Condensation


Causes and treatment

Condensation occurs whether it is raining or dry outside. Condensation and mould growth is a sign that the air in your home is too wet.

The air around us contains moisture. Normal life in the home creates moisture. In fact, four people living in a 3 bedroom property can create 112 pints of moisture a week from just breathing, cooking, showering or bathing, and boiling the kettle.

Warmer air can hold more moisture than cooler air. So when air is cooled rapidly the moisture it contains can turn into water droplets known as condensation.

If condensation is left on a surface for long enough black mould will begin to grow. This is one reason why it’s important to reduce and manage condensation properly.

How to avoid condensation

Ventilate your home and allow air to circulate, use trickle vents and shut kitchen and bathroom doors when they are in use.

Produce less moisture by using correct lids on pans when cooking, venting your tumble dryer and avoid using paraffin or flueless bottle heaters. If possible don’t place furniture against external walls.

Insulate and draught proof your home, using draught excluders around window and doors including keyholes and letterboxes, loft hatches and electrical fittings on walls and ceilings. Efficient use of heating, keeping at a lower temperature for a longer time rather than higher for a shorter time.

How to treat condensation

Mould spots and spores can be removed using anti-fungal wash available from DIY stores.

If you want a cheaper alternative you can use a weak bleach and warm water mix - always follow the instructions.


If the above steps don't take the dampness away, it could be another issue like:

  • Rising damp - wet staining along the base of the ground floor, no more than a meter high
  • Bridging - usually just a damp patch caused by rubble, soil or plant against external walls
  • Penetrating damp - staining higher than a meter and clearly visible on walls and ceilings
  • Falling damp - caused by faulty roofs, the moisture collects and run down walls
  • Faulty gutters - rain water goods creates patches of damp around your home. If you see this, it is likely the gutter needs replacing
