Double Glazed Windows Repairs

There are many reasons your double-glazed windows could need repairs, from condensation between panes to draughts and dropped or sagged frames. Fortunately, a majority of these issues can be fixed.

Try applying lubrication to the hinges, handles and mechanism of your door or window when it is difficult to open. This is usually a simple solution that is quick and easy to fix.

Broken Panes

If a window pane breaks, it loses its insulating properties and can create a draft. If the muntins that divide the glass panes are damaged, moisture could be leaking between them, causing condensation, mould or mildew. This will make your home less energy-efficient. A window that is damaged should be repaired by an expert to ensure that you get a perfect seal and maximum energy efficiency.

First, you'll need to remove any broken glass. Begin by placing a cheap glass cutter from an appliance store beneath the broken pane. Before starting, you should grease the cutter of this tool with a light oil. This will help prevent the glass from breaking too easily. Then, you can make use of the tool's ball-shaped tip to break up the glass fragments, which should come away fairly quickly.

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

The remaining frame needs to be prepared for 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 that is contained in a cartridge. Dry it out before reinstalling the glass. If the frame is made of metal clippings, they should be reinstalled too. Finally, put back the divider muntins.

Condensation

Condensation is a concern for double-glazed windows, especially during the winter. It is typically caused by excessive moisture levels in your home. Warm air is absorbed by cold glass and condenses into droplets of water. These then collect in the corners and frame of the window. You can prevent this from happening by opening your windows more often, improving ventilation with extractor fans, and using dehumidifiers. If condensation persists, you should call an expert who can identify the issue and repair or replace the windows if required.

Condensation on a double-glazed window is a sign that the seal has failed. This is because the vacuum seal that was applied by the manufacturer will become degraded in time, allowing cool air to make its way between the panes. This could lead to fogging of the window and eventually, mold growth if it is not addressed promptly enough.

A hairdryer can be used for a quick way to eliminate excess moisture. This is only a temporary solution and should be used only as a final alternative. If you allow the condensation to sit for too long, it could cause dampness or mould in your home. This should be dealt with by a professional.

Professionals can reseal your double-glazed window for a more permanent solution. They will remove the affected glass pane, clean the gap and pipe hot air into the area to eliminate any moisture. In this process, they'll check for damage, mould or mildew growth and carry out an draught-proofing procedure to ensure your windows are completely efficient and energy efficient again.

Draughts

Rubber seals may get worn out over time and cause drafts between your two panes. This is typically a simple issue that can be resolved by replacing the gaskets, and this will result in a sturdy and local airtight seal. This will allow warm air in your home and the colder air out, thereby saving you money on your energy bills.

Double glazing that is misted could be a sign of blown seals. The unit is comprised of two panes of glass filled with argon separated by a spacer, creating an airtight window. If the seal is blown the water vapour will get into your space through the gap. This will create condensation between the glass panes which is not able to be removed.

This is a straightforward issue to repair, and windows can be swiftly replaced by experts using the right tools. The specialist will use an instrument designed to push in the new seals. This is generally faster than doing it by hand. The tools also come with a pointed end which can be useful for pushing the seals into the corners.

A professional might be able to reseal your windows' by drilling a small opening into the window and then adding a desiccant, or putty. This is less expensive than replacing your double-glazed windows and still provides you with a reliable draught proofing system.

Faulty Hinges

Misted double glazing is a typical problem that many people encounter. It can be caused by cracked or broken glass or frame or even a broken seal. It is possible to fix this problem. It is usually a matter of making a seal between the two glass panes. The new seal will help prevent condensation, draughts, as well as leaks.

Contact the company from whom you purchased your windows, and local inform them of any problems immediately you discover them. Make sure to put this in writing, and ask them to confirm that they've received your notice. If there are any disputes, having everything in writing will help you prove your complaint.

In some instances the window repair expert may be able to drill a hole in your windows to draw moisture out and create a new seal. This is a temporary fix and will not stop moisture from resurfacing. It is also possible to replace the glass unit itself which will ensure it is watertight.

It is important to remember that you should only try DIY fixes when you have the skills and experience required to do so. Super glue or other DIY solutions can result in more damage over the long term. It is always best to seek out professional assistance when you aren't sure what to do.

Broken Seals

Double-glazed windows are secured by seals for windows or insulation gas. Many factors can cause them to break, including the weather, age, and power washing, therefore it's essential to be aware of what symptoms are and how to repair them.

If a window seal fails humid air can get between the two panes of glass, causing fog. This is a frequent issue that can cause the window appear to be distorted. Once the seal fails, any argon or other inert gas will be removed from the glass, further reducing its insulating properties.

A damaged window seal can be fixed by having it replaced with an entirely new one by an experienced glazier. However, this is expensive and may not solve the fog problem entirely. Certain companies offer defogging, which involves placing a vacuum pump inside the window frame to remove moisture and make the glass clear. This method isn't foolproof, and it does not replace the inert gasses, so the fog could return.

A glazier may also replace the entire IGU (insulated glass unit) when it's beyond repair. This is typically the most cost-effective solution and could be a good option when you're looking for an option that lasts for a long time. But, it's best to select a company with a guarantee for replacement windows to ensure that any problems are protected. You can be sure that your investment will provide the most effective results. Alternatively, you can try to avoid this issue by selecting a window of high-quality and following the manufacturer's care instructions. This will extend the life of your window and reduce the need for repairs.
