A broken window is best repaired by an expert to ensure you get the correct seal and optimum energy efficiency.

Then, you can use the tool's ball-shaped end to break up the glass fragments and they should fall off fairly quickly.

This will reveal the metal clips and glazier's pins that hold the glass in place. If there's any indication of corrosion, these clips should be replaced with new ones. If the window is constructed of wood the glazier points can be reused if they are still in good condition.

You'll need to prepare the surface of the frame for reglazing. Using a caulking gun, apply a continuous strip of compound around the inner edge of the recess. Use a high-quality putty, such as Glazier's compound in cartridge. Dry it out before installing the glass. Reinstall the metal clips, if they are on the frame. Reinstall the divider muntins.

Condensation can be a problem for double-glazed windows, especially during winter.

Draughts

As time goes by the rubber seals around the edges of your insulated glass can fall apart and cause a draught to form in the space between the two panes.

This can result in condensation between the glass panes, which cannot be removed.

If a window seal is damaged, it allows humid air to seep in between the two glass panes and create fog. It's a frequent issue and it can cause the window to appear visually altered. Once the seal fails, the inert gases argon and others are removed from the window, further diminishing the glass's insulation capabilities.

A broken window seal can be repaired by replacing it with a new one by an experienced glazier. However, this is costly and might not resolve the fog problem entirely. Certain companies offer defogging, which involves putting an air pump inside the frame of the window to remove moisture and clear the glass. This method isn't 100% reliable and does not replace inert gasses, meaning that fog may return.

A glazier can also replace the entire IGU (insulated glass unit) in the event that it is beyond repair.
