How to Repair Double Glazed Windows
There are some telltale signs your double-glazed windows need to be fixed. Water ingress or draughts leaking through the frames are an obvious indication of window damage and will need to be fixed as soon as is possible.
However, misting may be an indication that your window seals need replacing. Replacing the seals will solve the problem and prevent condensation, draughts or leaks.
Broken Panes
Broken glass is one of the most frequent problems that double-glazed windows confront. While double pane windows are much harder to break than single-pane ones however, accidents can occur and you'll need to repair a broken window as soon as you can.
The first step is to take out any loose shards of glass that remain in the frame. Be sure to wear eye protection and gloves when doing this, as glass can be extremely sharp. Examine the floor for fragments that have fallen off after the shards are gone. Also, it is recommended to search for any hooks of metal that may be holding the panes together and take them out as well.
Once the glass has been removed, you'll need to remove the old glazing compound (small fasteners that fix the glass in the window frame) and replace them with new ones. It's a lengthy procedure that requires the use of a few tools. You will require latex glazing putty and metal glazing points, pliers an electric heat gun, and a putty blade.
When removing the old glazing compound and points, it's recommended to begin at the top of the sash, and work your way down. This will keep any wood or paint that is removed that is left in the sash from sticking to the tool. If you're looking to take off some of the wood from the sash, make use of a utility knife or a chisel instead of chemical strippers, which could cause damage.

Condensation
If you've noticed moisture or mist between the glass panes of your double glazing, it's a sign that one of your windows is suffering from a failing seal.

To resolve the issue your window company will remove the affected window sash as well as the IGU (insulating glass unit) before blowing in a new gasket. This will create a sturdy and airtight seal that will stop condensation from happening again. They will also employ a drying agent to help the area dry out and prevent the condensation from occurring again.
