Woodworm Survey & Treatment Advice
Find out whether woodworm is active, historic or genuinely needs treatment before agreeing to unnecessary work.
Small holes in timber, powdery dust, damaged floorboards or beetle activity can be worrying, especially when buying a property. However, not every case of “woodworm” is active, serious or in need of treatment.
Dampserve provides woodworm surveys, timber inspections and written reports for homeowners, buyers, landlords, property professionals and mortgage-related cases. Our role is to inspect accessible timbers, assess whether evidence appears active or historic, consider the moisture conditions that may be supporting beetle activity, and recommend proportionate next steps.
Where treatment is genuinely needed, we can explain the options clearly. Where the evidence is historic, localised or unlikely to require treatment, the report will say so.
Survey first. Clear diagnosis. Treatment only where appropriate. If minor timber works or treatment are required, a separate no-obligation quote may be available on request.
Active or Historic?
We assess whether the evidence suggests current activity, old flight holes or historic timber damage.
Timber Condition
Accessible timbers are inspected for beetle evidence, decay, moisture risk and structural concern.
Written Reports
Clear reports for buyers, homeowners, landlords, surveyors and mortgage-related cases.
Optional Treatment
If treatment or minor timber repair is required, a separate no-obligation quote may be provided.
Do You Really Need Woodworm Treatment?
Woodworm treatment should not be recommended just because old flight holes are present. The important questions are whether the infestation is active, what species may be involved, whether the timber is damp, and whether there is any significant damage.
Woodworm Survey
Inspection of accessible timbers for flight holes, frass, beetle evidence, decay and moisture-related risk.
Woodworm Report
Written findings for buyers, sellers, landlords, homeowners, HomeBuyer Report follow-ups and mortgage-related requests.
Treatment Advice
Treatment is recommended only where evidence and conditions suggest it is necessary and proportionate.
Timber Repairs
Where timber is damaged, we can advise whether monitoring, treatment, repair or replacement is appropriate.
What Is Woodworm?
Woodworm is the common name for the larval stage of wood-boring beetles. The larvae feed within timber before emerging as adult beetles, leaving small exit holes. These holes may be recent or many years old, which is why inspection and interpretation are important.
The presence of holes alone does not prove active infestation. A surveyor will consider the condition of the timber, the presence of fresh frass, beetle species, moisture levels, ventilation, timber type, location and whether new holes are appearing.
Some cases require treatment. Others require moisture control, ventilation improvements, monitoring or no immediate treatment at all.

Common signs associated with woodworm
- small round exit holes in timber
- fine powdery dust, known as frass
- damaged or weakened floorboards, joists or beams
- tunnels visible in broken timber
- dead beetles near windowsills, lofts or floor areas
- new holes or fresh dust appearing during warmer months
Common Wood-Boring Beetles in UK Properties
Different beetle species behave differently, affect different timbers and may require different responses. Correct identification helps avoid unnecessary treatment and ensures serious cases are dealt with properly.
The most common species found in UK buildings is the Common Furniture Beetle. In older or damp hardwood structures, Deathwatch Beetle may be relevant. Powderpost Beetle and House Longhorn Beetle are more specific and should be assessed carefully where suspected.
The survey will consider the evidence available at the time of inspection and whether further opening-up, monitoring or specialist laboratory identification is required.

Examples of wood-boring insects
- Common Furniture Beetle – common in softwoods and some hardwoods.
- Deathwatch Beetle – often associated with damp hardwood in older buildings.
- House Longhorn Beetle – mainly associated with certain areas and softwood roof timbers.
- Powderpost Beetle – associated with susceptible hardwoods.
Survey First. Treatment Only if Needed.
Woodworm treatment should be based on evidence. Many properties have old beetle flight holes that are no longer active, especially in older floorboards, roof timbers or historic timber elements.
Dampserve’s first job is to inspect, diagnose and report. If the evidence suggests no active infestation or no significant risk, the report will say so. If treatment, timber repair or moisture control is needed, the recommendations will be proportionate.
Where minor treatment or timber-related works are required, a separate no-obligation quote may be available on request. There is no obligation to proceed.

- homebuyers
- mortgage-related reports
- landlords
- roof timber checks
- floorboard concerns
- second opinions
What a Woodworm Survey Includes
Subject to access, scope and property type, a woodworm or timber survey may include:
- inspection of accessible timbers
- assessment of flight holes, frass and beetle evidence
- comments on whether evidence appears active or historic
- assessment of timber condition and decay risk
- consideration of dampness, ventilation and moisture sources
- photographs and plain-English explanations
- recommendations for monitoring, moisture control, treatment or repair where appropriate
- cost guidance or a separate quote if requested and appropriate
When You Might Need a Woodworm Report
A woodworm report may be useful when:
- you are buying a property and woodworm has been mentioned in a survey
- a mortgage valuation or HomeBuyer Report has requested further timber investigation
- you have found new holes, fresh dust or beetles
- floorboards, joists, beams or roof timbers appear damaged
- a tenant, landlord or managing agent needs written findings
- you have received a quote for treatment and want the diagnosis checked
Common Woodworm Survey Outcomes
Historic Evidence
Old flight holes with no clear signs of current activity.
Active Infestation
Fresh frass, new holes or other evidence indicating activity.
Moisture Risk
Damp timber or poor ventilation increasing beetle and decay risk.
Timber Damage
Localised repair, monitoring or further investigation may be advised.
Treatment Needed
Targeted treatment where evidence supports it and access allows.
Woodworm Survey FAQs
Helpful answers about woodworm surveys, active infestations, treatment and reports.
No. Some evidence is historic and may not require treatment. A survey helps establish whether there are signs of current activity, timber damage, dampness or conditions that support infestation.
Possible signs include fresh powdery frass, new or clean-looking holes, beetles during the flight season and progressive damage. However, activity can be difficult to confirm from appearance alone, so professional interpretation is useful.
DIY treatment may be possible in very small, accessible areas, but it can miss hidden timbers, moisture causes or structural damage. A survey is recommended before relying on DIY treatment, especially before buying a property.
Not always. Many cases are historic or localised. The important thing is to know whether it is active, whether timbers are damaged, and whether treatment or repair is required before you make a decision.
Cost depends on the affected area, access, species, timber condition, moisture issues and treatment method. A survey is the best way to establish whether treatment is needed and what the likely cost may be.
Yes. We can provide written woodworm and timber survey reports for homeowners, buyers, landlords and mortgage-related cases, subject to inspection scope and access.
