Double glazed windows can need repair for a variety of reasons, like condensation between the panes, draughts or sagging frames. Thankfully, most of problems can be addressed.
Try applying lubrication to the hinges, handles and mechanism of your door or window if it is difficult to open. This is usually a simple, short-term fix.
Broken Panes
If a window pane breaks, it loses its insulating properties and may cause draft. If the dividing muntins are damaged, it could cause water to escape between the glass panes resulting in condensation, mould and mildew and making your home less efficient in energy use. It is recommended to have a professional repair a broken window to ensure the best seal and energy efficiency.
First, you will need to take out any broken glass. Begin by placing a cheap glass cutter from an appliance store beneath the broken pane. It's worth lubricating this tool's cutter with lightweight oil before you begin. This will stop the glass from breaking too easily. The ball-shaped tool can be used to loosen the pieces. They should be removed fairly quickly.
After the glass has been removed, scrape any old glazing compound that has accumulated in the recess of the frame. This will expose the glazier's clips and pins that hold the glass in the frame. If there's evidence of corrosion, the clips must be replaced with new ones. If the window is wooden, the glazier's points can be used again if they're in good condition.
You'll need to prepare the surface of the remaining frame to be re-glazed. Apply a continuous strip compound to the recess using the caulking tool. Use a high-quality putty such as a glazier's compound that is contained in a cartridge or conventional compound that comes in a tin. Dry it out before installing the glass. Install the metal clips if they are on the frame. Reinstall the divider muntins.
Condensation
Condensation is a frequent issue that double-glazed windows may experience, especially in the wintertime. It's typically caused by too much moisture in the house where warm air collides with cold glass. This then condenses into water droplets and then collects in the corners of your windows or across the frame. You can avoid this by opening your windows more frequently and improving ventilation with extractor fans, and running dehumidifiers. If condensation is still present you should contact a professional who can diagnose the issue and repair or replace the windows if required.
Condensation on a double-glazed glass window is a sign the seal has failed. The seals that are applied at the factory could wear away over time and let cool air get between the panes. This can lead to fogging of the window, and eventually mold growth if it is not addressed promptly enough.
A hairdryer can be used as a quick solution to get rid of excess moisture. However, this is just an interim solution and should only be used as an option last resort. If the condensation is left for a long time you may be experiencing mold or dampness in your home, which should be dealt with by a professional.
Professionals can seal your double-glazed window to provide a longer-lasting solution. They'll remove the damaged glass pane and clean the gap. They will then pipe hot air into the space to eliminate any moisture. During this process, they'll look for signs of damage, mould or mildew growth and apply a draught-proofing process to ensure your windows are fully functional and energy efficient once again.
Draughts
Rubber seals can get worn out over time and cause drafts between the two panes. This is often 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 out. You can reduce your energy bill.
Double glazing that is misted may be an indication of sealed blown seals. The unit is comprised of two panes of argon-filled glass separated by a spacer, creating an airtight window. If the seal has been blown water vapour can enter your space through the gap. This can cause condensation between the glass panes that can't be sucked out.
Fortunately, this is an easy issue to fix and the windows can be replaced very quickly by experts with the right tools and know how to do it right. The professional will employ a tool designed to push the new seals in place and is generally faster than attempting to do it by hand. The tools have an angled tip that can be used to push seals into corners.
A professional might be able to reseal your windows' by drilling a small gap in the window, and then adding a desiccant, or putty. This can be an economical alternative to replacements and will provide a reliable protection against draughts for your double-glazed windows.
Faulty Hinges
Misted double glazing is a common issue that many people face. It may be caused by a damaged seal or crack in the glass or an issue with the mechanism or frame. It is possible to fix this problem. Usually, this means making a new seal between two glass panes. The new seal will stop condensation, draughts and leaks from occurring.
Contact the company through which you bought your windows and tell them of any issues when you spot them. You should inform the company in writing and request confirmation that they received your message. Having everything in written form will help later on should any disputes arise, since it is easier to prove that you actually complained.
In some cases an expert in window repair will cut the hole in your windows to draw out moisture and create the new seal. However, this is usually only a temporary solution and will not stop the return of moisture. Alternatively, it may be possible to replace the glass unit itself which will ensure that it is watertight.
Make sure that you only attempt DIY fixes only if your skills and experience are adequate. Super glue or other DIY solutions could cause more damage over the long term.

Broken Seals
Window seals, also known as gas fills, are what keep double-glazed windows in place. Many factors can cause them to break, like weather conditions, age and power washing. It's important to know what the symptoms are and how to fix them.
When a window seal fails humid air can leak between the two panes of glass, causing fog. This is a common issue, and it can cause the window to appear visually distorted. When the seal fails it is when any argon or other inert gas is removed from the glass, further diminishing its insulating properties.
A broken window seal can be fixed by having it replaced with a new one by an experienced glazier. This can be expensive and might not be able to resolve the fog issue. Certain companies offer defogging, which involves putting a vacuum pump inside the window frame to eliminate moisture and make the glass clear. However, this method is not foolproof and doesn't replace any inert gases, meaning that the fog can come back.
If the IGU (insulated unit) is beyond repair, a glazier may replace it. This is usually the most cost-effective solution and could be a good option in the event you're looking for the long-term solution. However, it's best to select a company that has a warranty on replacement windows to ensure that any issues are protected. This means you can be assured that you'll get the most value from your investment. You can also avoid this issue by choosing an item of high-quality and following the care guidelines that are provided by the manufacturer. This will extend the lifespan of your window and minimize the need for repairs.
