Double Glazed Windows Repairs
There are many reasons why your double-glazed windows may need repairs such as condensation between panes to draughts and dropped or sagged frames. Thankfully, most of problems can be addressed.
Try applying lubrication to the hinges, handles, and mechanism of your window or door if it is difficult to open. This is a quick and inexpensive solution.
Broken Panes
When a window pane is damaged it loses its insulation properties and can cause a draft. If the dividing muntins are broken, it could cause moisture to leak between the glass panes resulting in condensation, mold and mildew and making your home less efficient in energy use. It is recommended to hire a professional repair the damaged window to ensure the best seal and energy efficiency.
The first step is to take out any broken glass. Begin by placing a protective drop cloth underneath the broken window, and then cutting around the perimeter 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 prevent the glass from breaking too easily. The ball-shaped tip of the tool can be used to loosen the fragments. They should fall off fairly quickly.
Scrape any old glazing compound out of the recess of the frame after the glass has been removed. This will reveal the glazier's facets and the metal clips that hold the pane in the frame. Replace them if there's any corrosion. If the window is made of wood the glazier points may be reused if still in good condition.
The next step is to prepare the surface of the remaining frame for re-glazing. With a caulking gun apply a continuous strip of compound along the inside edge of the recess. 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. Let it dry before installing the glass. If the frame is made of metal clippings, they should be replaced as well. Finally, put back the divider muntins.
Condensation
Condensation can be a problem for double-glazed windows, especially in winter. It's typically caused by too much moisture in the home where warm air collides with cold glass, which then forms into water droplets and then collects in the corners of your windows or across the frame. This can be prevented by opening windows more regularly, improving ventilation through extractor fans and running dehumidifiers to reduce moisture levels. If condensation remains an issue, it's crucial to call in an expert to get to the root of the issue. You can then fix or replace your windows when needed.
It's also important to note that condensation on double-glazed windows could be a sign of a failing seal. The seal that is applied by the factory could wear away over time and let cool air get between the panes. This can cause fogging of the window, and eventually mold growth if not addressed quickly enough.
A hairdryer can be used to get rid of excess moisture. This is a temporary fix and should be used only as a final option. 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 reseal your double-glazed window for a better, more durable solution. They'll remove the damaged glass pane and clean the gap. They will then pipe hot air into the space to dry out any moisture. During this process, they'll also check for damage, mould or mildew growth and carry out a draught-proofing treatment to ensure your windows are completely operational and energy efficient again.
Draughts
The rubber seals wear out in time and create a draft between your two panes. It's an easy fix to replace the gaskets which will create an airtight seal. This will keep warm air in your home and the colder air outside, saving you money on your energy bills.
Misted double glazing is a sign that the seals inside your sealed unit (sometimes called a DGU) have blown. The unit is composed of two glass panes filled with argon separated by a spacer, creating an airtight window. If the seal is blown it allows water vapour to get into your space through the gap, creating condensation between the panes which can't be removed.
This is a simple issue to repair, and windows can be easily repaired by professionals using the proper tools. The specialist will use a tool designed to push the new seals into place and it is usually faster than attempting to do it manually. These tools have an edge that can be used to push the seals into corners.
In some cases professionals might be able to "reseal your windows' by drilling a small opening into the window and then putting in an adsorbent material or putty. This could be more cost-effective than replacements, and will provide a reliable draught-proofing solution for double glazing.
Faulty Hinges
Misted double glazing is a frequent problem that many people encounter. It can be caused by cracked or broken glass or frame or even a damaged seal. The good news is that this can often be solved. It is usually a matter of making a seal between the two glass panes. The new seal will prevent leaks, condensation and draughts from happening.
Contact the company from which you purchased your windows, and let them know of any problems when you discover them. You should notify the company in writing and demand confirmation that they have received your notice. If there is a dispute, having everything in writing will make it easier to prove your case.
In some instances, a window repair specialist will cut the hole in your windows to draw out moisture and make a new seal. This is a temporary fix that will not stop moisture from resurfacing. It might also be possible to replace just the glass unit, which will make it watertight.
It is crucial to remember that you should only try DIY fixes if you have the skills and experience required to do so. Super glue or other DIY solutions can cause more permanent damage. It is recommended to seek out professional assistance in case you are unsure of what to do.

Broken Seals
Window seals, also known as insulation gas fills, are what hold double-glazed windows in place. They are susceptible to damage due to various factors, including weather conditions, age and power washing. It is important to recognize the signs and how to fix them.
If a window seal fails, humid air can seep between the two panes of glass, causing fog. This is a common problem that can make the window appear distorted. If the seal is damaged it is when any argon or other inert gas is lost from the glass, diminishing its insulating properties.
A professional Glazier can replace a damaged window seal with a brand new one. This can be expensive and may not completely solve the fog issue. Some companies offer defogging, which involves putting a vacuum pump inside the window frame in order to remove moisture and make the glass clear. This method isn't 100% reliable, and it does not replace inert gasses, meaning that fog could come back.
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 choose a firm that offers a warranty for replacement windows to ensure that any issues are covered. You can be certain that your investment will provide the best results. You can also avoid this issue by choosing an item of high-quality glazing repairs and following the maintenance instructions provided by the manufacturer. This will prolong the life of the window and reduce the amount of repairs.
