Double Glazed Window Repairs
Double glazing can be an investment that is worth it, but can be it can be frustrating when it doesn't perform. Luckily, most problems are repairable and you don't have to replace your doors or windows.
Double-glazed windows are made up of two glass panes separated by a very thin gap. The gap is filled with an insulating gas like the gas argon. 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 crack. It's important to fix any broken panes in double glazing as quickly as you can to prevent the loss of energy and moisture.
You can opt for a temporary repair or a more intensive epoxy fix depending on the degree of the crack. A temporary repair can help prevent further cracking, and also keep out rain and cold air. A more extensive repair will strengthen the crack and create the seal with a stronger one.
To replace a broken double-pane window, first take the frame from the sash, and then set it on the table. Apply a grid of duct tap over the pane in order to prevent any glass fragments from falling off during removal. Once the tape is secured, pull 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 upvc repairs and scrape away all putty or metal points before installing the new pane. Apply silicone caulk into the rabbets and grooves in order to ensure a snug fit.
If you're planning to repair the cracks in your window yourself, begin by sanding the rabbet until it's smooth and clear of paint or gunk. You can also use a heating gun to soften any putty or glazing points. Once the rabbet is cleaned and sanitized, a putty knife may be used to push a rope of putty into place. Make sure that the putty has a uniform thickness, and that it presses evenly against the glass and frame.
If you're looking for the long-term solution, you can opt for an epoxy repair instead of replacing. This option is more expensive and will require a longer wait time however, it is also more attractive. It also lasts longer than a temporary repair.
Condensation
Condensation is among the most frequent double-glazed window issues, however it doesn't necessarily mean that your windows aren't working properly. The fact that your windows show condensation is a good sign because it means that your double glazing is performing what it is supposed to do, keeping the cold out and the warmth in.
It's actually water vapour from your home that condenses on the glass's surface when you notice condensation. It's a natural phenomenon that isn't harmful to your windows unless you leave it on the surface long enough.
The cause of internal condensation is usually excessive humidity or low temperatures in the room. This causes cold surfaces, such as windows and doors, to draw in moisture that is high dewpoint (the temperature where water turns into a liquid). The humidity is also a common occurrence in kitchens and bathrooms due to steam from showers or kettles as well as hot pots and pans used during cooking.
To avoid condensation, try not to hang wet clothing near your windows and always ensure that your uPVC frames are able to provide ample air circulation to avoid the accumulation of moisture. It is also important to ensure that your double-glazed windows are properly insulated and fitted, with the correct gap (6mm is ideal) for optimum energy efficiency. It is also possible to add one-way air vents to your windows to increase insulation. If you're still seeing condensation, it's likely an issue with your gaskets or seals. This is a job best left to an expert.
Draughts
A window that isn't properly sealed can be an indication that the seal between your glass panes is broken and needs to be replaced. This could affect the insulation in your home and also increase energy bills.
Window repair services will replace your sealed unit, restoring the efficiency to your windows. They can also upgrade your existing frames with energy-saving features, such glass units that are filled with argon, as well as thermal spacer bars that will cut down on heat loss, and reduce your heating bills.
Draughts can also be caused by problems with the locking mechanisms of your double glazed windows, so it's worth getting these checked out. Older uPVC window locks are known for becoming stiff after a while however it's easy to fix this by lubricating them regularly with a specialized uPVC cleaning product.

Smudging
Double-glazed windows are made up of two separate panes with an air or spacer dense gas between them to create an effective seal that blocks heating from entering the frame. They're an excellent choice to save energy and reduce the carbon footprint of your home. Double glazing can have many issues that can impact its performance and life span. This includes condensation, mist, and being difficult to open or close.
If you're having trouble opening your double-glazed windows, it could be because of the weather. It could also be a problem with the hinges or handles. 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 to have them fixed.
If your doors or windows have become sagging or dropped over time, this is a common issue which can be easily solved by an experienced professional. It's always worth checking your warranty to see whether there are any repairs covered.
Foggy and fogged glass can be caused by moisture between the panes and is usually the result of seals that are not working or an old double-glazing unit that needs to be replaced. It's a relatively straightforward fix and often you can get it done without having to replace the entire window, which will save you money.
To address this issue, a technician will drill small holes to vent any moisture between the glass and the window. After the moisture has been removed the new antifog coating is applied and the window is sealed. Sometimes the window will require removal however, in the majority of instances, it can be done from within the home.
Mist
Mist can be a major issue for older double glazing, specifically 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 between the two panes. This seal is constructed when making double-glazed units by sealing the two panes using an airtight polysulphide or butyl seal around the edges and spacer bar. This is meant to provide insulation and keep the window from leaks. It can be difficult to clean double-glazed windows that have mist because you have to break the seal to do so.
The issue with mists is that they permit moisture to get in which causes 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 then gets trapped in the spaces and creates an appearance of milky white. This can be quite unsightly and is a pain to get rid of.
There are several companies that claim to be able to repair your double glazed windows that are misting by drilling holes into the unit and injecting chemicals into the holes which then absorbs the moisture inside. But, this isn't an effective solution and it's much easier to replace the entire double-glazed unit if suffering from misting.
It is best to keep your windows clean and ventilated regularly. It's also a good idea to use extractor fans in kitchens and bathrooms and wipe windows with a damp cloth to prevent the accumulation of moisture. If you're unable to prevent the problem, we recommend replacing your double-glazed windows with A-rated windows to increase the efficiency of your energy bills.
