Preventing Bedroom Window Condensation: Tips For A Clear View

Condensation on bedroom windows is a common problem, especially in the winter months. It occurs when warm air hits a cold surface, such as a window, and releases moisture. While it may seem harmless, if left untreated, condensation can cause mould to grow, which can be detrimental to your health and cause damage to your home. To prevent condensation on your bedroom windows, you can try a number of things, including improving ventilation, investing in a dehumidifier, and avoiding drying clothes indoors.

How to Stop Condensation on Windows in the Bedroom

Open windows and doors

Opening windows and doors is a simple yet effective way to prevent condensation in your bedroom. By doing this, you allow the humid air to escape outside and prevent it from settling on your windows.

It is recommended to open windows for at least 20 minutes a day, especially in small, open-plan apartments or homes without efficient extractor fans or air bricks. This simple action can drastically reduce condensation and dampness. If you are worried about security or the cold, you can try keeping windows open for shorter periods, such as just at night when the outside air is drier, or using the night vent facility on your windows.

Additionally, keeping internal doors open, especially the bedroom door, is important. This allows for better air circulation and prevents excess moisture from becoming trapped in one room. Keeping the bedroom door open is especially important if there are multiple people sleeping in the room, as the breath of multiple people will increase humidity.

Opening windows and doors is a great way to improve ventilation and reduce condensation. However, this may not be a practical solution for everyone, especially during colder months. Therefore, it is good to combine this method with other strategies, such as using a dehumidifier or moisture eliminator, keeping the heating on low, or drying clothes outside or more effectively indoors.

Use a dehumidifier

Dehumidifiers are an excellent way to reduce condensation in your bedroom. They work by drawing warm air currents into their coils via a fan. The warm air contracts as it is fed through the refrigerated coils of the machine, and the condensation is left inside the dehumidifier. This condensation will then need to be emptied from the dehumidifier.

Dehumidifiers come in a variety of price points, and there are even disposable options available. You can buy a disposable dehumidifier for as little as £1.49 from B&M. These can be placed near affected areas of the home and disposed of once full.

If you are able to invest in a higher-quality, reusable dehumidifier, there are some great options on the market that absorb all the moisture in the air. Crane offers a 4-pint dehumidifier for $87.99, which is lightweight and suitable for smaller spaces. If you are looking for something with a larger capacity, the Frigidaire FFAD2233W1 Dehumidifier has a capacity of 22 pints and is available for $199.

While a dehumidifier is an effective way to reduce condensation, it does require some maintenance. Dehumidifiers need to be emptied from time to time, and you may not want one running in your bedroom at night. However, you can set a timer for your dehumidifier to turn on after you wake up and switch off an hour or so later. This will help stop condensation from becoming a problem without running throughout the night.

Dehumidifiers use very little energy to run, so you won't see a significant increase in your energy bills. They are a great solution for those living in older, more traditional homes that are more prone to dampness and condensation.

Dry clothes outside

Drying clothes inside the house is one of the main causes of condensation, which can lead to mould and damp. This is especially true in the colder months when drying clothes outdoors is not an option.

If possible, dry your clothes outside, as they release moisture into the air when dried indoors, increasing the humidity and causing condensation. If you are unable to dry your clothes outside, there are a few alternative solutions to prevent condensation from forming.

Firstly, ensure that you dry your clothes in a well-ventilated room, preferably with plenty of windows to allow sunlight to aid the drying process. Keep the windows open to allow the moist air to escape. If you are drying clothes in a room without windows, such as a bathroom, ensure that the windowless room has good ventilation and that the door remains closed to prevent moisture from spreading throughout the house.

Secondly, consider investing in a tumble dryer, which is an effective way to dry clothes without introducing moisture into the air. However, tumble dryers require ample space and can consume a lot of electricity.

Finally, if you are drying clothes on a radiator, consider adding an extra spin cycle to reduce excess water before hanging them up. This will help minimise the amount of moisture released into the air.

Keep curtains open

Keeping your curtains open can be an effective way to reduce condensation on your bedroom windows. Condensation occurs when warm, moisture-rich air comes into contact with a colder surface, such as a window pane. This is more likely to happen when windows are colder than the room's ambient temperature. Closing curtains can prevent the window from being warmed by the central heating, making the glass colder and more prone to condensation.

Keeping your curtains open at night helps maintain the temperature of the window pane by exposing it to the room's warmer air. This reduces the likelihood of condensation forming. If keeping curtains open at night is impractical, switching to thinner curtains can also make a difference.

