What Causes a Misty Window?
If the windows in your home or apartment get clogged up, it can cause a lot of frustration. It's a good thing that it's easy to stop and fix if you know what causes the issue.
Many people recommend using dehumidifiers to eliminate the moisture. This does not address the cause of the problem that is a seal failure.
Moisture Buildup
Moisture is a common cause of misty windows, particularly in older homes with single or double windows with glazed frames. The windows were designed to keep cold air from entering your home, and keep heat in. However, they could cause condensation and moisture build-up. This can result in damage to the window's glazed or glass surface, which can cause a costly repair or replacement.
The buildup of moisture is usually caused by warm and cold air colliding and causing moisture to form on the window. This is more prevalent in homes with high humidity levels. However, it can occur even if the window seal is damaged or defective.
Every day, you add between four and five pints of water to the air each time you boil or cook water. Every shower, tumble dryer use and watering of the house plants adds more. Even breathing in and exhaling creates a little water vapour. The air in your house is saturated with water vapour, and as it cools it will liquify any surface comes into contact with, including your windows.
If you have a double or triple-paned window and you notice condensation in between the panes it is likely the seal has been damaged or broken. Usually, there will be a spacer held between two glass panes and it is designed to absorb any moisture that may be in the gap. This spacer is typically invisible however, you can detect it by shining a flashlight on the window and looking for streaks or dark spots.
If the spacer fails, it is not unusual to discover black mould in this area, which is both ugly and a health hazard. The mould is difficult to get rid of and can also discolor the plaster walls surrounding the affected window. If not treated, it could lead to respiratory problems as well as asthma and skin irritations.
Condensation
Condensation occurs when warm moist air comes into contact with a cooler surface like windows. The temperature changes cause the air's water to transform into a gas (water vapor) into liquid (water droplets). It is normal to experience condensation, however, if it happens frequently it could indicate problems with your air conditioning and indoor humidity or window quality. The change in these factors can help you resolve the problem and ensure that your windows are clean.
Moisture buildup is the most common reason for foggy windows. If your windows are insulated with single or double glazing and have a solid seal, any moisture that comes in from the home will not be able to pass through and cause condensation. If the windows are old or have damaged seals or if you live somewhere humid, moisture will more likely escape through the gaps.
If the moisture isn't drained it can build up on the glass causing fog to appear on the window. Fogged windows aren't just ugly, they can also trigger a host of problems in the home. The moisture can create damp spots that can become the perfect breeding ground for mould and may discolor surfaces like wallpaper or paint. It can also exacerbate existing health issues like asthma, allergies and respiratory infections.
It is crucial to deal with damp as soon as it begins to appear as if it is not dealt with it could cause structural damage to your home. It may also promote the growth of fungal and bacterial infections. It can even lead to the destruction of wooden structures such as floors and roofs.
Some have suggested using defogging cream or shaving cream to clean the windows, but these are merely temporary solutions. These are aimed at making the moisture disappear and not addressing the root cause of the condensation, which is a fault with the window seals.
Heat Loss
Windows are not just a source of light and a connection to the outside, they also provide insulation for our homes. As time passes, they may lose their insulating properties if the seals become damaged. This can lead to windows with misty appearance that are not just visually unattractive, but also contribute to a significant loss in energy.
If the glass of your double-glazed window is misted it is a sign that the seals that separate the panes have failed and moisture has been allowed to enter. This could be due to many factors, such as sunlight, water, changing temperatures, and barometric pressure. As time passes, these seals will eventually break down, which is why it is essential to have your double-glazed windows replaced immediately you notice any signs of them becoming misty.
When the warm air in your home contacts the cold glass surface and condenses, it leads to fog or mist appearing on the windows. This is because the dew point is located below the cold surface of glass. The dewpoint is the point at which the air surrounding you turns into water vapour. The water vapour in the warmer air will not have a place to go, and will fall on the colder surface on your double-glazed window. It will stay there until it is evaporated.
There are a variety of methods to prevent these issues from happening, like using exhaust fans that are designed to let moisture outside. This will help lower the humidity levels in your house which is one of the main causes of misty windows. Also, removing the plants from your window sill and opening as many windows as possible will help balance humidity levels. If the problem continues, however, it may be advisable to invest in a good quality dehumidifier. It can help keep humidity levels at a minimum and avoid fog or mist on your windows.
In addition, it's also worth investing in energy efficient double-glazed windows if you're planning to replace your current windows. According to the Energy Saving Trust, old single-glazed windows contribute around 25% of the heat lost in homes and upgrading your windows to energy efficient PVC double-glazed windows can reduce this figure by as much as 75 percent.

Damaged window glass is not just an eye-sore but also a source of irritation and attract unwanted intruders. It is important to know the root cause of these problems so you can take steps to prevent them from recurring.
Misty windows are a typical issue, particularly in winter. The reason for this is by inadequate double or single glazing, which allows moisture to seep through the glass and frame. This can be caused by various factors, such as high humidity in the indoors and temperature variations.
Good windows come with frames and insulated glass designed for better energy efficiency. They typically have double-panes, argon gas and a seal that aids in reducing heat loss. This will save you money on energy bills, and make your home more comfortable. However, windows that have single panes can be prone to a range of issues that affect their efficiency and might require replacement to cut down on the cost of energy and increase the comfort of your home.
In many instances, those who have windows that are cloudy will try to solve the issue by themselves. It is commonplace to suggest installing a dehumidifier near the window to remove any excess moisture. This isn't necessarily a bad idea but it will not solve the underlying problem which is that the window seals have failed.
A more effective way to clean windows is to make a mixture of water and vinegar. This solution can either be sprayed onto the glass or scrubbed with a microfibre towel or squeegee. After the surface has dried, it can be buffed and polished to remove any streaks.
It's important that you repair or replace the damaged seals on your windows as quickly as possible. This will improve the insulation of your home and will prevent further repairs.
