Double Glazed Windows Repairs
Double-glazed windows require repair for many reasons, like condensation between the panes, draughts or sagging frames. Most of these problems can be resolved.
Try to lubricate the hinges, handles and mechanisms of your window or door if it is difficult to open. This is usually a simple solution that is quick and easy to fix.
Broken Panes
When a window pane is broken it loses its insulation properties and could cause draft. If the muntins which divide the glass panes are damaged, moisture could leak between them causing condensation and mildew, as well as mould. This can make your home less efficient in energy use. It is best to have a professional repair a broken window to ensure the best seal and energy efficiency.
First, you'll need to remove the broken glass. Begin by putting a drop cloth under the window that has been broken and cutting around the perimeter of the pane using an inexpensive glass cutter (available in most hardware stores). Before starting, you should lubricate the cutter of this tool using a light oil. This will prevent the glass from breaking too easily. Then, you can make use of the tool's ball-shaped tip to loosen the fragments and the glass should break away fairly quickly.
Scrape any old glazing compound out of the frame's recess once the glass has been removed. This will reveal the glazier's points and metal clips that hold the pane in the frame. Replace them if there is any corrosion. If the window is wooden the glazier's gilder's points can be re-used if they're 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. Make use of a premium putty such as glazier's compounds that is contained in a cartridge or conventional compound that is sold in a can. Dry it out before installing the glass. If the frame is made of metal clippings, they must be replaced as well. Reinstall the divider muntins.
Condensation
Condensation is one of the most common issues that double-glazed windows can experience particularly in winter months. It's usually caused by too much moisture in the home where warm air collides with cold glass, which condenses into water droplets and then collects in the corners of your windows or across the frame. It can be prevented by opening your windows more often, improving ventilation through extractor fans, and using dehumidifiers to lower the moisture levels. If condensation is still an issue, it's crucial to get an expert to get to the root of the issue and repair or replace your windows if needed.
It's also important to note that condensation on double-glazed windows could be a sign of a leaky seal. The seal that is applied by the factory can wear out over time and allow cool air to get between the panes. This could lead to fogging of the window and eventually mold growth if it is not addressed promptly enough.
Hairdryers can be used as a quick solution to eliminate excess moisture. But, this is only a short-term solution and should be used as an option last resort. If the condensation has left for a long time you might be facing dampness or even mould in your home, which must be dealt with by a professional.
As a longer-term solution, you can have your double-glazed windows repaired by experts. They'll remove the affected pane of glass, clear the gap and pipe into hot air to eliminate any lingering window and door repair moisture. During the process, they'll also look for any damage or growth of mould, mildew or mildew and apply a draught proofing treatment to ensure that your windows are functional and energy efficient.
Draughts
Rubber seals may wear out over time and create drafts between the two panes. This is often a simple issue that can be resolved by replacing the gaskets and this will create a strong and airtight seal. This will keep warm air inside your home and cooler air outside. You'll save money on your energy bills.
Misted double glazing is a sign that the seals inside your sealed unit (sometimes called a DGU) have been blown. The unit consists of 2 panes of glass separated by a spacer bar to create an insulating gap. Then, it is filled with gas, like argon, to make the window airtight. If the seal is blown it allows water vapour to get into your space through the gap, which will cause condensation between the panes that is not able to be cleaned off.
This is a simple problem to solve, and windows can be easily repaired by professionals using the right tools. The specialist will use tools designed to push the new seals in place and this is normally quicker than doing it manually. These tools have 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 hole into the window and adding the desiccant material, or putty. This is less expensive than replacing your double glazing and still provides you with an effective draught proofing system.
Faulty Hinges
Many people have had misted double glazing. This can be caused by broken or cracked glass frame or even a damaged seal. It is possible to fix this problem. Typically, this is done by making a new seal between the two glass panes. The new seal will help prevent condensation, draughts, as well as leaks.
You should contact the company through which you purchased your windows, and inform them of any issues when you notice them. Make sure you do this in writing, and ask them to confirm that they have received your notice. Writing everything down will make it easier to resolve any disputes arise, because it will be easier to prove that you did complain.
In some instances an expert in window repair will cut the hole in your windows to draw moisture out and create an entirely new seal. This is a temporary fix and won't stop the return of moisture. It is also possible to replace the glass unit, which will make it watertight.
Make sure that you only attempt DIY fixes if your skills and knowledge are adequate. Super glue or other DIY solutions could cause more long-term damage.

Broken Seals
Window seals, or insulation gas fills, are what keep double-glazed windows in place. Many factors can cause them to break, including the weather, age, and power washing, so it's crucial to be aware of what the symptoms are and how to fix them.
If a window seal is damaged it allows humidity to enter between the two glass panes and create fog. This is a common issue that can cause the window appear to be distorted. If the seal fails, gas like argon as well as other inert gases are removed from the window, further diminishing the glass's insulation capabilities.
A professional glazier can replace a broken window seal with a new one. This is costly and may not completely solve the fog issue. Certain companies offer defogging services that involve putting the vacuum pump of a specific type inside the window frame to eliminate the moisture, leaving the glass clear. However, this method is not foolproof and doesn't replace any inert gas, and the fog may return.
A glazier is also able to 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 seeking a long-term solution. But, it's best to choose a company with a guarantee for replacement windows to ensure that any problems are protected. You can be sure that your investment will provide the most effective results. You can also try to get rid of the issue by choosing an item of high-quality and following the care guidelines provided by the manufacturer. This will prolong the life of the window and decrease the number of repairs.
