What is condensation?

Condensation happens when warm, moist air meets cold surfaces. As the warm air cools, it releases moisture, forming a wet or damp surface or water droplets. When water is left on surfaces it can cause black spots of mould to form.

If there is a lack of ventilation from open doors and windows, and air is not properly circulated, moisture gets trapped within the home as it has nowhere to escape. This moist air will then find a cold place to settle, leading to condensation.

What is damp?

Damp is commonly found when excess moisture in the air that has no way of escaping settles on cold surfaces. Damp can be caused by water coming in from outside, plumbing problems, not having enough heating in your home or a fault with the property such as poor ventilation, leaks or issues with damp proofing.

Possible faults and signs of damp include:

  • Leaking pipes
  • Rising damp
  • Rain seeping in through a damaged door, window or roof
  • Blocked guttering
  • Gaps and cracks in brick work
  • Growing circles of damp on walls or ceilings
  • Blotchy patches on walls
  • Wet and crumbly plaster
  • Signs of mould or mildew
  • Drips and puddles.

What is mould?

Mould is a type of fungus produced in damp and humid conditions. It’s usually found on cold surfaces such as walls and in areas of the home where there is less ventilation and air flow.

Staining, spotting or discolouration accompanied by a stale or musty odour are signs of mould.

Mould spots are often found on skirting boards and walls behind furniture, after moist air has settled on cold surfaces. Mould can also appear on your furniture, clothing, curtains and blinds.
