What causes condensation on windows and how do I prevent it?
CONDENSATION is a common problem for many home owners during the colder months.
Not only do foggy windows make it difficult to see outside, the dampness could cause mould, which is very damaging to you and your families’ health.
So what causes condensation and how do you overcome the pesky problem of condensation and mould this festive season?
What causes condensation?
Condensation happens when warm air catches on to a cold surface.
You may see your breath when you breathe out outdoors, especially when it’s cold, and things like cooking, washing, or having a shower can also cause the fog to form.
A common example at home is when steam rises from a hot bath, it can hit your cold bathroom mirror, causing condensation.
The moist water vapour in the air then turns into water droplets which you can see on the mirror.
But as we turn our radiators back on for the winter, the warm air can cause condensation to form on your windows too.
How to banish the fog from your home
You can stop condensation at home by keeping your house well ventilated, so simply having a daily routine of opening windows, doors and letting air in can really help.
Opening your windows may not be as tempting in winter as we naturally want to keep the cold out, but doing this for short periods of time each day will allow the warm moisture to escape so it’s important to do.
Not ventilating your house will trap the moist air and will fog up your windows.
Keep your home at a comfortable temperature because one constant temperature reduces the chances of condensation.
Putting on the extractor fan while you cook can also halt any dinner-time fog from forming.
If condensation is already an issue inside your house, there are some simple ways to get rid of it.
Use a sponge or a squeegee to wipe down places that have the unwanted water droplets, then dry it off with a clean towel.
What the experts say
Property preserving experts, Peter Cox have suggested a few tips to prevent condensation build up in your home.
- Do not have furniture pressing up against your walls – allow some space for air to flow
- Do not block airways, air vents or chimney
- Install an extractor fan
- Dry your clothes outside any chance you get
- Close bathroom doors
- Use pan lids when cooking
Cheap condensation hacks
1. Use Salt or Cat Litter
– Place bowls of salt or silica-based cat litter in areas prone to dampness. These materials are excellent at absorbing moisture from the air.
2. DIY Dehumidifier
– Create a simple dehumidifier using a plastic container with a lid. Punch holes in the lid, fill the container with silica gel or activated charcoal, and place it in humid areas.
3. Ventilate When Cooking and Showering
– Open windows or use extractor fans when cooking or showering to let moisture escape. Even a small gap can make a significant difference.
4. Wipe Down Windows
– Regularly wipe down windows and other cold surfaces with a dry cloth to remove condensation. This prevents moisture from accumulating and causing mould.
5. Use Houseplants
– Certain houseplants, like peace lilies and spider plants, can help absorb moisture from the air. They also improve indoor air quality.
6. Keep Lids on Pots
– When cooking, keep lids on pots and pans to reduce the amount of steam released into the air.
7. Dry Clothes Outside
– Whenever possible, dry clothes outside or in a well-ventilated area instead of using indoor drying racks.
8. Open Curtains and Blinds
– During the day, open curtains and blinds to allow sunlight to warm up windows and reduce condensation. Sunlight also helps to reduce mould growth.
9. Use Towels Wisely
– Keep towels and other fabrics away from walls and windows to prevent them from absorbing moisture and becoming damp.
10. Seal Cracks and Gaps
– Use inexpensive weatherstripping or caulk to seal any cracks or gaps around windows and doors. This helps to keep cold air out and warm air in, reducing condensation.
