Double Glazed Windows Repairs
Double-glazed windows require repair for a variety of reasons, including condensation between the panes, draughts or frames that are sliding. Many of these issues are fixable.
If your window or door is difficult to open try oiling the mechanism, hinges and handles. This is usually a simple temporary fix.

If a window pane breaks, it loses its insulating properties and can create draft. If the dividing muntins are also broken, it could cause moisture to leak between the glass panes, resulting in condensation, mildew and mould and making your home less efficient in energy use. A damaged window should be repaired by a professional to ensure you get the correct seal and the optimum energy efficiency.
In the beginning, you'll have to take the broken glass off. Begin by placing a protective drop cloth underneath the window that has been broken and cutting around the edges of the pane with an inexpensive glass cutter (available at most hardware stores). It's worth lubricating this tool's cutter with light oil prior to when you begin. This will stop the glass from shattering too easily. The ball-shaped end of the tool can be used to break the fragments. They should come off relatively quickly.
Once the glass is removed, scrape off any glazing compound that is old from the recess of the frame. This will reveal the glazier's points and metal clips that hold the pane in place. If there's any indication of corrosion, these clips should be replaced with new ones. If the window is made of wood the glazier points can be reused if they're still intact.
The remaining frame will need to be prepared to allow reflazing. Apply a continuous strip of compound to the recess using the caulking tool. Use a high-quality putty, such as Glazier's compound that is contained in a cartridge. Let it dry before installing the glass. If the frame is made of metal clippings, they must be reinstalled too. Finally, reinstall the divider muntins.
Condensation
Condensation can be a problem for double-glazed windows, particularly during winter. It's usually caused by too much moisture in the house as warm air meets cold glass. This then turns into water droplets, and collects in the corners of your windows or across the frame. This can be avoided by opening windows more regularly and enhancing ventilation with extractor fans and running dehumidifiers to reduce moisture levels. If condensation is still an issue, it's best to get an expert to get to the root of the issue and fix or replace your windows when required.
Condensation on a double-glazed window is a sign that the seal has failed. The seals that are applied at the factory may wear away over time and let cool air get between the panes. This can lead to fogging of the window and eventually, mold growth if not dealt with quickly enough.
You can use a hairdryer to get rid of excess moisture. This is only a temporary solution and should only be used as a final alternative. If you let the condensation sit for too long, it may cause dampness or mould in your home. This issue should be dealt with by a professional.
Professionals can seal your double-glazed window for a more permanent solution. They'll take off the affected glass pane, clean the gap and pipe hot air into the area to evaporate any moisture. During the process, they'll also check for any signs of damage or growth of mildew, mould or mildew and apply a draught proofing treatment to ensure that your windows are fully functional and energy-efficient once again.
Draughts
Rubber seals can get worn out over time and create a draft between your two panes. This is typically a simple problem that can be fixed by replacing the gaskets, and this will result in a solid and airtight seal. This will keep warm air inside your home, and cooler air outside. You'll save money on your energy bills.
Misted double glazing is a sign that the seals in the sealed unit (sometimes called a DGU) have blown. The unit is comprised of two panes of glass separated by the spacer bar to create an insulating space. It is then filled with gas, like argon, to make the window airtight. If the seal has been blown, water vapour will enter your room via the gap. This can result in condensation between the glass panes, which can't be sucked out.
This is a straightforward issue to fix, and windows can be easily replaced by experts using the right tools. The specialist will use an instrument designed to push the new seals in place and it is usually faster than doing it manually. These tools feature an angled tip that can be used to push the seals into corners.
In certain cases professionals could be able to "reseal your windows' by drilling a small hole in the window and then putting in the desiccant material, or putty. This could be more cost-effective than replacements and it will still offer a reliable draught-proofing system for your double-glazed windows.
Faulty Hinges
Misted double glazing is a typical issue that many people face. It can be caused by a cracked or broken glass or frame or even a damaged seal. The good news is that it can be easily fixed. Normally, this involves creating an entirely new seal between the two panes of glass. The new seal will prevent condensation, draughts, and leaks.
Contact the company through which you purchased your windows, and tell them of any problems as soon as you notice them. It is important to notify the company in writing and demand confirmation that they received your notification. Making sure that everything is in writing will help later on should any disputes arise, since it will be easier to prove that you did indeed complain.
In some instances an expert in window repair may be able to drill a hole in your windows to draw out moisture and create a new seal. This is a temporary fix that won't stop moisture from returning. It is also possible to replace the glass unit itself, to ensure that it is watertight.
It is crucial to remember that you should only experiment with DIY fixes if you have the skills and experience required to do so. Super glue or other DIY solutions can result in more long-term damage. It is best to seek help from a professional in case you are unsure of what to do.

Broken Seals
Double glazed windows are held in place by seals on windows or gas. They are susceptible to damage due to various factors, including weather conditions, age, and power washing. It is crucial to know the symptoms and how to fix them.
If a window seal is damaged, it allows humid air to seep in between the two glass panes, creating fog. It's a common problem, and can cause the window to appear visually distorted. Once the seal fails, gas like argon as well as other inert gases are emitted from the window, further reducing the glass's insulating qualities.
A broken window seal can be fixed by replacing it with a the new one by a professional glazier. However, this is expensive and may not resolve the fog issue completely. Certain companies offer defogging, which involves putting an air-pump inside the frame of the window to remove moisture and make the glass clear. This method is not foolproof, and it does not replace the inert gasses, meaning that fog may come back.
If the IGU (insulated unit) is damaged beyond repair, a glazier may replace it. This is the most cost-effective option and can be a great choice if you are seeking a long-term solution. It's best to select an option that provides a warranty on replacement windows. This will ensure that any problems that you might encounter are covered. You can be assured that your investment will yield the best results. You can also try to avoid the problem by selecting the best quality product and following the care guidelines given by the manufacturer. This will extend the lifespan of your window and reduce the need for repairs.
