Double Glazed Windows Repairs
There are a variety of reasons your double-glazed windows may require repairs including condensation between panes, to drop or sagged frames. Fortunately, the majority of these issues can be resolved.
If your door or window is difficult to open try oiling the hinges, the mechanism and handles. This is a quick, inexpensive fix.
Broken Panes
When a window pane breaks it loses its insulating properties and could cause draft. If the dividing muntins are damaged, it could cause water to leak between the glass panes resulting in condensation, mold and mildew and making your home less energy efficient. It is recommended to have a professional repair the damaged window in order to get the best seal and energy efficiency.

First, you'll need to get rid of any broken glass. Begin by putting a drop cloth beneath the window that has been broken and cutting around the perimeter of the pane with an inexpensive glass cutter (available in most hardware stores). It's a good idea to grease the cutter with a light 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 relatively quickly.
Scrape any old glazing compound out of the recess of the frame once the glass is removed. This will reveal the glazier's facets and the metal clips that hold the pane in the frame. If there's any sign of corrosion, these clips should be replaced with new ones. If the window is wooden the glazier's points could be used again if they're in good condition.
The next step is to prepare the surface of the frame to be re-glazed. Apply a continuous strip of compound to the recess with a caulking tool. Make use of a high-quality glue such as glazier's compounds that is contained in a cartridge, or a standard compound that comes in a tin. Allow it to dry prior to re-inserting the glass. Reinstall the metal clips, if they are on the frame. Reinstall the divider muntins.
Condensation
Condensation is a common problem that double-glazed windows face particularly in wintertime. It's usually caused by too many moisture levels in your home. Warm air collides with cold glass and condenses into water droplets. These droplets then accumulate in the corners or frames of the window. This can be avoided by opening windows more frequently and enhancing ventilation with extractor fans and running dehumidifiers to lower the moisture levels. If condensation is still an issue, it's crucial to contact a professional to get to the root of the issue and repair or replace your windows if needed.
It's also important to note that condensation on a double-glazed window can actually be an indication of a failing seal. The seals that are applied at the factory can wear out over time and allow cool air to pass between the panes. This can cause fogging of the window, and eventually mold growth if it is not addressed promptly enough.
Hairdryers can be used to eliminate excess moisture. But, this is only temporary solution and should be only used as the last option. If you let the condensation sit for too long, it may lead to mould or dampness within your home. This issue should be dealt with by an expert.
As a long-term solution, you can have your double-glazed windows resealed by experts. They'll remove the affected pane of glass, then clean the gap and pipe in hot air to evaporate any lingering moisture. In the process, they'll check for damage, mould or mildew growth and apply an draught-proofing procedure to ensure that your windows are fully operational and energy efficient again.
Draughts
As time passes, the rubber seals around the edges of your glass insulated can be damaged and create a draught in the space between the two panes. This is often a simple problem that can be solved by replacing the gaskets, and this will result in a solid and airtight seal. This will allow warm air inside your home, and the colder air out, saving you money on your energy bills.
Double glazing that is misted could be a sign of sealed blown seals. The unit is made up of two glass panes filled with argon separated by a spacer, creating an airtight window. If the seal is blown it allows water vapour to enter your room through the gap, causing condensation between the panes which is not able to be cleaned off.
Fortunately, this is an easy problem to fix and the windows can be replaced very quickly by experts who have the appropriate tools and know how to do it properly. The expert will employ an instrument that is designed to push into the new seals. This is typically faster than doing it by hand. These tools have an angled tip that can be used to push the seals into corners.
A professional might be able to reseal your windows by drilling a small gap into the window and adding a desiccant or putty. This could be a more cost-effective solution than replacements and it will still offer a reliable draught-proofing solution for your double glazing.
Faulty Hinges
Many people have experienced misted double glazing. It can be caused by a damaged seal, or a crack in the glass, or an issue with the frame or mechanism. The good thing is that this can often be solved. This usually involves making a seal between the two glass panes. The new seal will help prevent condensation, draughts, as well as leaks.
If you discover any issues, you should contact the company that sold you your windows. Be sure to do this in writing, and ask them to confirm that they've received your notice. Making sure that everything is in writing will be helpful later if any disputes arise, since it is easier to prove that you did complain.
A window repair professional may drill the gap between your windows to remove moisture and make an airtight seal. This is only temporary and will not stop moisture from returning. In addition, it might be possible to replace the glass unit, which will ensure it is watertight.
It is important to keep in mind that you should only try DIY fixes only if you have the experience and know-how required to make the attempt. Utilizing super glue or any other kind of DIY solution could cause more damage in the long in the long run. It is always best to seek out professional assistance if you are unsure what to do.

Broken Seals
Window seals, or insulation gas fills, are what keep double glazed windows in place. There are a variety of reasons that can cause them to break, including weather conditions, age and power washing. It's important to know what the symptoms are and how to fix them.
If a window seal is damaged, it allows humid air to get into the two glass panes, creating fog. This is a common issue that can make the window appear disfigured. When the seal fails the argon or any other inert gas is removed from the glass, thereby diminishing its insulating properties.
A professional Glazier can replace a damaged window seal with a new one. This can be costly and may not solve the fog issue. Some companies offer defogging which involves placing an air-pump inside the frame of the window to remove moisture and clear the glass. However, this method is not foolproof and does not replace any inert gases, meaning that the fog may be re-applied.
A glazier is also able to replace the entire IGU (insulated glass unit) if it is beyond repair. This is the most cost-effective solution and is a great choice if you are looking for a long term solution. It is best to choose an option that provides warranties on replacement windows. This will ensure that any problems you may have are covered. You can be sure that your investment will yield the best results. You can also try to get rid of the issue by choosing the best quality product and following the maintenance instructions that are provided by the manufacturer. This will prolong the lifespan of the window and cut down the amount of repairs.
