Double Glazed Windows Repairs
If your double-glazed windows are hard to open or have a haze between the panes, this could be the result of faulty seals. It is worthwhile to get them repaired in the event of this happening.
This can be accomplished without replacing the windows and will be much less expensive in the long term. However, very specific tools are required, so it is normally best to let a professional handle this type of repair.
Damaged Seals
The window seals be worn down in time, allowing argon gas or Krypton to escape between the panes of double- or triple-paned windows. A broken seal allows air from outside to enter, and the argon gas used to insulate your home to escape. Both are bad for energy efficiency.
Window seals can be damaged by extremes in humidity, temperature and pressure. These changes cause your window glass to expand and shrink, which puts a lot of pressure on seals over time. This could happen if your pets or children accidentally bang on your windows.
If your window seal is damaged It's a good idea to have the issue investigated by a professional as fast as you can. If you put off the repair for too long and the argon gas or krypton could escape completely and lower your window's insulation properties.
Another common sign that the seal is failing is seeing fogging in between your window frames. It is possible to defog your windows, but it is best to call a professional out and seal the window.
When you have your windows resealed by a technician, they will remove the old seal, wash the panes and put in the new seal. This will require disassembling the sash if necessary, then re-assembling it and replacing the IGU (insulated glass unit) when needed. Then, they will insert argon or krypton into the space between the panes and seal around the IGU to ensure a watertight fit. You can buy kits that claim to aid homeowners in this process.

Condensation
Condensation is among the most common issues with double glazing, especially in older homes. repairing double glazing windows occurs when the air inside a house has a higher dewpoint and is warmer than the glass, which causes condensation to occur.

If the spacer bar is saturated with moisture, it can be leaking into the frame of the window where condensation can form.
It is 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.
