Double Glazed Windows Repairs

Double-glazed windows may require repair for a variety of reasons like condensation between the panes, draughts or frames that are sliding. Fortunately, the majority of problems can be addressed.

Try to lubricate the hinges, handles and mechanisms of your door or window when it is difficult to open. This is a quick and inexpensive solution.

Broken Panes

When a window pane is broken it loses its insulation properties and can cause a draft. If the dividing muntins are broken, it could cause moisture to leak between the glass panes, leading to condensation, mold and mildew and making your home less efficient in energy use. A damaged window should be repaired by an expert to ensure you get a proper seal and the optimum energy efficiency.

First, you will need to take out any broken glass. Start by placing a low-cost glass cutter in an hardware store underneath the broken pane. It's a good idea to grease the cutter with lightweight oil before you begin. This will help prevent the glass from breaking too easily. The ball-shaped end of the tool can be used to break the pieces. They should fall off relatively quickly.

Scrape any old glazing compound out of the frame's recess once the glass has been removed. This will reveal the glazier's clips and pins that keep the glass in the frame. Replace them if there's any corrosion. If the window is made of wood the glazier points may be reused if they're still in good shape.

You'll then need to prepare the surface of the frame to be re-glazed. Utilizing a caulking gun apply a continuous strip of compound around the inner edge of the recess. Use a high quality putty such as a Glazier's compound in a cartridge. Let it dry before inserting the glass. If the frame has metal clippings, these should be removed as well. Then, you can reinstall the divider muntins.

Condensation

Condensation is a frequent issue that double-glazed windows face, especially in the winter months. This is usually caused by excessive levels of moisture in your home. Warm air meets cold glass and condenses to droplets of water. These then collect in the corners and frame of the window. You can avoid this by opening your windows more frequently and improving ventilation with extractor fans, and using dehumidifiers. If condensation continues to occur it is recommended to contact a professional who can diagnose the issue and repair or replace the windows if required.

It's also important to know that condensation on a double-glazed window can be an indication of a leaky seal. This is because the vacuum seal that was applied by the manufacturer can become degraded 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 addressed quickly enough.

As a quick fix to condensation, you can try using hair dryers to eliminate the excess moisture. This is a temporary fix and should be used only as a final option. If the condensation is allowed to sit for too long you might be facing mould or dampness in your home, which should be dealt with by a professional.

As a longer-term solution, you can get your double-glazed windows sealed by experts. They will remove the affected glass pane and clean the gap. They will then pipe hot air into the area to dry out any moisture. During the process, they will also look for any damage or growth of mould, mildew or mildew and then perform a draught proofing treatment to ensure that your windows are fully efficient and energy efficient once more.

Draughts

As time passes by, the rubber seals around the edges of your insulated glass can break down and this can cause a draught to form in the space between the two panes. This is usually a minor issue that can be resolved 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 out. You'll save money on your energy bills.

Misted double glazing is a sign that the seals of your sealed unit (sometimes called a DGU) have been blown. The unit is composed of two panes of argon-filled glass separated by a spacer to create an airtight window. If the seal is blown it allows water vapour to enter your room through the gap, causing condensation between the panes that cannot be wiped off.

Fortunately, this is an easy problem to fix, and windows can be replaced very quickly by professionals who have all the right tools and know how to do it properly. The professional will employ an instrument that is designed to push into the new seals. This is generally faster than doing it by hand. These tools also have a pointed end which can be useful to push the seals into the corners.

In some cases, a professional might be able to "reseal' your windows by drilling a small opening into the window and then adding a special desiccant material or putty. This can be an economical alternative to replacements and will provide a reliable draught-proofing system for your double-glazed windows.

Broken Seals

Window seals, also known as insulation gas fills, keep double-glazed windows in place. They can be damaged by various elements, including age, weather conditions, and power washing. It is crucial to recognize the signs and how to fix them.


When a window seal fails, it allows humid air to get into the two glass panes and create fog. This is a frequent issue that can also make the window appear to be distorted. When the seal fails it is when any argon or other inert gas is lost from the glass, further diminishing its insulating properties.

A damaged window seal can be fixed by replacing it with a new one by a professional glazier. However, this is expensive and may not resolve the fog problem entirely. Certain companies offer defogging services that involve putting the vacuum pump of a specific type inside the window frame to eliminate the moisture and make the glass clean. This method isn't foolproof and does not replace the inert gasses, which means that the fog could be re-created.

A glazier is also able to replace the entire IGU (insulated glass unit) when it's beyond repair. This is usually the most cost-effective solution and can be a good choice in the event you're looking for an option that lasts for a long time. However, it's best to select a company that has a warranty on replacement windows to ensure that any issues are protected. You can be certain that your investment will produce the best results. Alternatively, you can attempt to avoid this issue by choosing a premium window and following the manufacturer's maintenance instructions. This will extend the life of the window and reduce the amount of repairs.
