Broken Panes

When a window pane is broken, it loses its insulating properties and can create a draft. If the muntins that separate the glass panes are also broken, water can get in between them and cause condensation or mildew, or mould. This can make your home less energy efficient. A broken window is best repaired by an expert to ensure that you get the correct seal and optimum energy efficiency.

The first step is to take out any broken glass. Start by placing a low-cost glass cutter in a hardware store under the broken pane. It's a good idea to grease the cutter with light oil prior to when you begin. This will stop the glass from breaking too easily. You can then use the tool's ball-shaped end to break up the glass fragments and the glass should break away quickly.

Once the glass is removed, scrape off any old glazing compound from the recess of the frame. This will expose the metal clips and glazier's pins that keep the glass in place. Replace them if there is any corrosion. If the window is constructed of wood the glazier points may be reused if still in good condition.

The surface of the remaining frame must be prepared for reflazing. Apply a continuous strip of compound to the recess with the caulking tool. Use a high-quality putty such as glazier's compounds that is available in a cartridge or conventional compound sold in a can. Let it dry before installing the glass. Reinstall the metal clips, if they are on the frame. Reinstall the divider muntins.

Condensation

Condensation is a concern for double-glazed windows, especially during winter. It's usually caused by excessive humidity in the home, with warm air meeting cold glass, which turns into water droplets, and then collects in the corners of your windows or across the frame. You can prevent this from happening by opening your windows more frequently, improving ventilation with extractor fans, and running dehumidifiers. If condensation continues to occur it is recommended to contact an expert who can identify the problem and repair or replace the windows if required.

Condensation on a double-glazed glass window is a sign the seal has failed. The vacuum seal applied at the factory could wear away over time and allow cool air to pass between the panes. This can lead to fogging of the window and eventually, mold growth if not addressed promptly enough.

You can use a hairdryer for a quick way to get rid of excess moisture. This is a temporary fix and should only be used as a final option. If the condensation has been allowed to sit for too long, you may be experiencing mould or dampness in your home, which should be addressed by a professional.

They'll remove the affected pane of glass, clear the gap and pipe into hot air to eliminate any remaining moisture. During this process, they'll also examine for any the presence of mildew, mold or damage growth, and then apply a draught-proofing treatment to ensure that your windows are fully functional and energy efficient once again.

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 typically a simple problem that can be fixed by re-installing the gaskets and this will result in a sturdy and airtight seal. This will keep the warm air inside your home and the colder air outside, saving you cash on your energy bills.

Double glazing that has mist could be an indication of sealed blown seals. The unit consists of 2 panes of glass separated by a spacer bar to create an insulating gap. Then, it is filled with gas, such as argon for example, to make the window airtight. If the seal has been blown it will allow water vapour to get into your space through the gap, creating condensation between the panes that can't be removed.

This is a simple issue to fix and windows can be easily replaced by experts using the right tools. The specialist will use an instrument designed to push into the new seals. This is generally faster than doing it by hand. These tools also come with a pointed end that can be helpful to push the seals into the corners.

Faulty Hinges

Misted double glazing is a typical problem that many people encounter. This can be caused by broken or cracked glass frame, or even a broken seal. The good news is that it can often be solved. Usually, this means making a new seal between the two glass panes. The new seal will stop condensation, draughts, and leaks from occurring.

Broken Seals

Double glazed windows are secured by seals on windows or gas. Many factors can cause them to break, including the weather, age, and power washing. It's essential to be aware of what signs are and how to repair them.

When a window seal fails it allows humidity to seep in between the two glass panes, causing fog. This is a common issue, and can cause the window to look visually altered. When the seal fails it is when any argon or other inert gas will be removed from the glass, thereby decreasing its insulation properties.

A professional glazier can replace a broken window seal with a brand new one. This is costly and may not completely solve the fog issue. Certain companies offer defogging, which involves placing a vacuum pump inside the window repairs frame in order to remove moisture and clear the glass. This method is not foolproof, and it doesn't replace inert gasses, meaning that fog could return.

If the IGU (insulated unit) is beyond repair, a glazier could replace it. This is typically the most cost-effective solution and could be a good option when you're seeking the long-term solution.
