5 Reasons Repairing Double Glazed Windows Is Actually A Great Thing

Repairing Double Glazed Windows

When double-glazed windows "blow", the gas that insulates them, argon, escapes, causing them to decrease their energy efficiency. The good thing is that double glazing is often repaired without having to replace your windows completely.

Condensation or moisture in between your double-glazed windows is a typical sign that your window seals have failed. A professional can easily repair this, preventing you from having to replace your window.

Remove the Sash

Double-glazed windows can add value and elegance to your home. They can improve the efficiency of your home's energy usage by keeping the cold and heat out. Double-glazed windows can help you reduce your heating costs in Minnesota's harsh winters.

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

Double-glazed windows are also more secure than single-paned windows. They are less secure and resistant to breaking. They can also be fitted with modern security locking systems. They can also be fitted with toughened or laminated glass, which makes them more secure. Double-glazed windows are more sturdy and less likely than single-glazed windows to shake or rattle in the winds. They are a great choice for older homes.

Double-glazed windows can also be constructed of low-energy glass which reduces the UV rays that penetrate your home. This can help protect your furnishings, carpets and paintings from fading. This is particularly important when you have windows that are in direct sunlight for the majority of the day.

The other reason that homeowners opt to have their old sash windows retrofitted with double glazing is that they are cheaper than the installation of new windows. The cladding, internal linings and opening mechanisms of the existing windows remain intact, so the job is much less demanding.

Double-glazed windows are more efficient than removing a window and replacing it. That means that you can benefit from energy efficiency, increased security and reduced glare and UV damage to your furnishings at a lower cost.

Remove the Glass

As opposed to single pane windows double-glazed windows feature two glass panes separated by a spacer, and a layer of air which provides insulation. This insulation unit (IGU), which is filled with gases like Krypton or argon, could offer even more insulation. These units may become damaged as time passes and stop functioning properly. In the event of this it is crucial to take away the damaged glass as quickly and safely as is possible.

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

It is essential to do this because double-glazed windows can be very fragile and are prone to crack or break. Wear a respirator or mask and gloves to protect yourself when repairing the window. It is also important to ensure that the area around the frame is free of debris. Also, window repairs near me should put a thick piece of plastic over the area where the deglazing tool is going to score to catch any broken pieces of glass and make them easier to remove.

It is crucial to identify signs of double-glazed windows that aren't working properly. A draughty window is among of the most frequent signs that your IGU has burst and isn't providing adequate insulation. You can also determine if your windows are cloudy or the presence of condensation between them.

Double glazing isn't just an option to reduce energy costs but also protect your furniture from light and heat. Furniture can deteriorate or break if exposed to intense sunlight for a long duration. Double-glazed windows keep your furniture out of the sun and also reduces the amount of heat that enters your home.

Apart from being a great way to save on electricity costs, efficient double glazing can also boost the value of your home. Installing double glazing is a great investment if you are planning to sell your house in the near future.

Remove the Gaskets

Double glazing is a great method to boost the energy efficiency of your home, but it can wear out over time. Damages that are visible, draughts, and condensation are all indications that it's time to repair or replace your double-glazed windows.

A key part of the window assembly is the gasket, which is a butyl or neoprene seal that cushions the glass and provides protection from weather. Gaskets that are damaged are the main reason for leaks as well as water infiltration into buildings. Fortunately, the seals can be replaced without replacing the whole window.

Gaskets can be repaired by pressing them down and pulling them out. It is simpler to repair uPVC frames than timber or aluminum. If you are unable to remove seals on your own, you can use a knife designed for builders to cut the seals apart until you are able to grasp it with your fingertips. Once the seal has been removed, you can replace it with a brand new seal to ensure a snug fit and maximum effectiveness.

After the seals have been replaced, the window beading must be removed. You can make use of a lead or putty knife to remove the window beading. Place the blade between the frame and the bead in the middle of the longest bead. This will give you the most leverage to cut the bead from the frame.

After you have removed the beading you can then remove the glass. For optimum thermal efficiency, the gap between two panes must be 12 millimeters. Argon gas should be used to fill the gap. It is possible to increase the gap between your panes in order to lower noise, but this will decrease the insulating properties of your windows.

It's a good idea to spray the window cleaner onto the frame after it's been cleaned. This will allow the DGP adhere better. This will prevent the tape from adhering to the glass immediately and give you time to ensure it's placed correctly. To avoid damage, it's worth wiping the seals with a soft rag and warm soapy water.

Seal the window

It could be time to replace the seal on your double-glazed windows if you find that they are smudged up or have moisture between them. These kinds of issues are a clear sign that the inner seal isn't keeping the gas insulating. It is not unusual to find the rubber seal that keeps in the insulating gases to break down over time or due to improper installation.


A professional window specialist will reseal the glass unit by putting an entirely new seal around each of the gaps of insulation. The technician will then fill in the gaps with silicone caulk. This will keep the winter cold air out and the warm indoor air inside. This caulk will prevent insects from getting into your home and also prevent moisture from getting in.

Re-sealing double-glazed windows is not a DIY-friendly task. But it is doable. It is a difficult and time-consuming task that requires special tools to remove the caulk that was used, clean the area, and then apply a new caulk. It is a good idea to get a professional glazier to do the work to avoid injuries and to ensure it is done correctly.

There are some cases in which a double-glazed window will not be repairable and it will need to be replaced. This could be due to broken or cracked glass, severe damage to the frame, or serious rot. Ask a double-glazing specialist to determine the best solution in these situations.

Oftentimes, the misting of the windows is a sign that the treatment of the glass in the factory has failed. The factory will put a low-emissivity coating on the window to reflect heat. It may also pump in the argon to provide additional insulation. If these treatments fail, moisture could enter the gap between the glass panes and cause condensation. A professional can solve this issue by drilling tiny holes into the glass panes, and then injecting a dehydrating agent to get rid of the moisture. They will then fill the space with a new gas for insulation and seal the gap, but without letting the gas escape.
