Double Glazed Windows Repairs
There are a variety of reasons your double-glazed windows could need repairs such as condensation between panes to drop or sagged frames. Most of these problems are fixable.

Try to lubricate the hinges, handles and mechanism of your door or window if it is difficult to open. This is a quick, affordable fix.
Broken Panes
If a window pane is damaged, it loses its insulation and could cause draft. If the muntins that separate the glass panes also damaged, moisture could be leaking between them, causing condensation and mildew, as well as mould. This can make your home less efficient in energy use. It is recommended to hire a professional repair a broken window in order to get the most effective seal and energy efficiency.
In the beginning, you'll have to remove the broken glass. Begin by putting a drop cloth underneath the window that has been broken and cutting around the perimeter of the pane using an inexpensive glass cutter (available at most hardware stores). Before you start, make sure to lubricate the cutter of this tool using a light oil. This will prevent the glass from breaking too easily. You can then make use of the tool's ball-shaped tip to loosen the fragments, which should come away quickly.
Scrape any old glazing compound off the frame's recess once the glass is removed. This will expose the metal clips and glazier's pins that keep the glass in the frame. Replace them if you notice any corrosion. If the window is wooden the glazier's points could be reused if they're in good condition.
The remaining frame will need to be prepared to allow the re-glazing. Using a caulking gun, apply a continuous strip of compound around the inside edge of the recess. Make use of a high-quality glue such as a glazier's compound that is available in a cartridge or conventional compound that comes in a tin. Allow it to dry prior to re-inserting the glass. Reinstall the metal clips if they are attached to the frame. Reinstall the divider muntins.
Condensation
Condensation is one of the most common issues that double-glazed windows face particularly in winter months. It's typically caused by too much moisture in the home where warm air collides with cold glass. This then forms into water droplets and then collects in the corners of your windows or across the frame. It can be prevented by opening windows more regularly, improving ventilation through extractor fans, and using dehumidifiers in order to reduce the amount of moisture. If condensation is still an issue, it's crucial to call in a professional to get to the bottom of the issue and repair or replace your windows as needed.
It's also important to know that condensation on double-glazed windows can be an indication of a failing seal. The seals that are applied at the factory could wear away over time and allow cool air to get between the panes. This could lead to fogging of the window and eventually mold growth if not addressed promptly enough.
Hairdryers can be used to eliminate excess moisture. This is a temporary fix and should only be used as a last alternative. If you leave the condensation for too long, it may cause dampness or mould in your home. This issue should be handled by a professional.
As a longer-term solution, you can have your double-glazed windows repaired by experts. They'll take off the affected pane of glass, clean out the gaps and pipe into hot air to eliminate any remaining moisture. During this process, they'll also examine for any damage, mildew or mould growth and apply a draught-proofing process to ensure that your windows are completely operational and energy efficient again.
Draughts
As time passes, the rubber seals around the edges of your glass insulated can fall apart and create a draught in the space between the two panes. This is typically a simple issue that can be resolved by replacing the gaskets, and this will result in a sturdy and airtight seal once again. This will keep warm air in your home, and the colder air out, saving you cash on your energy bills.
Double glazing that is misted may be an indication of blown seals. The unit is made up of two panes of glass separated by the spacer bar to create an insulating space. It is then filled with gas, like argon, to make the window airtight. If the seal has blown it will allow water vapour to get into your space through the gap, which will cause condensation between the panes which cannot be wiped off.
This is a simple problem to repair, and windows can be quickly replaced by experts using the proper tools. The specialist will use an instrument designed to push into the new seals. This is typically faster than doing it manually. The tools also have a pointed end which can be useful to push the seals into the corners.
A professional could be able to seal your windows by drilling a small opening into the window and then adding a desiccant, or putty. This can be an economical alternative to replacements and it will still provide a reliable draught-proofing system for your double glazing.
Faulty Hinges
Misted double glazing is a common issue that many people face. window repairs could be caused by a damaged seal or crack in the glass or a problem with the frame or mechanism. The good news is that it can be easily fixed. Normally, this involves making a new seal between the two panes of glass. The new seal will help prevent condensation, draughts, and leaks.

If there is a dispute the fact that everything is written will make it easier to prove your complaint.

When a window seal fails, it allows humid air to enter between the two glass panes and create fog. It's a frequent issue and can cause the window to appear visually disoriented. When the seal fails, any argon or other inert gas will be removed from the glass, further decreasing its insulation properties.
A professional glazier can repair a damaged window seal with a new one. This can be expensive and might not be able to resolve the fog issue. Some companies offer defogging, which involves placing a vacuum pump inside the frame of the window to eliminate moisture and clear the glass. However this method isn't foolproof and doesn't replace any inert gases, meaning that the fog could return.
If the IGU (insulated unit) is beyond repair, a glazier could replace it. This is typically the most cost-effective option and is a great option in the event you're seeking the long-term solution. It is recommended to select a company that has a warranty on replacement windows to ensure that any issues are protected. You can be assured that your investment will yield the best results.

This will prolong the lifespan of the window and reduce the amount of repairs.
