Double Glazed Window Repairs
Double glazing can be an excellent investment, but it can also be frustrating when it doesn't perform. Most issues can be fixed and you do not have to replace doors or windows.
Double-glazed windows are made up of two glass panels that are separated by a thin gap, filled with an insulating gas such as argon or krypton. This increases a window's efficiency.
Broken panes
Double-paned windows are less likely to break than single panes of glass, however they are still susceptible to shattering or break. If a pane breaks in your double-glazed windows, it's essential to repair it immediately to avoid moisture and energy losses.
You can opt for an immediate repair or a more extensive epoxy fix based on the severity of your crack. A temporary repair can help prevent further cracking and can protect against the cold and rain. A more extensive repair may strengthen the crack and provide an improved seal.
To replace a double-pane broken window, remove the frame and place it on an un-slip surface. Apply a grid of duct tape over the pane to stop glass fragments from falling off during removal. After the tape is removed, take the old double-pane glass from the frame. Then, clean the rabbet and grooves with a wire brush and vacuum or wipe with a damp cloth. Remove the wood molding if needed and scrape off any metal glazing points or putty prior to putting in the new pane. Apply silicone caulk in the rabbets and grooves to ensure a tight fit.
If you're repairing a cracked glass by yourself, start by sanding the glass until it's smooth and free of paint. You can also use a heating gun to soften any glazing or putty points. Once the rabbet has been cleaned and dried, you can use a putty knife to press the rope into position. Make sure the putty is an even thickness and press against the glass and frame in a uniform way.
If you're looking for a long-term fix an epoxy repair is a better option than replacing. This requires more work and a longer time to wait but it's more attractive and will last much longer than a short-term repair.
Condensation
Condensation is one of the most frequent double-glazed window problems, but it doesn't mean that your windows aren't working properly. It's good to know that your windows display condensation. This means that your double glazing is working as it should, keeping out the cold and retaining the heat.
It is actually water vapour from your home that condenses on the glass's surface when you observe condensation. It's a normal phenomenon and it's not something that's likely to cause any damage to your windows unless you allow it sit on the glass for too long.

The cause of internal condensation is usually a lack of humidity or low temperatures in the room. This results in cold surfaces, like windows and doors, to draw in moisture that is high dewpoint (the temperature where water turns into liquid). The humidity is also a common occurrence in kitchens and bathrooms due to the steam that comes from kettles, showers, and hot pans and pots that are used for cooking.
To avoid condensation, try not to hang wet clothing close to windows. Also, ensure that your uPVC frames have plenty of air circulation to stop the build-up of moisture. You should also ensure that your double-glazed windows are properly insulated and fitted, with the right gap (6mm is the ideal) to maximize energy efficiency. You could also try adding air vents that are one-way to your windows to further improve insulation. If you're still seeing condensation, it's likely a problem with your gaskets or seals. This is a task best left to an expert.
Draughts
A window that is drafty is a sign that the seal between the glass panes of your double glazing has sprung a leak, and is likely to require replacement. This can affect the insulation in your home and increase energy costs.
Window repair services can replace your sealed unit, restoring the efficiency to your windows.

Smudging
Double-glazed windows consist of two separate panes with the spacer or gas in between. This creates a strong seal to stop heat from getting out of the frame. They are a great method to save energy and decrease your carbon footprint. Double glazing can be plagued by many issues that can affect its performance and lifespan. This includes condensation, fog and difficulty closing or open.
Difficulty opening your double glazed windows could be due to the weather, or it might be a fault with the hinges, handles or mechanism. You can ease the problem by wiping down and lubricating the windows with cold water. Contact the company that supplied you with the windows as soon as you can fix them.
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 a good idea to check your warranty to see whether any repairs are covered.
Fogged or foggy glass is caused by moisture in the panes. It's usually 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 issue, a technician will drill tiny holes to let out any moisture between the glass panes and other parts of the window. After the moisture has gone then a new anti-fog coating will be applied and the window sealed. Sometimes, windows need to be taken off but, in most cases, it can be done within the home.
Mist
Mist can be a huge issue with older double glazing, specifically when it is present on the inside and outside of the windows. It is due to a failure in the seal designed to prevent moisture and air between the two panes. https://www.repairmywindowsanddoors.co.uk/ealing-windowrepair/ is constructed during the production of double-glazed units by sealing both panes with an airtight seal made of polysulphide or butyl around the edges and spacer bar. This is designed to provide insulation and keep the window from leaks. If you have misted double-glazed windows, they can be a challenge to remove and clean, as you'll have to break the hardened seal in order to clean.
The problem with mist is that it lets moisture to get in, which then causes condensation between the panes of glass. This is because there is huge differences in temperature between the internal and external surfaces of the glass. The moisture then gets trapped in the spaces and creates the appearance of a milky white. This can be quite unsightly and can be a pain to get rid of.
Some companies claim they can repair misting double-glazed windows through 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.
It is best to keep your windows clean and well-ventilated regularly. It is also an excellent idea to install extractor fans in bathrooms and kitchens, and wipe down windows with a damp cloth to prevent the build-up of moisture. If you're not able to completely avoid the issue, we recommend replacing your double-glazed units with new A-rated ones to boost the efficiency of your energy usage.
