A common issue is misting between the glass panes in a double-glazed window. This happens when the air warms up faster than the glass and gets to its dew point causing moisture to form on the bars that surround the window. This moisture can then leak out of the window, causing fogging or misty effects. The moisture can also make the glass foggy, which can hinder the view and decrease the effectiveness of the windows.
The reason for this issue occurs is because of a leak in the seal between the two glass panes of the double glazing. This issue can be caused by a variety of factors like the age of the windows and how they were originally installed. Sealants are not designed to last forever, and will wear down over time, allowing air or gas (in the case of gas filled units) to leak out, and allow water vapour to enter.
As the winter approaches it is essential to fix any problems with your double-glazed windows before the cold weather begins to set in.

Begin by carefully removing the top glass from the frame. Place the bottom glass pane on your workbench and scrub it clean with glass cleaner that you bought or kitchen paper.

Recommendations

A good guideline is that if you notice that there is a mist between the panes of your double-glazing, it is likely to need replacing. This will resolve the problem and provide you with peace of mind that your new double glazing is of a high quality and with a manufacturer's warranty.
It's not unreasonable in the short-term to try a quick solution such as drilling a small hole in the glass and blowing warm air through to eliminate the condensation. It's important to understand that this is only a way to mask the problem and not fix it. The condensation will come back because the seal is broken.
If you're looking to fix the issue but do not have a lot of money to invest, we suggest using a desiccant. They can be purchased from your local hardware store and simply put into the sealed unit to remove moisture and stop condensation developing. However, we do not recommend this for the long term, as moisture could seep into the frame and cause problems such as damp, mildew, or rot.
Window condensation can cause a lot of stress for homeowners, as they reduce the amount of light entering your home, causing huge energy losses. In addition, if the windows are made of timber, they could also be vulnerable to issues such as damp and rotting if not properly maintained.

Regular maintenance, such as cleaning your windows and caulking the frames can increase the lifespan of your windows. This will also prevent condensation. Installing exhaust fans or vents can also help circulate air and reduce the risk of condensation and humidity between your windows.
Replacing your double-glazed units with a brand new, mist-free window will significantly improve the appearance of your house and will also provide increased energy efficiency which will benefit you both in terms of comfort as well as lower heating costs.
