Double Glazed Windows Repairs
There are a variety of reasons your double glazed windows might require repairs, from condensation between panes, to dropping or sagging frames. Fortunately, a majority of problems can be addressed.
Try to lubricate the hinges, handles and mechanisms of your window or door if it is difficult to open. This is a simple, affordable fix.
Broken Panes
When a window pane is damaged, it loses its insulation properties and may cause drafts. If the muntins which divide the glass panes also broken, moisture can be leaking between them, causing condensation or mildew, or mould. This will make your home less efficient in energy use. A broken window is best repaired by an expert to ensure that you get a proper seal and maximum energy efficiency.
Firstly, you'll need to remove the broken glass. Start by placing an inexpensive glass cutter in 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 stop the glass from shattering too easily. You can then use the tool's ball-shaped end to loosen the pieces and they should fall away quickly.
Scrape any old glazing compound from the frame's recess once the glass is removed. This will expose the glazier's clips and pins that keep the glass in place. Replace them if there's any corrosion. If the window is wooden the glazier's points could be re-used if they're still in good condition.
The remaining frame needs to be prepared to allow re-glazing. With a caulking gun apply a continuous ribbon of compound around the inside edge of the recess. Use a high-quality putty, such as a Glazier's compound in cartridge. Allow it to dry prior to installing the glass. Reinstall the metal clips, if they are attached to the frame. Install the dividers.
Condensation
Condensation is one of the most common issues that double-glazed windows can experience particularly in wintertime. It's typically caused by too much moisture in the home 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 your windows more often and enhancing ventilation with extractor fans, and using dehumidifiers in order to reduce the amount of moisture. If condensation is still 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.
It's also important to know that condensation on double-glazed windows can actually be an indication of a failing seal.

This could cause the window to become cloudy and eventually develop mold if it is not addressed immediately.
You can use a hairdryer to get rid of excess moisture. This is a temporary solution and should only be used as a last option. If the condensation is left for a long time it may be experiencing dampness or even mould in your home, which must be addressed by a specialist.
As a longer-term solution, you can have your double-glazed windows repaired by professionals. They'll take off the affected glass pane, clean the gap and pipe hot air into the space to eliminate any moisture. During the process, they will also check for any damage or growth of mildew, mould or mildew, and perform a draught proofing treatment to ensure that your windows are fully efficient and energy efficient once more.
Draughts
As time passes by, the rubber seals around the edges of your insulated glass can be damaged and create a draught in space between the two panes. This is typically a simple issue that can be resolved by replacing the gaskets and this will result in a solid and airtight seal once again. This will keep warm air inside your home and cooler air out. You can save money on your energy bills.
Double glazing that has mist may be a sign of sealed blown seals. The unit is made up of two panes of glass separated by a spacer bar to create an insulating gap and then filled with gas, such as argon for example, to make the window airtight. If the seal has been blown it will allow water vapour to enter your room through the gap, creating condensation between the panes which is not able to be cleaned off.
Fortunately it is a simple issue to fix and the windows can be replaced very quickly by professionals who have all the right tools and know how to do it properly. The specialist will use an instrument designed to push the new seals in place and is generally faster than attempting to do it by hand. These tools also come with a pointed end which is useful to push the seals into the corners.
In certain situations, a professional could be able to "reseal' your windows by drilling a small opening into the window and then adding the desiccant material, or putty. This is more cost-effective than replacements and it will still provide a reliable protection against draughts for your double-glazed windows.
