A leak in the seal is usually the reason for mist appearing between your glass windows. This issue must be addressed immediately to prevent mould or damp forming within your home.
Condensation Between the Windows
If condensation appears between your windows, this could be an indication that the sealing in the gas insulating the windows has failed. This is a serious issue that should be addressed promptly, especially in winter when the humidity levels are at their highest. It could cause damage to the sills, sealant, and even mildew or mould.
Double-glazed windows shouldn't have condensation between the panes. This could be caused by high humidity or a very cold snap. This issue is usually resolved without having to replace the entire window. A professional can drill tiny holes into the glass and then spray the inside of the window with a specific cleaning solution. The water is then removed from the window. An anti-fogger is installed to prevent the accumulation of moisture from happening again.
Condensation between windows can be caused by air leakage or other causes outside the window. If this is the case, it will likely take longer for moisture to collect in the window as the air has to be sufficiently warm for the water molecules to vaporise. In these cases it is more beneficial to replace double-glazed windows rather than attempt to repair the sealed units.
A double-glazed windows is made consisting of three or more pieces of insulated glass that are held together by a metal frame. The gap between the two windows is filled with an insulating gas, such as Krypton or argon, and then sealed. The seal blocks the insulating gases from escaping and also prevents moisture and air from entering the gap.
As windows get older, the seals weaken and let moisture in the gaps between the glass panes. It is important to recognise when seals are beginning to leak and this means that the double glazing isn't performing as well as it once was. This could result in lower energy efficiency, increased heating bills, damage to the properties and the risk of condensation between the windows.
Mist
If you notice condensation on the outside of your windows, this is perfectly normal and means that your double-glazed is functioning properly and retaining the heat in your home. The condensation happens because the air outside is hotter than the glass, and reaches the dew point of the window prior to the air inside. This is one of the great advantages of having high-quality double glazing.
If the condensation is on the inside of your window then this can be a sign of a problem with the ventilation in your home.

This can be prevented by having it examined by an expert and ensuring that there is enough fresh air inside your home.

Most repairs can be made without the need to replace the entire window.
