Double Glazed Windows Repairs

There are a variety of reasons your double-glazed windows could require repairs, from condensation between panes, to dropping or sagging frames. Most of these problems are fixable.

Try to lubricate the hinges, handles and mechanisms of your door or window in case it is hard to open. This is a simple, cheap fix.

Broken Panes


If a window pane is damaged and shattered, it loses its insulation and can cause a draft. If the dividing muntins are broken it can cause water to escape between the glass panes resulting in condensation, mould and mildew and making your home less energy efficient. It is recommended to have a professional repair a broken window to ensure the most effective seal and energy efficiency.

In the beginning, you'll have to take the broken glass off. Start by placing a low-cost glass cutter in a hardware store under the broken pane. It's worth lubricating this tool's cutter with a light oil before you begin. This will prevent the glass from breaking too easily. Then, you can use the tool's ball-shaped end to loosen the fragments and they should fall away quickly.

After the glass has been removed, scrape any glazing compound that is old from the recess area of the frame. This will expose the glazier's clips and pins that hold the glass in the frame. 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 may be reused if they are still intact.

You'll then need to prepare the surface of the remaining frame for reglazing. Utilizing a caulking gun apply a continuous strip of compound around the inside edge of the recess. Use a high quality putty, such as glazier’s compound in a cartridge. It should dry before installing the glass. If the frame has metal clippings, they should be reinstalled too. Install the dividers.

Condensation

Condensation is a frequent issue that double-glazed windows can experience particularly in wintertime. It's typically caused by excessive moisture in the house, with warm air meeting cold glass, which condenses into water droplets and collects in the corners of your windows or across the frame. You can stop this from happening by opening your windows more often and enhancing ventilation by installing extractor fans, and utilizing dehumidifiers. If condensation is still an issue, it's best to call in a professional to get to the bottom of the issue and fix or replace your windows when necessary.

Condensation on a double-glazed window is a sign the seal has failed. This is due to the vacuum seal that was applied by the manufacturer may break down in time, allowing cool air to move between the panes. This can cause the window to fog up and eventually develop mold if it is not addressed quickly.

A hairdryer can be used as a quick solution to eliminate excess moisture. But, this is only an interim solution and should be only used as a last option. If you let the condensation sit for too long, it may cause dampness or mould in your home. This should be handled by an expert.

Professionals can reseal double-glazed windows for a better, more durable solution. They'll take off the affected pane of glass, clear the gap and pipe in hot air to evaporate any remaining moisture. During the process, they'll also look for any signs of damage, mildew or mould growth and apply an draught-proofing procedure to ensure that your windows are fully efficient and energy efficient once more.

Draughts

Rubber seals can wear out over time and cause drafts between the two panes. It is an easy fix to replace the gaskets which will create an airtight seal. This will keep warm air inside your home, and cooler air outside. You'll save money on your energy bill.

Double glazing that is misted may be a sign of sealed blown seals. The unit is composed of two glass panes filled with argon separated by a spacer to form an airtight window. If the seal has blown water vapour can enter your home through the gap. This will create condensation between the glass panes, which can't be sucked out.

This is a simple issue to solve, and windows can be quickly replaced by specialists with the appropriate tools. The professional will employ tools designed to push the new seals into position and this is normally quicker than trying to do it manually. These tools feature a pointed tip that can be used to push the seals into corners.

A professional could be able to seal your windows by drilling a small opening into the window and adding a desiccant or putty. This could be an economical alternative to replacements and will offer a reliable protection against draughts for your double-glazed windows.

Faulty Hinges

Misted double glazing is a typical problem that many people experience. It may be caused by a damaged seal or a crack in the glass, or an issue with the mechanism or frame. It is usually possible to fix this problem. Normally, this involves making an entirely new seal between the two panes of glass. The new seal will prevent leaks, condensation and draughts from occurring.

Contact the company from which you bought your windows and let them know of any issues when you notice them. You should notify the company in writing and demand confirmation that they have received your notice.

Broken Seals

Double-glazed windows are held in place by window seals or insulation gas. They are susceptible to damage due to many elements, including age, weather conditions, and power washing. It is crucial to recognize the signs and the best way to repair them.

When a window seal breaks it allows humidity to get into the two glass panes and create fog. This is a common issue, and it can also cause the window to look visually disoriented. When the seal is damaged, the inert gases argon and others are lost from the window, further diminishing the glass's insulation capabilities.

A professional glazier can replace a broken window seal with a new one. However, this could be costly and might not resolve the fog problem entirely. Certain companies offer defogging, which involves placing an air-pump inside the frame of the window to eliminate moisture and clear the glass. This method is not foolproof and does not replace inert gasses, so the fog could be re-created.

If the IGU (insulated unit) is beyond repair, a glazier could replace it. This is the most cost-effective solution and is a good option if you're seeking a long-term solution. It is recommended to choose an option that provides warranties on replacement windows. This will ensure that any issues you might face are covered. You can be assured that your investment will provide the most effective results. Alternatively, you can try to avoid this problem by choosing a high-quality window and following the manufacturer's care instructions. This will help to prolong the lifespan of your window and decrease the need for repairs.
