10 Things We Are Hating About Misty Window
What Causes a Misty Window?

When windows in your house or apartment start to fog up, it can cause a lot frustration. It's actually quite simple to fix and prevent when you understand the root of the problem.

Many people suggest using dehumidifiers to remove the moisture. However this does not address the root cause of the issue that is seal failure.

Moisture Buildup

The most common cause for foggy or misty windows is condensation, especially in older homes with single- or double-glazed window frames. These windows were designed to keep warm air inside your home, and prevent cold air from getting in but they can cause condensation and moisture accumulation. If not taken care of, this can lead to damage to the glazed or glass surface of your window, which can result in a more costly repair or replacement of the window.

The accumulation of water on windows is typically caused by the collision of cold and warm air. This is more common in homes that have high humidity levels. However, misted double glazing replacement glass can occur even if the window seal is damaged or defective.

Everyday life produces a surprising amount of indoor moisture, each moment you boil water or prepare meals adding four or five pints to the air. Every shower, tumble dryer use and watering of your house plants contributes to more. Even breathing in and exhaling produces some water vapour. The air in your home is filled with water vapour and as it cools it will melt any surface it comes into contact with, including your windows.

If you have a triple- or double-paned window and notice condensation between the panes, it is likely that the seal has been damaged or broken. In most cases, there is a spacer held between two panes of glass and is designed to absorb any moisture that might be in the gap. This spacer is normally invisible, but it can be identified by gently shining a light at the window to check for any streaks or dark spots.

If the spacer fails, it is not unusual to discover black mould in the area, which is both unsightly and a potential health hazard. The mould can be difficult to get rid of and could cause a discoloration of plaster walls surrounding the affected window. If not treated, it could cause irritations to the skin, respiratory issues and asthma.

Condensation

Condensation occurs when moist, warm air comes in contact with a surface that is cooler like windows. The change in temperature causes the water in the air to change into a gas (water vapor) into liquid (water droplets). It is normal to experience condensation, but if it occurs frequently it could be problems with your air conditioning and indoor humidity or window quality. You can fix the issue by changing these factors.

Moisture buildup is the most common reason for foggy windows. If your windows have double or single glazing, and a sturdy seal, then water from the inside is less likely to escape and cause condensation. If the windows are old or have seals that are damaged or if you live in an area that is humid the moisture is more likely to escape through the gaps.

If the moisture is not removed, it could build up on the glass, forming a layer of white fog on the window. Fogged windows are not only ugly, but they can also trigger many issues in the home. The moisture can cause damp spots that can become breeding grounds for mould and may discolor surfaces like wallpaper or paint. It can also cause conditions like asthma respiratory infections, allergies and asthma.

It is crucial to take care of damp as soon as it begins to appear, because if left untreated it could cause structural damage to your home. It could also trigger the development of fungal and bacterial infections. It may even cause the destruction of wooden structures, such as floors and roofs.

You may have heard suggestions for defogging spray or wiping the windows with shaving cream but these are just temporary solutions. These solutions are designed to eliminate the moisture, but not solve the problem that is causing the condensation.

Heat Loss

Windows are more than just windows to let in light and connect with the outside. They also act as insulation for our homes. Over time, they can lose their insulating properties if their seals are damaged. This can result in the development of windows that are smudgey, which is not just ugly, but also cause an energy loss that is significant.

When the glass in the double-glazed window turns blurred, it is a sign that the seals between the panes have failed and moisture is being allowed to enter the space. This can be caused by a variety of factors such as sunlight, water, fluctuating temperatures, or even barometric pressure. As time passes, the seals will deteriorate. This is why you must replace your double-glazed windows as soon as they begin to fog.

As the warm air inside your home reaches the cold glass surface and condenses, it can result in fog or mist that forms on the windows. This is because the dew point is below the glass's cold surface. The dew point is the temperature at which the moisture in the air transforms into water vapour. Therefore the water vapour that is released from the warmer air is unable to go and so it will fall onto the colder surface of your double-glazed window where it will be held until it is evaporated.

There are a variety of ways to stop these issues from occurring such as exhaust fans that are designed to let the moisture out. This can lower the humidity levels in your home which is a major cause of misty windows. Also, removing all plants from your windowsill and opening the windows as much as possible will also help in balancing humidity levels. If the problem continues however, it might be advisable to invest in a good quality dehumidifier which can help maintain a low humidity and prevent fog or mist from forming on your windows.

If you're looking to replace your windows, it's also worth investing in double-glazed windows that are energy efficient. According to the Energy Saving Trust old single-glazed Windows account for around 25% of the heat loss in homes. Upgrading your current windows to energy-efficient PVC double-glazed windows can cut the loss by up to 75%.

Damage to the Glass

Damaged window glass is not only a visual affront it can also be an issue and draw unwanted intruders. It is important to know the root cause of these issues so you can take the necessary steps to prevent them from recurring.


Misty windows are a typical issue, particularly in winter. Moisture buildup is primarily caused by poor single or double glazing, which allows moisture to seep through the frame and glass. This is caused by a variety of factors, such as high indoor humidity and temperature variations.

Good windows come with frames and glass that is insulated and designed for better energy efficiency. They usually have double-panes. argon gas, and a seal that helps to reduce heat loss. This could save money in the long run on energy bills and make a house more comfortable. However, older windows with single panes could have a variety of problems that affect their efficiency and may require replacement to reduce energy costs and improve the comfort of your home.

Many people with foggy windows attempt to resolve the issue themselves. It is typical to suggest installing a dehumidifier near the window to try to remove excess moisture. This isn't necessarily an ideal solution but it will not solve the root of the issue, which is that the window seals have failed.

An effective method to clean windows is to use a mixture of water and vinegar. This solution can be sprayed over the glass or wiped with a microfibre towel or squeegee. After the surface is dried it can be buffed and polished to eliminate any streaks.

If your windows have damaged seals, you need to get them repaired or replaced as soon as possible to improve the insulation of your home and prevent costly repairs in the future. Contact the experts at Portage Glass & Mirror to perform a thorough examination of your windows and suggest the best course of action that will restore their appearance and function.
