Double Glazed Windows Repairs
Double-glazed windows require repair for many reasons, like condensation between the panes, draughts, or frames that are sagging. Fortunately, the majority of these issues can be resolved.

Try to lubricate the hinges, handles, and mechanisms of your window or door when it is difficult to open. This is a quick and cheap solution.
Broken Panes
If a window pane breaks, it loses its insulating properties and could cause draft.

A damaged window should be repaired by an expert to ensure you get the correct seal and optimum energy efficiency.
Firstly, you'll need to take the broken glass off. Start by placing an inexpensive glass cutter in an appliance store beneath the broken pane. Before you begin, make sure to lubricate the cutter with an oil that is light. This will stop the glass from shattering too easily. You can then use the tool's ball-shaped end to loosen the fragments and they should fall away quickly.
After the glass has been removed, scrape away any old glazing compound that has accumulated in the recess of the frame. This will expose the glazier's clips and pins that keep the glass in the frame. If there's evidence of corrosion, these should be replaced with new ones. If the window is made of wood, the glazier points can be reused if they're still in good condition.
The surface of the remaining frame will need to be prepared for reflazing. Using a caulking gun, apply a continuous ribbon of compound around the inner edge of the recess. Make use of a premium putty, such as Glazier's compound that is contained in a cartridge. Allow it to dry before installing the glass. If the frame has metal clippings, they must be replaced as well.
