Rising damp


Rising damp is a type of moisture problem that occurs when groundwater rises through the walls of a building.

This happens when there is no effective damp-proof course (DPC) to prevent moisture from being drawn up by capillary action. As the moisture rises, it can lead to various issues, such as:

  • Damage to walls: The walls can become discoloured, and plaster may deteriorate.
  • Mold growth: Excess moisture creates a favourable environment for mold and mildew, which can affect air quality and health.
  • Structural damage: Over time, rising damp can weaken the structural integrity of a building.

Common signs of rising damp include damp patches on walls, peeling paint, and a musty smell. If you suspect rising damp in your property, it's advisable to seek professional advice for assessment and remediation.
