10 Double Glazed Windows Repairs Tricks All Experts Recommend
Double Glazed Windows Repairs
There are a variety of reasons your double-glazed windows may require repairs, from condensation between panes to draughts and dropped or sagged frames. Many of these issues can be solved.
If your window or door is difficult to open, try oiling the mechanism, hinges and handles. This is usually a simple solution that is quick and easy to fix.
When a window pane is damaged and shattered, it loses its insulation properties and could cause draft. If the dividing muntins are also damaged, it could cause water to escape between the glass panes resulting in condensation, mold and mildew and making your home less efficient in energy use. A damaged window should be repaired by a professional to ensure you get a perfect seal and optimum energy efficiency.
First, you will need to remove any broken glass. Start by placing a protective drop cloth underneath the window that has been broken and scoring around the perimeter of the pane with an inexpensive glass cutter (available in a majority of hardware stores). Before you start, lubricate the cutter of this tool with a light oil. This will help prevent the glass from breaking too easily. The ball-shaped end of the tool can be used to break the fragments. They should fall off quite quickly.
Scrape any old glazing compound from the recess of the frame after the glass has been removed. 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 wooden the glazier's points could be used again if they're in good condition.
The surface of the remaining frame needs to be prepared to allow reflazing. Apply a continuous strip of compound to the recess with the caulking tool. Use a high-quality putty like glazier's compound that is contained in a cartridge, or a standard compound that is sold in a can. Let it dry before inserting the glass. Reinstall the metal clips, if they are on the frame. Install the dividers.
Condensation
Condensation is a common problem that double-glazed windows may experience particularly in wintertime. It's usually caused by excessive humidity in the home where warm air collides with cold glass, which forms into water droplets and settles 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 persists, you should call an expert who will be able to pinpoint the issue and fix 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 could wear away over time and allow cool air to pass between the panes. This could lead to fogging of the window and eventually, mold growth if not addressed promptly enough.
You can use a hairdryer as a quick solution to get rid of excess moisture. This is a temporary fix and should only be used as a last alternative. If you allow the condensation to sit for too long, it may lead to mould or dampness in your home. This issue should be dealt with by an expert.
As a longer-term solution, you can have your double-glazed windows resealed by professionals. They'll remove the damaged glass pane and clean the gap. They'll then pipe hot air into the space to dry out any moisture. During the process, they will also check for any signs of damage or growth of mould, mildew or mildew and apply an draught-proofing procedure to ensure that your windows are functional and energy efficient.
Draughts
Rubber seals may get worn out over time and cause drafts between the two panes. It's an easy fix to replace the gaskets which will result in an airtight seal. This will keep warm air inside your home and colder air outside. You will save money on your energy bill.
Misted double glazing is a sign the seals of the sealed unit (sometimes called a DGU) have blown. The unit is comprised of two panes of glass that are separated by a spacer bar to create an insulating gap. Then, it is filled with gas, like argon for example, to make the window airtight. If the seal is blown water vapour can enter your space through the gap. This will create condensation between the glass panes that is not able to be removed.
Fortunately, this is an easy issue to fix and the windows can be replaced quickly by professionals with the right tools and know how to do it right. The specialist will use an instrument designed to push the new seals in place and this is normally quicker than doing it by hand. These tools also come with a pointed end that can be helpful for pushing the seals into the corners.
In some cases professionals might be able to "reseal' your windows by drilling a small hole into the window and then putting in an adsorbent material or putty. This can be an economical alternative to replacements and it will still provide a reliable draught-proofing solution for double glazing.
Faulty Hinges
Many people have encountered misted double-glazing. It can be caused by a broken or cracked glass frame or even a damaged seal. The good news is that this can often be repaired. This usually involves creating a seal between two glass panes. The new seal will stop condensation, draughts, and leaks from happening.
If you discover any problems, you should contact the company that sold you your windows. It is important to notify the company in writing and request confirmation that they received your notification. If there are any disputes being resolved, writing everything down will aid in proving your case.
A window repair specialist could drill a hole between your windows to remove moisture and make a seal. However, this is generally only a temporary fix and won't stop the moisture from returning. It is also possible to replace the glass, which would make it watertight.
Remember that you should only attempt DIY fixes only if your skills and experience are adequate. Utilizing super glue or any other type of DIY solution can cause more harm in the long term. If you aren't sure what to do, it is always recommended to seek professional advice.

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 the weather, age, and power washing, therefore it's important to know what the symptoms are and how to fix them.
When a window seal breaks, it allows humid air to seep in between the two glass panes, creating fog. This is a frequent issue that can also make the window appear distorted. Once the seal fails, any argon or other inert gas is lost from the glass, further decreasing its insulation properties.
A professional glazier can repair a damaged window seal with a new one. This is costly and may not completely solve the fog issue. Some companies offer defogging which involves placing an air-pump inside the window frame to eliminate moisture and make the glass clear. However, this method is not 100% reliable and cannot replace any inert gases, meaning that the fog can return.
A glazier can also replace the entire IGU (insulated glass unit) if it is beyond repair. This is usually the most cost-effective option and could be a good option if you're seeking a long-term solution. It's best to select an option that provides a warranty on replacement windows. This will ensure that any issues you might face are covered. This way, you can rest at ease knowing that you'll get most out of your investment. You can also try to get rid of the issue by choosing the best quality product and following the care guidelines provided by the manufacturer. This will prolong the life of your window and reduce the need for repairs.
