RISING DAMP
What is Rising Damp?
Rising damp happens when ground moisture is drawn up through porous walls like brick or stone. It can cause stains, peeling paint, mould, and crumbling masonry, usually up to 1.5 m high.
​
Damp-Proof Course (DPC)
A DPC is a barrier near the wall base that blocks moisture. Modern ones use plastic sheeting; older buildings may lack or have failed DPCs, leading to damp issues.
WOODWORM FESTATION
What is Woodworm?
Woodworm refers to damage caused by wood-boring beetle larvae that feed on timber. Infested wood may show tiny round holes, fine powder (frass), or weakened structures.
​
Prevention and Treatment
Keep wood dry and well-ventilated, treat affected areas with insecticide, and replace severely damaged timber to prevent further infestation.
DRY /WET ROT
What is Dry Rot?
Dry rot is a fungal decay that attacks damp timber, causing it to crack, shrink, and lose strength. It spreads through masonry and can cause major structural damage.
​
Wet Rot
Wet rot occurs when timber stays damp for long periods. It softens and darkens the wood but remains localized to the moisture source.
