Double Glazed Windows Repairs
There are a variety of reasons your double-glazed windows may require repair such as condensation between panes, to drop or sagged frames. Fortunately, a majority of problems can be addressed.
Try applying lubrication to the hinges, handles and mechanisms of your door or window when it is difficult to open. This is a quick, cheap fix.
Broken Panes
When a window pane breaks it loses its insulating properties and may cause draft. If the dividing muntins are also damaged, it could cause moisture to escape between the glass panes resulting in condensation, mold and mildew and making your home less energy efficient. A window that is damaged should be repaired by an expert to ensure you get a perfect seal and maximum energy efficiency.
First, you will need to remove any broken glass. Begin by putting a drop cloth under the window that has been broken and cutting around the perimeter of the pane using an inexpensive glass cutter (available in most hardware stores). It's recommended to lubricate the cutter with lightweight oil before you begin. This will prevent the glass from shattering too easily. You can then utilize the tool's ball-shaped end to loosen the fragments and they should fall off fairly quickly.
Once the glass is removed, scrape any old glazing compound that has accumulated in the recess of the frame. This will reveal the glazier's points and metal clips that keep the pane in the frame. Replace them if you notice any corrosion. If the window is made of wood the glazier's points could be reused if they're intact.
You'll then need to prepare the surface of the remaining frame to be re-glazed. Apply a continuous strip compound to the recess with the caulking tool. Make use of a high-quality glue such as glazier's compounds that is available in a cartridge, or a standard compound that is sold in a can. It should dry before reinstalling the glass. Reinstall the metal clips if they are on the frame. Install the dividers.
Condensation
Condensation is a frequent issue that double-glazed windows face particularly in wintertime. It's typically caused by excessive humidity in the home as warm air meets cold glass, which condenses into water droplets and settles in the corners of your windows or across the frame. You can stop this from happening by opening your windows more frequently, improving ventilation with extractor fans, and running dehumidifiers. If condensation is still an issue, it's best to contact an expert to get to the bottom of the issue and fix or replace your windows when required.
It's also important to note that condensation on windows with double glazing could be a sign of a leaky seal. This is due to the vacuum seal that was applied by the manufacturer can become degraded over time, allowing cool air to flow between the panes. This could cause the window to become cloudy and then develop mold if it's not addressed immediately.
You can use a hairdryer for a quick way to get rid of excess moisture. This is a temporary fix and should be used only as a final resort. If you let the condensation sit for too long, it may cause dampness or mould within your home. This should be handled by a professional.
Professionals can reseal your double-glazed window to provide a longer-lasting solution. They'll remove the affected piece of glass, clear the gap, and then pipe into hot air to eliminate any lingering moisture. During the process, they will also inspect for any damage or growth of mildew, mould or mildew, and perform an draught-proofing procedure to ensure that your windows are functional and energy-efficient once again.
Draughts
Rubber seals may get worn out over time and cause drafts between your two panes. This is usually a minor problem that can be fixed by replacing the gaskets and this will result in a sturdy and airtight seal once again. This will keep warm air inside your home and cooler air outside. You'll reduce your energy bill.
Misted double glazing is a sign that the seals inside your sealed unit (sometimes called a DGU) have been blown. The unit is comprised of two glass panes filled with argon separated by a spacer to create an airtight window. If the seal has blown it will allow water vapour to pass through your home through the gap, creating condensation between the panes that can't be removed.
Fortunately, this is an easy problem to fix, and windows can be replaced very quickly by specialists with the right tools and know how to do it correctly. The specialist will use a tool designed to push the new seals into position and it is usually faster than doing it manually. These tools also have a pointed end that can be helpful for pushing seals into the corners.
In some cases, a professional could be able to "reseal your windows' by drilling a small hole into the window and adding a special desiccant material or putty. This is a less expensive option than replacing your double glazing and will still provide you with a air-tight system for draughtproofing.
Faulty Hinges
Misted double glazing is a frequent issue that many people face. It may be caused by a broken seal, or a crack in the glass or a problem with the mechanism or frame. It is often possible to correct this issue. This usually involves making a seal between the two glass panes. The new seal will prevent condensation, draughts, and leaks from occurring.
You should contact the company through which you purchased your windows, and tell them of any issues as soon as you spot them. Make sure you do this in writing and request them to confirm that they have received your notice. Making sure that everything is in writing will make it easier to resolve any disputes arise, since it is easier to prove that you actually complained.
In certain situations, a window repair specialist will cut the hole in your windows to draw out moisture and make an entirely new seal. However, this is generally only a temporary solution and will not stop the moisture from returning. It might also be possible to replace just the glass unit, which will make it watertight.
It is important to keep in mind that you should only attempt DIY fixes when you have the skills and know-how required to do so. Super glue or other DIY solutions can result in more damage over the long term. It is always best to seek professional help in case you are unsure of what to do.

Broken Seals
Window seals, or insulation gas fills, keep double-glazed windows in place. They are susceptible to damage due to many elements, including weather conditions, age and power washing. It is crucial to recognize the signs and the best way to repair them.
When a window seal fails it allows moisture to seep in between the two glass panes, creating fog. It's a common problem, and it can cause the window to look visually altered. When the seal is damaged, gas like argon as well as other inert gases are emitted from the window, further decreasing the glass's insulation properties.
A professional glazier can replace a broken window seal with a brand new one. However, this is expensive and may not solve the fog problem entirely. Certain companies offer defogging solutions that involve putting the vacuum pump of a specific type inside the window frame to remove the moisture, leaving the glass free of fog. This method is not foolproof, and it does not replace the inert gasses, which means that the fog can be re-created.
A glazier may also replace the entire IGU (insulated glass unit) when it's beyond repair. This is the most cost-effective option and is a great option if you're looking for a long term solution. However, it's best to select a company with a guarantee for replacement windows to ensure that any issues are protected. This means that you can be assured that you'll get the maximum value for your investment. Alternately, you can try to avoid this problem by choosing a premium window and following the manufacturer's care instructions. This will prolong the lifespan of the window and reduce the amount of repairs.
