Double Glazed Windows Repairs
Double-glazed windows require repair for a variety of reasons, including condensation between the panes, draughts or sagging frames. Thankfully, most of these issues can be resolved.
If your window or door is difficult to open, consider oiling the mechanism, hinges and handles. This is usually a cheap solution that is quick and easy to fix.
Broken Panes
When a window pane is damaged it loses its insulation properties and may cause drafts. If the dividing muntins are also damaged, it could cause water to leak through 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 you get a proper seal and optimum energy efficiency.
In the beginning, you'll have to remove the 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 in a majority of hardware stores). Before you begin, make sure to lubricate the cutter of this tool with an oil that is light. This will prevent the glass from breaking too easily. Then, you can utilize the tool's ball-shaped end to loosen the fragments and they should fall off fairly quickly.
Once the glass is removed, scrape any old glazing compound from the recess area of the frame. This will expose the metal clips and glazier's pins that hold the glass in place. Replace them if you notice any corrosion. If the window is constructed of wood the glazier points can be reused if still intact.
The next step is to prepare the surface of the frame to be re-glazed. Apply a continuous strip of compound to the recess with a caulking tool. Use a high-quality putty such as a glazier's compound that is contained in a cartridge, or a standard compound that is sold in a can. Allow it to dry prior to re-inserting the glass. If the frame has metal clippings, these should be removed as well. Finally, install the dividers.
Condensation
Condensation is a common problem that double-glazed windows may experience particularly in winter months. It's usually caused by high levels of moisture in your home. Warm air collides with cold glass and condenses to droplets of water. These droplets then accumulate in the corners and frame of the window. You can avoid this by opening your windows more often and enhancing ventilation by installing extractor fans, and utilizing dehumidifiers. If condensation remains a problem, it's important to call in an expert to get to the root of the issue. You can then fix or replace your windows if necessary.
It's also important to remember that condensation on a double-glazed window can be an indication of a leaky seal. This is due to the vacuum seal that was applied by the manufacturer will be damaged over time and allow cool air to make its way between the panes. This could cause the window to get smudged and eventually develop mold if it is not addressed immediately.
Hairdryers can be used to get rid of excess moisture. This is a temporary fix and should only be used as a last alternative. If the condensation is left for too long you might be facing mold or dampness within your home, which should be addressed by a specialist.
For a more long-term solution you can have your double-glazed windows repaired by professionals. They will remove the affected glass pane, clean the gap and pipe hot air into the area to dry out any moisture. In the process, they'll examine for any damage, mildew or mould growth, and then apply a draught-proofing treatment to ensure that your windows are completely efficient and energy efficient again.
Draughts
Rubber seals may wear down in time and create drafts between your two panes. It's simple to replace the gaskets which will result in an airtight seal. This will keep the warm air inside your home and the colder air out, thereby saving you money on your energy bills.
Double glazing that has mist may be a sign of sealed blown seals. The unit is composed of two panes of glass filled with argon separated by a spacer, creating an airtight window. If the seal has been blown water vapour can enter your room via the gap. This can result in condensation between the glass panes that can't be sucked out.
Fortunately, this is an easy issue to fix and windows can be replaced quickly by experts who have the appropriate tools and know how to do it properly. The professional will employ a tool designed to push the new seals into position and is generally faster than trying to do it manually. These tools feature an edge that can be used to push seals into corners.
In some cases professionals 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 a cheaper solution than replacing your double glazing and will still provide you with a reliable draught proofing system.
Faulty Hinges
Many people have encountered misted double-glazing. It can be caused by a broken seal or a crack in the glass, or an issue with the frame or mechanism. It is often possible to correct this issue. It is usually a matter of making a seal between the two glass panes. The new seal will prevent condensation, draughts and leaks from happening.
If you discover any issues, you must contact the company that sold you your windows. You should notify the company in writing and ask for confirmation that they received your message. If there is a dispute 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 eliminate moisture and create the seal. This is a temporary fix that will not stop the return of moisture. It is also possible to replace the glass unit, which will ensure that it is watertight.

Broken Seals
Double-glazed windows are secured by window seals or insulation gas. Many factors can cause them to break, including age, weather conditions and power washing, so it's important to know what the signs are and how to repair them.
If a window seal is damaged humid air can get between the two panes glass, creating fog. This is a frequent issue that can cause the window appear to be distorted. If the seal is damaged it is when any argon or other inert gas will be removed from the glass, thereby decreasing its insulation properties.
A damaged window seal can be fixed by replacing it with a new one by a professional glazier. However, this is expensive and may not solve the fog problem entirely. Certain companies offer defogging, which involves putting a vacuum pump inside the frame of the window to eliminate moisture and make the glass clear. This method isn't 100% reliable, and it does not replace inert gasses, so the fog could return.
A glazier may also replace the entire IGU (insulated glass unit) when it's beyond repair. This is the most cost-effective solution and can be a great choice if you are looking for a long term solution. It is recommended to choose a company who offers a warranty on replacement windows. This guarantees that any issues you might face are covered. You can be assured that your investment will produce the best results. You can also try to avoid the problem by selecting a high-quality product and following the care guidelines given by the manufacturer. This will extend the lifespan of your window and minimize the need for repairs.
