Common Questions

We have tried to answer some common questions from our clients. If you have any further questions, please contact us.

What is Woodworm?

Despite the common name, woodworm is not actually a worm at all. It is the larval stage of a wood boring beetle. There are several beetles referred to as "woodworm", the ones found in the UK being the Common Furniture beetle (the most common), the House Longhorn beetle and the Deathwatch beetle (also common in the south west).

The most obvious sign of a problem are small holes in woodwork. If the beetles are active (i.e. boring out of the wood) there will be signs of dust (frass) from the holes.

The most common treatment is application of an insecticide, however the larval stage of the beetle can be one or more years so evidence of larvae boring out of the wood (and then being killed by the treatment) can be seen long after the treatment has been applied.

Do I have a damp problem or a condensation problem?

We find a lot of problems with reported damp are actually caused by condensation. If problems are caused by condensation it is often easily solved by some simple steps by the homeowner.

Condensation is caused by moisture in the home condensing on cold surfaces. These are often windows and cold walls within the house. Condensation can be seen as a film on surfaces, often accompanied with black mould. The best way to prevent condensation is to ensure a good circulation of air throughout the house.

It's not uncommon to find older properties that were free from condensation suddenly experiencing problems after replacement windows are fitted or old fireplaces blocked up. Old windows and open chimneys would have provided sufficient background ventilation to prevent condensation. Part F of the building regulations describes ventilation requirements in more detail.

If you have condensation we suggest the following tips which will reduce or even eradicate the problem altogether:
  • If you have window trickle vents open them to allow air to circulate. If you don't have trickle vents in your windows (common with older uPVC installations) we would recommend the installation of trickle vents into the windows.
  • Allow air to circulate around furniture. Try not to position large furniture tight against walls.
  • Try not to use flueless gas or paraffin heaters as these produce a lot of moisture when running. Also drying clothes inside will produce a lot of moisture.
  • Fit extractor fans in areas of high humidity. i.e. bathrooms and kitchens.
  • Open internal doors to allow air to circulate throughout the house.
  • Every breath we exhale is saturated with water vapour. We exhale around 1.5 litres of water every eight hours. At night try and open a window or trickle vent.

If required we can fit a passive ventilation system which draws air from the roof space and creates a positive pressure within the house producing a constant, low volume, circulation of air. We have had a great deal of success with these units with many clients reporting a clearing of all previous condensation and mould. Please contact us for further details.
