Condensation Treatments

Condensation occurs when high levels of humid air are trapped within a building, where poor ventilation does not allow it to escape. This moisture then condenses when it touches cold surfaces such as windows, walls or ceilings; eventually leading to mould growth.

Improving insulation, double glazing and draught proofing can reduce the natural ventilation in properties.

What is Condensation?

Air can only hold a certain amount of moisture 'water vapour' - the warmer the air the more it can hold.

If this air is then cooled by contact with a cold surface (a window, mirror, metal window frame or even an outside wall) the air temperature is lowered and the vapour becomes water droplets - condensation. The point at which the air cools enough for the water droplets to form is known as the 'dewpoint'.

Everyday activity like cooking, washing, bathing or even just breathing releases moisture into the air. An average family of 4 can generate approximately 24 pints (14 litres) of water a day.

Tell-Tales Signs of Condensation

Condensation is usually a seasonal problem, most noticeable during the colder winter months. Obvious places condensation can appear - apart from windows, are cold walls and floors. Sometimes it can occur in hidden areas such as roof voids or suspended floors. Timbers in these particular areas may become susceptible to rot problems.

Most properties will suffer from some condensation dampness over time. However it becomes an issue if it is persistent and leads to other tell-tale signs such as:

  • Damp walls with blistering paint
  • Damaged and peeling wallpaper
  • 'Musty', damp odour
  • Black mould growth – along the edges of windows, skirting boards and wall/floor/ceiling junctions

If the dampness leaves a 'tidemark' on the surface there may be another cause such as water entering through rising damp or penetrating damp, faulty plumbing or loose roof tiles.

How to Stop Condensation

There are several steps you can take to reduce the likelihood of condensation becoming a problem, however they may not be practical all of the time:

  • Avoid drying clothes inside on radiators or in front of fires.
  • When cooking - cover pans, don't leave kettles boiling and use an extractor fan if possible.
  • Ventilate bathrooms and kitchens, keeping doors closed when they are in use.
  • Try to maintain a constant low level background heating, helping to ensure no rapid temperature changes and keeping wall surfaces warm.
