Timber Preservation

Timber Infestations

Woodworm is the commonly used term for a number of wood boring insects which lay their eggs on or in timber and whose larvae bore through the wood leaving a network of tunnels, damaging and weakening the structure.

Woodworm attack is varied - both in the type of timber which different species infest and their larval life-span which can range from ten months to 11 years. This means that accurate identification by the surveyor is the first essential step because not all infestations need treatment.

Woodworm Survey

A thorough survey of the building is needed to locate the areas of active woodworm infestation. In domestic buildings it may be necessary to lift sections of floorboards and gain access to lofts and roof voids.

Where timbers are heavily infested by woodworm and wood rot and have to be cut away and replaced, our surveyor will also consider all the structural aspects of the building.

Woodworm Treatment

We use chemical insecticidal formulations applied by spray, brush or paste that carry very little odour and permit re-occupation of treated areas within 1 hour.


We will provide a 10 year guarantee for timber infestation treatments. An additional GPI (guarantee protection insurance) guarantee can be purchased which will run alongside our own guarantee, please request a leaflet for further information.
