7 Helpful Tricks To Making The Most Of Your Repairing Double Glazed Windows Repairing Double Glazed Windows

Double-glazed windows "blow", the insulating gas argon escapes, which causes them to lose their energy efficiency. The good news is that damaged double glazing is typically repaired without the need to replace the windows.

The presence of condensation or moisture between your double glazed windows is the most frequent sign that your window seals have failed. It can be easily repaired by a professional saving you the expense of a new window.

Remove the Sash

Double-glazed windows can add value and elegance to your home. They increase the energy efficiency of your home by keeping cold and heat out. In Minnesota's winters that are harsh, having double glazed windows will help reduce your heating bills.

The main difference between single and double glazed windows is that the space between panes of glass is filled with either air or an inert gas, such as argon. This can make a significant difference to the insulation properties of your windows because they block the transfer of heat through the glass. By selecting an inert, low-conductivity gas such as argon, or krypton to fill your windows, you will increase their insulation properties.

Another benefit of double glazed windows is that they are more secure than single pane windows. They are much more resistant to breaking and can be equipped with modern security locking systems. They can be equipped with laminated or toughened glass to make them more secure. Double glazed windows are more sturdy and less prone to sway in the wind or due to vibrations from heavy traffic and are a good choice for older homes.

Double-glazed windows can also be made of low-energy glass, which blocks UV rays that enter your home. This can help ensure that your carpets, paintings and furniture from discoloration. This is particularly helpful when your windows are exposed to direct sunlight for much of the day.

The other reason that homeowners opt to have their old sash windows retrofitted to double glazing is that they are cheaper than the installation of new windows. The interior linings, cladding, and opening mechanisms of your existing windows are not damaged, so the work is less invasive.

As an added bonus the installation of double-glazed windows is much faster than removing and replacing a complete window. This means you can get the benefits of energy efficiency, enhanced security, reduced reflections, and UV damage on your furniture for a less cost.

Take the Glass off

Double-glazed windows differ from single pane windows because they have two glass panes that are separated by an air layer and an air spacer. This creates insulation. This is known as an insulated unit (IGU) which is filled with gases like argon or Krypton, can provide even more insulation. As time passes the units can become damaged and fail to perform properly. It is important to remove any broken glass as securely and swiftly as you can.

Replacing double-glazed windows can be a challenging DIY job that requires specialised tools and techniques. This is why it is usually best left to a professional who will make use of the right safety equipment and follow the correct procedure to prevent injuries.

This is particularly important since double glazed windows can be extremely fragile and can easily break or crack. Wear a respirator, mask and gloves to protect yourself when repairing the window. You should also make sure that the area around the frame is free of debris. In addition, you must put a thick layer of plastic over the area that will be shaved by the deglazing tool to catch the pieces of broken glass and make it easier to take them away.

It's important to check for indications that double-glazed windows aren't working properly. A draughty window is one of the most common symptoms that your IGU has burst and is no longer able to provide proper insulation. You may also notice that the windows are cloudy or have condensation between them.

Double glazing is not just a way to reduce energy costs but also protect your furniture from heat and light. Furniture can deteriorate and break when exposed to sunlight for long periods of time, but double-glazed windows will keep your furnishings out of direct sunlight and will reduce the amount of heat that is brought into your home.

Double glazing that is energy efficient can increase the value of a property. If you're looking to sell your home in the near future having double glazing installed is a smart investment that could draw potential buyers.

Remove the Gaskets

Double glazing is an excellent method of increasing 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 need to be repaired or replaced.

The most important component of the window assembly is the gasket, which is a neoprene or butyl rubber seal that cushions the glazing and offers weather protection. Gasket degrading is the primary cause of leaks and moisture getting into buildings. The seals can be easily replaced without having to replace the entire window.

Gaskets can often be repaired by making them tight and pulling them out. This is easier to do on uPVC frames than on aluminium or timber. If window repair to remove seals manually, you can use a knife designed for builders to cut the seals apart until you are able to grasp it using your fingertips. Once the seal is removed, you can use an alternative seal for an even tighter fit and maximum efficiency.

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


Once all of the beading has been removed after which you can take off the window glass. The gap between the two panes should be between 12 and 12 millimeters, and it's important to fill it with Argon gas for optimum thermal performance. A wider gap can be used to reduce the sound levels, but it will lower the insulation capacity of your windows.

Once the frame has been cleaned it is an ideal idea to spray the frame with window cleaner prior to fitting the DGP. This will prevent the tape from sticking to the glass immediately, giving you time to position it correctly. It's also worth wiping down the rubber seals with an absorbent cloth and warm soapy water to prevent any damage.

Re-seal the Window

If you notice that your double glazed windows are becoming cloudy or there is moisture between the panes, it might be time to have them resealed. These kinds of issues are a clear indication that the inner seal isn't keeping in the insulating gas. It is not unusual to find the rubber seal that keeps in the insulating gases to degrade over time or due to an improper installation.

A professional window specialist will seal the glass unit by placing an entirely new seal around each of the gaps that are insulating. The technician will use a silicone caulk to fill the gaps. This will keep the cold out and warm air in during winter. The caulk will also prevent bugs from getting into your home and it will prevent moisture from entering your home, too.

It is important to know that resealing a double-glazed window is not a DIY job, although it is possible to tackle it yourself. This is a time-consuming and laborious task that requires special tools to remove the old seal, then clean the area and then put in new caulk. It is a good idea to hire an experienced glazier to complete the work to avoid injuries and to ensure that it is done correctly.

In some cases double-glazed windows cannot be repaired and will need to be replaced completely. This could include broken or cracked glass, significant damage to the frame, or serious decay. Talk to a double-glazing professional to determine the best option in these instances.

Often, 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 argon gas for extra insulation. When these treatments fail, moisture can be allowed into the gap between the glass panes, and it can cause condensation. A professional can address this issue by drilling tiny holes in the glass panes and then piping in an agent that dehydrates to eliminate the moisture. The expert will then fill the gap with gas that is insulating, and seal it without the gas from escaping.
