Cold and wet weather during the winter is a leading cause of condensation and damp, which if left untreated, can lead to mould.

So what is condensation and how is it caused?

  • Moisture is always in the air, even if you cannot see it.
  • When the air gets colder it cannot hold all the moisture so tiny drops of water appear, which is condensation.
  • Condensation occurs mainly during cold weather, whether it’s raining or dry.
  • It appears in places where there is little movement of air, such as corners, on or near windows, behind wardrobes and cupboards and on north-facing walls.

Advice for homeowners

To help householders manage condensation issues, CORGI Fenestration recommends installers share four simple tips.

1. Produce less moisture

  • Cover pans and avoid leaving kettles boiling when cooking.
  • If you use paraffin and portable flue-less bottled-gas heaters that produce a lot of moisture and condensation, consider using an alternative means of heating.
  • Close bathroom doors and ensure extractor fans are on or windows are open when having showers or baths to allow damp air to escape.
  • Dry clothes outdoors.

2. Provide appropriate ventilation

  • Keep small windows ajar or trickle vents open all the time, if possible, especially when rooms are occupied.
  • Ensure kitchen and bathroom windows are open or extractor fans and vents to the outside are installed.
  • Close kitchen and bathroom doors when the rooms are in use.
  • Allow space for air to circulate in and around furniture and leave space between the backs of wardrobes and walls.
  • Install dehumidifiers to help dry out damp in newly built houses.

3. Insulate and draught-proof rooms

When installing draught proofing, ensure:

  • Permanent ventilators and chimneys are not blocked.
  • Rooms that have a fuel-burning heater are not draught-proofed.
  • Windows in bathrooms and kitchens are not draught-proofed.

4. Heat homes a little more

Key tips to remember:

  • Central heating should be set to provide background warmth in all rooms.
  • Thermostatically-controlled heating will help control heating and costs.
