Watch Out: How Double Glazed Window Repair Is Taking Over And What We Can Do About It
Double Glazed Window Repairs

Double glazing is an investment that is worth it, but can be frustrating when it doesn't perform. Luckily, most problems are repairable and you don't need to replace your windows or doors.


Double-glazed windows consist of two glass panes that are separated by a small gap. This gap is filled with an insulating gas, like argon. upvc window repairs helps increase 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 break or shatter. It's important to fix a broken pane in double glazing as soon as possible in order to avoid loss of energy and moisture.

Depending on the severity of the crack, you may decide to use an immediate repair or an intensive epoxy repair. A temporary repair can help to prevent further cracking and will keep out cold air and rain. A more extensive repair may make the crack stronger and provide a better seal.

To replace a broken double-pane window, take the frame off and place it on a flat surface. Install a grid of duct tape over the pane in order to prevent any glass fragments from falling during removal. Once the tape has been installed, remove the old double-pane glass out of the frame. Next, clean the grooves and rabbet using a wire brush, vacuum or wipe them with a damp cloth. If needed, take off the wood molding and scrape off all putty or metal points prior to installing the new pane. Apply silicone caulk into the rabbets and grooves in order to ensure a secure fit.

If you're looking to fix the cracks in your window yourself, begin by sanding the rabbet until it's smooth and clear of gunk or paint. You can also use a heat gun to soften any glazing or putty points. Once the rabbet has been cleaned and sanitized, a putty knife may be used to push the rope of putty into position. Make sure that the putty is of a uniform thickness, and that it presses evenly against the glass frame.

If you're looking for a long-term fix an epoxy repair is a better choice than replacing. This method requires more effort and a longer wait time but it's more appealing and last longer than a short-term repair.

Condensation

Condensation can be a common problem with double-glazed windows, however that doesn't mean they are defective. It's a good thing that your windows are showing signs of condensation. This indicates that your double glazing is working just as it should, keeping out the cold and keeping in the warmth.

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 on the glass's surface. It's a natural phenomenon that won't cause harm to your windows in the event that you don't leave it on the surface long enough.

The reason for internal condensation is usually a lack of humidity or low temperatures in the room. This results in cold surfaces, like windows which draw in moisture with a high dewpoint (the temperature where water turns into liquid). It is also commonplace in kitchens and bathrooms due to steam from kettles or showers and hot pots and pans used during cooking.

Avoid hanging wet clothes close to windows and ensure that your uPVC frames are properly ventilated to avoid moisture buildup. It is also important to ensure that your double glazed windows are correctly insulated and installed with the proper gap (6mm is best) for optimum energy efficiency. You could also try installing one-way air vents on your windows to improve insulation. If you're still experiencing condensation, it's likely the issue is with your seals or gaskets. This is a job best left to professionals.

Draughts

A draughty double-glazed window is an indication that the seal between your glass panes has failed and needs to be replaced. This can impact the insulation in your home, and can increase energy costs.

Window repair services will replace your sealed unit, restoring energy efficiency to your windows. They can also upgrade existing frames with new energy-efficient features, including argon-filled glass units and thermal spacer bars to cut down on heat loss, and lower your heating costs.

It's also worth examining the locking mechanisms of your double-glazed windows. Older uPVC window locks are known for becoming stiff after a while, but it's easy to fix this issue by lubricating them regularly with a specialist uPVC cleaning product.

A professional double glazing company will ensure that the repair is completed correctly. They will have the right tools to make sure that your window is resealed and watertight. They'll also be able repair any other damages to your frame so you can enjoy your stunning new double glazing with confidence.

Double-glazed windows are tough and long-lasting, but they can develop issues because of weather or wear and tear. If you notice any of these issues contact your local double glazing repair service right away to get them fixed as soon as possible. You'll be happy that you did it. A double glazing installation that's well-maintained will give your house a an immediate sense of quality and will save you money on energy bills!

Smudging

Double-glazed windows consist of two separate panes with the spacer or gas in between. This creates an effective seal to prevent heat from getting out of the frame. They're an excellent choice to reduce energy consumption and the carbon footprint of your home. However, double glazing may have a range of issues that can affect its performance and longevity. These include condensation, fog and difficulty closing or open.

The difficulty in opening your double-glazed windows could be caused by the weather or it could be a problem with the hinges or handles, or the mechanism. It is possible to solve the issue by lubricating and wiping the windows with cold water. Contact the company who supplied you with the windows as early as you can to get them fixed.

This is a common issue which can be easily fixed. It is also worth checking the warranty to determine what repairs are covered under this.

Foggy and fogged glass can be caused by moisture in the panes and is usually the result of seals that are not working or an old double-glazing unit that requires replacement. This is a straightforward fix that can be accomplished without having to replace the whole window.

To correct this issue technicians will make tiny holes to vent out any moisture that is trapped between the glass panes and the remainder of the window. When the moisture is gone, a new anti-fog coating will be applied and the window will be sealed. Sometimes the window will need to be taken off, but in most instances, it can be done from within the home.

Mist

Mist can be a huge problem with older double glazing, particularly when it is present on the exterior and the interior of the windows. It is caused by a failure in the seal designed to prevent moisture and air between the two panes. The seal is made 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 designed to create insulation and prevent the window from leaks. If you have misted double glazed windows it can be difficult to remove and clean up, as you'll need to break the hardened seal in order to clean.

The problem with mists is that they allow moisture to enter and cause condensation between the glass panes. The reason for this is that there is a huge difference in temperature between the interior and exterior surfaces of the glass. The moisture is trapped in the gaps, giving the appearance of milky. This can be quite unsightly and it can be difficult to get rid of.

Some companies claim that 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. However, this isn't an end-to-end solution to the problem and it's much easier to replace the entire double-glazed unit if you are suffering from misting.

The best way to avoid double glazing that is smudgey is by keeping a good level of ventilation and regularly cleaning your windows. Use extractor fans to reduce the buildup of moisture in kitchens and bathrooms. Clean windows using a moist cloth to avoid this. If you are unable to avoid the problem, we recommend replacing your double-glazed windows with new A-rated windows to increase the efficiency of your energy bills.
