Double Glazed Windows Repairs
If your double-glazed windows are hard to open or have a mist between the panes this could be an indication of seals that are not working properly. If this is the case, it might be worth arranging for them to be repaired.
This is a far cheaper option than replacing the windows. This type repair requires specialized tools which is why it's advisable to leave this work to professionals.
Damaged Seals
The window seals get worn out in time, allowing argon gas or Krypton to escape between the panes of double or triple-paned windows. A broken seal allows outside air to enter and the argon gas that is used to insulate your home to escape. Both are detrimental to energy efficiency.
Window seals can be damaged by extremes in humidity, temperature and pressure. These changes cause the glass to expand and contract, which puts a lot of pressure on the seals over time. This is also a possibility if you have pets or children that accidentally smash into your windows.

This process isn't one you can do yourself, but you can find certain kits that claim to aid homeowners with this. These kits have received mixed reviews, but we recommend that you leave this task to professionals.
