Woodworm holes found in timber are caused by the larvae of beetles that feed on the timber. Larger holes on the surface of the timber are formed when the adult beetle emerges from the timber to mate.

There are a number of species of woodworm, and the precise method of treatment will depend on which species is attacking the timber.

For best results, the identification and treatment of woodworm should be carried out by experienced contractors – particularly in the case of widespread infestation, or where the more destructive species of woodworm are involved. If you would like us to help you then call us now.

In houses, particular care is needed under poorly ventilated floors, shower rooms, bathrooms and such. It’s not unusual to find a light to moderate infestation in a house and then discover that the sections of floor under the kitchen sink or shower tray are very heavily infested, often with structural damage.

Damage caused by the Common Furniture Beetle can be quite shocking. Most of the time though, remedial work involves replacement of the odd floorboard or two and a spray with a suitable HSE approved insecticide.

Fungal Decay refers to attack of timber by a wood rotting fungus. Any timber with a moisture content above 19% can be affected – hence the necessity to keep the external fabric of a building in good condition. A damp course should be installed and particular attention should be paid to underfloor ventilation of ground floor timber floors and ventilation of loft areas. When an internal plumbing leak has occurred it is essential that the dampened timbers are thoroughly ventilated as the situation dries out. True Dry Rot (Serpula Lacrymans) is the most serious form of fungal decay in buildings. It can penetrate masonry to affect neighbouring properties and has the ability to produce its own moisture to dampen previously dry timber. In a suitable environment the rate of growth can be up to 1 metre a year, so prompt diagnosis and treatment are essential.

An attack of dry rot requires specialist knowledge of the fungus and its characteristics to determine the extent of treatment. The first essential is to establish the cause of the dampness and cure it. Removal of all the affected timber is vital, as is the thorough sterilisation of masonry in the affected area. Specialised treatment is also required to all replacement timbers and to areas of exposed masonry where timbers are to be re-fitted.

Wet rot treatment consists of establishing the source of the dampness, curing it and removing the affected timber. In certain circumstances wet rot can turn to dry rot so it is important to create a dry, healthy environment to prevent its re-occurrence.

Rising damp is probably the most well know form of damp problem that home owners have to contend with. As the name suggests, rising damp comes up into the building from ground level. Once dampness has penetrated the wall structure it rises up through the pores of the brickwork, or other building material, by a process known as capillary action. This is the same process by which moisture will rise up a paper towel if the bottom edge is suspended in water
