Double Glazed Window Repair Isn't As Tough As You Think
Double Glazed Window Repairs
Double glazing is a great investment, but frustrating when it fails to work. Luckily, the majority of issues are fixable and you do not have to replace your windows or doors.
Double-glazed windows are made up of two glass panes separated by a very thin gap. The gap is then filled with an insulating gas, such as the gas argon. This improves the efficiency of a window's heating.
Broken panes
Double-pane windows are difficult to break than single pane glass, they are still able to 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.
You can choose an immediate repair or a more extensive epoxy fix based on the degree of the crack. A temporary repair can help to prevent further cracking and also keep out cold air and rain. A more extensive repair will strengthen the crack and create an even stronger seal.
To replace a double-pane broken window, remove the frame and place it on an un-slip surface. Then, apply a grid of duct tape on the pane to stop glass pieces from falling off during removal. Once the tape is in place then pull the old double pane glass from the frame. Then you can use a wirebrush to clean the grooves and rabbets. You can also vacuum them or wipe them with a damp cloth. If needed, take off the wood molding and scrape off all metal or putty before putting in the new pane. Apply silicone caulk in the grooves and rabbets to ensure a snug fit.
If you're looking to fix the cracks in your window yourself, begin by sanding the rabbet until it's smooth and free of paint or gunk. The use of heat guns is to soften any putty or glazing points. After the rabbet has been cleaned and sanitized, a putty knife may be used to press a rope of putty into place. Make sure that the putty is a uniform thickness and is pressed against the glass and frame in a uniform way.
If you're looking for the long-term solution, you can opt for an epoxy repair instead of a replacement. This is more expensive and will require a longer wait time however, it is also more appealing. It also lasts longer than a temporary fix.
Condensation
Condensation is among the most common double glazed window issues, but it doesn't necessarily mean your windows aren't working properly. It's good to know that your windows show condensation. This means that the double glazing is functioning as it should, keeping out the cold and keeping in the warmth.
It is actually water vapour from your home that forms a layer on the surface of your glass when you see condensation. It's a natural process that won't harm your windows, except if you let it sit on the surface too long.
The reason for internal condensation is usually excessive humidity or low temperatures in the room. This creates cold surfaces, like windows which draw in moisture with a high in dewpoint (the temperature at which water transforms into liquid). The steam from kettles, showers, and hot pots and cookers can also cause humidity around kitchens and bathrooms.
To avoid condensation, try not to hang wet clothes close to windows. Also, make sure that your uPVC frames have ample air circulation to avoid the build-up of moisture. Also, ensure that your double glazed windows are correctly insulated and installed with the proper gap (6mm is ideal) for optimum energy efficiency. You could also consider adding one-way air vents to your windows to improve insulation. If you're still experiencing condensation, there's an issue with the gaskets or seals and this is definitely something that should be handled by a professional.
Draughts

Smudging
Double-glazed windows consist of two separate panes, with the spacer or gas in between. This creates a solid seal to prevent heat from escaping through the frame. They are a great way to save energy and reduce the carbon footprint of your home. However, double glazing may encounter a myriad of issues that may affect its performance and longevity. These include condensation, mist and being difficult to open or close.
Difficulty opening your double glazed windows could be due to the weather, or it could be a problem with the hinges, handles or mechanism. Cleaning them with cold water and then lubricating them may help alleviate the issue, but you should contact the manufacturer you bought windows from as soon as possible to have it repaired.
This is a common issue that is easily fixable. It is a good idea to check your warranty to see if there are any repairs covered.
Foggy and fogged glass can be caused by condensation between the panes. It's typically an indication of damaged seals or an old double-glazing unit that requires replacement. It's a relatively straightforward fix and you'll often complete the task without having to replace the entire window, which will save you money.
To address this issue technicians will drill tiny holes to let out any moisture between the glass panes and other parts of the window. Once the moisture is gone the new anti-fog coating is applied and the window will be sealed. Sometimes, windows require removal but, in most instances, it can be done from within the home.
Mist
Mist can be a big issue for older double glazing, specifically when it is present on the inside and outside of the windows. This is due to a failure of the seal designed to keep moisture and air between the two panes. In the production of double-glazed units the seal is made by sealing both panes using an airtight butyl or polysulphide seal around the edges of the glass and a spacer bars. This seal is designed to keep the window from leaking and provide insulation. If you have misted double glazed windows it can be difficult to remove and clean, as you'll need to break the hardened seal to clean.
The problem with mist is that it lets moisture to enter, which ultimately results in condensation between the panes of glass. The reason for this is because there is a huge difference in temperature between the internal and exterior surfaces of the glass. The moisture gets trapped in the spaces, creating an appearance of milky. This can be quite unsightly and can be a pain to eliminate.
Some companies claim they can repair misting double-glazed windows through drilling holes in the unit and injecting a chemical through the holes, which absorbs moisture from the inside. It's not permanent solution and it's easier to replace the entire double-glazed unit.
It is best to keep your windows clean and conditioned regularly. Make use of extractor fans to minimize the amount of moisture that accumulates in kitchens and bathrooms. Wipe down windows with a damp cloth to avoid this. If you're not able to avoid the issue completely we suggest replacing your double-glazed units with new A-rated ones to boost the efficiency of your energy usage.
