A Step-By-Step Guide For Choosing Your Repairing Double Glazed Windows
Repairing Double Glazed Windows

Double-glazed windows "blow" in the wind, argon that is insulating escapes, causing the window to lose energy efficiency. The good news is that blown double glazing can often be repaired without the need to replace your windows completely.

The most typical sign of a damaged window seal is condensation or water between double-glazed windows. A professional can fix this issue, thereby preventing you from needing to replace the window.

Remove the Sash

Double-glazed windows are a fantastic option to add style and value to your home. They increase the energy efficiency of your home by keeping cold and heat out. With Minnesota's harsh winters double-glazed windows can help reduce your heating bills.

The main difference between single and double glazed windows is that the gap between panes of glass is filled with either air or an inert gas, like argon. This makes a huge difference to the insulating 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 can increase their insulation properties.

Double-glazed windows are also more secure than single-paned windows. They are much more 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 even more secure. Double-glazed windows are more sturdy and less prone than single-glazed windows to shake or vibrate in the winds. They are a great option for older homes.


Double-glazed windows can also be made of low-energy glass, which blocks UV rays entering your home. This will protect your carpets, furniture and paintings from discoloration. This is especially useful for windows that are in direct sun for most of the time of the day.

Retrofitting a sash window that is old with double glazing is also cheaper than buying new windows. The cladding and internal linings of your existing windows are in good condition which makes the task less invasive.

Double-glazed windows are more efficient than taking a window off and replacing it. This means you can benefit from energy efficiency, enhanced security, and less glare as well as UV damage to your furnishings at a lower cost.

Take the Glass off

As opposed to single pane windows double-glazed windows have two glass panes that are separated by a spacer and a layer of air which provides insulation. The IGU, also known as an insulated glass unit (IGU) can be filled with gases such as Krypton or argon for more insulation. These units can become damaged as time passes and stop functioning correctly. If this happens it is crucial to take away the broken glass as quickly and safely as is possible.

It isn't easy to replace double-glazed windows on your own. You'll need specialist tools and experience. This is why it's usually best left to a professional who can make use of the right safety equipment and follow the proper procedure to prevent injuries.

Make sure the area around the window frame is free of any debris and clean. You should also place a thick piece of plastic over the area where the deglazing tool will score to take any broken pieces of glass and make them easier to remove.

It's important to check for signs of double-glazed windows that aren't functioning correctly. A window that is draughty is one of the most obvious signs that your IGU is blowing and no longer provides 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 reduce energy costs but also protects furniture from heat and light. Furniture may deteriorate or break if it is exposed to intense sunlight for a long time. Double-glazed windows keep your furniture from the sun and reduces the amount of heat that enters your home.

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

Remove the Gaskets

Double glazing is a popular choice to increase the efficiency of your home's energy use however, like all other things, it can be prone to wear and wear and tear. Damages that are visible, draughts, and condensation are all indications that it's time for you to repair or replace your double glazed windows.

The most important component of the window assembly is the gasket, a butyl or neoprene rubber seal that cushions the glass and provides weather protection. Deterioration of the gaskets is a common reason for leaks as well as moisture infiltration into buildings. Fortunately, the seals can be replaced without replacing the entire window.

Gaskets can be repaired by making them tight and then pulling them out. It is much easier to repair uPVC frames rather than timber or aluminum. If you're unable to remove seals manually, you can use a builder’s knife to pry the seals apart until you can grasp it with your fingertips. After the seal is removed, you can use an alternative seal for a tighter fit and maximum efficiency.

After the seals have been replaced, the window beading must be removed. This can be done with either a putty knife, or a lead knife. Insert 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 frame from the bead.

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

After the frame has been cleaned, it's recommended to spray it with window cleaner prior to installing the DGP. This prevents the tape from instantly sticking to the glass, allowing you the chance to put it in the right way. It's also a good idea to wipe the seals with a soft cloth and warm soapy water to prevent any damage.

Seal the window

If you notice that your double glazed windows are becoming cloudy or you notice that there is condensation between the panes, then it may be the time to seal them. This is a clear indication that the seal inside has failed to keep the insulation gases in. It is not uncommon for the seal made of rubber that holds in the gases that are insulating to wear out in time or because of an improper installation.

A skilled window specialist will reseal every gap by applying a fresh seal. The technician will use silicone caulk to seal the gaps. This will keep the cold winter air out while allowing the warm indoor air inside. This caulk can stop insects from getting into your home and will also stop moisture from getting in.

Re-sealing double-glazed windows not an easy DIY task. However it is possible. It is a lengthy and laborious task that requires special tools to take off the old seal, clean up the area and then put in new caulk. To prevent injury and to ensure the work is done properly it is recommended to enlist the help of a professional perform the task.

In certain situations double-glazed windows cannot be repaired and will need to be completely replaced.

It is recommended to speak with a double glazing expert to find out what the best solution is in these instances.

The misting that occurs on the 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 and it might inject an argon gas to provide additional insulation. If these treatments fail, moisture can be allowed to get into the gaps between the glass panes and it could cause condensation. This problem can be fixed by a professional who drills tiny holes in the glass panes, and then pipeing into a dehydrating solution to eliminate the moisture. They will then fill the gap with a fresh insulating gas and seal the gap, but without letting the gas escape.
