Double Glazed Window Repairs
Double glazing can be an excellent investment, but it can also be it can be frustrating when it doesn't perform. Most issues can be addressed and you don't have to replace windows or doors.
Double-glazed windows are made up of two glass panels that are separated by an extremely thin gap, filled with insulating gas, such as Krypton or argon. This helps increase the efficiency of a window's heating.
Broken panes
Double-paned windows are harder to break than single panes of glass but they can still shatter or crack. When a pane becomes broken in your double-glazed windows, it's essential to repair it immediately to avoid water and energy loss.
Depending on the extent of the crack you may decide to use an interim fix or go for an intensive repair using epoxy. A temporary repair can keep cracks from spreading and keep out rain and cold air. A more extensive repair will strengthen the crack and create an even stronger seal.
To replace a broken double-pane window, remove the frame and place it on an un-slip surface. Apply a duct tap grid over the pane in order to stop glass fragments from falling during removal. Once the tape has been applied, remove the double-pane glass that was previously in the frame. Then, clean the grooves and rabbet using a wire brush, vacuum or wipe with a damp cloth. Remove the wood moldings if necessary and scrape off any metal glazing points or putty prior to putting in the new pane. Finally, apply a silicone caulk to the rabbet and grooves in order to ensure an ideal fit.
If you're looking to fix the cracks in your window yourself, start by sanding the rabbet until it's smooth and free of gunk or paint. Heating guns can be used to soften any glazing or putty points. After the rabbet is cleaned, you can use a putty blade to push the rope into position. Make sure that the putty has an even thickness, and that it presses equally against the glass and frame.
If you're looking for a long-term solution, you can opt for an epoxy repair instead of replacing. This is more expensive and will require a longer wait time, but can be more attractive. It will also last longer than an immediate fix.
Condensation
Condensation is one of the most common double glazed window issues, but it doesn't mean that your windows aren't working properly. The fact that your windows show condensation is actually a positive indication that your double glazing is performing what it is supposed to do, keeping cold out and letting warmth in.
When you see condensation forming on the outside of your window it is actually water vapor coming from the inside of your home that has been cooled and condensed onto the glass's surface. It's a natural phenomenon that won't cause harm to your windows, except if you let it sit on the surface long enough.
Internal condensation is often caused by high humidity in the room or low internal temperatures, causing cold surfaces such as windows to draw moisture from air that has a high dew point (the temperature at which water changes into liquid). It is also commonplace in kitchens and bathrooms due to the steam that comes from kettles, showers, and hot pots and pans that are used for cooking.
To avoid condensation, try not to hang wet clothing near your windows and always ensure that your uPVC frames have plenty of air circulation to avoid the accumulation of moisture. Also, ensure that your double-glazed windows are properly insulated and fitted, with the proper gap (6mm is the ideal) to ensure maximum energy efficiency. You can also add one-way air vents to your windows to increase the insulation. If you're still experiencing condensation, there's probably an issue with the gaskets or seals and this is definitely an issue that requires the expertise of an expert.
Draughts
A window that isn't properly sealed can be an indication that the seal between your glass panes has failed and will require to be replaced. This can affect the insulation in your home and also increase energy bills.
A window repair service will replace the sealed unit for you, restoring the effectiveness of your windows. They can also upgrade your frames to incorporate new energy-saving features, such as gas filled argon glass units that have thermal spacer bars. https://www.repairmywindowsanddoors.co.uk/bow-windowrepair/ will reduce heat loss and lower your heating bills.
It's also worth checking the locking mechanisms of your double-glazed windows. It's normal for older uPVC window lock mechanisms to become stiff with age. This can be easily corrected by regularly lubricating the locks using a specialist uPVC cleaner.
A professional double glazing business can ensure that your repair is done properly. They'll have the tools needed to ensure that your window is watertight and fully resealed. They'll also be able to repair any other damages to your frame so you can enjoy your stunning new double-glazed window with confidence.

Contact your local double-glazing repair services immediately if you discover any of these problems. You'll be glad you did. A properly repaired double glazing installation will give your house that tangible sense of quality, and will also help you save money on your energy bills!
Smudging
Double-glazed windows are comprised of two separate panes with a spacer or dense gas between. This creates a solid seal to stop heat from getting out of the frame. They are a great method to conserve energy and reduce your carbon footprint. However, double glazing can experience a variety of issues that can affect its performance and endurance. This includes condensation, fog and being difficult to close or open.
If you're having trouble opening your double-glazed windows it could be due to the weather. It could also be a problem with the hinges or handles. You can solve the issue by wiping down and lubricating the windows with cold water. Contact the company who supplied you with windows as soon as you can to have them fixed.
This is another issue that can be fixed easily. Again, it's worth checking the warranty to see what repairs are covered under this.
Foggy or fogged glass is caused by the presence of moisture between the panes. It's typically a sign that the seals aren't working properly or that the double-glazing system needs to be replaced. It's a fairly simple fix and often you can do it without having to replace the entire window, which will save you money.
To fix this problem technicians will make small holes to let out any moisture that is trapped between the glass and the rest the window. After the moisture has gone the new anti-fog coating will be applied and the window sealed. Occasionally, the window may require removal prior to this happens but the majority of the time, it can be done from the inside of the home.
Mist
Double glazing that is older can have a mist issue in particular when it occurs both in and out of the window. This is due to a failure of the seal designed to block moisture and air between the two panes. In the production of double-glazed units the seal is made by sealing both panes with an airtight polysulphide or butyl seal around the edges of the glass and the spacer bar. This is designed to provide insulation and keep the window from being leaking. It isn't easy to clean double-glazed windows that have mist, as you need to break the seal to clean them.
The problem with mists is that they allow moisture to enter and cause condensation between the glass panes. This is due to a large difference in temperature between the external and internal surfaces of the glass. The moisture gets trapped in the gaps, giving the appearance of milky. This can be very unattractive and is difficult to remove.

Some companies claim that they can repair misting double-glazed windows by drilling holes in the unit and injecting chemicals through the holes that absorb moisture from the inside. But, this isn't an end-to-end solution to the problem and it is far easier to replace the whole double-glazed unit if you are experiencing misting.
The best way to avoid misty double glazing is by maintaining a high level of ventilation and cleaning your windows regularly. Utilize extractor fans to lessen moisture buildup in bathrooms and kitchens. Wipe down windows with a damp cloth to avoid this. If you are unable to avoid the problem, we recommend that you replace windows that are double-glazed with A-rated windows to increase the efficiency of your energy bills.
