15 Repairing Double Glazed Windows Benefits Everyone Needs To Be Able To
Repairing Double Glazed Windows

Double-glazed windows "blow", the insulating gas argon escapes, causing them to reduce their energy efficiency. The good news is, blown double glazing is often repaired without needing to replace the windows.

The presence of condensation or moisture between your double glazed windows is the most frequent indication that the seals on your windows are failing. It can be easily repaired by a professional, which will save you the cost of a new window.

Remove the Sash

Double-glazed windows are a fantastic way to enhance the look and value of your home. They also improve your home's energy efficiency and keep the cold out and the heat in. With Minnesota's harsh winters, having double-glazed windows will help you save on heating costs.

The main difference between single and double glazed windows is the gas that fills the space between panes of argon or air. This can make a significant difference to the insulation properties of your windows, as it prevents heat from moving through the glass. Selecting an inert gas that has low thermal conductivity, such as argon or krypton, helps to increase the insulating properties of your windows more.

Another benefit of double glazed windows is that they are much more secure than single paned windows. They are less secure and resistant to breaking. They can also be equipped with modern security locking systems. They can be equipped with laminated or toughened glass to make them safer. Double-glazed windows are more durable and less likely than single-glazed windows to rattle or vibrate in the winds. They are an excellent choice for older homes.

In addition, double glazed windows can be constructed with low-energy glass that reduces UV rays entering your home. This will ensure that your carpets, paintings, and furnishings from fading. This is especially useful if you have windows that are in direct sunlight for the majority of the time of the day.

Retrofitting a sash window that is old with double glazing is cheaper than purchasing new windows. The cladding and internal linings of your old windows are intact, making the job much less demanding.

As an added bonus, the process of installing double glazed windows is much quicker than removing and replacing a window in its entirety. This means you can benefit from energy efficiency, enhanced security, and less glare and UV damage to your furnishings at a lower cost.

Take the Glass off

Double glazed windows are different from single pane windows as they have two glass panes separated by an air layer and a spacer. This provides insulation. The insulated glass unit (IGU) can be filled with gases such as argon or krypton for even better insulation. As time passes, these units can become damaged and fail to perform properly. It is crucial to take away any broken glass as safe and quickly as possible.

It can be difficult to replace double-glazed windows on your own. You will need specialised tools and expertise. It is best to leave this job to a professional who will use the right safety equipment and follow the right procedure to avoid injuries.

It is important to do this because double-glazed windows are very fragile and can easily crack or break. To protect yourself while repairing your window, put on gloves with protection and wear a mask or respirator. Make window repair that the area around the window frame is free of debris and clean. Also, you should place a thick piece of plastic over the place where the deglazing tool is going to score to take any broken pieces of glass and make them easier to remove.

In addition to replacing broken glass, it's essential to find indications that your double-glazed windows aren't functioning correctly. A draughty window is among of the most frequently observed signs that your IGU has burst and is no longer providing the proper insulation. You can also notice if the windows are cloudy or there is condensation between them.

Double glazing isn't just an opportunity to save money on energy bills but also to shield your furniture from heat and light. Furniture can break and fade if exposed to sunlight for long periods of time, but double-glazed windows will protect your furniture from direct sunlight and reduce the amount of heat that is brought into your home.

Apart from being a great method to cut down on electric bills, effective double glazing can also enhance the value of your home. Double glazing is a great investment if you intend to sell your home in the near future.

Remove the gaskets

Double glazing is an excellent way to increase the energy efficiency of your home, but it can wear out over time. Double glazed windows that show visible damage, are draughty or are susceptible to condensation should be repaired or replaced.

The gasket is a key component of the window. It is a neoprene-based rubber seal that cushions and shields the window from the elements. Gaskets that are damaged are the main reason for leaks and water infiltration into buildings. Fortunately, the seals can be replaced without replacing the entire window.


Gaskets are often repaired by making them tight and removing them. It is much easier to repair uPVC frames rather than aluminum or timber. If you're not able to remove the seals manually it's best to use a builder's knife to pry away the seal until you are able to grasp it with your fingers. After the seal has been removed, you can put in an alternative seal for an even tighter fit and maximum effectiveness.

Once the seals have been replaced, the window beading needs to be removed. You can employ a lead or putty knife to remove the window beading. The blade of the knife between the frame and the bead in the middle of the longest bead. This will give you the maximum leverage to separate the bead from the frame.

After removing the beading, you can take off the window glass. The gap between the two panes must be about 12mm and it's crucial to fill the gap with Argon gas to ensure optimal thermal performance. It is possible to increase the gap between your panes to reduce noise, but this will decrease the insulating properties of your windows.

It's a good idea to spray the window cleaner on the frame after it has been cleaned. This will help the DGP stick better. This will prevent the tape from sticking to the glass instantly and will allow you to position it correctly. To avoid any damage, it's worth wiping the seals of the rubber with a soft cloth and warm soapy lukewarm water.

Re-seal the window

It could be time to replace the seal on your double-glazed windows if notice that they're fogged up or have moisture between them. These types of problems indicate that the seal in the interior isn't able to hold in the insulating gas. This is not uncommon; the rubber that keeps in the insulating gas may fail due to wear and tear or poor installation.

A skilled window specialist will seal the glass unit by placing a new seal around each of the individual gaps that are insulating. The technician will fill the gaps with silicone caulk. This will keep the cold out and warm air in during winter. The caulk will also stop insects from entering your home, and will prevent moisture from getting into your home as well.

Re-sealing double glazed windows is not a DIY-friendly task. But it is possible. This is a lengthy and laborious job that requires special tools to get rid of the old seal, then clean the area, and then apply a new caulk. It is a good idea to call in a professional glazier for the job to avoid injury and to ensure that the work is done correctly.

In some cases, a double-glazed glass window is not repairable and must be replaced completely. This can be caused by broken or cracked glass, severe damage to the frame or severe decay. It is recommended to consult an expert in double glazing to find out what the best solution is in these circumstances.

Oftentimes, the misting of windows is a sign that the treatment of the glass in the factory has failed. The factory will treat the window with a low-emissivity coating to reflect heat away. Additionally, it may pump in an argon gas to provide additional insulation. When these treatments fail, moisture gets to enter the space between the glass panes and it can cause condensation. A professional can solve this issue by drilling tiny holes into the glass panes and then piping in a dehydrating agent to get rid of the moisture. The professional will then fill the gap with a new gas insulating the area and seal it up without letting any gas escape.