Additionally, closing curtains can sometimes trap moist air against windows, exacerbating condensation issues. Pulling back the curtains can improve air circulation and prevent condensation from spiralling out of control.

To further reduce condensation, ensure your bedroom is well-ventilated. Open a window slightly to release moisture and prevent it from spreading throughout your home. It is particularly important to ventilate the room if you have been cooking, showering, or drying clothes indoors, as these activities increase moisture levels in the air.

Use anti-condensation paint

Anti-condensation paint is a great way to prevent condensation and mould from building up on your windows and walls. This paint adds an extra layer of insulation to your walls, keeping the surface temperature above the dew point and helping to prevent condensation from forming. Not only does it reduce condensation, but it also absorbs moisture in the air, helping to reduce droplet formation. This type of paint is low maintenance and cost-effective, and once applied, it can last for years.

Step 1: Identify the Cause of Condensation

Before applying anti-condensation paint, it is important to identify the cause of condensation in your bedroom. Condensation occurs when warm, moist air comes into contact with a cold surface, such as a window. This is common in bedrooms, especially during the colder months when the temperature difference between the inside and outside of the window is greater.

Step 2: Prepare the Surface

To ensure the anti-condensation paint adheres properly and provides effective protection, it is important to prepare the surface before painting. Here are the steps to prepare the surface:

• Remove any existing mould: If there is mould present on the surface, use a mould killer or remover to eliminate it completely. Do not sand or scrape the mould, as this can spread the mould spores.
• Repair any damage: If there are any holes, cracks, or other damage to the surface, repair them before painting.
• Clean the surface: Ensure the surface is clean and dry before painting. Remove any dirt, dust, or grease that may interfere with the paint adhesion.
• Sand the surface: Lightly sand the surface to create a smooth finish and improve paint adhesion.
• Prime the surface: Depending on the type of surface and the paint you are using, you may need to apply a primer coat before painting. Follow the instructions on the paint can or consult a professional for advice.

Step 3: Choose the Right Paint

When choosing anti-condensation paint, consider the following factors:

• Type of paint: There are different types of anti-condensation paints available, including water-based and oil-based paints. Water-based paints are generally easier to work with, dry faster, and have lower odour. Oil-based paints provide a more durable finish but take longer to dry and have a stronger odour.
• Colour and finish: Anti-condensation paints are available in a variety of colours and finishes, including white, magnolia, and pale slate. Choose a colour and finish that matches your bedroom décor and preferences.
• Coverage: Consider the coverage of the paint, as some paints may require multiple coats for effective protection. Calculate the area you need to paint and check the coverage specifications on the paint can to determine how much paint you will need.
• Brand and price: There are several brands of anti-condensation paint available, offering a range of prices. Consider your budget and read reviews to choose a reputable brand that offers good value for money.

Step 4: Apply the Paint

Once you have selected the appropriate anti-condensation paint, follow these steps to apply it effectively:

• Stir the paint: Before using the paint, thoroughly stir it to ensure the ingredients are well mixed and the consistency is smooth.
• Prepare your tools: Gather your painting tools, such as brushes, rollers, and trays. Choose the appropriate tools based on the surface you are painting and your personal preference.
• Protect the surrounding area: Use drop cloths or plastic sheeting to protect the surrounding area, including floors, furniture, and any adjacent surfaces that you do not want to get paint on.
• Apply the first coat: Pour the paint into a tray and dip your brush or roller into the paint. Apply the paint to the surface, ensuring you achieve a consistent and even coverage. Follow the instructions on the paint can for drying times and recommended application techniques.
• Apply the second coat: Allow the first coat of paint to dry completely according to the manufacturer's instructions. Once dry, apply a second coat of paint to ensure thorough coverage and protection.
• Clean your tools: After you have finished painting, clean your brushes, rollers, and trays with warm soapy water or as recommended by the paint manufacturer.

Step 5: Maintain Good Ventilation

Even after applying anti-condensation paint, it is important to maintain good ventilation in your bedroom to prevent condensation from building up. Open your windows regularly, especially after showering or cooking, to allow moist air to escape. Consider using extractor fans or dehumidifiers to help remove excess moisture from the air.

By following these steps and using anti-condensation paint, you can effectively reduce condensation on your bedroom windows and create a more comfortable and healthy environment in your home.
