Double Glazed Windows Repairs
Double-glazed windows require repair for a variety of reasons including condensation between the panes, draughts or sagging frames. Fortunately, the majority of these issues can be fixed.
Try to lubricate the hinges, handles, and mechanisms of your door or window in case it is hard to open. This is a quick and inexpensive solution.
Broken Panes
If a window pane breaks, it loses its insulation properties and may cause a draft. If the dividing muntins also broken, it could cause moisture to escape between the glass panes, leading to condensation, mould and mildew and making your home less energy efficient. It is best to have a professional repair a broken window to ensure the most effective seal and energy efficiency.
In the beginning, you'll have to take the broken glass off. Begin by putting a drop cloth beneath the broken window and then cutting around the perimeter of the pane using an inexpensive glass cutter (available in a majority of hardware stores). Before starting, you should grease the cutter with a light oil. This will stop the glass from shattering too easily. You can then make use of the tool's ball-shaped tip to break up the glass fragments and they should fall off fairly quickly.
Scrape any old glazing compound from the frame's recess after the glass has been removed. This will expose the glazier's clips and pins that hold the glass in place. Replace them if you notice any corrosion. If the window is constructed of wood, the glazier points can be reused if they are still in good condition.
The surface of the remaining frame will need to be prepared for re-glazing. 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. Let it dry before inserting the glass. Install the metal clips if they are attached to the frame. Reinstall the divider muntins.
Condensation
Condensation is a common problem that double-glazed windows may experience, especially in the winter months. It's usually caused by excessive moisture in the home where warm air collides with cold glass. This then turns into water droplets, and collects in the corners of your windows or across the frame. This can be prevented by opening windows more frequently and enhancing ventilation with extractor fans, and using dehumidifiers to lower the moisture levels. If condensation is still an issue, it's best to call in an expert to determine the root of the issue and fix or replace your windows if needed.
It's also important to know that condensation on a double-glazed window could be a sign of a failing seal. This is because the factory applied vacuum seal may be damaged in time and allow cool air to make its way between the panes. This can cause the window to get smudged and then develop mold if it is not addressed promptly.
As a quick fix to condensation, you can try using a hairdryer to dry up the excess moisture. This is a temporary fix and should only be used as a final resort. If you allow the condensation to sit for too long, it could cause dampness or mould in your home. This issue should be dealt with by an expert.
Professionals can seal your double-glazed window for a better, more durable solution. They'll remove the affected piece of glass, clean out the gap, and then pipe into hot air to evaporate any lingering moisture. During this process, they'll examine for any damage, mould or mildew growth, and then apply an draught-proofing procedure to ensure your windows are completely functional and energy efficient once again.
Draughts
The rubber seals get worn out over time and create drafts between your two panes. It is a simple fix to replace the gaskets which will result in an airtight seal. This will allow warm air in your home and the colder air outside, saving you cash on your energy bills.
Double glazing that has mist could be a sign of blown seals. The unit consists of 2 panes of glass separated by an insulating bar that creates an insulating space. It is then filled with gas, like argon, to make the window airtight. 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 can't be sucked out.
Fortunately, this is an easy problem to fix and windows can be replaced quickly by professionals who have the appropriate tools and know how to do it correctly. The expert will employ an instrument designed to push in the new seals. This is generally faster than doing it manually. These tools also have a pointed end which is useful for pushing seals into the 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 is less expensive than replacing your double glazing and still provides you with a Draught-proofing system.
Faulty Hinges
Many people have encountered misted double-glazing. It can be caused by cracked or broken glass or frame or even a damaged seal. It is often possible to resolve this issue. It is usually a matter of creating a seal between the two glass panes. The new seal will stop condensation, draughts, as well as leaks.
If you spot any problems, you should contact the company that sold you the windows. You should notify the company in writing and demand confirmation that they received your notification. If there are any disagreements, having everything in writing will make it easier to prove your case.
A window repair expert might be able to drill a hole in the gap between your windows to remove moisture and make an airtight seal. However, this is typically only a temporary solution and will not stop the return of moisture. It might also be possible to replace the glass, which would make it watertight.
Make sure that you only try DIY fixes if your skills and knowledge are sufficient. Super glue or other DIY solutions could cause more damage over the long term.

Broken Seals
Double-glazed windows are secured by seals for windows or insulation gas. They are susceptible to damage due to many elements, including age, weather conditions, and power washing. It is crucial to recognize the signs and how to fix them.
When a window seal fails, it allows humid air to get into the two glass panes, causing fog. It's a frequent issue and it can cause the window to look visually distorted. If the seal fails, the inert gases argon and others are lost from the window, further reducing the glass's insulating qualities.
A professional glazier can replace a broken window seal with a brand new one. This can be costly and might not be able to resolve the fog issue. Some companies offer defogging services that involve putting the vacuum pump of a specific type inside the window frame to eliminate the moisture and leave the glass clear. However this method isn't 100% reliable and cannot replace any inert gases, so the fog could return.
If the IGU (insulated unit) is beyond repair, a glazier may replace it. This is the most cost-effective method and can be a great choice if you are looking for a long term solution. It is recommended to choose an option that provides warranties on replacement windows. This will ensure that any issues you may have are covered. This means you can be assured that you'll get the most value from your investment. Alternately, you can try to avoid this issue by choosing a premium window and following the manufacturer's care instructions. This will help to prolong the life of your window and reduce the need for repairs.
