Signs of Rising Damp

Unlike woodworm which you may not know you have, rising damp is visually apparent in walls, skirting boards or timber. Do I have rd? Signs of rd are usually easy to spot. Check if you have any of these signs of rd:

  • Dark yellow or brown horizontal tide line on exterior or interior walls
  • Patches of damp on internal walls
  • Peeling or blistered paint or wallpaper
  • Stained or crumbling plasterwork
  • Damp smell or musty odour and
  • Rotting of timber floorboards.

Other signs of rd can be the crystalline deposit of salts (efflorescence) on concrete, stone or brick. This is when water evaporates from your walls and leaves salt deposits behind.

Green, black and white spots of mould that appear on damp walls are also signs of rising damp. Apart from unsightly damage to walls and floors, mould causes health risks especially for children and the elderly. Eczema, allergies and asthma have all been linked to exposure to breathing in mould spores resulting from high levels of indoor dampness.
