Why Repairing Double Glazed Windows Is The Next Big Obsession
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, blowing double glazing is usually repairable without having to replace the windows.

The most frequent sign of a damaged window seal is condensation or moisture between double-glazed windows. This can be repaired by a professional saving you the expense of a replacement window.

Remove the Sash

Double-glazed windows are a fantastic way to add style and value to your home. window repairs increase the energy efficiency of your home by keeping cold and heat out. Double glazed windows can help you reduce your heating costs in Minnesota's harsh winters.

The primary distinction between double and single glazed windows is the gas that fills the space between panes of argon or air. This can make a significant difference to your windows' insulation capabilities by preventing heat from passing through the glass. Selecting an inert gas with low thermal conductivity, such as argon or krypton which can help increase your window's insulating properties even more.

Double-glazed windows are also more secure than windows with a single pane. They are less resistant to breaking and can be fitted with modern security locking systems. They can be equipped with laminated or toughened glass to make them safer. Double-glazed windows are more robust and less likely to rattle in the wind or due to the impact of traffic which makes them a great option for older homes.

Double-glazed windows can also be constructed of low-energy glass which blocks UV rays entering your home. This will help protect your furnishings, carpets and paintings from becoming faded. This is particularly helpful when your windows are in direct sunlight for the majority of the day.

Retrofitting old sash window with double glazing is more affordable than buying new windows. The cladding, internal linings and opening mechanisms of your current windows are still in place, which means the job is much less invasive.

Installing double-glazed windows is faster than taking a window off and replacing it. This means that you will be able to enjoy the benefits of energy efficiency, increased security and reduced glare and UV damage to your furnishings for an even better price.

Remove the Glass

As opposed to single pane windows double glazed windows have two glass panes separated by a spacer and a layer of air that acts as insulation. This insulation unit (IGU) that is filled with gases such as Krypton or argon, can offer even more insulation. These units are susceptible to being damaged over time and cease to function correctly. If this happens it's crucial to get rid of the damaged glass as quickly and safely as you can.

Replacing double glazed windows can be a challenging DIY task that requires specialist tools and skills. This is why it is typically best left to a professional who can utilize the appropriate safety equipment and follow the correct procedure to avoid injuries.

It is important to do this since double-glazed windows are very fragile and easily crack or break. Wear a respirator, gloves and mask to protect yourself while repairing the window. It is also important to ensure that the the frame is free of debris. Then, you need to put a thick piece of plastic over the frame which will be cut by the deglazing tool in order to catch the fragments of glass that are broken and make it easier to remove them.

It's important to check for indications that double-glazed windows aren't working correctly. Draughty windows are one of the primary indicators that your IGU is blown and doesn't provide adequate insulation. It is also possible to 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 protects furniture from heat and light. Furniture can break and fade if exposed to sunlight for prolonged periods of time, however a double-glazed window will keep your furniture out of direct sunlight and reduce the amount of heat that is brought into your home.


Apart from being a great option to reduce electric bills, effective double glazing can also increase the value of your home. If you're planning to sell your home in the near future installing double glazing is a smart investment that can draw potential buyers.

Remove the Gaskets

Double glazing is an excellent method of increasing the energy efficiency of your home, but it is susceptible to wear and tear over time. Double glazed windows that show visible damage, have draughts or are susceptible to condensation need to be repaired or replaced.

The most important component of the window assembly is the gasket, a neoprene or butyl rubber seal that cushions the glass and provides protection from weather. Gaskets that are damaged are the main reason for leaks and the infiltration of moisture into buildings. Fortunately, these seals can be replaced without having to replace the entire window.

Gaskets can often be repaired by making them tight and pulling them out. It is easier to repair uPVC frames rather than timber or aluminum. If you are unable remove seals by hand, you can use a knife for construction to break the seals apart until it is possible to grasp it using your fingertips. After the seal has been removed, you can use a new seal for a tighter fit and maximum efficiency.

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

After you have removed the beading you can take off the glass. The gap between the two panes must be about 12mm and it is important to fill it with Argon gas for optimum thermal performance. It is possible to increase the distance between your panes in order to reduce noise, however this will decrease the insulating properties of your windows.

It's a good idea spray the window cleaner onto the frame after it's been cleaned. This will help the DGP stick better. This will prevent the tape from securing to the glass, giving you a chance to position it correctly. It is also recommended to clean the seals with a soft cloth and warm soapy water in order to avoid any damage.

Reseal the Window

It is possible to seal your double-glazed windows if you notice that they are fogged up or have moisture between them. These types of problems are a clear sign that the seal inside isn't able to hold the gas that is used to insulate. It is not uncommon to find the rubber seal that holds in the insulating gases to degrade as time passes or due to inadequate installation.

A window specialist who is experienced will reseal the glass unit by applying an entirely new seal around each of the gaps that are insulating. The technician will use a silicone caulk to close the gaps. This will keep winter cold air out and the warm air inside. This caulk will stop insects from getting into your home and also prevent moisture from entering.

It is important to remember that resealing a double glazed window is not a DIY job however it is possible to do it yourself. This is a lengthy and laborious job that requires special tools to get rid of the old seal, then clean the area and put in a fresh caulk. It is a good idea to call in a professional glazier to do the work to avoid injuries and to ensure it is done properly.

There are instances in which double-glazed windows cannot be repaired and must be replaced. This can be caused by cracked or shattered glass, extensive damage to the frame or serious decay. Talk to a double-glazing professional to determine the best solution in these situations.

The misting of windows is often an indication of a poor treatment of the glass at the factory. The factory will put a low-emissivity layer on the window to reflect heat. They may also pump in argon for extra insulation. When these treatments fail, moisture is allowed into the gap between the glass panes, and it could cause condensation. A professional can fix this issue by drilling tiny holes in the glass panes, and then pipe in an agent that dehydrates to eliminate the moisture. They then fill the gap with a new gas for insulation and reseal the hole without letting the gas escape.
