Condensation

How Do I Solve the Problem?

There are four main steps that will help you reduce condensation in your home.

All four steps will probably need to be taken, though steps one two and three are the most important and can be done at little cost.

1. Ventilate your home - let the wet air out

You can do this without creating a draught - keep a small window or vent open when there is moisture in the room.

More ventilation is required in 'wet' rooms like the kitchen and bathroom areas. When in use open the windows wide and close the doors to prevent the moisture reaching other rooms, especially bedrooms which are often colder and more likely to get condensation.

Use extraction fans where fitted, for at least 20 minutes after having a bath or a shower - long enough to dry out the room.

Try to open your windows at least once a day, but remember to be secure and shut them when you go out.

Ventilate cupboards and wardrobes. Avoid overfilling as this stops the air circulating. Where possible, position wardrobes and furniture against internal walls.

2. Produce less moisture

Some ordinarily daily activities produce a lot of moisture very quickly.

When cooking, cover pans and turn down to simmer. Do not leave kettles boiling

Dry washing outdoors on a line if possible, or put it into the bathroom with the door closed and the window open or the fan on

If using a tumble dryer, make sure you vent it outside (unless it is a self-condensing type) Avoid drying washing on a raadiator or in front of a radiant heater

Avoid using paraffin and portable flueless bottled gas heaters as these heaters introduce a lot of moisture into the air

3. Heat your home a little

In cold weather, the best way to avoid condensation is by keeping background heating on all day, even when no one is at home. I

f you don't have heating in every room then open doors to these rooms and let some heat in and allow the air to circulate.

It is advisable to heat rooms to at least 10°C even when not occupied. Living rooms in use should be heated to about 20°C.

4. Insulation and draft proofing

Insulation and draught proofing will help keep your home warm and will also cut fuel bills. When the whole home is warmer, condensation is less likely.

Loft and wall insulation are the most effective forms of insulation.  Draughtproof windows and external doors without covering up vents.

If you have reason to believe that your home could benefit from an improvement to loft or wall insulation, please contact the Energy Efficiency Officer on 01200 413235.

What to do if you find evidence of condensation

If there are black marks or mould growth then wash down the surface with a mixture of five parts water to one part bleach and dry off with a cloth. This should be repeated as necessary. You can also use an anti-fungal product and follow the manufacturer's instructions. If you live in a privately rented house, cleaning the mould is the responsibility of the tenant and not the landlord.
