Double Glazed Windows Repairs
Double-glazed windows require repair for a variety of reasons, like condensation between the panes, draughts, or sagging frames. Fortunately, the majority of these issues can be fixed.
If your door or window is difficult to open, try oiling the mechanism, hinges and handles. This is a simple, cheap fix.
Broken Panes
When a window is broken it loses its insulation and can cause a draft. If the dividing muntins are also broken, it could cause moisture to leak between the glass panes, resulting in condensation, mold and mildew and making your home less energy efficient. A broken window is best repaired by an expert to ensure you get the correct seal and maximum energy efficiency.
In the beginning, you'll have to take the broken glass off. Start by placing a protective drop cloth underneath the broken window, and then scoring around the perimeter of the pane with an inexpensive glass cutter (available at most hardware stores). It's recommended to lubricate the cutter with lightweight oil before you begin. This will prevent the glass from breaking too easily. The ball-shaped tip of the tool can be used to loosen the pieces. They should fall off fairly quickly.
Once the glass is removed, scrape off any glazing compound that is old from the recess of the frame. This will expose the glazier's point and the metal clips that hold the pane in the frame. If there's evidence 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're still in good shape.
The surface of the remaining frame needs to be prepared to allow re-glazing. Apply a continuous strip compound to the recess with a caulking tool. Make use of a premium putty such as a Glazier's compound that is contained in cartridge. Allow it to dry prior to installing the glass. Install the metal clips if they are attached to the frame. Then, you can install the dividers.
Condensation
Condensation is a frequent issue that double-glazed windows face, especially in the wintertime. It is typically caused by too many moisture levels within your home. Warm air is absorbed by cold glass and condenses to water droplets. These droplets then accumulate in the corners and frame of the window. You can prevent this from happening by opening your windows more often and improving ventilation with extractor fans, and using dehumidifiers. If condensation remains an issue, it's best to contact an expert to get to the bottom of the issue and fix or replace your windows when required.
Condensation on a double-glazed glass window is a sign the seal has failed. The seals that are applied at the factory may wear away over time and let cool air get between the panes. This can cause the window to fog up and eventually develop mold if it is not addressed promptly.
You can use a hairdryer to get rid of excess moisture. This is a temporary fix and should be used only as a final resort. If the condensation is left for a long time it may be experiencing mold or dampness within your home, which must be dealt with by a professional.
Professionals can seal your double-glazed window for a better, more durable solution. They'll remove the damaged glass pane, clean the gap and pipe hot air into the gap to dry out any moisture. During the process, they'll examine for any damage, mould or mildew growth, and then apply an draught-proofing procedure to ensure that your windows are completely operational and energy efficient again.
Draughts
As time passes by, the rubber seals around the edges of your glass are likely to fall apart and create a draught in space between the two panes. This is typically a simple issue that can be resolved by replacing the gaskets, and this will create a strong and airtight seal. This will keep warm air inside your home and cooler air outside. You can reduce your energy bill.
Double glazing that is misted could be an indication of sealed blown seals. The unit is composed of two panes of argon-filled glass separated by a spacer to form an airtight window. If the seal has blown the water vapour will get into your home through the gap. This can cause condensation between the glass panes, which is not able to be removed.
This is a simple issue to solve and windows can be easily replaced by experts using the appropriate tools. The expert will employ an instrument designed to push in the new seals. This is usually quicker than doing it manually. These tools have 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 in the window, and then adding a desiccant or putty. This can be more cost-effective than replacements, and will provide a reliable draught-proofing solution for your double-glazed windows.
Faulty Hinges
Many people have encountered misted double-glazing. This can be caused by a cracked or broken glass or frame or even a broken seal. The good news is that this can be easily repaired. Usually, this means making a new seal between two glass panes. The new seal will stop condensation, draughts and leaks from happening.
If you discover any issues, you must contact the company that sold you your windows. Make sure you do this in writing and request them to confirm that they've received your message. If there are any disagreements the fact that everything is written will help you prove your case.
A window repair expert may drill the gap between your windows to remove moisture and make a seal. However, this is usually only a temporary fix and will not stop the moisture from returning. It might also be possible to replace just the glass part, which will make it watertight.
Make sure that you only attempt DIY fixes if your skills and knowledge are sufficient. Super glue or other DIY solutions can cause more long-term damage.

Broken Seals
Double glazed windows are held in place by window seals or insulation gas. A variety of factors can cause them to break, such as age, weather conditions and power washing, so it's crucial to be aware of what the signs are and how to repair them.
If a window seal is damaged it allows moisture to seep in between the two glass panes and create fog. It's a common problem, and it can also cause the window to look visually disoriented. If window repairs is damaged, any argon or other inert gas is removed from the glass, further diminishing its insulating properties.
A damaged window seal can be fixed by replacing it with an entirely new one by a professional glazier. However, this is expensive and may not resolve the fog problem entirely. Certain companies offer defogging, which involves putting an air pump inside the frame of the window to eliminate moisture and make the glass clear. This method is not foolproof, and it does not replace the inert gasses, so the fog can return.
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 option, and can be a good choice when you're seeking an option that lasts for a long time. It's best to select an option that provides warranties on replacement windows. This will ensure that any problems that you might encounter are covered. You can be assured that your investment will produce the most effective results. You can also avoid the problem by selecting the best quality product and following the care instructions that are provided by the manufacturer. This will extend the life of your window and minimize the need for repairs.
