Double Glazed Windows Repairs
It could be that your double-glazed windows aren't easy to open or have fog between the panes. If this is the case, it will be worth arranging for them to be repaired.
This can be done without replacing the windows and will be much less expensive in the long term. However, very specific tools are required and it is best to let a professional handle this kind of repair.
Damaged Seals
The window seals wear down over time, allowing argon gas or Krypton to escape through the panes of double- or triple-paned windows. If you've got a damaged seal, air from outside is getting in and the argon which helps to insulate your home is being emitted, both of which are detrimental to energy efficiency.
The reason window seals can break is that they are exposed to extremes of temperature and humidity, as well as pressure. repair double glazing windows can make your window glass expand and contract. This puts pressure on the seals. This is especially true when you have pets or children who can accidentally hit your windows.
If your window seal is damaged, it's a good idea to have the issue investigated by a professional as quickly as you can. If you delay too long then the argon gas, or krypton gas could escape completely and decrease the insulation properties of your windows.
Fog between the window panes is another common sign of a failing seal. While it's possible to fix this yourself by defogging, the best way is to get a specialist to come out and reseal your window.
A technician will remove the seal on the window and clean the glass. Then, install the new seal once windows are sealed. This will require disassembling the sash if necessary and then reassembling it, and replacing the IGU (insulated glass unit) in the event that it is required. Then, they will insert argon (or krypton) into the void in between the panes. They will also re-seal the IGU to ensure an airtight seal. There are kits available that claim to aid homeowners with this process. Reviews of these kits are mixed however, and we would recommend leaving this work to the professionals.
Condensation
Condensation is a concern when double glazing is used. This is particularly true in older homes. It happens when the air inside a home has a higher dewpoint and is warmer than the glass, leading to condensation to occur. It is more likely to occur during late at night or in the early morning hours, when temperatures are lowest.

If this spacer bar is filled with moisture, it may start to leak into frame of the window, which is where condensation forms.
It is also important to remember that the majority of new double-glazed windows are still under warranty and should be reported to the company who installed the windows.
