Double Glazed Window Repairs
Double glazing is an investment that is worth it, but can be frustrating when it fails to perform. Most issues can be addressed and you do not have to replace your windows or doors.
Double-glazed windows are made up of two glass panes that are separated by a very thin gap. This gap is filled with an insulating gas such as argon. This increases the thermal efficiency of windows.
Broken panes
While double-pane windows are more 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 moisture and energy loss.
You can select a temporary repair or a more intensive epoxy fix depending on the extent of your crack. A temporary repair can help stop further cracks from occurring and keep out the cold and rain. A more extensive repair can reinforce the crack and create a better seal.
To replace a double-pane broken window, remove the frame and place it on an un-slip surface. Apply a grid of duct tap over the pane to prevent any glass fragments from falling off during removal. Once the tape is in place, pull the old double pane glass from the frame. Then, use a wirebrush to clean the grooves and rabbets. You can also vacuum or wipe them with a damp cloth. Remove the wood molding, if required and scrape off all putty or metal glazing points prior to putting in the new pane. Apply silicone caulk to the rabbets and grooves in order to ensure a tight fit.
If you're repairing a cracked glass by yourself, start by sanding it 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, you can use a blade for a putty to push the rope into position. Make sure the putty is a uniform thickness and is pressed against the glass and frame evenly.
If you're looking for a longer-term fix, an epoxy repair is a better option than a replacement. This requires more work and takes longer however it is more appealing and will last much longer than a temporary repair.
Condensation
Condensation is among the most frequent double-glazed window issues, but it doesn't mean that your windows aren't working properly. The fact that your windows are showing condensation is actually a good indicator that your double glazing is doing what it's supposed to keep the cold out and the warmth in.
It is actually water vapour from your home which condenses on the glass's surface when you see condensation. It's quite a natural phenomenon and it's not something that's likely to cause any harm to your windows unless you allow it sit on the surface for a long time.
The reason for internal condensation is usually a lack of humidity or low temperatures in the room. This creates cold surfaces, like windows, to draw in moisture with a high in dewpoint (the temperature at which water turns into a liquid). Humidity is also inevitable around kitchens and bathrooms due to the steam that comes from kettles, showers, and hot pots and pans used during cooking.
To avoid condensation, try not to hang wet clothes near your windows and always 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 correct gap (6mm is ideal) for optimum energy efficiency. You could also consider installing one-way air vents on your windows to further improve insulation. If you're still experiencing condensation, there's likely a problem with gaskets or seals and this is something that should be handled by an expert.
Draughts
A draughty double-glazed window is an indication that the seal between the glass panes has broken and will require to be replaced. This can affect the insulation of your home and could cause an increase in energy bills, so it's important to act as soon as you notice this issue.
A window repair service will replace the sealed unit for you, while restoring the effectiveness of your windows. They can also upgrade your existing frames to incorporate new energy saving features, such as argon gas filled glass units with thermal spacer bars that will reduce heat loss and lower your heating costs.
It is also worth checking the locking mechanisms of your double-glazed windows. Older uPVC window locks are notorious for becoming stiff with time however, it's simple to fix this issue by regular lubrication using a specialized uPVC cleaning product.
A professional double glazing business will ensure that the repair is completed correctly. They'll have all the tools necessary to ensure that your window is watertight and completely sealed. They can also repair any damage to the frame so you can take advantage of your new double glazing.

Smudging
Double-glazed windows consist of two separate panes with an air or spacer dense gas between them to create an effective seal that prevents heat from passing through the frame. They're an excellent option to reduce energy consumption and your carbon footprint. Double glazing may have several issues that could affect its performance and lifespan. This includes fog, condensation, and difficulties to close or open.
If you are having trouble opening your double-glazed windows it could be due to the weather. It could also be due to a problem with the hinges or handles. Cleaning them with cold water and then lubricating them may help ease the problem, but you should contact the manufacturer you bought your windows from as soon as possible to get it repaired.
If your doors or windows have become sagging or dropped over time, this is another common problem which can be easily solved by an experienced professional. It is also worth checking the warranty to determine what repairs are covered under this.
Fogged or foggy glass can be caused by moisture between panes. It's usually a sign that the seals aren't working properly or that your double-glazing unit requires to be replaced. This is a simple fix that can be done without the need to replace the whole window.
To correct this issue A technician will drill tiny holes to vent out any moisture that is trapped between the glass panes and the rest of the window. After the moisture has been removed the new antifog coating is put on and the window is sealed. Sometimes, the window will need to be removed prior to this can be accomplished but most of the time it can be done within the home.
Mist
Double glazing that is older may have a mist problem, especially if it occurs both in and out of the window. This is due to a failure of the seal designed to keep moisture and air between the two panes. This seal is created during the production of double-glazed units by sealing both panes with an airtight polysulphide seal or butyl seal around the edges and a spacer bar. This is designed to protect the window from heat and prevent the window from being leaking. If you have misted double-glazed windows, they can be difficult to remove and clean, as you'll need to break through the hardened seal in order to clean.
sash window repairs with mist is that it lets moisture to get in, which then causes condensation between the glass panes. This is because there is a large difference in temperature between the external and internal surfaces of the glass. The moisture is encased in the gaps, giving an appearance of milky. This can be very unattractive, and can be difficult to get rid of.
There are a number of companies who claim that they can fix your double-glazed windows that are misting by drilling holes into the unit and injecting chemicals into the holes which then absorbs the moisture from within. This is not a permanent fix and it's more cost-effective to replace your entire double-glazed unit.
The best way to avoid misty double glazing is keeping a good level of ventilation and regularly cleaning your windows. It's also an excellent idea to install extractor fans in kitchens and bathrooms and wipe windows with a damp cloth to reduce the build-up of moisture. If you're unable to prevent the issue, we suggest that you replace your double-glazed windows with A-rated windows to increase the efficiency of your energy bills.
