Rising Damp
WHAT IS RISING DAMP?
Rising damp occurs when moisture from the ground travels up through the walls of a property by capillary action. This leads to visible problems such as stained or peeling paint, crumbling plaster, and a musty smell.
One of the main causes is the failure or absence of a damp proof course (DPC), the protective barrier designed to stop moisture from moving upwards. If left untreated, rising damp can also encourage wet rot in timber, since persistent moisture creates the ideal environment for decay.
This is why rising damp should always be assessed quickly by a professional. A prompt survey and treatment will protect both the structure and appearance of your home.
Causes of Rising Damp
Rising damp is usually caused by:
- A missing or damaged damp proof course (DPC)
- Deterioration of an older DPC over time
- Poor drainage or excess ground moisture
- Inadequate ventilation that worsens the effects of damp
When water seeps into walls, it creates problems such as:
- Stained plaster and paintwork
- Black mould growth, especially in poorly ventilated rooms
- Rotting timber and the risk of wet rot
Addressing the issue early prevents further damage and saves on costly repairs.
