Simply put, rising damp is ground water rising up through the wall of a construction, absorbed by the porous building material.

The upward movement of moisture through walls – and sometimes floors-happens via a process called capillarity. In order to better understand this, imagine a sponge being soaked in any liquid: gradually, the liquid will start pushing upwards as it is absorbed, transferring moisture to the upper levels.

Penetrating Damp is usually caused by water moving through walls from the outside of the building. There are two main causes of penetrating damp. The first one is building defects such as defective roof coverings, cracked brickwork, badly fitting windows, and faulty guttering and downpipes. The other form of penetrating damp is lateral penetrating damp which is caused when external ground, abutting the wall is above internal floor level.

Wet Rot

Wet Rot is a fungus that affects very damp timber. It can also cause decay in plaster, wallpaper and carpets. Wet rot spores are attracted to materials with a high moisture content.

Compared to dry rot, wet rot is less destructive as wet rot remains confined to the wet area only but still needs to be treated as it can affect a building’s structural integrity.

Cost of wet rot treatment

The cost of wet rot treatment depends on the severity and how much timber has been affected.
