The four main factors that cause condensation:
What is condensation?
Condensation occurs when warm, moist air meets a cold surface.
There is always some moisture in the air, even if it cannot be seen. When air cools it cannot hold all the moisture and tiny drops of water appear. If moist air cannot escape through an open window or air vent, it will move around your home until it finds a cold spot such as a window, mirror or tiled wall, where it will become condensation. This may lead to mould growth.
Condensation occurs in cold weather, even if the weather is dry. If there is a ‘tidemark’, this may be due to condensation or might have another cause such as water leaking into your home from a plumbing fault, loose roof tiles or even rising damp.
Problems that can be caused by excessive condensation.
Dampness caused by excessive condensation can lead to mould growth on walls and furniture, mildew on clothes and other fabrics and the rotting of wooden window frames. Damp humid conditions also provide an environment in which house dust mites can easily multiply. The presence of mould and dust mites can make existing respiratory conditions, such as asthma and bronchitis worse.
Reduce the potential for condensation by producing less moisture
Steps you can take to reduce condensation in your home:
Ventilating your home
Proper ventilation is a key step in reducing condensation in your home:
Why is too much moisture produced in your home?
Everyday activities add extra moisture to the air inside your home. Even one person asleep overnight will add half a pint of water to the air. To help illustrate how easy it is to add moisture to the air in your home it is useful to know that:
2 people at home can produce
A bath or shower
Cooking and use of a kettle
Bottled gas heater (8 hours)
Drying clothes indoors
Total moisture added in 1 day:
26 Pints or 14.8 Litres
Condensation forms more easily on cold surfaces in your home.
In many cases, surfaces can be made warmer by improving the insulation and draught-proofing. This will also help keep your whole house warmer and cut fuel bills. When the whole house is warmer, condensation becomes less likely. Loft and wall insulation are the most effective forms of insulation.
If you install draught proofing then do not:
If you believe that your home could benefit from improving the loft or wall insulation then contact your landlord.
Temperature of your home
It is better to have a medium to low level of heat throughout your home.
Warm air holds more moisture than cooler air that is more likely to deposit droplets of condensation around your home. Heating one room too much and leaving other rooms cold makes condensation worse in the unheated rooms. Therefore it is better to have a medium to low level of heat throughout your home. Keeping the heating on low all day in cold weather will help control condensation however, check on your meters to be aware of how much it is costing you to do this. Use the controls on radiators to get a little heat into every room.
Steps against condensation…
It is important to take proper steps to deal with condensation, here are some simple things you should do straight away:
Steps against mould growth…
First treat the mould already in your home, and then deal with the basic problem of condensation to stop mould reappearing.
To kill and remove mould, wipe down or spray walls and window frames with a fungicidal wash e.g. mould and mildew cleaner.
Dry clean mildewed clothes and shampoo carpets.
Do not try to remove mould by using a brush or vacuum cleaner.
After treatment, redecorate using good quality fungicidal paint or a fungicidal resistant wallpaper paste to help prevent mould recurring.
