In this article, we’ll reveal what causes condensation on windows, what to do about window condensation, as well as unveiling the very best remedy for condensation on windows.
What Causes Window Condensation?

Depending on the nature of the problem, window replacement may be the best option, especially if they are old. However, applying a new sealant is a more affordable option and adequate if only the seal is damaged.
On the window sill
Condensation on the window sill appears as small pools of water either on the sill or at the bottom of the window.
The causes of condensation on window sills
This may be due to condensation dripping down the internal window onto the sill, especially if you have a lot of water gathering on your windows. You’re more likely to notice this in winter when the weather is colder and you’re cranking the heating up inside your home.
The best remedy for condensation on window sills
Try opening your windows slightly when cooking or having a shower. This will help any excess moisture in the air to escape outside. Alternatively, try using a moisture trap on your window to absorb water. Wiping down your windows when you notice condensation can help to remove water. Either use a squeegee or a cloth to effectively wipe your internal glass windows.
Is Window Condensation A Problem?
How extensive an issue is window condensation? While it may seem like a relatively minor issue, condensation on your windows could become a serious problem if it’s not tackled. Here are just a few challenges that severe damp can pose to both people and buildings:
- Serious damp on the inside dry walls next to your windows, including visible water damage, stains etc
- Mould and mildew on your internal window frames and sills which are visible as black or brown dots. This can cause structural damage, including rotting wood
- The expense of replacing windows, fixing wall and structural damage
caused by damp
- Health issues, such as sinus problems, rashes, throat irritation, eye irritation, coughing, wheezing, lung infection, respiratory illness,
development of asthma in children
- Using energy unnecessarily as the heat from the sun is being used
to evaporate condensation rather than warm up the home
How To Reduce Window Condensation
Now you’re aware of what causes condensation on windows, it’s time to look at what to do about window condensation. Here are some handy tips on reducing window condensation within your home, including the approximate costs and whether this is a temporary or long-term solution.
Run a bathroom fan while showering
Cost involved: Around £300 for the cost of installation. If you’re installing the fan yourself, you can expect to pay up to £100 depending on the fan you purchase.
Use pan lids when cooking
Cost involved: Up to £400 for the kitchen hood, including installation. This cost will vary depending on the model used and if you install it yourself. The cost of pan lids is significantly cheaper at around £5 upwards for a pan and lid.
Buy a dehumidifier
Cost involved: Around £50 upwards. There is also the cost of running a dehumidifier to contemplate. This can be around £10 per week per dehumidifier.
Close the doors in your home
Cost involved: Free.
Avoid drying wet clothes inside
Cost involved: Free to dry clothes outside. A tumble dryer can cost around £200 upwards plus running costs. Depending on the brand of machine, it can cost on average £20 per year for 60 minutes usage per week.
Use VOC free paint in your home
Cost involved: While they can be more expensive than traditional paint, VOC paints tend to be more eco-friendly. Depending on the volume purchased, a small pot starts from around £5.
Choose the right houseplants
Cost involved: From around £3 upwards.
Check for water leaks

Cover up your fish tank
Fish tanks and indoor aquariums can enhance air moisture if they’re not correctly covered. You’ll also prevent any fish from jumping out! A hood or cover isn’t overly costly, although it does depend on the size of your tank.
Cost involved: Around £20 – 30.
Ensure your heating is adequate
Good heating within your property will prevent condensation occurring, as well as keeping surfaces warmer. Adequate central heating will also prevent temperatures from fluctuating to prevent damp from forming on your walls.
Cost involved: Expensive. The cost of installing energy-efficient central heating in a two-bedroom home is around £2000. However, this permanent investment will significantly reduce window condensation and damp within your home.
Install the right insulation
Effective insulation like double-glazed windows and loft and wall insulation keeps heat within your home, prevents window condensation forming between panes of glass and stops heat from escaping. This permanent home solution for condensation and damp also keeps surface temperatures at a higher level.
Cost involved: Expensive. Installing new double-glazed windows for a 3 bedroom semi-detached house is on average £5000. The cost of loft insulation for the same size house is around £300, while cavity wall insulation is around £500.
Monitor moisture levels
Cost involved: Around £20 – 25.
Check the exterior of your property
Check your exteriors for any cracks or damage to the roof, walls or windows that could be letting moisture creep in your home.
Cost involved: Depends on the area that needs fixing or replacing. Wall cracks may need extensive work which can cost up to £5000. Sealing windows or doors costs around £45, while fixing a roof repair is £150+.
