Avoiding condensation
There are a number of steps you can take to avoid condensation.
Heating
Homes should have permanently fixed heaters rather than portable heaters. They should be maintained in proper working order. The heating should be sufficient to properly heat the whole home. You should be able to control the heating, for example, by a room thermostat or thermostatic radiator valves.
Constant low level heating rather than short bursts of high heat is better to help prevent condensation.
Insulation
Insulation and draught exclusion to windows, doors and gaps helps to keep the home warm. It also cuts fuel costs and reduces condensation forming. Homes should (where appropriate) have the specified amount of loft insulation in accordance with building regulations. They should also have cavity or solid wall insulation. Some older forms of cavity wall insulation may not be effective and could even lead to damp problems by bridging the cavity.
There are grants available for insulation. Visit the Action Surrey website (external link) for more information.
Ventilation
This is important to help remove moist air and ensure good air flow in the home. Bathrooms and kitchens where moisture is generated by bathing and cooking should have extractor fans. Ideally these should be humidistat which activate when moisture in the air reaches a certain level. If you have them, ensure they are working properly. A good test is to see if a piece of paper 'sticks' to the vent when it is on. This means it is actively drawing air outwards. They will need cleaning and servicing from time to time.
Windows should be regularly opened to ventilate. Most modern double-glazed units are able to be locked in a slightly open position for ventilation whilst maintaining security. Some windows have trickle vents which can be left open.
Keep furniture away from walls and don't overfill cupboards. Adding vents to built-in cupboards and wardrobes will help air circulation.
Ways to reduce moisture generation
- put lids on pans when cooking
- ventilate the kitchen during and after cooking
- close the door to avoid moist air travelling around
- make sure vented tumble dryers are properly vented to the outside.
- minimise the drying of clothes inside
- when drying clothes inside have heating and ventilation in the room and close the door to avoid the moist air travelling
- avoid the use of calor gas or paraffin heaters as they generate large volumes of moisture
- close doors to bathrooms when running or baths or showers and ventilate well afterwards
