Broken Panes

If a window pane breaks, it loses its insulation properties and may cause a draft.

It is recommended to hire a professional repair the damaged window in order to get the best seal and energy efficiency.

Before starting, you should make sure to lubricate the cutter of this tool using a light oil. This will stop the glass from shattering too easily. The ball-shaped end of the tool can be used to loosen the pieces. They should be removed quite quickly.

Scrape any old glazing compound out of the recess of the frame once the glass is removed. This will reveal the glazier's facets and the metal clips that hold the pane in the frame. Replace them if there's any corrosion. If the window is made of wood the glazier's points could be re-used if they're still intact.

The surface of the remaining frame needs to be prepared for the re-glazing. Using a caulking gun, apply a continuous strip of compound along the inside edge of the recess. Use a high-quality putty such as glazier's compounds that comes in a cartridge or a conventional compound that comes in a tin. Let it dry before reinstalling the glass. Install the metal clips if they are attached to the frame. Install the dividers.

Condensation

Condensation is a frequent issue that double-glazed windows may experience, especially in the winter months. It's typically caused by excessive moisture in the home as warm air meets cold glass, which condenses into water droplets and then collects in the corners of your windows or across the frame. It can be prevented by opening windows more frequently and improving ventilation by installing extractor fans and running dehumidifiers in order to reduce the amount of moisture. If condensation is still an issue, it's crucial to contact an expert to determine the root of the issue. You can then fix or replace your windows if necessary.

Draughts

As time passes, the rubber seals around the edges of your glass are likely to be damaged and cause a draught to form in the space between the two panes.

A damaged window seal can be fixed by having it replaced with a new one by an experienced glazier. This can be costly and might not be able to resolve the fog issue. Some companies offer defogging services which include putting an air pump inside the window frame to eliminate the moisture and leave the glass clean. This method isn't 100% reliable and does not replace the inert gasses, meaning that fog could return.

A glazier may also replace the entire IGU (insulated glass unit) if it is beyond repair. This is typically the most cost-effective solution and is a great option in the event you're seeking an option that lasts for a long time. However, it's best to choose a company that offers a warranty for replacement windows to ensure that any issues are covered.

Alternatively, you can attempt to avoid this issue by choosing a high-quality window and following the manufacturer's care instructions. This will extend the life of your window and reduce the need for repairs.
