Woodworm in Plymouth
Why Plymouth's timber is so often at risk
Few cities sit more squarely in the weather as Plymouth. Driving rain off the Atlantic, salt-laden air rolling up Plymouth Sound and a dense stock of pre-war and naval-era housing combine to keep timber moisture levels high for much of the year. Damp timber is the single biggest reason woodworm stays active — and Plymouth's older homes have it in abundance.
Much of the city was rebuilt and expanded around the dockyard and the naval base, leaving long rows of solid terraces in Devonport, Stoke and Keyham with suspended timber ground floors, cellars and slate-clad roofs. Add the post-war estates in Plympton and Plymstock and you have decades of original softwood joists, rafters and floorboards still in service. Where sub-floor air bricks have been blocked or a cellar stays damp, the common furniture beetle (Anobium punctatum) finds the cool, moist, sapwood-rich timber it favours and quietly works through it, season after season.
We treat woodworm right across Plymouth and the surrounding area, from the seafront properties of the Hoe down to Plymstock and out to Plympton. Every job starts with a proper diagnosis, because the right treatment depends entirely on which beetle you have and whether it is still alive in the wood.
Where we find it
The Plymouth properties most prone to woodworm
After surveying timber across the city, the same property types and the same hidden spots come up again and again.
Naval-era terraces
The dockyard terraces of Devonport, Keyham and Stoke were built in softwood, with suspended timber floors over damp sub-floor voids — classic furniture beetle territory.
Seafront and Hoe properties
Homes exposed to wind-driven rain off Plymouth Sound carry higher timber moisture in roofs and bay windows, which keeps any infestation active for longer.
Cellars and sub-floors
Plymouth's hillside terraces often have part-cellars and under-floor voids where joist ends sit close to damp masonry — the wettest, most vulnerable timber in the house.
Roof spaces and rafters
Slate roofs that have let in water, or lofts with poor ventilation, leave rafters and purlins damp enough for beetle to take hold high up where it is rarely noticed.
Converted flats and HMOs
Large houses around Mutley and Mannamead split into flats and student lets share floor and roof timbers, so an infestation in one unit can affect the others.
Post-war estates
Homes in Plympton and Plymstock are newer but still built with softwood joists and lofts — and decades on, original timber there is well within reach of the beetle.
Spot it early
Signs of active woodworm
Caught early, woodworm is straightforward to treat. In a damp coastal climate like Plymouth's, it pays to check timber every spring.
- Round exit holes. Crisp 1–2mm holes from the common furniture beetle; pale, sharp-edged holes suggest a recent emergence.
- Fresh bore dust (frass). Fine, gritty powder like tiny sawdust piles beneath floorboards, skirting and loft timber — a sign of live activity.
- Weak, crumbling timber. Floorboards and joist ends that flex, crumble at the edge or sound hollow when tapped — common where sub-floor damp lingers.
- Live or dead beetles. Small brown beetles near windows in spring and summer, or dead ones on sills and in cobwebs.
How we treat it
The right method for Plymouth timber
Identification decides everything. We match the treatment to the species, the location and the moisture in the wood.
Water-based spray
A water-based permethrin spray is the standard treatment for active furniture beetle in accessible floor and roof timber. It is touch-dry within a few hours, so most homes are back in normal use the same day.
Boron paste and gel
For structural timber, joist ends bedded into damp masonry and hard-to-reach areas in cellars and sub-floors, deep-penetrating boron paste carries the treatment into the heart of the wood.
Damp control and timber repair
In Plymouth's wet climate, fixing the underlying damp is half the job. Where decay has gone structural, we splice, resin-repair or replace affected timber so the building is sound, not just treated.
Treating in a roof? Bats are legally protected, so we always check before any work in a loft. Our surveyors follow Property Care Association standards.
