Signs of Active Woodworm Infestation — Book a Survey If You Spot Any

Woodworm damage is largely hidden — beetles bore through timber for years before the evidence becomes visible. These are the warning signs that indicate an active or recent infestation requiring professional assessment.

Signs of Active Woodworm Infestation in Timber

Small round exit holes in timber

Fresh holes with clean, sharp edges — typically 1–2mm for furniture beetles, larger for deathwatch beetles

🟤

Fine powdery dust (frass)

Cream-coloured bore dust beneath or around holes — the clearest sign of active larvae feeding inside the timber

🪵

Weak, crumbling or brittle wood

Timber that breaks apart easily under pressure — a sign of extensive internal tunnelling that may not be visible on the surface

🐛

Live or dead beetles

Adult beetles emerge between April and September — spotting them near timber, particularly in roof spaces or subfloors, confirms an active infestation

🔦

Tunnels visible in bare timber

Internal channels visible in split or damaged sections of wood, particularly in older joists, beams, and floorboards

Surveyor flagged woodworm

A homebuyer’s survey has noted evidence of infestation — get an independent specialist opinion before proceeding with the purchase

⚠ Is Woodworm a Structural Risk? Yes — If Left Untreated.

Wood-boring beetles spend years feeding inside structural timber before emerging. By the time exit holes are visible externally, significant internal damage may already have occurred. The structural elements most at risk in London properties are:

Floor joists and subfloor structures
Roof timbers and purlins
Wooden beams and lintels
Staircase stringers and treads

Consequences of untreated infestations include sagging floors, weakened load-bearing timber, costly structural repairs, and complications during mortgage surveys or property sales. Early treatment is substantially cheaper than structural remediation.

For property buyers: woodworm flagged in a homebuyer’s report requires an independent specialist survey before you can accurately assess the cost of remediation. Call us on 020 4542 6114 before exchanging contracts.

Why London Homeowners & Landlords Choose Damp & Mould Solutions

Many pest control companies treat the surface. We treat the cause. Woodworm infestations are driven by moisture — without addressing the underlying damp conditions, reinfestation is a matter of time.

Qualification

🎓 PCAQT Certified Specialists

Every survey and treatment is carried out by a PCAQT-qualified timber specialist — not a generalist pest controller. The industry’s recognised standard for woodworm and timber infestation diagnosis.

Root Cause

💧 Moisture Control Included

Wood-boring beetles target damp timber. Unlike surface-only treatments, we assess and address the moisture conditions driving the infestation — reducing the risk of it recurring.

Guarantee

🔒 Guaranteed Work

Our treatments come with a written guarantee. If the infestation recurs within the guarantee period, we return and retreat at no additional cost. Ask about guarantee terms when you call.

Speed

📅 Same-Week Appointments

We cover all London boroughs and typically book within the same week. Pre-purchase surveys accommodated urgently — call 020 4542 6114 and we’ll prioritise you.

Transparency

💷 Fixed-Fee, No Surprises

You receive a written quote before any work begins. No hidden costs, no upselling unnecessary treatments. We tell you what’s needed and what can wait.

A Proven Four-Stage Treatment Methodology

We don’t apply a blanket treatment and leave. Each property is assessed individually — because the right treatment for a Victorian subfloor is not the same as for a modern flat with a damp problem.

1

Woodworm Survey

PCAQT-certified specialist assesses timber, confirms active vs inactive infestation, identifies beetle species, and measures moisture — before recommending anything

Diagnosis first, always
2

Targeted Treatment

Permethrin-based surface treatments, deep injection for structural timber, or boron-based solutions for long-term protection — matched to your infestation, not a standard package

Species-specific treatment
3

Timber Repair

Where structural integrity is compromised, damaged timber is reinforced or replaced — restoring the section rather than just treating the surface

Structural restoration
4

Moisture Control

We identify and address the damp conditions that attracted beetles in the first place — improving ventilation, reducing humidity, and advising on long-term protection

Prevents reinfestation

Why DIY Woodworm Treatments Fail

Over-the-counter treatments are widely available, but the vast majority of cases we’re called back to treat are properties where DIY products were tried first. Here’s why.

Surface treatments alone do not reach larvae

DIY products

  • Penetrate only a few millimetres into timber surface
  • Cannot reach larvae tunnelling deep inside structural wood
  • Do not address the moisture conditions attracting beetles
  • Provide no guarantee or follow-up if reinfestation occurs
  • Risk incorrect product for the beetle species present

Professional treatment

  • Deep injection penetrates structural timber fully
  • Species correctly identified before treatment selected
  • Moisture cause assessed and addressed alongside treatment
  • Written guarantee on all work carried out
  • Structural repair included where timber is compromised

Frequently Asked Questions

How much does woodworm treatment cost in London?
Treatment typically ranges from £1,450 to £2,500 for a full residential property in London, depending on the extent of the infestation, the species present, and the treatment method required. All costs are confirmed in writing after survey — there are no hidden fees and no obligation to proceed. Call 020 4542 6114 for a no-obligation estimate based on your property.
How quickly can you visit for a woodworm survey?
We typically have availability within the same week across all London boroughs. If you are under time pressure — for example, a property purchase is in progress — call us directly on 020 4542 6114 and we will do our best to prioritise an urgent appointment.
What is included in the woodworm survey and report?
Your written survey report includes: identification of the beetle species present, confirmation of active vs inactive infestation, moisture readings for all affected timber, photographs of all exit holes, frass, and damage, a recommended treatment plan with method options, and a fixed-fee cost estimate. The report is suitable for insurance purposes, property sales, or obtaining quotes from other contractors.
Do you offer a guarantee on woodworm treatments?
Yes. All our woodworm treatments come with a written guarantee. If the infestation recurs within the guarantee period, we return and retreat at no additional cost. Guarantee duration depends on the treatment type — call us on 020 4542 6114 to discuss the terms applicable to your property.
I have tried a DIY treatment and the woodworm has come back. Can you help?
Yes — this is one of the most common situations we deal with. DIY treatments rarely penetrate deep enough to reach larvae inside structural timber, and they do not address the moisture conditions that attracted beetles in the first place. We carry out a full assessment, identify what was missed, and provide a permanent solution. Call 020 4542 6114 to discuss your situation before booking.
