear, fixable source, and it is often far less severe than feared. Beetle holes blamed on active woodworm are frequently historic, and fungal growth mistaken for dry rot is often harmless mould. Specialists inspect affected areas, test moisture levels, identify insect or fungal species, and trace contributing damp sources to find what is really happening in your structure, then recommend proportionate action.

Signs of timber decay in your home

Some beetle holes are decades old; others show active infestation. Get expert eyes on any of the following. Early diagnosis prevents unnecessary treatments.

Signs worth acting on

  • Fine, powdery dust (frass) near small round holes in timber
  • Spongy or springy floorboards, especially near external walls
  • White, cotton-wool-like strands (mycelium) on brickwork or timber
  • Mushroom-like fruiting bodies growing from skirting or masonry
  • Darkening or cuboidal cracking in structural timbers
  • Musty, mushroom-like odours in roof spaces or under floors

What causes timber decay in Northern Ireland?

Timber decay requires moisture, oxygen and a food source. Problems are often linked to leaking roofs, blocked sub-floor vents, defective rainwater goods or rising damp. The most common local triggers are:

  • Poor sub-floor ventilation in older properties
  • Leaking gutters or downpipes saturating wall plates
  • Bridged damp-proof courses leading to wet joist ends
  • Condensation buildup in unventilated roof spaces
