Repairing Double Glazed Windows

When double glazed windows "blow" the insulating argon escapes, causing the window to lose its energy efficiency. The good thing is that double glazing can be repaired without the need to replace your windows completely.


The most common indication of a failing window seal is condensation or water between double-glazed windows. A professional can easily fix this, saving you from having to replace your window.

Take off the Sash

Double-glazed windows are an excellent way to improve the appearance and value of your home. They also increase the energy efficiency of your home and keep the cold out and the heat in. Double-glazed windows can help you save money on heating bills in Minnesota's harsh winters.

The main difference between single and double windows is that the space between panes of glass is filled with air or an inert gas such as argon. This can make a significant difference in the insulation properties of your windows because they stop the transfer of heat through the glass. By selecting an inert, low-conductivity gas like 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 less likely to be broken and can be fitted with modern security locking systems. They can also be fitted with laminated or toughened glass, making them more secure. Double-glazed windows are more durable and less likely to rattle in the wind or from the impact of traffic which makes them a great choice for older homes.

In addition, double-glazed windows can be made with low energy glass, which can reduce the UV rays entering your home. This can protect your carpets, paintings, and furnishings from fading. This is especially important for windows that are in direct sun for most of the day.

Another reason why homeowners opt to have their old sash windows retrofitted with double glazing is that they are less expensive than installing new windows. The linings and cladding of your windows are intact and make the work easier to complete.

As an added bonus, the installation of double-glazed windows is much faster than the process of removing and replacing a whole window. This means you get the benefits of energy-efficiency, enhanced security, reduced glare, and UV damage on your furnishings at a lower cost.

Take the Glass off

As opposed to single pane windows double-glazed windows have two glass panes separated by a spacer, and a layer of air that provides insulation. The insulated glass unit (IGU) can be filled with gases such as Krypton or argon to provide more insulation. Over time, these units can become damaged and fail to function correctly. It is important to remove any broken glass as securely and quickly as possible.

It isn't easy to replace double-glazed windows on your own. You'll require specialized tools and experience. This is why it is usually best left to a professional who will utilize the appropriate safety equipment and follow the proper procedure to avoid injuries.

This is particularly important as double-glazed windows are fragile and easy to break or even crack. To safeguard yourself when repairing your window, wear gloves with protection and wear a respirator or mask. Make sure the area around the window frame is free of debris and clean. You should also put a large piece of plastic over the area that the deglazing tool will cut to take any broken pieces of glass and make them easier to remove.

It is crucial to identify indications that double-glazed windows aren't functioning correctly. A window that is draughty is one of the primary indicators that your IGU is blowing and is no longer providing adequate insulation. You can also determine the windows are cloudy, or if there is condensation between them.

Apart from conserving energy costs, having efficient double glazing will also keep your furniture safe from the sun's heat and. Furniture can fade and break if exposed to sunlight for prolonged periods of time, but double-glazed windows will keep your furniture out of direct sunlight and reduce the amount of heat that enters into your home.

Apart from being a great method to cut down on electric bills, effective double glazing can also boost the value of your home. If you're planning to sell your home in the future installing double glazing is a good investment that will attract prospective buyers.

Remove the Gaskets

Double glazing is a fantastic method of increasing the energy efficiency of your home, but it is susceptible to wear and tear over time. Damages that are visible, draughts, and condensation are all indicators that it's time to repair or replace your double glazed windows.

A key part of the window assembly is the gasket, a butyl or neoprene seal that cushions the glazing and provides weather protection. Gasket degrading is the primary reason for leaks and moisture entering buildings. Fortunately, the seals can be replaced without replacing the entire window.

The gaskets are often able to be repaired by pinching them and pulling them off. their explanation is easier to do on uPVC frames than on aluminium or timber. If you're unable to remove the seals manually It's a good idea to use a knife for construction to remove the seal until you're able to hold it with your fingers. After the seal is removed, you can put in the new seal to ensure a tighter fit and maximum efficiency.

After the seals have been replaced the window beading has to be removed. This can be done using either a putty knife, or a lead knife. Place 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 remove the frame from the bead.

After removing the beading you can remove the glass. To ensure optimal thermal performance, the distance between two panes must be 12 millimeters. Argon gas should be used to fill the gap. It is possible to increase the distance between your panes in order to lower noise, but this could affect the insulating properties of your windows.

It's a good idea spray the window cleaner on the frame after it has been cleaned. This will help the DGP adhere better. This will stop the tape from adhering to the glass immediately, giving you time to place it in the right position. It's also a good idea to wipe the seals with a soft cloth and warm soapy water in order to avoid any damage.

Re-seal the window

If you notice that your double glazed windows are getting cloudy or you notice that there is moisture between the panes, it could be the right the time to seal them. This type of problem is a clear sign that the seal inside has failed to keep the insulating gases in. This is not uncommon and the rubber that holds in the insulating gas may break down due to wear and tear or improper installation.

A professional window specialist will reseal the glass unit by applying a new seal around each of the gaps of insulation. The technician will fill the gaps with silicone caulk. This will keep winter cold air out and the warm indoor air in. This caulk will stop bugs from entering your home and will also stop moisture from entering.

It is important to remember that resealing an existing double-glazed window is not a DIY task however it is possible to do it yourself. This is a lengthy and laborious job that requires special tools to remove the old seal, clean the area, and then apply new caulk. To avoid injury and ensure the work is done correctly it is best to employ a professional complete the job.

In some instances double-glazed windows cannot be repaired and must be replaced completely. This could be due to cracked or shattered glasses, extensive damage on the frame or serious decay. It is a good idea to speak with an expert in double glazing to determine what the best solution is in these circumstances.

The misting of windows is often a sign of a failed treatment of the glass at the factory. The factory will put a low-emissivity coating to the window to reflect heat and may also inject the argon to provide additional insulation. If these treatments fail, moisture can get into the space between the glass panes and cause condensation. A professional can solve this problem by drilling tiny holes into the glass panes and injecting an agent that dehydrates to eliminate the moisture. The expert will then fill the gap with a brand new insulating gas and seal it, without the gas from escaping.
