Broken Panes

When a window is broken and shattered, it loses its insulation and can cause a draft. If the muntins that divide the glass panes are also damaged, moisture could leak between them causing condensation and mildew, as well as mould. This will make your home less efficient in energy use. It is best to have a professional repair the damaged window in order to get the most effective seal and energy efficiency.

First, you'll need to take the broken glass off. Start by placing a protective drop cloth underneath the broken window and then cutting around the edges of the pane using an inexpensive glass cutter (available in a majority of hardware stores). It's recommended to lubricate the cutter with light oil prior to when you begin. This will help prevent the glass from breaking too easily. Then, you can use the tool's ball-shaped end to loosen the fragments, which should come off fairly quickly.

Once the glass is removed, scrape any old glazing compound from the recess area of the frame. This will reveal the glazier's clips and pins that hold the glass in place. Replace them if there is any corrosion. If the window is made of wood the glazier's points could be reused if they're intact.

The remaining frame will need to be prepared for the re-glazing. Apply a continuous strip compound to the recess with a caulking tool. Use a high quality putty such as a glazier’s compound in a cartridge. Let it dry before reinstalling the glass. Reinstall the metal clips if they are on the frame. Then, you can put back the divider muntins.

Condensation

Condensation is a concern for double-glazed windows, particularly in winter. It is typically caused by too many levels of moisture in your home. Warm air collides with cold glass and condenses into droplets of water. These droplets then accumulate in the corners and frame of the window. You can prevent this from happening by opening your windows more frequently and enhancing ventilation by installing extractor fans, and utilizing dehumidifiers. If condensation continues to occur you should contact a professional who can diagnose the problem and repair or replace the windows if needed.

Condensation on a double-glazed window is a sign the seal has failed. This is because the factory applied vacuum seal can break down over time, allowing cool air to make its way between the panes. This could lead to fogging of the window and eventually, mold growth if not dealt with quickly enough.

As a quick fix to condensation, you could try using a hairdryer to dry up the excess moisture. This is a temporary fix and should be used only as a last alternative.

Draughts

As time passes, the rubber seals around the edges of your glass are likely to be damaged and create a draught in space between the two panes. This is often a simple problem that can be fixed by re-installing the gaskets and this will result in a solid and airtight seal. This will keep warm air inside your home and cooler air outside. You will save money on your energy bill.

Misted double glazing is a sign that the seals inside the sealed unit (sometimes called a DGU) have blown. The unit is comprised of two panes of glass filled with argon separated by a spacer to create an airtight window. If the seal has blown, water vapour will enter your home through the gap. This can result in condensation between the glass panes, which is not able to be removed.

This is a straightforward issue to solve, and windows can be quickly repaired by professionals using the right tools. The expert will employ a tool designed to push the new seals in place and it is usually faster than trying to do it manually.

Broken Seals

Window Replacement seals, also known as insulation gas fills, are what keep double glazed windows in place. Many factors can cause them to break, like age, weather conditions and power washing, therefore it's crucial to be aware of what the symptoms are and how to repair them.

When a window seal fails humid air can get between the two panes of glass, causing fog. This is a frequent issue that can also make the window appear disfigured. When the seal is damaged, gas like argon as well as other inert gases are removed from the window, thereby reducing the glass's insulating qualities.

A damaged window seal can be fixed by replacing it with a new one by a professional glazier. This can be expensive and might not be able to resolve the fog issue. Certain companies offer defogging, which involves placing a vacuum pump inside the window frame to eliminate moisture and clear the glass. However, this method is not 100% reliable and cannot replace any inert gases, meaning that the fog can be re-applied.

A glazier is also able to replace the entire IGU (insulated glass unit) if it is beyond repair. This is usually the most cost-effective solution and is a great option in the event you're looking for a long-term solution. But, it's best to choose a firm with a guarantee for replacement windows to ensure that any issues are protected. This way, you can rest at ease knowing that you'll get most out of your investment. Alternately, you can try to avoid this issue by choosing a premium window and following the manufacturer's care instructions. This will prolong the life of the window and cut down the number of repairs.
