When water condenses on surfaces in your home, it can lead to damp spots and mould, and make your home an unhealthy place to live. Follow the advice and tips below to keep your home a nice, safe place to live.
If you are a council tenant and condensation has formed in the space between your windows panes, report it to us.
Mears can then plan a visit with you to inspect the unit, measure it up and organise a replacement.
There is always some moisture in the air, even if you cannot see it.
When moist air hits a cold surface, it cannot hold it and tiny droplets of water will form on that surface (you can see this when the mirror mists up after a bath). This is condensation, which:
- occurs mainly during cold weather
- appears on cold surfaces and in places where there is little movement and circulation of air
Condensation is common in a few specific areas in a home. Look out for condensation and mould:
- in room corners
- on or near windows
- in or behind wardrobes and cupboards
- in rarely used rooms
Condensation can lead to mould, which can lead to respiratory problems, such as asthma, and worsen existing respiratory problems.
Produce less moisture
More moisture in the air makes it easier for it to escape by forming condensation. Keep moisture low, and:
- cover pans when cooking to prevent steam from escaping
- dry washing outdoors whenever possible, or over the bath with the door closed and the window open
- vent any tumble dryers outside, or consider buying a self-condensing type.
- Keep doors closed when having a bath or shower to prevent moisture reaching other rooms.
Did you know? Drying clothes in an un-vented tumble dryer produces a massive 10 pints of moisture. A bath can create 2 pints of moisture.
Ventilate your home
Ventilation improves the movement of air and circulation in your home, making it more difficult for condensation to form. Improve your home's ventilation by:
- keeping a small window ajar, or a trickle ventilator open
- ventilating your kitchen and bathroom when in use by opening windows or using a humidistat-controlled electric fan - these automatically start when the air becomes moist, and are cheap to run
- ventilating cupboards and wardrobes, and positioning them (and other furniture) against internal walls where possible
Insulate and draught proofing
Condensation forms in cold spots. Insulating your loft, draught proofing windows and doors, and installing cavity wall insulation will help to eliminate cold spots in your home (as well as making it cheaper to keep your home warm).
Heating more efficiently
Try to keep rooms in your home heated equally - it is better to heat your whole home to a lower temperature, rather than heat one room to a high temperature.
A difference in temperature in your home can cause condensation to form in the colder rooms. A spare bedroom might not normally be heated because it's not in regular use; condensation will be more likely to form in this room, because of the lack of heat.
If you take care to prevent condensation forming in your home, mould should not appear. However, if it does, the mould can be killed and removed by wiping down the walls and window frames with a fungicidal wash.
When using a fungicidal wash, take care to follow its instructions precisely. Avoid disturbing mould by brushing or vacuum cleaning it, as this can increase the risk of respiratory problems.
After treatment, redecorate using a good quality fungicidal paint. This will help prevent mould occurring there in the future. This paint will not be effective if it is not overlaid with wallpaper.
- You can stop condensation forming on mirrors or windows by rubbing a small spot of washing up liquid over the surface with a cloth. Try this at home or in the car - taxi drivers have been doing this for years.
- You can also prevent condensation forming on windows by cutting a potato in half and rubbing it across the window, buffing with a cloth afterwards.
If you are a council tenant and have followed all of the above steps, but are still having issues with damp or mould, report it to us.
You can also send photos of the affected area to Operations@scambs.gov.uk. These can then be assessed to determine whether a surveyor needs to come out to inspect the problem.
