Woodworm in Exeter
Two very different kinds of timber, one careful approach
Few cities ask more of a woodworm surveyor than Exeter. Inside the old walls, around the cathedral and along the medieval streets that survived the war, you find genuinely ancient oak — the kind of dense, slow-grown hardwood that death watch beetle quietly works through over decades. Step out into St Leonard's, Heavitree and Pennsylvania, and the picture changes to Victorian and Edwardian terraces built almost entirely in softwood. Go further, to Topsham, Crediton and the river villages, and you meet cob, lath and oak frames hundreds of years old.
Each of these materials behaves differently, attracts different beetles and needs a different treatment. Spraying old oak as though it were a pine joist achieves very little; treating cob without first dealing with its moisture wastes your money. That is why, in Exeter more than almost anywhere, getting the species right comes before anything else. We survey first, identify the beetle, and only then recommend a method — or, just as often, tell you the infestation is historic and needs nothing at all.
Local property stock
Where Exeter homes pick up woodworm
The risk is rarely random. It follows the age of the timber, the moisture in the building and how well the sub-floor and roof are ventilated.
Historic oak in the old city
Beams, bressummers and joist ends in the cathedral quarter and medieval streets are prime death watch beetle territory — 3mm holes in damp, aged oak that demand a careful, structural assessment.
Victorian & Edwardian terraces
St Leonard's, Heavitree and Pennsylvania are full of softwood floor joists and roof rafters. Their sapwood is the favourite food of the common furniture beetle, especially where air bricks have been blocked.
Devon cob & timber frame
Cob, lath and oak-framed cottages in Topsham, Crediton and the villages hold moisture by nature, drawing wood-boring weevil and furniture beetle into already-damp timber.
Loft & roof spaces
Rafters and purlins are the most common site of active woodworm we find. If your loft houses bats, treatment may need a bat check first — bats are legally protected under UK law.
Suspended timber floors
Ground-floor joists over poorly ventilated voids stay cool and damp — ideal for beetle. We lift boards where needed to inspect and treat the underside properly.
Sale & survey findings
A lot of Exeter cases surface when a buyer's survey flags timber. A clear treatment certificate and 30-year guarantee keeps a sale moving and reassures the lender.
How we treat it
Identify first, then match the method
There is no single woodworm treatment. The right one depends on the species, the timber and how deep the attack has gone — which is why every Exeter job begins with a survey.
Water-based spray
A permethrin spray is the standard professional treatment for active furniture beetle in accessible softwood joists and rafters. It is touch-dry in hours and most homes are treated in a single day.
Boron gel & paste
For dense oak, joist ends bedded into damp walls and death watch beetle, boron paste penetrates deep where spray cannot reach — ideal for Exeter's historic structural timber.
Structural timber repair
Where beetle and decay have weakened a beam or joist beyond treatment, we splice, resin-repair or replace it — sympathetically, on older and listed buildings.
Fix the damp first
Damp timber is what keeps beetle active. In cob and older properties we address the moisture source so treatment lasts — see our dry rot & damp service.
