Double Glazed Windows Repairs
There are a variety of reasons your double glazed windows might require repairs including condensation between panes, to drop or sagged frames. Most of these problems can be resolved.
Try applying lubrication to the hinges, handles and mechanism of your door or window if it is difficult to open. This is a simple, inexpensive solution.
Broken Panes
If a window pane breaks, it loses its insulation properties and may cause draft. If the dividing muntins are broken it can cause water to leak through the glass panes, resulting in condensation, mold and mildew and making your home less energy efficient. It is best to have a professional repair a broken window in order to get the best seal and energy efficiency.
In the beginning, you'll have to remove the broken glass. Begin by placing a protective drop cloth underneath the broken window and then cutting around the perimeter of the pane with an inexpensive glass cutter (available in most hardware stores). It's recommended to lubricate the cutter with lightweight oil before you begin. This will stop the glass from breaking too easily. You can then make use of the tool's ball-shaped tip to loosen the pieces and the glass should break away fairly quickly.
Once the glass is removed, scrape any glazing compound that is old from the recess of the frame. This will expose the metal clips and glazier's pins that hold the glass in place. If there's evidence of corrosion, the clips must be replaced with new ones. If the window is constructed of wood the glazier points may be reused if still intact.
The remaining frame must be prepared to allow re-glazing. Apply a continuous strip compound to the recess using a caulking tool. Use a high quality putty, such as Glazier's compound in a cartridge. Allow it to dry prior to inserting the glass. If the frame has metal clippings, they must be reinstalled too. Then, you can put back the divider muntins.
Condensation
Condensation is a concern for double-glazed windows, particularly in winter. It is typically caused by excessive moisture levels within your home. Warm air collides with cold glass and condenses to water droplets. They then settle in the corners or frame of the window. You can prevent this from happening by opening your windows more frequently and enhancing ventilation by installing extractor fans, and running dehumidifiers. If condensation continues to occur it is recommended to contact an expert who can identify the issue and fix or replace the windows if required.
It's also important to know that condensation on a double-glazed window could be a sign of a leaky seal. The vacuum seal applied at the factory could wear away over time and let cool air get between the panes. This can cause the window to get smudged and eventually grow mold if it's not addressed promptly.
As a quick fix for condensation, you could try using hair dryers to eliminate the excess moisture. This is only a temporary solution and should be used only as a last resort. If you leave the condensation for too long, it may cause dampness or mould in your home. This issue should be handled by an expert.
As a long-term solution, you can get your double-glazed windows sealed by experts. They'll take off the affected pane of glass, clear the gap, and then pipe in hot air to evaporate any moisture that remains. During the process, they will also check for any damage or growth of mould, mildew or mildew and then perform a draught proofing treatment to ensure that your windows are functional and energy efficient.
Draughts

Rubber seals can wear out over time and cause drafts between the two panes. It's simple to replace the gaskets which will create an airtight seal. This will keep warm air inside your home and cooler air outside. You will save money on your energy bill.
Misted double glazing is a sign the seals of your sealed unit (sometimes called a DGU) have been blown. The unit is comprised of two panes of glass that are separated by the spacer bar to create an insulating gap. Then, it is filled with gas, for example argon, to make the window airtight. If the seal has been blown it allows water vapour to enter your room through the gap, which will cause condensation between the panes which cannot be wiped off.
Fortunately it is a simple problem to fix, and the windows can be replaced very quickly by experts who have the appropriate tools and know how to do it right. The specialist will use an instrument designed to push in the new seals. This is generally faster than doing it by hand. The tools have an edge that can be used to push the seals into corners.
In certain situations, a professional could be able to "reseal your windows' by drilling a small hole into the window and adding an adsorbent material or putty. This is a more cost-effective solution than replacements and will give you an effective draught-proofing system for your double-glazed windows.
Faulty Hinges
Misted double glazing is a frequent problem that many people experience. It could 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 creating a seal between two glass panes. The new seal will help prevent condensation, draughts, and leaks.

Having everything in written form will make it easier to resolve any disputes arise, since it is easier to prove that you actually complained.
A window repair professional could drill a hole between your windows to remove moisture and make the seal. However, this is generally only temporary and will not prevent the moisture from returning. It is also possible to replace the glass unit, which will ensure it is watertight.

Broken Seals
Double-glazed windows are held in place by seals for windows or insulation gas. Many factors can cause them to break, such as weather conditions, age and power washing, therefore it's crucial to be aware of what the symptoms are and how to repair them.
If a window seal is damaged, it allows humid air to get into the two glass panes, causing fog. It's a common problem, and it can also cause the window to appear visually disoriented. Once the seal fails, any argon or other inert gas is lost from the glass, thereby diminishing its insulating properties.
A damaged window seal can be fixed by replacing it with a an entirely new one by a professional glazier. This can be expensive and may not solve the fog issue. Certain companies offer defogging, which involves placing an air pump inside the window frame to eliminate moisture and make the glass clear. However this method isn't 100% reliable and cannot replace any inert gas, and the fog could be re-applied.
A glazier may also replace the entire IGU (insulated glass unit) if it is beyond repair. This is the most cost-effective option and can be a great choice if you are seeking a long-term solution. However, it's best to choose a firm with a guarantee for replacement windows to ensure that any problems are protected. This means you can be assured that you'll get the most out of your investment.
