Double Glazed Windows Repairs
There are many reasons your double glazed windows might require repair including condensation between panes, to dropping or sagging frames. Fortunately, a majority of these issues 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, affordable solution.
Broken Panes
When a window pane is broken, it loses its insulation and could cause draft. If the dividing muntins are also damaged, it could cause moisture 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 hire an expert repair a damaged window to ensure the best seal and energy efficiency.
First, you will need to get rid of any broken glass. Begin by placing a protective drop cloth under the broken window, and then scoring around the perimeter of the pane using an inexpensive glass cutter (available at most hardware stores). It's worth lubricating this tool's cutter with a light oil before you begin. This will help prevent the glass from breaking too easily. The ball-shaped tool can be used to break the fragments. They should be removed fairly quickly.
Scrape any old glazing compound from the frame's recess once the glass has been removed. This will reveal the glazier's points and metal clips that hold the pane in the frame. Replace them if there is any corrosion. If the window is made of wood, the glazier points can be reused if they are still intact.
The next step is to prepare the surface of the remaining frame for re-glazing. Apply a continuous strip compound to the recess with a caulking tool. Use a high quality putty, such as glazier’s compound in cartridge. Dry it out before installing the glass. If the frame has metal clippings, they must be reinstalled too. Install the dividers.
Condensation
Condensation is one of the most common issues that double-glazed windows face, especially in the wintertime. It's usually caused by excessive 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 frequently and enhancing ventilation with extractor fans and running dehumidifiers in order to reduce the amount of moisture. If condensation remains an issue, it's best to call in an expert to get to the bottom of the issue. You can then fix or replace your windows when necessary.
Condensation in a double-glazed glass window is a sign the seal has failed. This is due to the factory applied vacuum seal will be damaged in time, allowing cool air to move between the panes. This can cause the window to get smudged and eventually develop mold if not addressed immediately.
As a quick fix to condensation, you can try using hair dryers to eliminate the excess moisture. But, this is only temporary solution and should only be used as a last option. If the condensation is left for a long time, you might be facing mould or dampness within your home, which must be addressed by a professional.
Professionals can seal your double-glazed window for a better, more durable solution. They'll remove the damaged glass pane, clean the gap and pipe hot air into the area to evaporate any moisture. During this process, they'll also examine for any the presence of mildew, mold or damage growth, and then apply an draught-proofing procedure to ensure your windows are fully functional and energy efficient once again.
Draughts
The rubber seals get worn out over time and cause a draft between your two panes. This is usually a minor problem that can be fixed by replacing the gaskets and this will create a strong and airtight seal once again. This will allow warm air in your home, and the colder air out, saving you money on your energy bills.
Double glazing that is misted may be an indication of blown seals. The unit is comprised of two panes of glass that are separated by the spacer bar to create an insulating space. It is then filled with gas, such as argon, to make the window airtight. If the seal is blown water vapour can enter your space through the gap. This can result in condensation between the glass panes, which is not able to be removed.
Fortunately it is a simple issue to fix and the windows can be replaced quickly by experts who have the appropriate tools and know how to do it right. The professional will employ an instrument designed to push the new seals into place and is generally faster than trying to do it manually. These tools also have a pointed tip which is useful for pushing seals into the corners.
In certain situations, a professional could be able to "reseal' your windows by drilling a small hole into the window and then putting in a special desiccant material or putty. This could be an economical alternative to replacements and it will still give you an effective protection against draughts for your double glazing.
Faulty Hinges
Many people have experienced misted double glazing. It may be caused by a damaged seal or a crack in the glass, or a problem with the frame or mechanism. It is often possible to correct this issue. This typically involves making a seal between the two glass panes. The new seal will prevent leaks, condensation and draughts from occurring.
Contact the company from which you bought your windows and let them know of any issues immediately you spot them. You should notify the company in writing and request confirmation that they have received your notice. If there are any disagreements being resolved, writing everything down will help you prove your case.
In certain situations an expert in window repair may be able to drill a hole in your windows to draw moisture out and create a new seal. However, this is typically only a temporary fix and won't stop moisture from returning. Alternatively, it may be possible to replace the glass unit, to ensure that it is watertight.
It is important to remember that you should only attempt DIY fixes if you have the skills and experience required to do so. Super glue or other DIY solutions could cause more damage over the long term. If you aren't sure what to do, it is always advisable to seek out professional advice.

Broken Seals
Double glazed windows are held in place by seals for windows or insulation gas. A variety of factors can cause them to break, like the weather, age, and power washing, therefore it's crucial to be aware of what the signs 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, and it can also cause the window to appear visually altered. If the seal is damaged it is when any argon or other inert gas will be removed from the glass, further diminishing its insulating properties.
A professional Glazier can replace a damaged window seal with a new one. However, this can be expensive and may not solve the fog issue completely. Some companies offer defogging services, which involve placing the vacuum pump of a specific type inside the window frame to eliminate the moisture and leave the glass clean. However this method isn't foolproof and doesn't replace any inert gases, meaning that the fog can be re-applied.
If the IGU (insulated unit) is beyond repair, a glazier may replace it. This is typically the most cost-effective option and could be a good option when you're seeking a long-term solution. It's best to select an option that provides warranties on replacement windows. This will ensure that any problems you might face are covered. You can be sure that your investment will provide the most effective results. Alternatively, you can try to avoid this problem by selecting a window of high-quality and following the manufacturer's care instructions. This will extend the life of the window and decrease the amount of repairs.
