Woodworm treatment
Evidence-led woodworm treatment after active infestation and timber condition have been assessed.
Why diagnosis matters
Treat the cause, then repair the damage
Flight holes can remain for decades. Before treatment we consider fresh frass, hole edges, beetle life cycle, moisture and whether the timber is structurally sound.

Honest about what the work does—and does not—cover
Treatment does not restore lost structural section. Major repairs or uncertain structural capacity require separate input.
Common questions
About woodworm treatment
Are old holes proof of active woodworm?+
No. Fresh bore dust, recent emergence and timber moisture are more useful than old holes alone.
How long does treatment take?+
It depends on area, access, preparation and whether rooms or floors need clearing. We define the work sequence in the quotation.
Can I stay in the property?+
Product, ventilation and access controls determine this. Project-specific safety instructions are provided.
