Double Glazed Window Repairs
Double glazing can be an excellent investment, but it can also be frustrating when it fails to work. Most issues can be fixed and you don't need to replace windows or doors.
Double glazed windows consist of two glass panels that are separated by a thin gap, which is filled with an insulating gas such as Krypton or argon. This improves the efficiency of windows.
Broken panes
Double-pane windows are resistant to breaking than single-pane glass, they can still break or shatter. If a pane breaks in your double glazing, it's crucial to fix it as soon as possible to avoid moisture and energy losses.
You can select either a temporary repair or more intense epoxy fix based on the severity of your crack. A temporary repair can help to prevent further cracking, and will keep out rain and cold air. A more extensive repair may reinforce the crack and create more secure seal.
To replace a broken double-pane window, first remove the frame from the sash and place it on the table. Apply a grid of duct tap over the pane in order to prevent any glass fragments from falling during removal. After the tape has been installed, remove the double-pane glass that was previously in the frame. Next clean the rabbet and grooves using a wire brush and vacuum or wipe them 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 silicone caulk into the rabbets and grooves to ensure a snug fit.
If you want to repair damaged windows yourself, start by sanding the rabbet until it's smooth and clear of gunk or paint. You can also use a heat gun to soften any putty or glazing points. Once the rabbet has been cleaned and sanitized, a putty knife may be employed to press a rope of putty into position. Make sure that the putty is of a uniform thickness, and that it presses evenly against the glass and frame.
If you're looking for a long-term solution you can choose an epoxy repair instead of replacing. This option requires more work and a longer wait time however it is more appealing and will last much longer than a temporary repair.
Condensation
Condensation can be a common issue for double-glazed windows however, it doesn't mean that they're defective. The fact that your windows show condensation is actually a positive indicator that your double glazing is doing what it's supposed to do, keeping cold out and letting the warmth in.
When you notice condensation developing on the outside of your window it is actually water vapor from inside of your home that has cooled down and condensed onto the surface of the glass. It's a natural phenomenon that isn't harmful to your windows except if you let it sit on the surface long enough.
Internal condensation is usually caused by excessive humidity in the room or low internal temperatures, causing cold surfaces such as windows to draw moisture from air that has high dew points (the temperature at which water turns back into a liquid). The steam from showers, kettles and hot pots and the cooking pans can also cause a lot of humidity around bathrooms and kitchens.
To avoid condensation, make sure not to hang wet clothes near your windows and always make sure that your uPVC frames have plenty of air circulation to prevent the accumulation of moisture. It is also important to make sure that your double-glazed windows are properly insulated and fitted, with the proper gap (6mm is the ideal) for optimum energy efficiency. It is also possible to add one-way air vents to your windows to improve insulation. If you're still getting condensation, there's likely a problem with the seals or gaskets and this is something that should be handled by an expert.
Draughts
A window that isn't draughty is a sign that the seal between the glass panes of your double-glazing has sprung a leak and is likely to require replacement. upvc repairs could affect the insulation of your home and increase the cost of energy.
Window repair services can replace your sealed unit, restoring efficiency to your windows. They can also upgrade your existing frames to include new energy efficient features, such as gas-filled argon glass units that have thermal spacer bars that will reduce the loss of heat and reduce the cost of heating.
Draughts can also be caused by issues with the locking mechanisms of your double glazed windows It's a good idea to have the windows checked. Older uPVC window locks are notorious for becoming stiff with time, but it's easy to fix this issue by lubricating them regularly with an expert uPVC cleaning product.
Having a professional double glazing company carry out the repair will ensure that the repair is done correctly. They'll have the appropriate tools to make sure that your window is resealed and watertight. They'll also be able to repair any other damage to your frame so you can enjoy your stunning new double glazing with confidence.
Double-glazed windows are durable and durable, but they can sometimes develop problems as a result of wear and tear or the weather. Call your local double-glazing repair service whenever you discover any of these issues. You'll be thankful that you did. A well-maintained double glazing installation will give your house the tangible impression of quality and will also save you money on your energy bills!
Smudging
Double-glazed windows consist of two panes that have an air spacer or dense gas between them to create an effective seal that blocks heat from passing through the frame. They are a great method to save energy and decrease the carbon footprint of your home. However, double glazing can encounter a myriad of issues that can affect its performance and longevity. These include fog, condensation and being difficult to close or open.
Inability to open your double-glazed windows could be caused by the weather or it might be a fault with the hinges or handles or mechanism. Cleaning them with cold water and then lubricating them may help alleviate the issue, but you must contact the company you bought windows from as soon as you can to get it fixed.
If your doors or windows have sagged or dropped over time, this is another frequent issue that can be easily fixed by a trained professional. It is also worth checking the warranty to see what, if any, repairs are covered under this.
Fogged or foggy glass could be caused by moisture in the panes and is usually the result of seals that are not working or a double-glazing unit that requires replacement. It's a relatively straightforward fix and often you can do it without having to replace the entire window, which will save you money.
To fix this issue, a technician will make tiny holes to let out any moisture that is trapped between the glass panes and other parts of the window. When the moisture is gone then a new anti-fog coating will be applied and the window sealed. Occasionally, the window may need to be removed before this happens however most of the time it can be done from the inside of the home.
Mist
Mist can be a major issue for older double glazing, particularly when it is present on the exterior and the interior of the windows. It is caused by an issue with the seal designed to keep air and moisture out between the two panes. This seal is constructed during the production of double-glazed units by sealing both panes with an airtight polysulphide or butyl seal around the edges and a spacer bar. This is intended to provide insulation and keep the window from leaking. If you have misted double glazed windows, it may be a challenge to remove and clean, as you will need to break through the hardened seal to clean.
The problem with mists is that they permit moisture to penetrate and cause condensation between the glass panes. The reason for this is that there is a huge difference in temperature between the internal and exterior glass's surfaces. The water is then absorbed in the gaps and causes a milky white appearance. This can be quite ugly and is difficult to get rid of.
Some companies claim they can repair misting double-glazed windows through drilling holes in the unit and injecting chemical through the holes that absorbs moisture from the inside. But, this isn't a permanent solution to the issue and it is much more efficient to replace the entire double-glazed unit if experiencing misting.
The best way to prevent misty double glazing is by making sure you have adequate ventilation and regularly cleaning your windows. It's also an excellent idea to install extractor fans in bathrooms and kitchens and wipe windows with an damp cloth to minimize the build-up of moisture. If you're unable to completely avoid the issue we suggest replacing your double-glazed units with new A-rated ones to improve energy efficiency.
