Damp And Condensation

The main cause of dampness is condensation which can lead to mould growth in your home, if left untreated this will lead to health risks and will cause your wooden window frames to rot.

Mould is formed when the moist air produced by cooking, washing or drying your clothes indoors hits cool surfaces such as walls and mirrors. This condenses and forms water droplets. This moist air will rise when it is warm and will often end up on ceilings and in the rooms upstairs.

Mould will grow on walls, ceilings, furniture, furnishings and clothing in drawers and cupboards.

Types of damp

There are two basic types of damp:

  • Penetrating damp – which occurs when water enters your house externally, which can be through a crack in the wall or a loose roof tile.
  • Rising damp – occurs when there is a problem with the damp proof course or the membrane and water rises from the ground onto the walls and roof.

How to prevent

You can control excess moisture and prevent further dampness occurring by keeping the kitchen and bathroom doors closed to prevent steam going into the colder rooms.
You should keep a window or extractor fan open when cooking and washing. This will allow the steam to escape.

You can also buy condensation channels and sponge strips from any DIY store. These are fitted to windows and will collect the condensation, thus preventing windows to rot and will avoid damp from forming under the sills. However you should take care that these devices are fitted properly.
