Have you noticed small round holes in your timber, or fine dust (frass) appearing on surfaces? These are common signs of a woodworm infestation.
Left untreated, woodworm can weaken structural timber, damage floors and roof timbers, and reduce property value. At Damp and Mould Solutions Ltd, we specialise in identifying and treating woodworm infestations across London, using proven methods that eliminate the problem at its source.
✔ Comprehensive woodworm surveys
✔ Targeted, professional-grade treatments
✔ Structural timber repair where required
✔ Long-term prevention and aftercare
What Is Woodworm and Why Is It a Problem in London Properties?
Woodworm refers to the larvae of wood-boring beetles that infest and feed on timber. Common species in UK properties include:
- Common Furniture Beetle (Anobium punctatum)
- Deathwatch Beetle (Xestobium rufovillosum)
- House Longhorn Beetle
- Powderpost Beetle
These beetles lay eggs in timber. Once hatched, the larvae bore through the wood for several years, weakening it from within before emerging as adult beetles.
Why it’s a serious issue:
- Hidden internal damage to timber
- Gradual weakening of structural elements
- Increased repair costs if left untreated
- Common in older London properties with poor ventilation
Signs of Active Woodworm Infestation in Timber
Identifying an active infestation is key to preventing serious damage.
Look out for:
✔ Fresh exit holes (clean, sharp edges)
✔ Fine powdery dust (frass) around timber
✔ Weak, brittle or crumbling wood
✔ Tunnels visible beneath the surface
✔ Live or dead beetles, especially between April and September
👉 Older holes without fresh frass may indicate a historic infestation, but a professional survey is essential to confirm.
What Causes Woodworm Infestations?
Woodworm infestations are strongly linked to moisture and damp conditions.
Common causes include:
- High timber moisture content (typically above 20%)
- Poor ventilation in subfloors or roof spaces
- Condensation build-up
- Leaking pipes or roof defects
- Damp environments such as basements
👉 Wood-boring beetles are attracted to damp, untreated timber, making moisture control a critical part of long-term prevention.
Is Woodworm a Structural Risk?
Yes—especially if left untreated.
Woodworm can compromise structural timber, including:
- Floor joists
- Roof timbers
- Wooden beams
- Subfloor structures
Over time, infestations can lead to:
- Sagging floors
- Weakened load-bearing timber
- Costly structural repairs
- Issues during property surveys or mortgage approvals
👉 Early intervention prevents serious structural damage and reduces repair costs.
