It's worth lubricating this tool's cutter with a light oil before you begin. This will prevent the glass from breaking too easily. You can then make use of the tool's ball-shaped tip to loosen the fragments and they should fall away quickly.

Scrape any old glazing compound out of the recess of the frame after the glass is removed. This will reveal the glazier's clips and pins that hold the glass in the frame. Replace them if you notice any corrosion. If the window is made of wood the glazier points can be reused if they're still in good condition.

The remaining frame will need to be prepared to allow re-glazing. Using a caulking gun, apply a continuous ribbon of compound along the inside edge of the recess.

Condensation

Condensation is one of the most common issues that double-glazed windows may experience, especially in the winter months. This is usually caused by high moisture levels within your home. Warm air is absorbed by cold glass, which condenses into droplets of water. These then collect in the corners and frame of the window.

Draughts

As time passes by, the rubber seals around the edges of your glass insulated can break down and this can create a draught in the space between the two panes.

This can cause condensation between the glass panes which is not able to be removed.
