Double Glazed Windows Repairs
Double-glazed windows may require repair for many reasons, like condensation between the panes, draughts or frames that are sliding. Thankfully, most of these issues can be fixed.
Try applying lubrication to the hinges, handles, and mechanism of your door or window in case it is hard to open. This is a quick and inexpensive solution.
Broken Panes
When a window pane is broken, it loses its insulation properties and may cause draft. If the dividing muntins are damaged, it could cause moisture to leak through the glass panes resulting in condensation, mould and mildew and making your home less efficient in energy use. It is recommended to hire a professional repair a broken window in order to get the best seal and energy efficiency.
The first step is to take out any broken glass. Begin by putting a drop cloth beneath the broken window and then cutting around the perimeter of the pane using an inexpensive glass cutter (available at most hardware stores). It's recommended to lubricate the cutter with a light oil before you begin. This will stop the glass from breaking too easily. The ball-shaped end of the tool can be used to loosen the fragments. They should come off fairly quickly.
Once the glass is removed, scrape off any glazing compound that is old from the recess area of the frame. This will expose the metal clips and glazier's pins that keep the glass in the frame. If there's any sign of corrosion, these clips should be replaced with new ones. If the window is made of wood the glazier points may be reused if they're still in good shape.
The remaining frame will need to be prepared to allow reflazing. With a caulking gun apply a continuous strip of compound around the inner edge of the recess. Use a high quality putty, such as glazier’s compound in cartridge. Allow it to dry before re-inserting the glass. Reinstall the metal clips, if they are on the frame. Finally, install the dividers.
Condensation
Condensation is a concern for double-glazed windows, especially during the winter. It's typically caused by too much moisture in the house as warm air meets cold glass. This then condenses into water droplets and then collects in the corners of your windows or across the frame. It can be prevented by opening windows more frequently, improving ventilation through extractor fans and running dehumidifiers to lower the moisture levels. If condensation continues to occur it is recommended to contact a professional who can diagnose the problem and repair or replace the windows if needed.
Condensation in a double-glazed glass window is a sign that the seal has failed. The seals that are applied at the factory can wear out over time and allow cool air to get between the panes. window repairs can cause the window to fog up and then develop mold if it is not addressed immediately.
As a quick fix for condensation, try using a hairdryer to dry up the excess moisture. This is only a temporary solution and should be used only as a last resort. If the condensation has been left for too long it could be looking at mould or dampness in your home, which must be addressed by a professional.
Professionals can reseal double-glazed windows for a more permanent solution. They'll remove the affected piece of glass, then clean the gap and pipe into hot air to eliminate any lingering moisture. During the process, they'll examine for any damage, mildew or mould growth, and then apply a draught-proofing treatment to ensure your windows are functional and energy efficient once again.
Draughts
The rubber seals get worn out in time and create drafts between your two panes. This is usually a minor problem that can be fixed by re-installing the gaskets and this will result in a solid and airtight seal. This will keep warm air in your home, and the colder air outside, saving you money on your energy bills.
Double glazing that is misted could be a sign of blow-blown seals. The unit is made up of two panes of glass filled with argon separated by a spacer, creating an airtight window. If the seal has been blown, water vapour will enter your room via the gap. This will create condensation between the glass panes that cannot be removed.
This is a straightforward issue to solve, and windows can be swiftly replaced by specialists with the right tools. The expert will employ a tool designed to push the new seals into position and is generally faster than doing it by hand. The tools also come with a pointed end which can be useful to push the seals into the corners.
In certain situations an expert may 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 less expensive option than replacing your double-glazed windows and will still provide you with a 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 it can be easily repaired. Normally, this involves making a new seal between the two panes of glass. The new seal will prevent leaks, condensation and draughts from occurring.
Contact the company through which you bought your windows and tell them of any problems when you spot them. It is important to notify the company in writing and demand confirmation that they have received your notice. Making sure that everything is in writing will be helpful later if any disputes arise, because it is easier to prove that you actually complained.
A window repair professional might be able to drill a hole in the gap between your windows in order to eliminate moisture and form the seal. However, this is typically only a temporary fix and won't stop the moisture from returning. It is also possible to replace the glass unit itself to ensure that it is watertight.

Broken Seals
Window seals, also known as insulation gas fills, keep double-glazed windows in place. There are a variety of reasons that can cause them to break, like weather conditions, age and power washing, therefore it's crucial to be aware of what the symptoms are and how to fix them.
When a window seal fails, it allows humid air to get into the two glass panes and create fog. This is a common issue that can cause the window appear disfigured. Once the seal fails, gas like argon as well as other inert gases are lost from the window, further diminishing the glass's insulation capabilities.
A professional glazier can repair a damaged window seal with a new one. This is costly and may not solve the fog issue. Some companies offer defogging which involves putting a vacuum pump inside the window frame to remove moisture and clear the glass. However, this method is not 100% reliable and cannot replace any inert gas, and the fog may return.
A glazier may also replace the entire IGU (insulated glass unit) if it is beyond repair. This is usually the most cost-effective solution and could be a good option in the event you're looking for an option that lasts for a long time. But, it's best to select a company with a guarantee for replacement windows to ensure that any problems are covered. This means that you can be assured that you'll get the most value from your investment. You can also try to avoid this issue by choosing a premium window and following the manufacturer's maintenance instructions. This will extend the life of your window and decrease the need for repairs.
