Double Glazed Window Repair
Most double glazed windows come with a warranty, and it's worth examining the scope of this warranty. It typically covers any issues with window hardware, like hinges and locking mechanisms within the first ten years.
Mist in between glass windows can be caused by a breach in the seal and needs to be repaired quickly to prevent damp or mould developing in your property.
Condensation Between the Windows
If you notice condensation appearing between your windows, this could be an indication that the seal in the gas insulating the windows has failed. This can be a serious issue that should be addressed as soon as possible particularly in winter, when humidity is at its highest. This can also cause damage to sills, sealant and mould.

Double-glazed windows should not have condensation between the panes. However, it's not uncommon for high humidity or an extremely cold snap to trigger this problem. This issue is usually resolved without the need to replace the entire window. A professional can drill tiny holes into the window and spray special cleaning solution inside. The water is then removed from the window and an anti-fogger system can be added to prevent further accumulation of moisture in the future.
Condensation may also occur between windows due to air leakage, or any other cause outside the window. In this instance it could take longer for moisture in the window to build up as the air must be sufficiently warm to evaporate the water molecules. In these situations it is best to replace double-glazed windows than to try to repair the sealed units.
A double-glazed glass window comprised of two or more pieces of insulated tempered glass that are held together by a framework made of metal. The gap between the two windows is filled with an insulating gas like argon or Krypton and then sealed. The seal prevents the insulating gas from escaping, and it also stops air and moisture from getting into the gap.
As windows age, seals may deteriorate allowing moisture to leak between the glass panes. When the seals leak it is crucial to recognize this as it means that the double glazing isn't performing as efficiently as it did before. This could result in lower efficiency in energy use, higher heating bills, property damage, and the risk of condensation developing between the windows.
Mist
If you see condensation on the outside of your windows, it is totally normal - it means that your double glazing is functioning properly and retaining the heat in your home. The condensation develops because the outside air is more warm than the glass and it reaches its dew point before the window does. Double glazing of top quality is a fantastic way to get this.
If window security is located on the inside of your window, this can be a sign of a ventilation issue in your home.

Another reason for mist on double-glazed windows is because the seal between two glass panes is broken. This could be due to wear and tear or chemical cleaning products being employed. The most effective solution is to get the windows fixed as soon as you can.

It's not uncommon to find UPVC window handles and lock mechanisms to become stuck or unusable particularly when they're worn and old. This is due to an accumulation of grease or dirt inside the handle and can often be cured by cleaning it with a uPVC cleaner. If this doesn't work then you could try gently tapping the uPVC frame using a hard object like a screwdriver, being careful not to harm the handle or the window handle mechanism.
If this does not resolve the issue, then the window may need to be replaced as it is likely that the hinges aren't more in the proper position, or the locking mechanisms are damaged. In this case you should consult a UPVC window expert.

Warping
Double-glazed windows are usually a great option for saving energy in your home. They are made up of two distinct panes, with a spacer gas or air between the panes, which creates an airtight seal that keeps cold air out and warm air in. However, over time, these windows can be damaged or destroyed and require repair. Luckily, most of these repairs are simple and can be accomplished without the expense of replacing the entire window.
