 | Rising Damp
Rising Damp occurs when there is a failure of an existing damp course or no damp course in a building.
Moisture is drawn up into the brickwork and plaster from the foundations. When the moisture evaporates it leaves behind salts.
This photograph clearly shows the effect of rising damp. The brown staining of the wall finishes is due to the salt contamination of the plaster. |
 | Wet Rot
There are a variety of different Wet Rot Fungi. They feed off wood and require saturated conditions to thrive. The moisture content in affected wood will often be over 20%.
Wet Rot has a root system (mycelium) which spreads in a different way to Dry Rot. A Wet Rot outbreak tends to be far more localised than with Dry Rot. Most of our Wet Rot treatments take place in floors.
The treatment of Wet Rot will depend upon the extent of the outbreak. All treatments will require the cure of the source of water. The subsequent removal of affected timbers and new timbers are isolated from damp brickwork. |
 | Dry Rot
Dry Rot is a fungus which feeds off wood. It requires a lower level of moisture than the Wet Rot fungi.
It has a root system (mycelium) that can spread behind wall plaster and into most building materials.
The treatment will vary depending upon the type, age of the property and the extent of the outbreak. All treatment will require curing the source of water. The removal of decay affected timbers and mycelium. Invariably plaster removal is required in order to sterilise brickwork so that the attack is eradicated. In some situations even solid floors have to be removed. |
 | Woodworm
Woodworm is the term most people use to describe the presence of wood boring insects. The most common insects found in Britain are:
· The common Furniture Beetle
· Weevil
· Death Watch Beetle
· Bark Borer
The larvae of these beetles feed off wood. Often the only signs that they have been dining out on your wood is the exit bores holes they leave. If the infestation is active you may notice the “saw dust” they leave behind. |
