Mould and condensation

Combatting condensation

If you’ve noticed damp in your home or found patches of mould on your walls, furnishings, or clothes, then condensation might be to blame. We’ve put together some information to help you combat condensation and keep you and your family happy and healthy.

Why do you get condensation?

Air can only hold a certain amount of water vapour, and the warmer it is, the more it can hold. If the air is cooled by contact with a cold surface, such as a mirror, window or a wall, the vapour will turn into droplets of condensation. So, generally, the warmer you keep your home, the less likely you are to get condensation.

When does condensation become a problem?

Every home gets condensation from time to time. Usually, it occurs in the bathroom after bath or shower, in the kitchen when things are bubbling away on the hob, and anywhere you dry your clothes. It’s also normal to find your bedroom windows misted in the morning following a cold, wintry night. None of these things are cause for concern, but if you find that your home never seems to be free from condensation, then read on.

How do you know if it is condensation?

Condensation is often found in corners, cupboards and under work surfaces, wherever there is little or no air movement. If you’re not sure what is causing damp in your home, start by checking pipes, overflows and under sinks to see if there are any obvious leaks. You should also look outside to see if there are any slates missing from the roof, cracked gutters or rainwater pipes.

If you live in a new or recently modernised house or flat, it is important to remember that your home may not have dried out from the water remaining after building work, and this can take around 18 months to finish.


Top tips to beat condensation

1. Doors

Keep kitchen and bathroom doors shut, particularly when cooking, washing and bathing. This will help to prevent water vapour spreading through the house and stop the condensation from reaching other rooms.

2. Cupboards and wardrobes

Never overfill cupboards and wardrobes, always making sure air can circulate freely through ventilators in doors and around space at the back of the shelves.

3. Kettles and pans

Don’t allow kettles and pans to boil for any longer than you need, as this increases the amount of water moisture in the air. Always use extractor fans where possible and open windows or trickle vents if you can.

4. Drying clothes

Try to avoid drying clothes indoors, especially on radiators, as this will increase condensation in your home. If you must dry clothes inside, make sure to open a window so that the room is property ventilated. Tumble dryers must always be vented outside.

5. Mould growth

If you spot mould on your walls or ceiling, you can remove it by cleaning it off with specialist products that are available from most supermarkets. Always follow the manufacturer’s instructions carefully when using these products. If you notice the mould comes back, or spreads, please don’t hesitate to give us a call.
