Double Glazed Window Repairs
Double glazing can be a fantastic investment for your home, however it can be a hassle if it doesn't work properly. Luckily, the majority of issues can be fixed and you don't need to replace your windows or doors.
Double glazed windows consist of two glass panels separated by a very thin gap, filled with insulating gas such as argon or krypton. This makes windows more efficient.
Broken panes
Double-pane windows are resistant to breaking than single-pane glass, they can still crack or shatter. It's important to fix any broken panes in double glazing as soon as you can to prevent the loss of energy and moisture.
Depending on the degree of the crack, you may decide to use an immediate repair or a more intensive epoxy repair. A temporary repair can help prevent further cracks, and keep out rain and cold air. A more extensive repair will strengthen the crack, and will provide a stronger seal.
To replace a broken double-pane windows, first remove the frame from the sash and set it on the table. Install a grid of duct tap over the pane in order to prevent any glass fragments from falling off during removal. After the tape has been removed, take the old double-pane glass out of the frame. Next clean the grooves and rabbet using a wire brush and vacuum or wipe with a damp cloth. If needed, take off the wood molding and scrape away all putty or metal points before installing the replacement pane. Apply a silicone caulk to the rabbet and grooves to ensure that the fit is secure.
If you want to repair damaged windows yourself, begin by sanding the rabbet until it's smooth and free of paint or gunk. You can also use a heating gun to soften any glazing points. After the rabbet is cleaned then you can use a putty knife to push the rope into position. Make sure the putty is uniform in thickness and is pressed against the glass and the frame evenly.
If you prefer a long-term fix, an epoxy repair is a better option over a replacement. This is more expensive and requires a longer waiting time, but can be more attractive. It also lasts longer than a temporary fix.
Condensation
Condensation is one of the most common double glazed window issues, but it doesn't mean that your windows are defective. It's good to know that your windows display condensation. This indicates that your double glazing is working as it is supposed to, preventing the cold and keeping in the heat.
It's actually water vapour from your home that condenses on the glass's surface when you see condensation. It's quite a natural phenomenon and it's not likely to cause harm to your windows unless you allow it sit on the glass for too long.
The reason for internal condensation is usually too much humidity or low temperatures in the room. This results in cold surfaces, such as windows and doors, to draw in moisture that is high in dewpoint (the temperature where water turns into liquid). The steam from showers, kettles and hot pots as well as cookers can also cause humidity around kitchens and bathrooms.
To avoid condensation, try not to hang wet clothes near your windows and always ensure that your uPVC frames have ample air circulation to stop the build-up of moisture. Also, ensure that your double-glazed windows are correctly insulated and installed with the right gap (6mm is the ideal) to maximize energy efficiency. You can also try adding air vents that are one-way to your windows to improve insulation. If you're still seeing condensation, there's the issue is with your gaskets or seals. This is a task that should be left to professionals.
Draughts
A window that isn't draughty is a sign that the seal between the glass panes of your double glazing has started to leak, and it's likely to need replacing. upvc window repairs can affect the insulation of your home, and can increase the cost of energy.
Window repair services will replace your sealed unit, restoring energy efficiency to your windows. They can also modify your existing frames to incorporate new energy-saving features, such as argon gas filled glass units that have thermal spacer bars, which will cut down on the loss of heat and reduce your heating bills.
Draughts can also be caused by problems with the locking mechanisms of your double glazed windows and doors, so it's important to have these checked. It is common for older uPVC window lock mechanisms to become stiff as they the passage of time. This can be easily fixed by regularly lubricating the locks using a specialist uPVC cleaner.
A professional double glazing company can ensure that your repair is completed correctly. They will have all the tools required to ensure that your window is watertight and fully resealed. They can also repair any damage to the frame so you can enjoy your new double-glazed window.

If you find any of the issues mentioned above contact your local double glazing repair service immediately to fix them as soon as you can. You'll be glad that you did it. A double glazing installation that's well-maintained will give your house a an impression of quality, and will also save your energy costs!
Smudging
Double-glazed windows consist of two separate panes, with an air spacer or dense gas between. This creates an effective seal to stop heat from getting out of the frame. They're a great option to save energy and reduce your carbon footprint. However, double glazing can encounter a myriad of issues that could impact its performance and durability. These include condensation, fog and difficulty closing or open.
If you're having trouble opening your double-glazed windows, it could be due to the weather. It could also be due to a issue with the hinges or handles. You can ease the problem by lubricating and wiping the windows with cold water. Contact the company that sold you windows as early as you can to fix them.
If your doors or windows have sagged or dropped over time, this is another common problem which can be easily solved by a skilled professional. Also, make sure to check the warranty to determine what, if any, repairs are covered under this.
Fogged and foggy glass can be caused by moisture between the panes and is usually an indication of damaged seals or an old double-glazing unit that requires replacement. It's a relatively straightforward fix and you can often complete the task without the need to replace the entire window, which can reduce the cost of replacement.
To address this issue A technician will make tiny holes to vent any moisture that is trapped between the glass panes and the rest of the window. Once the moisture is removed, a new antifog coating is put on and the window is sealed. Sometimes the window will need to be removed, but in most instances, it can be done at home.
Mist
Double glazing that has been in use for a long time may have a mist problem in particular when it happens both within and outside the window. It is due to an issue with the seal designed to keep moisture and air between the two panes. This seal is created when making double-glazed units by sealing the two panes using an airtight seal made of polysulphide or butyl around the edges and spacer bar. This is designed to create insulation and prevent the window from being leaking. If you have misted double glazed windows, it may be a challenge to remove and clean, since you will need to break the hardened seal to clean.
The problem with mists is that they allow moisture to penetrate, which leads to condensation between the glass panes. The reason is that there is a significant difference in temperature between the internal and exterior glass's surfaces. The moisture is then trapped in the spaces and creates an appearance of milky white. This can be very unsightly and is difficult to remove.
Some firms claim to be able to repair misting double-glazed windows by drilling holes into the unit and injecting chemicals through the holes that absorb moisture from the inside. It's not an end-to-end solution and it's more cost-effective to replace your entire double-glazed unit.
The most effective method to avoid double glazing that is smudgey is by maintaining a high level of ventilation and regularly cleaning your windows. It is also an excellent idea to install extractor fans in bathrooms and kitchens and clean windows with a damp cloth to reduce the build-up of moisture. If you are unable to avoid the issue, we suggest that you replace windows that are double-glazed with A-rated units to improve energy efficiency.
