Double Glazed Windows Repairs
Double glazed windows can need repair for a variety of reasons, like condensation between the panes, draughts or frames that are sagging. Most of these problems can be resolved.
If your window or door is difficult to open, try oiling the hinges, mechanism and handles. This is usually a simple solution that is quick and easy to fix.
Broken Panes
If a window pane breaks, it loses its insulation properties and can create draft. If the dividing muntins also broken, it could cause moisture to escape between the glass panes resulting in condensation, mold and mildew and making 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 optimum energy efficiency.
The first step is to take out any broken glass. Begin by putting a drop cloth under the broken window, and then cutting around the edges of the pane using an inexpensive glass cutter (available in a majority of hardware stores). It's worth lubricating this tool's cutter with a light oil before you begin. This will prevent the glass from breaking too easily. The ball-shaped end of the tool can be used to loosen the fragments. They should come off relatively quickly.
After the glass has been removed, scrape away any glazing compound that is old from the recess of the frame. This will reveal the metal clips and glazier's pins that keep the glass in the frame. If there's evidence of corrosion, the clips must be replaced with new ones. If the window is made of wood, the glazier's points can be reused if they're intact.
The surface of the remaining frame must be prepared to allow re-glazing. Using a caulking gun, apply a continuous strip of compound along the inside edge of the recess. Make use of a premium putty such as a Glazier's compound that is contained in a cartridge. Allow it to dry prior to re-inserting the glass. If the frame has metal clippings, these should be replaced as well. Install the dividers.
Condensation
Condensation can be a problem for double-glazed windows, particularly during the winter. This is usually caused by high levels of moisture in your home. Warm air collides with cold glass and condenses into water droplets. They then settle in the corners or frame of the window. You can avoid this by opening your windows more often and improving ventilation with extractor fans, and utilizing dehumidifiers. If condensation is still present it is recommended to contact an expert who will be able to pinpoint the issue and repair or replace the windows if needed.
Condensation on a double-glazed glass window is a sign that the seal has failed. This is due to the factory applied vacuum seal will break down over time and allow cool air to flow between the panes. This could lead to fogging of the window and eventually mold growth if it is not addressed quickly enough.
Hairdryers can be used for a quick way to get rid of excess moisture. This is a temporary solution and should only be used as a last option. If you let the condensation sit for too long, it could lead to mould or dampness within your home. This should be handled by an expert.
Professionals can reseal double-glazed windows to provide a longer-lasting solution. They'll take off the affected glass pane and clean the gap. They will then pipe hot air into the space to eliminate any moisture. During the process, they'll also look for any damage or growth of mildew, mould or mildew and then perform an air draughtproofing treatment to ensure that your windows are functional and energy-efficient once again.
Draughts
The rubber seals get worn out over time and cause drafts between your two panes. It's a simple fix to replace the gaskets which will create an airtight seal. This will keep warm air inside your home, and the colder air outside, saving you money on your energy bills.
Double glazing that has mist may be a sign of blown seals. The unit consists of 2 panes of glass separated by a spacer bar to create an insulating space. It is then filled with gas, such as argon to make the window airtight. If the seal has blown it will allow water vapour to enter your room through the gap, which will cause condensation between the panes which can't be removed.
This is a simple problem to solve and windows can be quickly repaired by professionals using the right tools. The professional will employ an instrument designed to push the new seals in place and is generally faster than trying to do it manually. The tools have a pointed tip that can be used to push seals into corners.
In certain situations an expert could be able to "reseal your windows' by drilling a small hole in the window and adding a special desiccant material or putty. This is a cheaper solution than replacing your double-glazed windows and will still provide you with a reliable Draught-proofing system.
Faulty Hinges
Many people have had misted double glazing. It could be caused by a broken or cracked glass frame or even a damaged seal. The good news is that this can often be solved. This typically involves making a seal between the two glass panes. The new seal will prevent condensation, draughts, and leaks from happening.
If you discover any problems, you should contact the company that sold you the windows. You should inform the company in writing and ask for confirmation that they have received your notice. If there are any disagreements being resolved, writing everything down will make it easier to prove your claim.
A window repair professional might be able to drill a hole in the gap between your windows to remove moisture and form an airtight seal. This is a temporary fix that won't stop the return of moisture. It is also possible to replace the glass unit, to ensure that it is watertight.

Broken Seals
Window seals, or insulation gas fills, are what hold double-glazed windows in place. There are a variety of reasons that can cause them to break, including age, weather conditions and power washing. It's essential to be aware of what symptoms are and what to do to fix them.
When a window seal fails, humid air can seep between the two panes glass, causing fog. It's a frequent issue and can cause the window to appear visually altered. If the seal fails, the inert gases argon and others are removed from the window, further decreasing the glass's insulation properties.
A professional Glazier can replace a damaged window seal with a new one. However, this could be expensive and may not resolve the fog issue completely. Certain companies offer defogging, which involves placing an air-pump inside the frame of the window to eliminate moisture and make the glass clear. This method is not foolproof, and it does not replace the inert gasses, which means that the fog could 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 method and is a good choice if you are looking for a long term solution. However, it's best to select a company that offers a warranty for replacement windows to ensure that any issues are covered. This way, you can rest assured that you'll get the maximum value for your investment. You can also try to avoid this problem by choosing a high-quality window and following the manufacturer's maintenance instructions. This will help to prolong the lifespan of your window and decrease the need for repairs.
