Double Glazed Window Repair
Most double glazed windows come with a guarantee, and it's worth checking what this covers. It typically covers any issues with window hardware, such as hinges and locking mechanisms within the first 10 years.
A leak in the seal is usually the reason for mist appearing between your glass windows. This should be addressed immediately to prevent mold or damp growing within your home.
Condensation Between the Windows
If you notice condensation appearing between your windows, it is an indication that the sealing in the gases that insulate the window has failed. This can be a serious issue that needs to be dealt with as soon as you can especially in winter when humidity is at its highest. This could also cause damage to the sills, sealant and mould.
Double-glazed windows shouldn't be able to have condensation between the panes. This can be caused by excessive humidity or a particularly cold snap. The issue can usually be resolved without the need to replace an entire window. A professional can make small holes into the glass and spray the inside of the window with a specially-formulated cleaning solution. The water is then removed from the window and an anti-fogger device can be installed to stop any further buildup of moisture in the future.
Condensation can also happen between the windows as a result of air leakage, or other factors outside the window. In this case it can take a longer time for the moisture inside the window to accumulate, because the air must be sufficiently warm to evaporate the water molecules. In these situations it is best to replace double-glazed windows than trying to repair the sealed units.

A double-glazed window is constructed up of three or two pieces of insulated glass that are held together by a metal frame. The space between the windows is filled with an insulating gas like argon or Krypton and then sealed. The seal is responsible for preventing the gas used to insulate from escaping, and it also stops air and moisture from entering through the gap.
As windows age, seals may be damaged, allowing moisture to enter between the glass panes. It is important to recognise the signs of leaks in the seals, as it means that the double glazing is no longer performing as well as it used to. This can lead to lower energy efficiency, higher heating bills, property damage and the possibility of condensation forming between the windows.
Mist
It is normal to observe condensation on your windows. This indicates that your double glazing system is operating well and is able to keep heat in your house. The condensation forms because the air outside is warmer than the glass and it reaches its dew point before the window does. Double glazing of top quality is an excellent method to achieve this.
If you notice condensation on the inside of the window, it could be a sign of a ventilation issue within your home. This is because the excess moisture has no place to go and is deposited on your window or in carpets, furniture, and in other areas in your home. The process of having this examined by a professional and making sure that there is plenty of fresh air moving through the home will help avoid it from happening in the future.
Another reason why mist appears on double-glazed windows is because the seal between two glass panes has been broken. This can be caused by wear and tear or by using chemical cleaning products. The best option is to get the windows fixed as soon as you can.
