Condensation

Moisture that forms when warm, humid air meets a cold surface — often on windows, in corners, or behind furniture placed against external walls.

Penetrating damp

Moisture that enters a property from outside, often through a defect in the roof, walls, guttering or window seals.

Mould growth

Visible black, green or white growth on walls, ceilings or fabrics, often appearing after prolonged damp or a leak.

Common signs

  • Visible mould on walls, ceilings, window frames or fabrics
  • Persistent condensation on windows or cold surfaces
  • Damp patches that don't dry out
  • Water staining on ceilings or walls
  • A musty or damp smell in a room
  • Peeling paint or wallpaper
  • Recurring moisture after a leak has been "fixed"
  • Poor ventilation — extractor fans not working, trickle vents blocked
