Double Glazed Window Repairs
Double glazing is an excellent investment for your home, however it can be frustrating when it fails to function correctly. Most issues can be addressed and you do not have to replace your windows or doors.
Double glazed windows consist of two glass panels separated by an extremely thin gap, which is filled with insulating gas, such as argon or krypton. This increases a window's efficiency.
Broken panes
Double-pane windows are resistant to breaking than single-pane glass, they can still crack or shatter. When a pane becomes broken in your double glazing, it's important to repair it immediately to prevent moisture and energy losses.
Depending on the severity of the crack, you can choose to use an interim repair or more extensive epoxy repair. A temporary repair will help to keep cracks from spreading and keep out rain and cold air. A more extensive repair will strengthen the crack, and create the seal with a stronger one.
To replace a double-pane broken window, take the frame off and place it on an un-slip surface. Apply a grid of duct tap over the pane to prevent any glass fragments from falling off during removal. Once the tape is in place remove the double pane glass out of the frame. Then clean the rabbet and grooves using a wire brush, vacuum or wipe with a damp cloth. If needed, remove the wood molding and scrape away all putty or metal points prior to installing the replacement pane. Apply silicone caulk in the rabbets and grooves in order to ensure a secure fit.
If you're looking to fix a cracked window yourself, begin by sanding the rabbet until it's smooth and free of paint or gunk. You could also use a heat gun to soften any glazing points. Once the rabbet has been cleaned and dried, you can use a putty blade to press the rope into position. Make sure the putty is uniform in thickness and presses against the glass and the frame evenly.
If you want an option that lasts for a long time, you can opt for an epoxy repair instead of replacing. This is more expensive and has a longer waiting period, but can be more appealing. It also lasts longer than an immediate repair.
Condensation

Condensation is one of the most frequent double-glazed window problems, but it doesn't necessarily mean that your windows are defective. The fact that your windows show condensation is a good sign because it means that your double glazing is doing what it's supposed to do, keeping the cold out and letting warmth in.
When you notice condensation developing on the outside of your windows, it is actually water vapor coming from the inside of your home that has cooled down and condensed onto the surface of the glass. It's quite a natural phenomenon and it's not likely to cause damage to your windows unless you let it remain on the glass for too long.
Internal condensation is usually caused by high humidity in the room or low internal temperatures, which causes cold surfaces, like windows, to draw moisture from air that has high dew points (the temperature at which water changes into a liquid). The humidity is also a common occurrence in kitchens and bathrooms because of steam from kettles or showers and hot pans and pots that are used for cooking.
To prevent condensation, try not to hang wet clothes close to windows. Also, ensure that your uPVC frames have ample air circulation to prevent the build-up of moisture. To maximize energy efficiency, you must also make sure that double-glazed windows are properly installed and insulated with the proper gap (6mm). You can also add air vents that are one-way on your windows to increase insulation. If you're still seeing condensation, there's an issue with your gaskets or seals. This is a job best left to a professional.
Draughts
A double-glazed window that is draughty is an indication that the seal between the glass panes is broken and needs to be replaced. This can affect the insulation of your home, and can increase energy bills.
A window repair service will replace the sealed unit for you, while restoring the efficiency of your windows. They can also upgrade existing frames with energy-saving features, like glass units that are filled with argon, as well as thermal spacer bars that reduce heat loss and cut down on heating costs.
It is also worth checking the locking mechanisms of your double-glazed windows. It's normal for older uPVC window lock mechanisms to stiffen with the passage of time. This can be easily fixed by regularly lubricating the locks with a specialist uPVC cleaner.
A professional double glazing business will ensure that the repair is completed correctly. They will have all the tools required to ensure that your window is watertight and fully sealed. They can also fix any damage to the frame so that you can enjoy your new double-glazed window.
Double-glazed windows last a long time and durable, but they may develop issues due to wear and tear or the weather. Contact your local double-glazing repair service as soon as you spot any of these issues. You'll be glad that you did. A well-maintained double glazing installation will give your house that tangible feeling of quality, and will also help you save money on your energy bills!
Smudging
Double-glazed windows consist of two separate panes, with a spacer or dense gas between. This creates a strong seal to stop heat from escaping through the frame. https://www.repairmywindowsanddoors.co.uk/bishopsstortford-windowrepair/ are a great method to conserve energy and reduce your carbon footprint. Double glazing can be plagued by several issues that could affect its performance and longevity. These include condensation, fog and difficulties to close or open.
The difficulty in opening your double-glazed windows could be due to the weather, or it could be due to a problem with the hinges, handles or mechanism. It is possible to solve the issue by wiping down and lubricating the windows with cold water. Contact the company that sold you windows as soon as you can get them fixed.
If your doors or windows have become sagging or dropped over time, this is another frequent issue which can be easily solved by a trained professional. Also, make sure to check the warranty to see what, if any, repairs are covered under this.
Fogged or foggy glass is caused by the presence of moisture between the panes. It's typically a sign that the seals aren't functioning properly or your double-glazing unit requires to be replaced. This is a simple fix that can be accomplished without having to replace the entire window.
To fix this problem the technician will make small holes to let out any moisture between the glass and the rest the window. Once the moisture has been removed, a new antifog coating is put on and the window is sealed. Sometimes, windows need to be removed however, in the majority of instances, it can be done at home.
Mist
Mist can be a huge problem with older double glazing, specifically when it occurs on both the inside and outside of the windows. This is caused by an issue with the seal that is designed to hold air and moisture between the two panes. The seal is made during the production of double-glazed units by sealing the two panes using an airtight polysulphide or butyl seal around the edges and spacer bar. This seal is designed to stop the window from leaking and to provide insulation. It can be difficult to clean misted double-glazed windows, as you need to break the seal to do this.
The problem with mist is that it lets moisture in which eventually causes condensation between the glass panes. This is due to a large difference in temperature between the internal and external surfaces of the glass. The moisture is then trapped within the spaces and gives the appearance of a milky white. This can be extremely unsightly, and can be difficult to remove.
There are a number of companies who claim they can fix your double-glazed windows that are misting by drilling holes into the unit and injecting chemicals through the holes which then absorbs the moisture within. This is not a permanent fix and it's more cost-effective to replace the entire double-glazed unit.
The most effective way to avoid misty double glazing is by keeping a good level of ventilation and cleaning your windows regularly. It's also recommended to use extractor fans in kitchens and bathrooms and wipe windows with a damp cloth to reduce the build-up of moisture. If you are unable to completely avoid the issue, we recommend replacing the double-glazed units you have with A-rated units to increase the efficiency of your energy usage.
