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.
