How to Stop Condensation on Windows: Best UK Home Solutions
Condensation on windows is a common problem in many UK homes. You may see water drops on the inside of your glass, especially in the morning. It happens when warm air touches cold glass. You might see water drops, steam, or even mould. It can make your home feel damp. But don’t worry, there are easy ways to stop it. In this article, we’ll show you simple UK tips that explain how to stop condensation on windows.
What is window condensation?
Window condensation means that little water drops appear on your window glass. You often see this in the morning, especially in cold weather. It happens when warm, wet air inside your home touches the cold glass. Then, water in the air turns into drops. This is called condensation inside the window. It can make your windows wet, and if it happens a lot, it can cause damp walls or black mould.
Condensation is more common in winter because the windows get very cold. Homes with poor air flow or old windows may have it more often. If your windows mist up every day, it could mean your home has too much moisture in the air.
Over time, this can damage walls, window frames, and paint. It’s important to notice these signs early, so you can stop the problem before it gets worse.

What Causes Condensation on Windows?
Here are some causes of condensation on on window:
Cold Weather Outside
When it’s cold outside, your windows become cold too. Inside your home, the air is warm and has water in it. When this warm air touches the cold window, it turns into little water drops. This is called a condensation problem. It happens more in winter when the inside of your home is warm and the outside is very cold.
No Fresh Air in the Room
If you don’t open your windows or use a fan, the air inside stays still. Over time, water in the air builds up. This extra moisture has nowhere to go, so it sticks to cold windows and makes them wet. Homes with poor air flow get condensation on their windows more often. Opening windows for a few minutes each day helps let the wet air out and brings in dry, fresh air.
Hot Showers or Baths
When you take a hot shower or bath, steam fills the room. This steam is warm, wet air. If your bathroom window is closed or there’s no fan, the steam hits the cold surfaces of windows and mirrors. Then, water drops form. This is very common in winter.
If not fixed, it can cause black mould on walls and tiles, which is bad for your health.
Cooking Without a Fan
Boiling water, making soup, or frying food makes steam. If you cook with no fan or forget the kitchen window, the steam spreads into the room. It finds the cold glass and turns into drops. Over time, this can also lead to mould around the windows.
Keeping the kitchen door shut and using an extractor fan while cooking can help stop steam from spreading.
Drying Clothes Indoors
When you hang wet clothes inside your home, they slowly release water into the air. You may not see it, but it makes the air wet. This causes condensation inside windows, especially if the room is small and the windows are closed. Using a dryer or drying clothes outside can help.
Why Do I Keep Getting Condensation on My Windows?
Condensation happens when warm, wet air touches cold window glass. This makes water drops appear. This is called condensation forming. You may see it in the morning or when the weather is cold outside.
It happens more if you do things like cook, shower, or dry clothes inside your home. These things add water to the air. If the air can’t escape, it turns into water on your windows.
You keep getting condensation because there is too much water in the air and not enough fresh air moving around. To prevent condensation, try to open your windows each day, even for a short time. You can also use a fan or a dehumidifier, which helps take water out of the air.

How Humidity Causes Window Condensation
Humidity means how much water is in the air around you. When your home has high humidity, the air is full of moisture. This often happens after cooking, showering, or drying clothes indoors.
The warm, damp air moves around your rooms. When it touches a cold surface like window glass, it cools down fast. The water in the air then turns into drops on the glass. This is called condensation.
If there is too much water in the air, your windows can stay wet every day. To stop this, keep the air dry. You can open windows, turn on a fan, or use a dehumidifier to take water out of the air.
How to Stop Condensation on Windows: Easy Tips That Work
Here are the tips to prevent window condensation and keep your home dry and healthy.
1. Open Windows Every Day
Fresh air is very important. When you open your windows, even for 10 to 15 minutes, it helps the wet air go outside. This is one of the best ways to reduce condensation, especially after cooking, showering, or drying clothes.
2. Use an Extractor Fan in Bathrooms and Kitchens
Extractor fans help pull out steam and damp air. Always turn them on when you cook or take a shower. Leave them running for 15–20 minutes after you’re done. This stops wet air from staying inside and helps reduce condensation and mould on windows.
3. Dry Your Clothes Outside
Wet clothes add lots of moisture to the air. If you dry clothes inside, the room gets full of damp air. This damp air has nowhere to go, so it sticks to cold windows and walls. This causes condensation to form and can lead to mould or damp patches. The best way to stop this is to dry clothes outside on a line or use a tumble dryer.
4. Use a Dehumidifier
A dehumidifier is a small machine that pulls water out of the air. It’s very useful in winter or in rooms that always feel damp. It helps reduce condensation and makes the room feel warmer and fresher.
5. Wipe Wet Windows in the Morning
In the morning, check your windows. If they are wet, wipe them with a dry cloth or towel. This removes extra water and stops it from wetting the walls or window frames, which can cause mould.
6. Put Lids on Pots When Cooking
Steam from boiling water adds moisture to your kitchen. When you cover pots with lids, it keeps the steam inside. This simple tip can reduce condensation in the kitchen, especially if your windows are close to your cooker.
7. Keep Kitchen and Bathroom Doors Closed
After cooking or showering, shut the door to stop steam from moving into other rooms. This keeps the damp air in one place and stops condensation from forming on windows in bedrooms and other areas.
8. Open Curtains During the Day
Letting sunlight in the home helps keep your windows warm and dry. When the curtains are closed all day, the windows stay colder. Cold windows attract water. So, opening your curtains during daylight helps reduce condensation.
9. Leave Space Behind Furniture
Don’t push beds, wardrobes, or sofas right against the wall. Leave a small gap. This lets air move around the room. When air can’t move, it becomes damp and may lead to condensation forming on nearby windows.
10. Keep Your Rooms Warm
Very cold rooms get more condensation. Try to keep your heating at a steady level. When temperatures change quickly, more water forms in the air.
11. Use Double-Glazed Windows
If your windows have only one layer of glass, they get cold fast. Double-glazed windows are warmer inside, so they don’t make as much condensation. They also help save energy and keep your home warmer.
12. Seal Gaps Around Windows
Check the edges of your windows. If you feel cold air coming in, there may be small gaps. These let in cold air, which makes windows colder and causes more condensation to form. Seal the gaps with window sealant.
13. Keep Air Vents Clear and Open
Some homes have small vents in walls or windows. These help move air in and out. Never cover them. Good airflow is very important to keep your home dry and reduce condensation.
14. Use Trickle Vents
Modern windows often have small vents at the top called trickle vents. These vents let in a little bit of fresh air all day, even when the window is shut. This helps damp air escape without making your room cold. You don’t need to open the whole window, which is helpful in winter.
15. Keep Houseplants in One Area
Houseplants look nice, but they also give off moisture into the air. If you have many plants in different rooms, they can make the air more humid and lead to condensation. Try to keep your plants in one room that has good airflow, like near a window you can open.
One effective long-term fix for condensation is improving your wall insulation. But how long does insulation last, and when should it be replaced? Find out in our Cavity Wall Insulation Guide.
