Reducing condensation

Useful tips to help reduce condensation in your home

Condensation forms when excess moisture in the air changes to liquid.

It's common when: 

  • there is excess moisture combined with cold surfaces, such as windows
  • there is little ventilation or poor air circulation 

Condensation is typically found in corners, behind furniture, and around windows and doors.

Things that can create excess moisture in your home:

  • cooking, including boiling the kettle
  • having a bath or shower
  • washing and drying clothes
  • overcrowding/pets

It would be useful to check the following and report to the ‘Repair Line’ if faults are found:

  • leaking pipes, wastes, gutters and/or overflows
  • rain coming through gaps in brickwork, the roof, window frames and around doors

If you follow our advice on preventing condensation, you should notice a considerable improvement within four to six weeks.

Prevent mould and remove moisture:

  • dry clothes outside whenever you can, either on a washing line or a clothes rail
  • if you need to dry washing indoors, don't put wet clothes on radiators, use a clothes rail and open a window
  • regularly wipe windows, walls and ceilings whenever there's any condensation to prevent the build up of mould
  • remove black mould by using a suitable cleaner

Open windows and ventilate your home:

  • allow moisture to escape and use the extractor fan (if you have one) when cooking and showering
  • keep a small window slightly open in the room that you are in

Keep your home warm:

  • keep the heating on low as much as possible in cold weather, even if you are not home
  • use the timer and thermostat to set your heating (this will help prevent pipes freezing too)

When possibe, contain moisture:

  • close the doors to the kitchen and bathroom when they're in use (even if you have an extractor fan) to stop moisture reaching other rooms
  • keep pan lids on to stop steam escaping when boiling or steaming food

Let air circulate:

  • keep furniture away from radiators to avoid blocking heat
  • leave a gap between furniture and walls to allow circulation
  • avoid putting too many things in wardrobes and cupboards
  • if you have a tumble dryer, vent through an outside wall or a window
  • avoid blocking ventilators or chimneys, they may be needed to provide ventilation to your gas appliances
