Double Glazed Windows Repairs
Double-glazed windows require repair for many reasons, like condensation between the panes, draughts, or frames that are sliding. Fortunately, the majority of these issues can be resolved.
Try applying lubrication to the hinges, handles and mechanisms of your window or door in case it is hard to open. This is a quick, cheap solution.
Broken Panes
When a window pane is broken, it loses its insulation properties and could cause a draft. If the dividing muntins also broken it can cause water to leak through the glass panes, resulting in condensation, mildew and mould and making your home less energy efficient. A broken window is best repaired by a professional to ensure you get a proper seal and optimum energy efficiency.
In the beginning, you'll have to remove the broken glass. Start by placing an inexpensive glass cutter from an appliance store beneath the broken pane. It's worth lubricating this tool's cutter with light oil prior to when you begin. This will prevent the glass from breaking too easily. The ball-shaped end of the tool can be used to break the fragments. They should fall off relatively quickly.
After the glass has been removed, scrape off any old glazing compound from the recess area of the frame. This will expose the glazier's point and metal clips that hold the pane in the frame. Replace them if you notice any corrosion. If the window is made of wood the glazier points may be reused if they're still in good condition.
You'll then need to prepare the surface of the frame for re-glazing. Apply a continuous strip of compound to the recess using a 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. If the frame has metal clippings, they should be replaced as well. Finally, put back the divider muntins.
Condensation
Condensation is one of the most common issues that double-glazed windows can experience, especially in the winter months. It's typically caused by too much moisture in the home as warm air meets cold glass, which forms into water droplets and then collects in the corners of your windows or across the frame. This can be avoided by opening windows more regularly and improving ventilation by installing extractor fans, and using dehumidifiers to lower the moisture levels. If condensation persists it is recommended to contact an expert who can identify the issue and repair or replace the windows if needed.
It's also important to remember that condensation on double-glazed windows can actually be an indication of a failing seal. This is because the factory-applied vacuum seal may be damaged over time, allowing cool air to make its way between the panes. This could cause the window to fog up and eventually grow mold if it is not addressed immediately.
For a quick fix to condensation, try using a hairdryer to dry up the excess moisture. This is a temporary solution and should only be used as a final resort. If you leave the condensation for too long, it could lead to mould or dampness in your home. This should be handled by an expert.
Professionals can seal your double-glazed window for a more permanent solution. They'll take off the affected pane of glass, then clean the gaps and pipe in hot air to evaporate any lingering moisture. In this process, they'll also look for signs of damage, mildew or mould growth and carry out a draught-proofing process to ensure that your windows are fully efficient and energy efficient again.
Draughts
The rubber seals get worn out over time and cause drafts between your two panes. It is simple to replace the gaskets, which will create an airtight seal. This will keep warm air inside your home, and colder air outside. You can reduce your energy bills.
Misted double glazing indicates that the seals in the sealed unit (sometimes called a DGU) have blown. The unit is comprised of two panes of argon-filled glass separated by a spacer, creating an airtight window. If the seal has been blown the water vapour will get into your space through the gap. This can result in condensation between the glass panes which is not able to be removed.
This is a straightforward issue to repair, and windows can be easily repaired by professionals using the appropriate tools. The specialist will use a tool designed to push the new seals into position and this is normally quicker than attempting to do it by hand. These tools feature a pointed tip that can be used to push seals into corners.
In certain cases professionals may be able to 'reseal your windows' by drilling a small hole in the window and then putting in the desiccant material, or putty. This can be a more cost-effective solution than replacements, and will provide a reliable draught-proofing system for your double glazing.
Faulty Hinges
Misted double glazing is a frequent issue that many people face. This can be caused by a broken or cracked glass frame or even a damaged seal. It is often possible to fix this problem. This usually involves making a seal between the two glass panes. The new seal will stop condensation, draughts, and leaks from occurring.
You should contact the company from whom you purchased your windows and tell them of any problems as soon as you spot them. It is important to notify the company in writing and request confirmation that they have received your notice. If there is a dispute being resolved, writing everything down will aid in proving your complaint.
In certain situations an expert in window repair may be able to drill a hole in your windows to draw out moisture and make a new seal. This is a temporary fix that won't stop moisture from resurfacing. It is also possible to replace only the glass part, which will make it watertight.
It is important to remember that you should only try DIY fixes when you have the skills and know-how required to be able to do it. Super glue or other DIY solutions can cause more long-term damage. It is best to seek professional help if you are unsure what to do. You can find an expert local to you who can offer double glazing repairs by typing your postcode into the search box on Checkatrade.

Broken Seals
Double glazed windows are held in place by seals on windows or gas. They can be damaged by a variety of elements, including weather conditions, age and power washing. It is crucial to know the symptoms and how to fix them.
When a window seal fails it allows moisture to get into the two glass panes, creating fog. It's a common problem, and it can cause the window to look visually altered. If the seal fails, the inert gases argon and others are emitted from the window, further reducing the glass's insulating qualities.
A damaged window seal can be fixed by replacing it with the new one by a professional glazier. However, this can be costly and might not resolve the fog issue completely. Certain companies offer defogging solutions 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 foolproof and does not replace any inert gases, meaning that the fog may be re-applied.
A glazier may also replace the entire IGU (insulated glass unit) if it is beyond repair. This is typically the most cost-effective option, and could be a good option in the event you're looking for an option that lasts for a long time. It is recommended to choose an option that provides a warranty on replacement windows. This will ensure that any issues you might face are covered. This means that you can be assured that you'll get the maximum value for your investment. You can also try to avoid this problem by selecting a window of high-quality and following the manufacturer's maintenance instructions. This will prolong the life of your window and reduce the need for repairs.
