Condensation and your home

Sometimes you may notice condensation in your home. Occasionally this is confused with damp and, although it can lead to this, there are many simple things that can be done to keep your home safe, warm and dry.

What is condensation?

Particularly during the winter months, condensation (water residue on surfaces such as tiles or windows) can be an issue. This is usually because we start to feel the cold more and spend more time inside our homes, which lads to greater humidity and a build-up of moisture. Although condensation can turn into damp and mould, there is a lot that can be done to prevent this.

What causes condensation?

The top three causes of condensation are:

  • Too much moisture in the air.
  • Not enough ventilation.
  • Cold surfaces within the home.

What are the signs of condensation?

If your property is suffering from condensation and damp, you may notice the following:

  • A build-up of moisture on your windows.
  • Musty, damp smell.
  • Water running down walls and windows.
  • Wallpaper peeling.
  • Damp patches on walls.
  • A build-up of moisture on windows.
  • Musty, damp smell.
  • Mould growth (especially on exterior walls).
  • Wall staining.

What can I do to prevent condensation?

There are several things you can take to help prevent condensation issues from appearing within your home:

  • Ensure that any washing machines or tumble dryers are correctly vented.
  • Dry clothes outdoors to prevent excess moisture escaping into your property (if this is not possible, open doors or windows).
  • Ensure that your kitchen or bathroom doors are closed to avoid excess moisture from escaping into other rooms.
  • Cover your pans when cooking to avoid the steam from escaping.
  • Use an extractor fan, if you have one, when cooking or showering. Alternatively, open a window for at least 15-20 minutes.
  • Cover fish tanks and move houseplants outdoors if necessary, as both pets and plants produce moisture.
  • Wipe down and dry surfaces after you finish using them.
  • Do not overfill wardrobes or cupboards. Overfilled spaces such as these are breeding grounds for mould as the air cannot easily circulate.
  • Place wardrobes against internal walls, if possible.
  • Keep furniture at least 50mm away from surrounding walls so that air can easily move around your home.
  • Ensure that your home is adequately heated.
  • Open the windows slightly in rooms that you regularly use.

What can I do to tackle condensation?

If your home already has condensation-related issues, it is important to get these sorted as soon as you notice the signs. Here are some ways you can tackle the problem in the first instance:

  • Wipe down affected walls and window frames with a fungicidal wash.
  • Dry clean or machine wash mildewed clothes and shampoo mouldy carpets.
  • Redecorate using fungicidal paint or, if wallpapering, use a fungicidal resistant paste.
