Condensation & mould



Condensation is caused by the air in your home being too wet. Air always contains a certain amount of water. The warmer the air the more it can hold. When the air is cooler, moisture is released to surfaces such as windows, walls and mirrors.

This short video shows what you can do around your home to help stop condensation forming and leading to mould.

If these don’t work or aren’t practical for you, please contact us so we can book a visit and find a solution.

What causes condensation?

There are three main causes:

  • Too much moisture is produced in your home
  • Not enough ventilation for air to move around
  • Your home/room is too cold

What can I do to reduce condensation in my home?

  • Kitchen

    When washing clothes or cooking keep the door closed and open windows. Keep lids on pans when cooking and use extractor fans where fitted.

  • Heating

    Keep your home warm. Warm air can hold more moisture causing less condensation to form on surfaces. This is particularly important in the winter months as the colder weather can reduce the temperature in your home much quicker. If you’re not sure how to use the heating controls in your home ask us for an information pack.

  • Bathroom

    Run the cold water for a bath before the hot water to reduce the amount of steam. Close the bathroom door and open the window while taking a shower or running a bath to allow steam to escape. Use the extractor fan if you have one.

  • Windows

    Whenever possible, open your windows slightly to air your home. Where fitted, always keep the trickle vents open.

  • Drying clothes

    When the weather allows, always dry your clothes outside. If you use a tumble dryer, make sure the moist air is piped outside. Do not dry clothes on radiators, instead place them on a clothes rack in a cool room with the door closed, window open and extractor fan on where possible.

  • Ventilation

    Make sure all vents in your home are open. Never block up or cover air bricks, flues or ventilators.

  • Furniture

    Leave a gap between your furniture and outside walls. Do not over-fill wardrobes, cupboards and chests of drawers as this creates air pockets. Avoid putting mattresses directly on the floor.

  • Loft

    For safety reasons, and to avoid blocking ventilation or damaging loft insulation.

  • Outside walls

    Remove any items such as bicycles and bin bags leaning against the walls of your home. These can prevent ventilation and sunlight from warming the walls.

What should I do if I see mould is forming?

Condensation can lead to mould if surfaces stay wet. If you see small black, grey or green spots on your walls or other surfaces, mould is forming. To remove mould:

1. Wash the affected area thoroughly.
Use non-ammonia soap or detergent, or a commercial cleaner in hot water and scrub the entire area affected. Use a stiff brush or cleaning pad on uneven surfaces.

2. Rinse and dry.
Use a damp cloth to rinse any residual detergent off the treated surface.

3. Disinfection.
Only use disinfectant once you complete steps 1 and 2. Use a fungicidal product and wash the affected surface. Follow the instructions carefully including all safety guidance.

4. Use a fan heater.
Use until the area is completely dried out, if you have one available.

If mould continues to be a problem:
